Welcome to my first kit “living” review, the new Swiftech H220 kit planned for release in late February. This is a rather unique product to water cooling as it is squarely aimed at combining the benefits of prefilled plug and play sealed kits and the expandable custom or DIY water cooling kits. While Swiftech has been in the DIY or custom kit business for some time via several innovative integrated options such as the H2O-X20 Edge, Elite, and separate component Ultima HD series, these kits are premium priced and require users to assemble and fill them prior to use which can be intimidating for new users. With the watercooling market filling with new users every day, many have been opting for the sealed systems such as the Corsair H100 or Thermaltake Water series due to their low price point and easy filled at the factory plug and play use. Unfortunately those systems are sealed not intended for expansion beyond the basic CPU cooler.

That’s where the Swiftech H220 comes in and as far as I know, the only system under $150 that comes already filled and plug and play in addition to being something intended for expansion.

This review will be the “Living” format in that I plan to release data and adjust my review and testing based on feedback I get through the comments. Please comment if you have any wishes of the review and test format.

Press Release

Swiftech® to unveil new H220 all-in-one CPU cooler during CES 2013

Long Beach, CA January 3rd, 2013 13:53 PST – Rouchon Industries Inc., dba Swiftech® is proud to announce the imminent release of the H220 CPU cooling kit, a new all-in-one liquid cooling system compatible with all current Intel® and AMD® desktop processors that will ship to consumers already pre-filled for plug-and-play operations. Setting itself apart from similar offerings, the product will also feature full expansion capabilities to include additional cooling devices for graphics and or chipset. The H220 will be unveiled during the Consumer Electronics Show held from January 8th to 11th in Las Vegas, NV and Swiftech® will demonstrate several systems featuring the new cooler capabilities at the Mandalay Bay Hotel Penthouse suites.

In a related announcement, the company disclosed that they had successfully developed and begun high-volume manufacturing of a new generation of Swiftech-made mini-pumps, specifically designed for the liquid cooling market. The pump combines a compact design, high-reliability (60,000 hours MTBF) and the high head-pressure performance characteristics necessary to drive multiple devices in the same cooling loop. Being PWM controlled, the device can be driven by any motherboard like a regular CPU fan. Thanks to this new pump and to substantial economies of scale, the company claims that their new H220 CPU cooler will offer thermal performance with a low to inaudible acoustic signature rivaling that of the best custom kits, all at the price of an entry-level product. In the words of Gabe Rouchon, the company’s Chairman and CTA, “This thing is ridiculously quiet; if the chassis light wasn’t on, I couldn’t even tell the system was running”.

Mr Rouchon also stated: “User convenience and the vast movement of novice builders towards liquid cooling was a critical consideration in the H220 design. It dictated that the kit would be pre-filled and completely plug-and-play. As a result, tuning and operations are as simple as using a regular CPU cooler. But with a 15 year heritage serving the enthusiast community, we also wanted to eliminate some of the limitations of the existing low-cost systems which are unable to accommodate add-on components because (a) they are sealed-up and offer no means to refill the system without voiding the warranty, and (b) the type of pump they use is not adequate to drive sufficient flow to cool more than a CPU. The Swiftech® H220 kit addresses both issues by featuring a reservoir with fill-port built into the radiator so that the system can be easily emptied or refilled by the user at will, and by our new high-pressure pump. It all seems that 15 years of innovation and know-how, together with some of the most extensive R&D we ever conducted have led us to this moment, and we are truly proud to present a solution that finally bridges the gap between full custom and sealed-up liquid cooling kits”.

The H220 CPU liquid cooling kit is maintenance free for the duration of its 3 year warranty period, and will be offered at a Manufacturer Suggested Retail Price of $139.95

What stands out to me as the critical spec above is the 60,000 hour MTBF of the pump, this means the pump (The one wearing part) is designed to operate 24/7 for 6.8 years. If you have been around in the forums, many of the lower cost kits do see problems from time to time and it’s usually the pump that becomes the problem. 60K is even higher than most of the premium DIY/Custom pumps out there (Typically 50K), so my hat is off to Swiftech for being able to specify a pump MTBF rating that high and that’s important to keep in mind when buying the economical kits. If a pump out there doesn’t come with a MTBF rating, you just don’t know what to expect. It could last a few years or it could last only a few months before failing. While I have generally had good luck with pumps lasting, most of the pumps I have used long-term were rated at 50,000 MTBF hours. Only time will tell for sure, but I really like the specification.

The other parts in the kit I know fairly well from the DIY/Custom side of things. The radiator core is an MCR220 QP and the fans are the Helix PWM. Also the copper base in integrated pump/block comes from the Apogee Drive II design.

All in all, a very nice specification package and clever idea to make the kit already filled and plug and play.

Welcome to my “living” review/preview of the Swiftech MCP 655-PWM DRIVE. What do you get when you couple our most reliable, most silent, and most cool running pump with PWM technology?

A Swiftech MCP 655 PWM-DRIVE!

I have been using D5 variants for about 5 years now and have always admired them as probably being the most tried and true pump out there serving many systems for 5 years + and going strong.


However, I have also recently come to admire having PWM control over pumps such as the Swiftech MCP-35X in which I was able to automatically speed up and slow down the pump to meet thermal demands. PWM is also of value for special reservoir tops and other cramped installations where manually getting to the pump speed control is difficult after installation.

With the added PWM features, you no longer need to touch the pump physically to change speeds and you now have the flexibility to control it manually or automatically through a variety of PWM controlling software.

A special thanks to Mark from Frozen CPU for sponsoring the pump used in this review.


Manufacturer Description & Specifications

In response to the overwhelming demand and popularity of the MCP655 Series has worked with Swiftech to bring you a more versatile version. Want your pump to run as quiet as possible? Now you can have that as well as the available power of the MCP655 in the all new MCP655-PWM. That is right, a PWM version on the MCP655!!

The MCP655 pump is a high reliability, high pressure industrial pump, featuring a 50,000 hour MTBF (5 year lifetime). Such reliability is afforded by the unique design of this pump, which contains only one moving part: the magnetically driven spherical impeller spins on a single ceramic bearing, thus extending the life of this pump beyond existing standards.

The pump is completely plug-and-play, and connects directly to any computer power-supply through standard 4 pin power connectors and a PWM 4-Pin header. It’s compact design, quiet and powerful motor make it ideally suited for heavy duty cooling in environments where space is at a premium.

This pump comes stock without any housing allowing you to integrate any of your favorite pump tops and pump accessories.

  • 50,000 hours MTBF (Mean Time Between Failure) equivalent to 5 years lifetime
  • Superior 12 Volts DC convenience: plugs into the computer power supply
  • The MCP655-PWM can be used with full confidence in any MP servers, and high-end workstations
  • Superior real world performance versus any aquarium pump we have tested to this date
  • The high pressure capability of the MCP655-PWM is particularly well adapted to high-flow systems using 1/2″ ID or 3/8″ ID Tubing
  • Compact Design
  • No maintenance when used with de-mineralized water, and anti-fungal additives (Swiftech HydrX additive is recommended)
Nominal voltage: 12 V DC
Operating voltage range: 8 to 24 VDC
Nominal power (@ 12 V): 37 W Max
Nominal current (@ 12 V): 2 amps
Motor type: Brushless, microprocessor controlled
Maximum head: 13 ft (4 m)
Maximum discharge: ~ 317 GPH (1200 LPH)
Performance will vary based on housing used

So, the hydraulic specs appear to be the same as the MCP 655, however there are some minor differences in the nominal power rating of 37W and operating voltage. The 13ft of maximum head is right in line with what I have measured myself with other D5 variants, but power consumption for my test bench has typically toped out around 21 watts or so depending on restriction.

We’ll have to put it through the ringer of tests and see how it compares. Perhaps there are some differences in RPM scaling over the vario model and perhaps the PWM feature allows a greater range of RPM operation.

Welcome to my review of the Koolance PMP-500, a new monster pump from Koolance with really impressive pressure specs.    I was instantly interested in getting my grubby little hands on one of these ever since I saw it come out just a couple of months ago.  Pumps and hydraulics has always been more fun for me than thermal testing, so I was naturally interested in this new beast of a pump.  While we do already have several great options, the competition between pumps is somewhat limited compared to other water-cooling products.  This one per the specs looks very interesting, so the question is, how does it size up in terms of size, pumping power, cost, and noise relative the other popular options like the PMP-450.

A special thanks to Tim from Koolance for sponsoring the parts used in this review.


Manufacturer Description & Specifications

The Koolance PMP-500 offers a high flow rate and very high static head pressure at just 12V. A mounting bracket is included.

  • Maximum Flow Rate: 16L/min (4.2 gal/min)
  • Maximum Head Pressure: 7.5m (24.6ft)
  • Motor: Brushless DC
  • Power Consumption (at max): 32W
  • Voltage Range: 6 to 12 VDC
  • Maximum Temperature: 60°C (140°F)
  • Electrical Connector: 3-pin fan header with tachometer speed signal
  • Hose Connections: G 1/4 BSP Threads
  • Noise: Less than 50dBA
  • Weight: 454g (1lbs)

Please note, the CTR-SPD12X2 and TMS-205 are unable to support this pump due to power constraints. For compatible speed control theCTR-SPD1224 is available.

Weight 1.20 lb (0.54 kg)
Dimensions 2.80 x 2.40 x 2.40 in (7.11 x 6.10 x 6.10 cm)

So, the specs are mighty impressive for sure in terms of pressure head.

DT 5 NOZ CPU Block Preview

Tags: , , ,

Welcome to my preview of the all new DT 5NOZ CPU waterblock.  He asked that I keep the internal details private at the moment, but I will attest to the internal design being something very different.  The name of the block itself says quite a bit, but I’ll have to leave you with your imagination on what’s going on inside.

For now I’ll just share with you some photos, DT’s product announcement, and my pressure drop test as a teaser.

I would like to give special thanks to Erik from  for the preview sample.



Xtremesystems’s announcement

DT 5Noz waterblock

Hello, let me present my new waterblock. I call it the 5Noz, as there is an unique nozzle inside the block with 5 openings.Martin was good enough to take these excellent pictures for me, thank you Martin!

I machine this block myself on my CNC.

I use copolymer acetal for the top and the spider. With each, I flycut the top with a slow speed and fast feed which gives it checkering like a gun grip. Because it’s a circular cutter, the pattern changes over the top and spider, very coarse near the center and fine near the edges. G 1/4 ports, of course, spaced very widely apart, so I don’t think there will be any fitting issues. There is a spotface at each fitting for proper O-ring sealing (can’t seal on the textured surface). Internally, the top has a couple of horseshoe shaped features that poke-yoke the nozzle so you can only install it in the correct orientation. The O-ring is kept round, which means super short cycle time for me to machine, but it’s also not fiddly to deal with, easy to reinstall if you need to.

The top and spider are also available in white acetal, I have parts finished but no good pictures yet.

The spider is removable and is available in Intel pattern, AMD pattern shortly, and this could be replaced for future socket designs. The spider has a pocket that the springs go down into. This hides the springs a little bit, but also the thickness of the material underneath the springs will allow a metal spider to be used instead of acetal.

The base is 110 alloy copper, 44 microchannels are machined in two steps 0.020 inches and then 0.012 inches. The base contact surface is machined flat and smooth, and is not polished. M4 female threads are in the base, which means that during disassembly for cleaning you only deal with metal threads, so less likely to strip something. The M4 stainless steel cap screws use the full head, so the hex wrench is a nice big 3mm size, less likely to be rounded out.

The nozzle is machined from 360 alloy brass and allows a unique flow path through this block. The nozzle is one of the best looking parts of this block, I wish I could share it, but it’s good and it’ll likely be…adopted…:rolleyes: The nozzle allows a flow path that contacts more fin leading edges, parallel flow paths, and provides a lower pressure drop. The base is bowed by the nozzle. One side of the nozzle is flat, and the base contact face of the nozzle is machined into a convex surface. Close tolerances must be held on the base, top and nozzle to get the bow to the 0.005 inches it’s designed for. To do this, I have to match the parts as they are built, as there are a few thou’ that parts when combined can drift. This means that it will be possible to custom assemble to any amount of bow. I think 0.005 bow is about right, but but I also think bigger IHS processors might do better with less bow, and smaller might do better with more :shrug: In any case, any amount of bow within reason can be specified.

The backplate is machined from 6061-T6 aluminum, and has machined chamfers to accept the heads of flathead M4 screws. This keeps the backplate and screws from slipping around when installing it to the mobo. There is a chamfer for LGA775, one for 115x, and one for 1366/2011. LGA2011 hardware is included, all hardware is stainless steel except for the springs which are zinc coated steel.

I’ve tested the 5Noz and the Koolance CPU-370 in my test loop.

D5 Pump with DT top, setting 5, 12V
Single 120mm radiator
Single Yate Loon D12SM-12 fan, 12V
Q6600 die simulator (copper block machined to Q6600 die sizes, Q6600 IHS soldered to these die)
200W applied to cartridge heaters in the die simulator

5Noz => 31.9C temperature delta between die simulator thermocouple and air entering the radiator
CPU-370 => 33.4C delta

5Noz => 2.55 GPM
CPU-370 => 1.27 GPM

Samples are with a few excellent, non-biased reviewers. Hopefully you can get some independent reviews of this block shortly.

Price will be $87.95 USD.


While my CPU thermal test rig is currently apart from my recent LAN event rebuilding, I do have the ability to test pressure drop very quickly.  So…I did and…
We have a new KING of low restriction in my 2011-2012 round of CPU blocks tested!
This block is a good 50%+ less restrictive than my previous next best grouping utilizing microchannel designs….wow!  It is the least restrictive microchannel block I’ve ever tested and nearly as low in restriction as large open pin designs of several years ago.That 5NOZzle is quite impressive in reducing restriction.
I should also comment on how excellent the machining quality on this block is.  Unlike some of the mass produced blocks which have minor irregularities, this one is excellence in precision and machining quality is as good as it gets.  All the parts come together with high precision and a lot of thought has gone into the design.  It is one of those blocks that comes apart and goes together as if you had a swiss watch in your hands, just very well machined with extremely tight tolerances and quality.While I don’t have thermal results yet, the restriction is exceptionally low, the machining quality is exceptionally high, and the design is something very different..:)
Thermal Preview 3-11-12
While I don’t have anything to compare yet, I did finally get my new 3930K processor up and running:
I replaced the standard M4 nuts with DD brass M4 nuts and 35lb springs which I plan to use for all of my 3930K block testing for mounting pressure consistency.
I figured as a placeholder, I’d give you a quick screenshot of my very first 3930K mount:
Still in the process of getting all my software installed, but I’m thinking I’ll hold back a bit on the the overclock at 4.5Ghz for some extra stability.  I’m pretty sure I could easily see 4.8+ out of this processor, but my old 2600K was pushing a bit hard and testing is hard enough without having to deal with occasional stability issue.  This overclock is extremely stable and the way I like it..:)  This is also pushing considerably more heat over the 2600K as can be seen in the water/air delta numbers hitting nearly 6C despite the strong full speed d12SM12 fans on a quad radiator.  I’m not quite sure what the actual Watt load is, but it’s very very high.  According to Tom’sHardware here, at 4.5Ghz it should be pushing roughly 175W. I wonder if that’s even enough myself considering system power consumption goes from 360W at stock settings loaded clear up to 516W (+156W).  Bottom line the 3930K is throwing out tons of heat, so this is a pretty good cooling test regardless of the final overclock used.
This is the first block I’m testing with the new processor, so I don’t have anything to compare with just yet.
Despite the very large LGA2011 6 cores and extra heat load, 4.5Ghz is still running fairly cool and a bit cooler than my 2600K at 4.8.
This is a new core distribution chart showing the deviation between core temperatures.  The first two mounts were done with the block lettering vertical to the left, where the last three mounts were done horizontal in line with the graphics card and motherboard lettering.  While the differences are within standard deviation error, my best mount #4 was with the block oriented horizontally.  My hottest #5 core and differences between cores was also better using the horizontal orientation.
I really like this block, it flows like crazy and looks good in my new 3930K based system.  I kind of like the white block with black spider option myself.  I did utilize my own mounting hardware for testing consistency and to make mounting a bit easier.  My only reservation would be the shipped standard M4 nuts that came in my package and stiff springs, but I understand the latest version is coming with large black thumb-nuts to improve the hardware package from what I recieved.  I measured the springs compression force and came up with roughly 20lbs per spring fully compressed which is a bit more stiff than I prefer using myself.  I used 8lb springs and brass thumb-nuts from the M6 which I plan to use for all my 3930K testing since it allows fully compressing the spring and feedback when complete so I can get a good measured installation force.  I also did not use the supplied aluminum back-plate since the 2011 platform has one built in but it looks well made.  In general the system is still very much a loose parts type system which takes a fair bit more patience and time to install than some of the more refined mounting systems out there that have reduced the loose parts down to only a few.
More to come as I get a few more 3930K based block tests done.


XSPC Raystorm CPU Block Preview

Posted: September 23, 2011 in Blocks
Tags: , , , ,

A special thanks to Paul from XSPC for providing the all new Raystorm block sample.  This is the next generation CPU block from XSPC which incorporates pretty much all new internals, a larger base, an illuminated block hold down, and the same easy mount back plates of the Rasa block.  I understand this isn’t intended to replace the Rasa block, but it is intended to be an advancement in performance.

Testing coming soon, in the mean time here are a few quick pictures.

Pretty much all new internally over the previous pin matrix and smaller base of the Rasa.  The only thing carried over from the previous generation are the back plates and hold down screw system.  This Raystorm is also sporting some factory LED lighting that give sort of a perimeter back light effect to the metal reinforced acrylic hold down plate. I have no doubt it will be extremely low in restriction with that large slot nozzle and deep micro channels and since the Rasa is already an extremely strong performer, this new block should be VERY interesting….

…off to testing..:)


Update 9-24-11

Completed the pressure drop testing and we have a NEW KING! of low restriction for 2011 generation blocks.  The new Raystorm is a good 1/3 the restriction of the previous generation Rasa and even lower restriction than the supreme HF.  That’s sort of what I expected looking at the deep channels and large slot nozzle.

First the detailed results:

And what good is a test without some comparative results:

Now for the painfully slow thermal testing piece.  We know that low restriction doesn’t necessarily mean optimal thermal performance.  Some times it’s a bit of a balancing act, but microchannels in general have been known to do both well where pin designs are generally more difficult to retain low restriction and high thermal performance.

And a couple more photos showing the retention hardware and surface finishing.

I am very pleased to see the clean lines of the new hold down plate of the intel socket.  The metal reinforcing insert has a nice matte black brushed finish, the acrylic edges leaves a nicely framed look, and the lack of any screw heads also presents a more modern and finished look.

The retention hardware is carried over from the previous generation Rasa. Only change I see is the additional metal washer and now loose hold down plate (not bolted). I’ll reserve my thoughts until I’ve gone through the multiple remounts of the block during thermal testing.
