4/2/11 Update: Full Review is UP HERE>>


Continuing with the bay reservoir craze, is one Danger Den’s Monsoon Premium D5 Reservoir.  Not only can you get one in all it’s durable acetal goodness, you can get it IN COLOR!!.

Special thanks to Geno (BoxGods on XS) from Danger Den for providing this sample.  I chose the green flavor because I’m an old Kawasaki dirt bike rider…go team green!..:)

The reservoir is extremely nice looking.  It’ll be a little while until I get testing done, but in the mean time, I’ll share some more pictures.

Simple pump inlet port is very open to the reservoir, no baffles.

Outlet port manifold cover and LED windows are glued in place

A lot of thought has gone into the LED controls. Push rods here, make sure long end goes in first.

Pump volute is a nice completely spiral shape ever increasing in radius. The outlet splits in the manifold to two ports.


The nice spiral shaped volute should translate to great performance and minimal stress on the motor bearing.  A true spiral shape is generally the most efficient form for centrifugal pumps as it allows the impeller to produce flow in all directions.  The multiple ports are intended to serve as splitting options for parallel loop (advanced split loop design).  My general first impression is very good, the acetal construction is of high machined quality, and there is a plethora of details such as the LED control module and pump cover that exhibits a high attention to detail.  Then there is the multitude of color options that should appeal to many system builders looking for personal color touch.

Of coarse there are several colors and variations of colors to choose from.  I love the green being a Kawasaki fan, but they have black, red,blue and variations of trim colors as well.

So, I’ve had my new 2600K system up and running good for a little over a week now and decided to do some exploration on water/core deltas.  One of the problems I’ve had with past CPU block testing on the Q6600 was the fact that it would not hold if ambients were allowed to fluctuate.  This in turn required that ambient temperatures were fixed (as much as possible) and that testing was done based on water/air deltas.  Unfortunately that sort of testing introduces a fair amount of error with the radiator/fan combination.  Minor voltage fluctuations or other oddities can make fan rpms vary which varies the water/air delta.  In addition any sort of radiator dust buildup between tests can also affect results to some degree.  For me it was more of a struggle to maintain any sort of smooth ambient temperature.  The best I was capable of doing was using an air conditioner in a close room that varied ambients up and down over a 2C range.  Over enough logging of data that would smooth out the bumps, but I still was never very satisfied with the controls.

Fortunately, things seem to have changed for the better when it comes to the new i7-2600K series.  I ran a few tests purposely varying the ambient levels.  I’m running about a 2C water/air delta with the quad radiator, but my house temperature was purposely fluctuated such that I had about an 8 degree change in ambient and water temperature.  The resulting informal tests produced nearly identical results which is great news for consistency.

While there are some important items to acknowledge in water/core type testing, it should provide a substantial improvement to testing consistency.

Here are those quick couple of tests:

That’s good news and should mean a rather simplified means to isolating block or TIM performance differences. Of coarse pressure drop is important to account for radiator thermal performance differences, but that’s easy enough to do and eliminates several variables.

I’ll see what I can do to round up a few CPU blocks to see how they fair on sandy bridge..


3-23 Update:

Still exploring and setting up for some CPU block testing.  Here are some of the Dallas one wire probes I’m deploying via the Crystalfontz.

Four Air Sensor for Information Only

Two water sensors which are the primary tools for comparison of core-water delta

Exploring loading programs, here is OCCT vs Prime 95 custom small 8K FTT:

Prime 95 is more consistently loading at the full 100% creating a smoother log

I find the logged charts fairly interesting.  They are a bit of a pain to create between the two programs because there are minor time errors on both Realtemp and the Crystalfontz.  Because of these minor errors, it makes matching them up a rather tedious Vlookup function combining effort.  I wish I could just push one button and get the above, but I can’t…it takes work.  I’ll have to work on some excel templates to make it less painful.



Pump Noise Testing Round 1 Updated

Posted: March 17, 2011 in News

I’ve been busy building and overclocking my new i7-2600K build, so excuse my lack of updates.  I did however add in the DDC 3.2 pump plus Koolance top test in with the previous results tested.  Oh and I made it to 4.9Ghz on Sandy Bridge, not bad for a once every few years overclocker like myself.  I tend to only do this when I upgrade hardware, and it’s been a few years since the last upgrade.

Here is a link to the updated Pump Round 1 noise testing batch

And some early screens of my new build clock..:)


Prime 95 Small FTT Load

I haven’t adjusted memory speeds/timings yet, but the chip was really easy to overclock.  I really didn’t run into any additional voltage needs until about 4.7 Ghz, and heat is not bad for an old worn out block that is oriented incorrectly.
