Unboxing Review

The kit comes in a larger 9″x6″x13.5″ black printed box.


This is a universal kit box that is used for a few different kits.


This is the Intel Waterblock, RS240 Radiator,Black Nylon Reservoir,X2O 750 Pump.

The kits come with other options as well. While I don’t understand the AMD option since mine came with an AMD kit, I do get the Raystorm CU block since that is the all copper top. Regarding radiators, you could buy a more premium double thickness RX kit radiator or one of the other slim options EX or AX lines which are a bit more tuned for slower speed fans. Regarding the reservoir materials, I personally prefer the nylon for its extreme durability and I like the black look. The pump options include the lower cost 750 as we are reviewing here which produces about 1.8m of max head (6 watt) or the more expensive D5 variant which is good for a little over 4m worth of max head (21 watt). This particular kit costing less than $150 is more on the value side of things, but that shouldn’t discourage you. The pump is still plenty to expand beyond the kit CPU block and can easily handle adding a few GPU blocks and an extra radiator.


Kit comes mostly box inside a box packaged.


A plethora of parts to put together.

This is where it could become a bit intimidating for new users and how this kit is very much DIY. The kit is basically your typical custom water cooling parts put together in one box along with some little extras such as a power supply jumper, some external rad mounting brackets. The rest is basic CPU block, Pump, Radiator, Fans, Fan Grills, 1/2″ barbs, and a user manual. Speaking of the user manual, it is a nicely color printed letter sized packet

User Manual Link

If you are serious about installing this kit, you should read the following first:



Note in the user manual, that the kit and parts are covered by a 12 month warranty ;

The components in this kit are supplied with a 12 month manufacturer’s warranty. This
excludes faults caused by incorrect installation or improper use.

The H220 reviewed earlier comes with a three year warranty, so you are only getting about 1/3rd the warranty coverage here. I believe the Corsair H100i comes with a 5-year warranty, so only getting 12 months or 1 year is a bit short. I personally have typically gone about 1.5 to 2 years between hardware upgrades. While those 12 months may be short of the expected service life, it’s not going to inspire confidence that the product has a high reliability. There are really only two wearing parts in the kit, one being the pump, and the other being the fans.

This may or may not be a concern to you depending on your upgrade cycle.  I know my first water cooling adventure left me trying multiple pumps within months of tinkering, so as long a 1 year is good enough, and then we’ll move on.  More to come in further unboxing..

    Hi Martin,

    In your RS360 review, the out/in air delta was about 8.8 degrees for 1400rpm fans at about 200w of heat. In this review, given the smaller RS 240 but similar fan speeds and heat loads, I was expecting to see out/in air deltas of maybe 13 degrees? Otherwise, the air wouldn’t be able to carry away the same amount of thermal energy.

    However from your tests, the RS240 seems to be able to dissipate the heat of your overclocked 3930K with only an out/in delta of 3 degrees. This befuddles me, and I can’t understand how the system achieves thermal equilibrium. How is all the rest of the heat lost?

    What are your thoughts on this? Could there be some difference in your air temp measurements as compared to the measurements done in your radiator tester. Maybe the rest of the case air is mixing with the air out?

    Thanks and your site is a great read = ).

      Disregard the air out in these kits. It is located such that it gets cold intake air from the front case fan and really not useful or accurate. The air out in my rad bench is controlled and accurate but it is very hard to measure air out without some sort of rad test bench.

      That’s the downside of case testing. It better represents thermals and noise but harder to measure something like air out when you have air coming in all over the place. In the kit testing air in and core temps are really the only thing I can control very well.

    So this kit has everything needed to water cool? No need to buy tubes and screws?

    Hi! I realize this is kind of off-topic however I needed to ask.
    Does running a well-established blog like yours require a lot of work?

    I am brand new to running a blog however I do write in my diary every day.

    I’d like to start a blog so I can share my experience and thoughts online.
    Please let me know if you have any kind of ideas or tips
    for brand new aspiring blog owners. Thankyou!
