While our Core i7-3960X heats up the radiator, a pair of GeForce GTX 580 graphics cards heat up the inside of our case. Maximum graphics fan speed make thermal and temperature testing consistent at full load, while automatic graphics fan mode and a long idle period brought down temperatures and fan speed for our idle noise tests.

Almost amazingly, this lab’s reference Seasonic X760 power supply continues to drive unreasonable loads throughout our torture tests.

    Too bad we can't see the full build on the cosmos II. Maybe cooler master should have sent the storm trooper instead

    Should have put the rad in the bottom of the Cosmos II by removing the HDD trays. Seems like it should fit there.

    Also, Swiftech makes a sweet kit although I can't imagine the size of the triple rad. Using the Edge 220 myself, love it. Fits in my Antec 900 II.

Fits in my Antec 900 II.The Cosmos II only accepts a 2 X 120 rad in the HDD compartment. Its too bad that toms wasn't able to complete the build in the cosmos II. Maybe within the end of the year, Cooler Master will introduce the Cosmos S II and fix all those enthusiast complains that i read.

    The Nzxt switch 810 is a good overall case. Too bad they can't fit the rad to cosmos ii . May be they should try the svgtech h80 triple rad air cooler .

    theuniquegamerThe Nzxt switch 810 is a good overall case. Too bad they can't fit the rad to cosmos ii . May be they should try the svgtech h80 triple rad air cooler .Guys, I'm collecting suggestions for future uses of the left-over Cosmos II.
    1.) Yes it supports STANDARD 3-fan radiators. It just couldn't be compared to other cases if it had a different cooling system.
    2.) It can probably also be MODIFIED to fit the radiator used in the article.

    So, do you have a custom system suggestion? or are you looking for a modification article? Like I said, I'm taking suggestions. Thanks!

    For the Cosmos II, try doing a full build with a standard 360 rad in the top and a 240 rad in the bottom compartment with a 3960X cpu and 2 LCS 7970 from powercolor to show the lowest temps and highest overclock on custom watercooling build. Maybe do an extreme build guide or something like that with the cosmos II. Just a suggestion

    If you want to stick with Swiftech gear use the 240 edge kit down the bottom with a Swiftech 360 QP up top.

    It seems a bit silly to use a rad with bits tagged on the end, since most good cases would be designed without those bits in mind. I can see the apeal of using something that is almost like closed loop, but using one of the optical-bay resevoirs with built in pump might have put you fairly close aswell.
    I would like to see what else you can do with the Cosmos II, perhaps a 240+360rad built with just that case as others suggested.
