    atm my cpu goes about 44c in a 20c room under full load with a 120.3 rad and 6 fans.. i'm curious, will a swiftec mcr320 and 1 mcp655 pump handle 2 5870 gpu blocks in addition to the cpu??

    It should, but you are going to need some good fans to keep the heat dissipated. Perhaps invest in a more high performance 3x120 rad. :toast:

    The reply poster mentioned a better 120.3 rad. I'd agree, http://www.sidewindercomputers.com/thpa3xra.html

    Thermochill PA120.3 is capable of handling ridiculous amounts of heat even with low speed fans. I use one for overclocked i7 and HD5870, but soon to be Fermi GTX 480. If your ambient temps are good, which yours seem to be, then you either need a better rad or higher speed fans. Although a 44 load temp is really good already. Just an fyi, you might not gain anything. Also, some boards sensors read hotter than others...

    Would it not be cheaper to buy a second MCR320?

    the coolance HX 1020 is a great, cheap and amazingly effectgive rad.

    right now its handling my i5 750 at 4.2ghz 1.35v and two OC'd and overvolted 260's just fine, with 3/8" tubing and 1200RPM fans. :D.

    But I would also consider adding another rad into the loop... maybe a 2x120 in the drive bays, up front?... or another 120mm in an open 120MM intake slot.

    an MCR320 and a MCR120 in tandem will spank any 3x120mm rad out there.

    you'll lose a lot of flow, might need another pump too.

    try to calculate heat dump with the extreme PSU calculator. Besides the CPU what else is in your loop??

    This will help you to select the right fans. And to determine what you need to keep the cpu temps within so many deg of delta. With the right fans on the PA 120.3 you can manage ~600 watts of heat and keep it within 10 deg of ambient.
