    Hi guys,

    I want to cool an i5 6600k @4.5Ghz and an itx gtx970 OC

    If my calculations are correct:

    i5 @4.5Ghz = ~150W at full
    itx gtx970 OC = ~220W at full

    full load = ~370W

    According to hardware labs http://www.hardwarelabs.com/nemesis...ew=article&id=12&Itemid=118#performance-chart

    the M160GTX can dissipate 400W
    the M182GTX can dissipate 440W

    a M160 or M182 will be enough to cool my system (CPU + GPU) ?

    Thank you!

    No, unless you can find some decent 80mm or 92mm fans with high static pressure which are likely to sound like jet engines if you do.

    I note that Hardware Labs don't quote the water temps with the dissipated watts so if they're 30ºC above ambient with the full 400/440W for example you'd be better with air cooling.

    I'd be looking at a dual 120mm rad as a minimum with decent fans.

    Thank you very much for your answer Big Elf.

    I saw these noctua fans http://noctua.at/en/nf-r8/specification

    53 m³/h 1800 RPM 17 dB

    Normally they should move enough air while sound quiet...

    The problem is that I have only 2x92mm and 2x80mm fan holes in my itx case.

    I have enough space to put a radiator for the 2x92mm while for the 2x80mm this option is available only if I install the fans outside the case (not best option for me).

    I will probably go for the M182GTX for the CPU, keeping my GPU aircooled and see if I can keep my temps around 70° @4.4/4.5Ghz....If temps will be around 50° (almost impossible) then I will add a waterblock for the gpu and see what happen :)

    Those fans are unlikely to be strong enough although they might just work for a stock or lightly loaded CPU.

    Never trust a manufacturers performance figures, you don't know what their test parameters are.
