yeah that s why i want to build my own case (in that hifi "case") for now my 360 rad is sitting on the 2x 120 mm sort of grid @ the top of my inwin case...not really a grid but lot of lil holes in the metal and imo my rad cant breath correctly + i dont want to ruin the case by cutting in...of course i can add distance between the rad and the case but it already look like a babel tower and will result in too long tubing, which i dont want either....
other point is that with one of your last post i have realised that i was focused on the socket temp instead of the core one...---> gives me some degrees more to play before the limit temp
i m not a good example of custom loop for now, not as efficient as it should be, though the jump from the H100 to the open loop allowed me to run the 8350 from 4.7 to 5.00 ghz (i wasnt aiming really more tbh) ... so all in all i m already fully satifed but of course i ll try to go further like we all do
last point is i doubt i can cool my 8350 with vcore beyond 1.56v with a single pump , a middle class waterblock and 1x120mm & 1x360 thick rad (even breaathing @ its full potential)...if we speak about 100% on all cores in a long run under OCCT or IBT AVX of course.....if this happen i ll be more than happy and it will be new to me
on a side note i m never sure what voltage(VCore) we re talking about....bios setting or real one mesured during stress....my current Vcore is set to 1.5 with VHigh LLC and it peak @ 1.536 when i push the cpu....so if we speak about 1.56 v set in bios i m already scared by what i ll see via HWinfo monitor....if it s 1.56 v in monitoring it s not the same problem

For example, there is a difference betweeen 70c @v 1.45v and 70c at 1.6v. the speed of the pumps becomes more important. You can actually 'overpump' I know you are probably thinking that makes non sense from a guy with 4 x D5's in one system, however you can run the water through so quickly that you lose cooling efficiency and heat transfer. Also, fans with good static pressure are important as well. I personally do not go below 3.0mm H2O. Remember heat output does not scale with the % of voltage added, It is higher.
thx for the explanations, very informative for me Edited by UncleBlitz - 8/22/13 at 10:02pm
