So I've got a brand new i7 920 D0 stepping with an GA-EX58-UD5 sitting in my Coolermaster ATCS 840. PSU in the bottom, standard fans/cooling with a Noctua NH-U12PSE, with the Noctua fans that came with it blowing directly towards the rear exhaust fan.
I have my vcore and vtt at 1.3, and my CPU temps shoot skyhigh, up to ~84 or so when I'm testing with OCCT.
I'm thinking that there's not enough air getting, since if I take the side off, the temperature plummet down to about 73-74 peak.
So what are my options, without spending a ton on getting a bunch of new fans? I've got one or two SFLEX E's I can use..
I'm thinking since there's barely a cm or two of clearance between the rear exhaust and the Noctua fan, I should take off the rear exhaust, and plunk it into the bottom as an intake?
I'm also thinking of flipping the top two fans, any success with that?
PS: The settings that generate these temps are:
19X Multi, 193 BCLK
QPI X36, Uncore x16, Memory at X8, so 1544, which my 6GB of OCZ Reaper 1866 should be able to handle fine.. timings set at 8-8-8-28 at 1T
CPU Vcore: 1.318, QPI/VTT: 1.315, CPU PLL: 1.3 (also tried 1.8, no difference), DRAM at 1.64 and rest at either 1.5V for PCIE and ICH I/O or 1.14 V QPI PLL, IOH Core and ICH Core.
Load Line Calibration enabled, All CPU functions Enabled except for Turbo and C3/C6/C7.
Also an ATI 5870 sitting in the case, but I haven't done any 3D stuff, so the heat it generates should be negligible.
Any help would be very appreciated as I've been tearing my hair out trying to get this stable, and it seems like it's OCCT stable, as long as I can stop it from getting above 80C!
