Well my E8500 0909 cpu still on phase but my E8500 1808 is on different board/cooling
Here's my E8500 Q740A493T 2L7**** / **1808 for Prime95 @4000Mhz on 2 different motherboards with different cpu cooling.
Asus Blitz Formula with Dtek Fuzion/Thermochill HE120.3/Alphacool AP1510 @15v
vs
DFI LP LT X38-T2R with Corsair Nautilus 500
As you can see the Dtek Fuzion H20 setup is much better at cooling cpu with 47C load at 33.8C max room temps versus Corsair Nautilus 500 at 57C load temps in much cooler 29.5C max room temps. Hence, the cpu on DFI X38 + Nautilus 500 setup needing slightly more vcore of 1.312v load instead of 1.304v load.
Dtek Fuzion cooling = 13.2C CPU load to Room max temp delta
vs
Corsair Nautilus 500 cooling = 27.5C CPU load to Room max temp delta
