Hello,

I just bought two new PC's both running under Win7 Pro, with 2600k proc is both. They are rendering 3D images in a small renderfarm. On PC shows CPU temps(CoreTemp) at 10-12° C higher than the other. there are differences in the builds which may account for this, but I am curious to see if i can reduce the heat in the hotter machine. hotter machine up 61°C. Cooler machine 49°C tops. Temp difference running same process, and even with the side off on the hotter machine.

Hot machine:

Fractal R3 Case
fans: 1 front, 1 back, 1 top
Noctua NH-C14 with two fans
16gigs Kingstone pc 1600 RAM
MSI GTX 560
Asus P8P67 M Pro


Cool Machine:

Antec 300
same fan config
Noctua NH-U12PSE2(less powerful!)
16gigs G.Skill RAM
onboard graphics(no card)
ASUS P8Z68-V-PRO

I thought maybe it was the grphics card that made the heat difference,
but I actually am looking at the screen of the hot machine through RDP on a third machine..

Anyway, i am curious as what anyone thinks about this heat difference. No overclocking on either machine.

Thanks,

Peter

I would say the problem is with the airflow in the Fractal R3 case, it's not keeping up with the C14 blowing the hot air into the case. Pretty sure the GTX560 is not helping either.
Another thing might of course be that the NH-C14 is not properly seated, but i would assume that would cause higher temps than the ones listed.

Antec 300 has pretty good airflow, especially with no graphics card. Most likely the fans also move more air than the 'silent' fans in the R3 Case.
