AMD 955 Black Edition ideal temps - first time builder please help!

Hi All,

First time PC builder & first time poster!

I've just put together my first build. I've got an
AMD Phenom II Black Ed. 3.2ghz w/ stock cooler h/sink
Coolermaster Elite 330 Case With Coolermaster eXtreme Power 460W PSU
Western Digital WD5000AAKS 500GB SATAII 7200RPM 16MB Cache - OEM Caviar Blue
Asus M4A785TD-V EVO 785G Socket AM3 onboard DVI VGA HDMI 8 channel audio ATX Motherboard
OCZ 4GB (2x2GB) DDR3 1333MHz Gold AMD Memory Kit CL9 1.65V
LiteOn IHAS124-19 24x DVD±RW DL & RAM SATA Optical Drive - OEM Black
MSI r5770 Hawk 1gb

Few minor problems during the build but got I've gotten to the stage where I CAN install windows 7 if I want (after about 10hours all told) but I want to make a couple things sure first...

I've got x2 120mm fans in the case although I might have installed them both so they are sucking air out rather than pumping in! Can anyone tell me if these temps are normal:

CPU 43-44c MoBo 30-32c in the bios H/W temp checker (I assume that's idle) . Cool and quite mode enabled.

One small problem I had with the build was seating the fan - I had to remove it and re-seat and some of the really sticky thermal paste that comes on the stock h/sink got stuck to the CPU?

I'm thinking of getting a new cooler anyway but do you think it's safe to install windows at this point, are those temps ok?

Many thanks!

Hi Tazz.

I build a 955BE last year with a 790FX GD70 but i didnt use the stock cooler as i wanted to OC. Personally i dont think its too high for idle, but also what is your ambient temp around you as that will affect the system, also have you done a stress test on it? Prime 95 etc.

I used a ALC coolit all in one but that failed, so now using a Titan Fenrir V2 which has my temps at 33 -35 idle and 45 -50 100%

For the fans you always have a push pull setup so a fan at front sucking in and a fan at the back to pull but more fans will be better and on the side as with your case.

That seems a little high for stock speeds at idle. AM2's run pretty hot due to the normally high Voltage they use. My overclocked 940 BE runs at 34 idle - 50 under load. also my mobo runs around the same too.

Personally I would remove the fan and thermal paste (use a little alcohol based solvent), get some silver based compound (like artic silver) and try again. You only a very thin layer covering the whole of the cpu.

Hi the CPU fan is going at about 5578c and the CPU temp stabalised at 45c mobo 38c - still in bios, any more thoughts or should I just get a better cooler asap.

OK. So since this morning ive installed windows 7 ultimate 64bit

In windows asus PC probe 2 is showing idle temps of only 32-36c!!!
Why so different from the HW monitor in the bios?

I ran Prime95 as suggested did the default stress test as i understand it, ran for 45mins approx and under heavy load the CPU temp didnt exceed 54c according to probe 2 again, error free also!

I'm really pleased everything seems great starcraft 2 is running like a dream with everything on ultra.

My only problem now is CPU-Z says my RAM is single channel but the asus mobo manual is really confusing as to which slots to pt the DIMM's to get dual channel - i think the sticks are in B1-B2 atm, do i need A1-A2 or A1-B2 or what?

thanks for the good tips earlier and if anyone has any idea why the temp is so diff in the bios or about the RAM issue please let me know!!
