To anyone listening, this is my last gasp before I chuck my PC out the window..

I'm going to start with my system specs before we go anywhere.

Motherboard: Gigabyte MA790X-DS4 AM2+
CPU: Phenom II 955 BE
RAM: OCZ Gold 1066 DDR2
CPU Cooler: Tuniq Tower 120 Extreme
GFX: XFX HD 4890
Case: NZXT Lexa Blackline (a small case, some say style over substance, but whilst small, it does have a strict airflow, case ambient temps never seem to get above 22C )


First off, I've been mounting and remounting my Tuniq tower due to TERRIBLE load temps. I've done some OC'in too but back to stock now as this motherboard makes me want to suicide, absolute junk. (randomly resetting bios with post cycles after reboot, cant touch the NB frequency, no CPU-NB voltage control. Very high temps on the NB; more on this later)

The TX-3 that came with the cooler was RIDICULOUS, couldn't spread it to save my life, it was like plasticine on steriods!, it just stuck to anything i tried to spread it with, how ANYONE could EVER spread this is beyond me.

I decided to mount the cooler using some Akasa TIM I had lying around. Seemed ok, temps werent too bad, but using a 1.44 vcore could tipple me into the late 50's once it even hit 61C. Enough of that I thought, something must have gone wrong, so I decided to maybe give the TX-3 a shot again, big mistake, after many expletives I remember that it just couldnt be spread and gave up, reapplying the Akasa TIM hoping it would make a difference. Sad to say, it didn't. Exactly the same results. So, yet again, I've decided to try and spread the TX-3 seeing how this is meant to be the dogs. I completely abandoned the idea of trying to spread it, and instead made two lines on the CPU, and proceeded to mount the cooler tight, giving it a little wiggle to spread the paste.

So here I am, idle temps = 29-33 C with CnQ enabled. Prime 95 for 15 minutes got me to 50 C for a split second, averaging at around 48-49 C. So... what the hell is up with that!?. This a tuniq tower for christ sake, and on a stock Phenom 955 @ 3.2 Ghz im getting 49 C max load!?. I might aswell just stick with the awful stock cooler.

The only factor I can think of at this moment in time is.. the northbridge. There's many a thread complaning about the temps of this MB's northbridge, temp software reports 84 C!. Apparently GB says this is normal judging by others inquiries to Gigabyte. For validation, the NB is ridiculously hot to the touch, 3-4 seconds of touching the heatsink and your finger is on the brink of being burned. The NB is close to the CPU socket so I thought this could possible contribute.

The CPU cooler's heatpipes are basically cold to the touch, certainly not warm, neither is the cooler which makes me think bad contact, but I just cant see how that can be... It's as tight as hell on the mobo, and surely 3 different applications of TIM are going to show some difference.


If ANYONE has ANY suggestions or ideas please make yourself heard, Im literally in despair about this.. :'(
 
60 degrees load at 1.44V sounds about right for me, what makes you think this is a terrible temperature?

Northbridge burning to the touch isn't good though, that will not help stability.
 
This is an AMD processor man, 62 is the max safe temp. I've seen people on 1.44 vcore at 3.8Ghz getting p95 load temps of 48-50 C. That to me sounds more realistic. I'm getting this on stock voltage and clocks!.

The AMD standard cooler was roughly the same at load temps, 4-5C higher at max load on stock.

The hot northbridge is apparently normal for this board, and others have tried sticking aftermarket heatsinks to no avail. The motherboard does strange post cycles too after the bios has been tampered with, seems like the board is just a POS. Sometimes my FSB OC will stay and the higher multi will appear in bios, but once in windows the multi is stock and FSB stayed overclocked.
 
Just a tip for plasticine like compound. Make sure the syringe is completely sealed (lid on tight) and put it into some hot water for a few minutes. This should soften it up and make it easy to apply/spread.
