AMD 880G chipset is overheating! - Page 3

post #21 of 26

Yep, it seems I am running 125 W CPU...

403

Still, I have this build for like 1 year and with heavy gaming it didn't explode. How bad is this anyway? smile.gif

Heavy Gaming =/= Prime 95. Under normal operating conditions with no overclocking your temps are fine right? Your probably ok here, but running Prime95 or something similar puts undue stress on components and thus your high temps. If you wanted to overclock I would try to talk you out of it without additional cooling for obvious reasons.

Heres my edited first post

Seriously stop running p95 now and consider underclocking or locking cores on your cpu.

Removing your tower style cpu cooler (and going with a downdraft cooler like the stock one) may help VRM temps dramatically.

The Gemin11 would be good

Also these to stick on your VRMs for additional cooling

List of VRM failures


These MSI boards are pretty notorious for this, personally i would do something to address the VRM cooling on that board with a 125w chip for peace of mind.

Thanks again guys. I will do extensive testing tomorrow with my 92mm fan at various positions and will let you know how it went.

One last question: if I have to add another case fan what is better - a splitter or that 3-Pin to 4-Pin adapter (from HDD power)? Can the fan do PWM or it will spin at constant RPM?

If you use molex power (large 4 pin like HDD power) than you wont be able to control fan speed via software (in windows or bios). I would try a splitter first, so long as you arent using several splitters or really high powered fans I would assume that you'll be ok. Interesting thing to me is that you say you only have 2 fans and yet HWMonitor shows 4 fans @ 100%

You can see my CPU and motherboard in the screenshot above. I have a GeForce GTX 460 on board, but since Prime95 is a CPU test only I thought it's irrelevant?
I just found this:
http://www.coolermaster-usa.com/product.php?product_id=2754&product_name=Blue%20Ice
Could this help combined with a fan splitter?
Note, that I am not looking to overclock this system, just to get it stable as is.

No not the cpu heatsink.I'm talking about the North/South Bridge heatsinks. If you notice on the item you found (the cooler master blue ice) it has a fan and a heat sink. Some motherboards only have the heat sink without the fan. Under that heat sink there is thermal paste. Sometimes replacing that with better TIM helps wih temps.

Or even a good application of low quality tim can make a difference. That stuff is often just globbed on there, on the flip side sometimes there's effectively none there. rolleyes.gif

It sure couldn't hurt to clean that up and put a good application of TIM there. thumb.gif
