GA-A75M-UD2H's HIGH Temperatures

post #1 of 2
Thread Starter 
Hello!
Recently I built a new system with the brand new AMD A8-3850 Llano APU. To run this processor I also bought the Gigabyte GA-A75M-UD2H Motherboard. I installed the stock cooler that came with the Llano APU, but afterwards I just went with a standard 140W AMD stock cooler that was laying around in my room. So I got better temperatures on the APU, that's great!
But since the beginning a sensor keeps showing a very high temperature on the motherboard. Lowest temperature on the sensor was 78C, the highest 98C. So that's really HOT! At first I ignored that sensor since I know that some are faulty on motherboards, but everytime I do something more demanding the temperature goes over 90C and the APU/CPU fan gets really loud. There are no issues with the APU, I felt the cooler and it's just warm, just like the sensor displays. But then I felt the heatsinks on the motherboard and they were pretty hot. It didn't burn my fingers, but after keeping it down for about 10 seconds it hurts. So it mustn't be 80C-90C, but maybe 65-75C?
What can I do?
Would taking of the motherboard heatsinks help and apply new thermal paste?
Would regular thermal paste be good enough, the same I use for my APU/CPU?

But I guess I'd void the motherboard's warranty then..

Please help me, the fan gets so noisy when the "scary" sensor cranks up.

Yes, I used SpeedFan to monitor that sensor and also CPUID HWMonitor.

Please help me! Thank you!

Re-applying TIM *SHOULDN'T* void your warranty, but I'd check with the manufacturer first. That would be my first step since a lot of boards come with really, REALLY crappy TIM, and in some cases, not nearly enough TIM is applied. As for the kind of TIM, whatever you use for your CPU will be good enough.

If that doesn't work, then I'd start working on airflow in your case. Add more case fans (if possible) and make the airflow nice and smooth (good cable management and thinking about placement of the fans and direction will help you out here). If after all that the MoBo is still running hot, I'd either go to water cooling or contact the Manufacturer and ask them for help.
