Super IO overheating

[Marin Georgiev]

When I play a game the CPU fan starts to spin faster and makes a huge noise. From 2250 RPM it goes nearly 4000 RPM. After about 15 minutes PC shuts down.

I downloaded a software to show the temps and found out my Super IO starts to exceed 65 degrees. My CPU cores don't go over 50 degrees.

I'm using "Open Hardware Monitor" as software. My mother board is FM2A55M-HD+ http://geizhals.at/p/1022712.jpg , Super IO that overheats is Nuvoton NCT6776F. I have aluminium sink and one CPU fan, haven't changed anything.

PC features: CPU : AMD A8-6600K APU, 4 cores 3.9GHz; RAM 8GB ; AMD Radeon HD 8570D integrated graphics card.


What should I do? What exactly should I buy if I need to?

Start by reading this: http://www.tomshardware.com/faq/id-2122665/understanding-temperature-amd-cpus-apus.html

It says that OHM does not monitor temperature correctly on AMD processors and you should download AMD Overdrive.

ALso the chip you refer to is the North-pr Southbridge (not sure exactly, but by looking at its location on the board and the boards manual, you should be able to determine which one it is. My guess is Northbridge based on the description here: http://www.sequoia.co.uk/product.php?id=1425

You should check that the chip isn't caked with dust or something. Use canned air to blow over it and clean it. Check for airflow obstructions in the case. And make sure your software is trustworthy. You may have a temperature issue, but it may just be misreported as to where it is.

Thank you! I've tried so many other things. AMD Overdrive worked. No way I could have thought about that!

So using AMD overdrive temps are normal? I've seen some posts here suggesting that one may need a top-down cooler on some AMD high TDP models to ensure good airflow over the motherboard components such as the VRM. Not sure if it only applies to the 125W and 225W TDP versions, but if you really have temperature issues on the motherboard ICs, then you may want to think about that as an option.

Temperature margin of CPU is about 20 degrees. I think it's good. I know very little about hardware I'll definitely research. PC doesn't restart or shut down, fan is kinda racing.
