Hello everyone.
I have mobo GA-990XA-UD3 rev 3.0, wtih FX-8350 overclocked to 4.3GHz. I have known problem with VRM throttling. First i did put a 8cm fan to blow to VRM(http://postimg.org/image/wpol49ynj/), and it did solve the problem, but it was too noisy. So i tried to make my own VRM heatsink. And this is what i made (http://postimg.org/image/ecjwgjy9b/). Unfortunately it did not work. I was just like stock heatsink. Prime95 with small FFT test was going about 4 minutes before motherboard started to throttle.
I was back to square one. Then i found an old AMD heatsink and i cut it, made it bigger than stock and put it on VRM(http://postimg.org/image/9o09xwu27/). Put Blademaster on CPU heatsink, and Xtra Flo on back of the case. So i thought it would help. But it was the same as the stock heatsink and the my previous heatsink. After about 4 minutes, CPU starts to throttle down to 1,5 GHz.
Then i noticed extremely hot south bridge even in idle. It is so hot that i can't even touch it for 1 second. It burns my fingers. My readings of temperature are obviously wrong, because it is saying in EasyTune6, that temp is 44 celsius. So my question is, could hot south bridge cause throttling? I beleive that the 8cm fan that was cooling down VRM was also cooling down the south bridge.
P.S. Mobo was throttling even at stock speed, and throttling usually starts when CPU reaches 55-57 degrees celsius. Throttling occures only in prime95. While playing BF4, i do not experience throttling.
Thank you in advance.
