High-Temperatures on a well-cooled machine

[LyonesGamer]

In the past few months I've taken up somewhat of the computer-building hobby, shortly after I was given a fairly nice new case back in August. After I managed to somehow damage by motherboard during work on it, I decided to begin upgrading my whole system.

Currently, I've upgraded to an AMD FX-8350 CPU (with a corresponding new AMD 970 motherboard), 32GB DDR3 RAM, and a GTX 660 Ti GPU. However, shortly after installing the motherboard, CPU, and RAM (the most recent upgrades), I noticed a significant problem: namely, that it overheated. Thankfully the BIOS with the motherboard allows me to monitor my temperatures. It turns out it runs at about 60C while idling in the BIOS. If I boot into my OS (Windows 7), it shuts itself off after only ten minutes or so, and will not reboot without fully shutting off the power supply and allowing everything to cool down.

This is in a case with four fans, plus the CPU fan. It has a rear fan, a side fan, two front fans, the CPU fan, and the PSU fan. This is also in a room which I'd estimate at about 15C. My mainboard stays at about 25C, according to the BIOS monitor, so it seems to be my CPU alone. I used silver thermal paste, which does seem to have been properly applied. Also, this is with the side open -- with the side closed (even with the side fan) it adds about 2-3 C. Also note that I am not overclocking my processor, it's staying at the 4GHz it was built for (and also receiving a Vcore of around 1.3V).

I'd also like to note that sometimes my CPU drops to about 55C, sometimes seemingly-randomly and sometimes with a corresponding Vcore drop (although this is also somewhat random, it seems) from ~1.3V to ~0.9V. However, it only takes about 10-15 seconds before Vcore returns to 1.3V and my CPU returns to 60C.

Any help with this would be greatly appreciated. As I said, I can't use my computer for more than 10 minutes without it suddenly cutting the power, making the computer near unusable. I've asked several friends who are also very skilled with computer hardware, and they've been stumped. I've gone so far as to consider water cooling, if it would help.

quite simply you fitted the heat sink badly , iv seen this many times and the answer is remove the heat sink clean both surfaces use no more than a small Perl of new paste dead center of the CPU.

place heat sink on it but don't secure until you have twisted it a few times spreading and fining the paste as it goes, then secure the pins in opposite corners

then the other opposite two, power on the machine go directly to bios temp and try and micro twist the block as it heats up for a few seconds , let it stand and check temp for 30 mins, rinse and repeat a second time if that didn't bring it down a lot.

get a bigger Copper block 3rd party air cooler and try and again
