CPU overheating help

[itzmatey]

hey guys, i recently took apart my cpu fan to apply more thermal paste to my cpu because i was having problems with overheating with some games. i first used the business card to spread it but after putting it back together and turning it on it would overheat when i would start a game. i took it apart again and did the simple pea trick and placed it in the middle and just sat my cpu fan on top of it. put it back together and it would still turn off. i then used speccy to monitor the temp on my CPU and i would start a game and it would jump to 60 and get higher and higher before eventually turning off. im not sure how im supposed to fix it or whats wrong with it. the temp is fine when im doing nothing (currently sitting at low 20 whilst writing this.) it looks like my cpu fan is sitting on the cpu properly and its sitting fine. i have no idea what wrong. if anyone has an idea that would be great. cheers NOTE - just opened steam and it jumped to high 40c but dropped back down to the 20c. if that helps with anything

1. What cpu are we talking here?
2. Are you certain you cleared all remaining thermal past first before reapplying?
3. Are you certian your CPU fan is turning on (and is clean of any dust clumps)

1. CPU - AMD FX 8320
2. i cleared the thermal paste off with some mentholated spirits
3. and yes i gave it a decent clean with an air compressor and dosnt seem to be any dust clumps in it

60C shouldn't be a problem, how hot is it getting before shutdown?

It gets to about 80c then shuts down.

Can you turn up the speed on the cpu fan? Have it run full speed at start?
How is case/mb temps? Does cpu cooler get much airflow? Can you monitor cpu fan speed (programs to do so)?

It really does sound like a heat sink/thermal paste issue. My method of applying paste is to apply a thin coat on both surfaces: put a gob on cooler, spread it around, then use credit card and apply pressure going in all 4 directions to force the paste into ALL the invisible nooks and crannies, scrape off all but a thin glaze. Put cooler aside, repeat procedure on cpu: when done, you should "Almost" be able to read printing on cpu. Use less pressure on cpu to avoid damaging it
