[SOLVED] CPU too hot

I have a Q6600, with an ULTRA Chilltec cooler.

I overclocked the CPU to 3.2Ghz (vcore 1.325). But anywhere past 3Ghz the temps were hitting close to 80c after prolonged Prime95 test, and my idle temps were around 39/40c which also seemed high. I cleaned out the Cooler with some compressed air and it dropped down the Load temps by about 5c.

Last night I decided to change the thermal paste, I cleaned up CPU with vodka and put Arctic Silver 5. Afterwards I went straight to prime95, Idle temps were down by about 3c or so and prime95 was running at 70c for the first hour, then every hour afterwards the temps creeped up, i got to 78c after 7hours running, and when i turned off prime95 my idle temp dropped very slowly only to 46c which is higher than before.

Is the thermal paste application bad? since temps changed. It was difficult to install this cooler because it is so top large and heavy and I couldnt reach under it easily to install the screws (which meant i accidently moved it a little or tipped it slightly)

Should I take it apart again and redo the thermal paste?
or
Should I get my old zalman full copper cooler, which has a broken fan, replace the fan with a regular 90mm case fan (i can cut out the bracket and mount the fan with a couple of small screws on the cooler and the fans are roughly the same size).

perhaps allow a few days for the second application of paste to settle.

7 hr stress test with prime 95 is too long u just need 20 - 30 mins of stress testing to check your temperature...so turn off your pc for 30 min before doing the test and do it or 30 min and check the results..

would i have burnt the thermal paste off? or something like that, cuz temps in first hour were good enough for me.

I am still tweaking the overclock on CPU, according to what I found on google, multiple times. I need to run prime95 for at least 12hrs with no errors, but If i do get errors i noticed they come within 15minutes. So I thought I just do it together, check last OC and temps

Make sure you did it right - http://www.overclock.net/t/289573/my-experience-overclo...

The chiller isn't that good according to http://www.overclockersclub.com/reviews/ultra_chill/7.h...

Is the electric side of it still working OK?

I think you need a better cooler for overclocking the Q6600. Try the Zalman.


it has just a direct PSU plug. so it can work. just dont feel like pulling out the mobo, but if i have to as last resort i will. thnx. I saw it was a shitty cooler after a few months that I bought it.

OK - then don't OC with a shitty cooler eh? It's not gonna do any good.
