Thermal paste is INCREASING CPU temps, help!

post #1 of 28
Thread Starter 
I need some help with this, as it has seriously pissed me off.

Yesterday I swapped my Akasa AK-865...



...which is worse than the usual stock cooler as far as temperatures go, for a Scythe Shuriken BIG.



First time I used the thermal paste that came with the Scythe cooler and got temps of around 40C idle/65C load, which was higher than my freaking stock cooler and made no sense. I figured it was a bad thermal paste so cleaned it off and applied some Arctic Silver 5, which has increased temps even MORE! I got 60C idle and almost 120C load temps according to HWMonitor! After that, I cleaned off the thermal paste completely and am running it right now with no thermal paste between the CPU and the cooler, and I'm getting WAY LOWER TEMPS. Around 35C idle and 64C under Prime 95, which seems ridiculous.

Is it a bad cooler, or should I get a different thermal paste, since Arctic Silver 5 seems to fail hard?

And how did you apply it? A rice grain sized, dot method?

Rice grain in the center, smiley face and 5 dots are the methods I've tried with AS5.

EDIT: Almost forgot, the CPU being cooled is a measly 59W TDP Athlon 64 3200+. I've also changed cases from a crap £10 case with useless 2x80mm fans to a Fractal Define Mini with 3x120mm fans, it makes no sense whatsoever how I'm getting worse temps with a much better cooler AND a case with much better airflow.

Bad temp monitor? I've never heard of anything like this.

And 120C is hot. How did it not power off?

I was suspecting that too, but it eventually turned off as I have Thermal Protect on in the BIOS.

120C sounded ridiculous to me too, I'm sure the CPU would have blown up if it had actually reached that temperature. And the worst part is, the cooler (Shuriken BIG) was barely warm to the touch after it shut down, ridiculous or what...I'm suspecting it's the craptastic mounting system not making good enough contact with the CPU, but even when I press it down, it seems to make air bubbles so it still overheats. From the current temps of my cooler now without ANY thermal paste, it seems to be doing its job well enough for a cooler with no thermal paste, but am uncertain what to blame here yet.

What program are you using to take the temps?
120C, there is no way. It would shut off way before that.
65C is the max temp from AMD.

To much paste maybe? thats really strange

65C is the max temp from AMD.
70C is the max temp for my CPU according to AMD. Program I used to monitor the temperature was HWMonitor, made by same company that created CPU-Z. Not sure if it's a dodgy reading yet though.

This sound like bad mounting. If the PC did shut down from overheating then obviously something is wrong and it's not just a faulty sensor.

Bad mount maybe.. And how well is your case airflow?
