Arctic Cooling MX-4 bad paste?

2 months ago I repasted my CPU and GPU with new thermal paste: Arctic Cooling MX-4. My max. temperature @ 3,33 GHz with cooling pad was about 80-85°C. Now over 90. Sometimes 95. I can't run prime95 without shutdown. 2 months ago it worked great. Should I get a better paste? ( I also cleaned the fan and the cooling system complety 2 months ago.)

 

I think that maybe you just need to re-paste it better.

The paste itself is high quality - now, get the application technique to the same level.

You may need to keep in mind some things like tightening the screws properly and evenly and maybe even doing a couple of test applications and then pulling the heatsink off and seeing if the cpu was evenly and 'properly/lightly' covered.

Good luck.

 

Ok I will test it, but what's the best technique?

 

Straight from the horses mouth:

See:
Arctic Silver, Inc. - Instructions

 

For rectangle dies, I use the vertical line method (or horizontal depending on which way the die is positioned) and for small square dies like on some mobile GPUs, I use the pea method.

 

Your problem might easily be down to your CPU.
Its an X9100.
An C0 revision of that CPU will have serious heat issues. At first, it will run fine under load (around 70 to 80 degrees C under load), but then it inevitably starts climbing after a time it would seem.

E0 revision of X9100 doesn't have thermal issues and is more stable in that regard - but its also sold as a premium item which is difficult to find (not to mention expensive).

 

That's not a bad paste, but I highly recommend trying ID Diamond paste. I just installed this on four of my laptops and noticed an average of 6* across the board with one dropping my 11*.

 

Yes, it's a C0 revision. I repasted the CPU, GPU and I pasted the heatsink as in the manual of the Arctic Silver paste. My max. temp in BF3 is about 77 and 75 on the cores. Before it was 95 and 93. I will test IC Diamond soon.
