I've recently make a bolt-on bracket for my CPU cooler, expecting lower temps (since the pushpins weren't seating it properly).
Not so! My temperatures are in fact pretty much the same as if I had the stock cooler on, clocked at 3.2 GHz.
I mean mid 30s idle, and high 40s - mid 50s when under load (60 - 70 with linpack)
What I think is wrong is that the current TIM I have might be old or dodgy, as my temps with a different (although still cheap) TIM used to idle at low 20s and max out at the high 40s, and barely got above 60C with linpack.
The TIM I have at the moment has the consistency of golden syrup, and I suspect its gone off or something.
Could bad thermal paste make this much difference? Should I go out and buy a tube of AS-5?
 
If the tube is older it may have dried up or seperated. My suggestion is to stop using AS5 as there are many better compounds on the market these days.
 
Yeah, that might be the case. So what TIM compounds would you recommend? I might also replace the TIM on my graphics card and NB while I'm at it.
 
give me a link to the TIM section of your local e-tailer and Ill point a few out. Hard to say off hand as Im not too sure what is available to you in AUS.
 
CM ICE Fusion is said to be 5-7 degreese better, and I know first hand the Noctua NT-H1 is better than the AS5 also. I say either of those over the AS5
 
Arctic Cooling MX2 and OCZ FreeZe are pretty good too, I have use them both on CPU's and GPU's without problem and they are miles better than AS5.
