Crazy temps after lapping?

post #1 of 12
Thread Starter 
So I just lapped my cpu last night, and wow did it lower my temps... when its idle that is. When I go from Idle to playing crysis, or any game, my temps raise, and fast as hell. I did check to make sure it was an even surface with 3 differant razor blades, an old cpu's side, and the clip that holds on my heatsink. It was very even. I did mirror finish too. I did not lap my heatsink, I dont really think it can, and if you saw it you'd know why I think that lol.
Why is this?



Before = 39/49 I/L
After = 32/53 I/L

I think you achieve better results when both the CPU and the cooler are lapped, but as you can't do this then I'm not sure.

I think the temps go higher because they make a contrasting connection to the heatsink, the CPU is trying to output the heat faster but the cooler can't lose it fast enough, causing a bottleneck?

That could be completely wrong but it seems kind of logical in my mind :s

Either way, lower idle temps are always better.

You know, that doesn't sound half crazy.

Did you check the Heatsink base for flatness? Also, have you tried re-seating it? What TIM did you use?

Same tube I used to use, I bought a 17oz dynax tube of tim a long time ago and never finished it off, however this monday I'll be getting OCZ Freeze

You really need to get adventurous now and find a way to lap that heatsink base because now you did only half of the equation, sorta making it a little worse. Once you did the heatsink and apply tim, pre-spreading it if it's AS3 or 5 (with the mushier ones do the rice drop method), then you'll see your desired temp improvement..

its probably cause of TIM i had the same issue,re-applying Tim and seating it properly will solve the problem imo ..

If your using the stock push-pins after lapping, it might be that you took a few millimeters from the cpu and the push-pins cant compensate for that loss.
That means, you lost pressure between the cpu and the HS. I'd suggest you buy a bolt-thru kit.

Not true. A 140w CPU will always emit 140w's of heat. When you lap a CPU, you are increasing the efficiency of the transference of heat to the heatsink. This enables you to reach an equilibrium sooner, resulting in a lower CPU temperature.

I'm thinking that perhaps your load temper is higher than before because of a small air bubble. When the CPU is loaded, it's probably "aggravating" that air bubble, and causing trouble.

I removed a good amount of TIM and the temps dropped a lot, thanks guys, I'll also know that I didn't loose enough pressure because Its still hard to sit my heat sink. The OCZ Vendetta has a great holder for AM2/AM2+ mobo's, It forces you to apply a lot of pressure to seat it, and so theres no loss in pressure.
