bad chip?

post #1 of 6
Thread Starter 
so I noticed my cpu was not entirely flat, in fact it was terribly warped. So I got to lapping it. I scraped it all down to the copper beneath, and polished it with 600 grit sandpaper, but temps didn't change. there are still some small nicks in the metal, and the very edges of the corners curve downwards. should I spend more time lapping, or would I just be wasting my time, because it may be possible that I just have a hot running chip, which would suck, since thats the whole reason I went watercooling, so I wouldn't have a hot chip lol. So yea, any input would be appreciated.

Actually the IHS is not suppost to be entirely flat, but curved at the edges

well did you buy this chip used or what it new? the heat sink should lat flat on the surface of the processor, a wave may not mean that the metal will stop the heat sink from sitting firmly against the unit to cool it tho.and either way I would not suggest sanding on your processor

I bought the chip new. its an i7 950 running currently at 4.3ghz 1.425v 45C idle 72c load. my issue is if i run it at stock (3.07ghz 1.25v) the temps are only marginally cooler, which doesn't make sense, I know my temps should be a bit cooler than this, this is what i got out of my 920 and TRUE120 setup. I am using coolermaster TIM (dont know any more about it other than its grey, low viscosity) with an xspc rasa kit

The rasa block is good. 72c load for a 4.3 overclock isn't too bad. thats about what I get on my 920. I would suggest using some different tim, you should be able to shave a few degrees off. Make sure you dont use too much. when it comes to tim, often less is better.
