My E6300's stock cooler was concave bigtime

Which explains why my CPU ran extremely hot. I was idling at 52c and if pushed I could get it up in the 80s where it would throttle back to keep itself safe. I kept reseating the heatsink thinking I had goofed something up but it stayed hot. On about the 5th retry I put a very thin film of heatsink compound on the heatsink thinking maybe I had been over doing it and it ran even hotter. When I pulled it off again I finally noticed there was just an empty circle on the cpu where the heatsink compound on the very edge of the heatsink was all that was touching the cpu. Put a straight edge on it and you could clearly see a gap in the middle. Lapped the piss out of it and now everything is fine so if anybody else runs into a heat problem theres something else to check.

Well after looking around on here it doesn't seem to be as uncommen as I figured it would be. Guess Intel's quallity controll has gone in the crapper since the last one I bought back in the 386s days .

What are the tempuratures after lapping?

 

[thedarkwolf]

core temp says 44c idle and easy tune 37c. Tops out at 64c core temp and 57c easy tune at 100%. Still not all that impressive even clocked at 2323mhz but its better then near 90c at stock speeds . I could have done a better job lapping but all I had was 800 grit and I had to remove a lot just to get it level. If I really decide to push the cpu higher I'll probably just upgrade coolers anyway.

So, is this with the factory heatsink? What motherboard? Because, that's still fairly warm, for one that's been lapped.

Gigabyte P965-DS3 and yes stock cooler

I've read that lapping with anything higher than 600 grit doesn't get you very much cooling improvement, so you're probably fine.

Similar to me. Glad to hear that lapping it worked out for you.

BTW: it seems the best way to apply As5 or any compound to a CPU with an IHS is to apply a dot in the middle of the IHS and smash the heatsink down on it and twist it while pressing down to spread it around based only on the pressure between the heatsink and IHS. Then after a few days it will naturally creep to the edges of the IHS and heatsink and cover the entire area.

Hey thedarkwolf, you stated that after lapping your temps (using Core Temp) were at 44 idle and 64 load. Are you referring to the 'general' CPU temp or the actual CPU core temps? For instance, Core Temp shows each of my cores (E6400) at 45 idle. Using ASUS Probe II my 'general' CPU temp is anywhere between 29-33 idle. I'm using the Arctic Freezer 7 Pro, btw. Thanks for any input you can give.
