Redoing the CPU heatsink is probably a good idea, with Artic Silver being a
leading suggestion (previous poster has a good choice here). As for cleaning
off the leftovers from the last thermal compound application, try isopropyl
alcohol as a solvent, and use the good stuff that's at least 60% by volume
or stronger. You can also try a pure copper heatsink and fan combination
instead of the standard aluminum ones, since copper has higher heat
conductivity. Amazingly enough, most cases will stay cooler when you close
them up and use the fans set the right direction to feed air in the front,
and blow it out the back, creating a wind tunnel of sorts over the board.
See which way your fans are set and flip them over if they are blowing the
air the wrong way. Hope all this helps. :)

Subject: [PCBUILD] Mobo Heat Problems


Hi,

I have an Intel D865GBF mobo with a Prescott 2.8 Pentium CPU with 1G of ram.
I'm having over heating problems in System Zone 2 on the Intel monitoring
system  see the following url.
http://support.intel.com/support/motherboards/desktop/sb/CS-012552.htm

Judging by the diagram it appears to be one corner of the CPU zone.  Right
now I overheat just doing a virus scan and have real problems playing any
sort of games which are so old they wouldn't need any sort of current
graphics card(mine is an nVidia 256mb one).  Any suggestions on fixing
things.  I've cleaned everything with compressed air and a vacuum.  The CPU
fan does work and I'm thinking of taking the heatsink off and reattaching
things.  But other than when I first built it, I've never had things apart
and I'm worried about doing damage.  If I remember correctly the heatsink
and fan had an adhesive type thermal connection when I put it together.
Will that come apart without effort or do I risk trashing the processor?  If
things seperate OK what works for cleaning the residue off before I apply
thermal paste and try reasembling.

Any help you guys could provide would really be appreciated.  I have a
Cooler Master CM690 box with 3 fans and just oredered up 3 more.  But with
both sides off right now I'm still having heat issues and it's frustrating.

TIA
John
