JB Weld... Is it safe for a PIII cpu?

[rudder]

I've sued this stuff before to attach heatsinks to video cards and it works great. I have an OEM PIII cpu I would like to attach a heatsink to. Has anyone done this before with JB weld on the cpu die itself?

I guess I could go out and buy a different heatsink with clips, but I am cheap.

Unlike adding a heatsink to graphics chip which the mfr didn't feel required one, the processor definitely does need a good heatsink and fan (properly attached)to keep it cool.

Since you weren't too cheap to buy an expensive CPU why run the risk of damaging it with an ineffective heatsink attachment and heat transfer method. Spend another $12-$15 and get yourself a proper heatsink.

The Golden Orbs run around $12 and do the job nicely.

i actually did it with an oem slot 1 650E and a gorb after reading at overclockers.com about a guy that does it w/ great results, and as it would be permanent, i would finally be able to stop the incessant tinkering/lapping/etc. it was not the right thing to do as far as cooling. temperatures went up across the board by 15F-20F. i finally got the balls up to try and pop it off, which was nerve wracking since JB Weld bonds like an mother f...er. after a bit of dremmel work and some serious pressure it popped without ripping the slug off of the PCB and is now happy again w/ plain ol' grease. moral of the story for me was that you can beat the sh!t out of one of these cpus and it just keeps on ticking. (i have lapped this thing on several occassions as well)

thanks! I was not too worried about the permanence, but rather the cooling effectiveness of the JB weld. I heard it was a good thermal conductor. I will definetly check to see if others have noticed a temp increase doing it this way.
