How would i re-attach a heat spreader on a socket 478 pentium 4?

[Maximilian]

Would super glue work? The heat spreaders been completely taken off and the black rubbery stuff that originally held it in place is still there.

How in the world did that happen? I imagine that you could clean it out, put a little bit of thermal paste in, then press it on and maybe like solder the edges of the spreader back onto the chip with a low-power soldering iron while keeping the spreader under constant pressure with a clamp or something. Umm. Good luck with that. Anyone else have any better ideas?

 

[Maximilian]

I didnt do it, its someone elses. I only have super glue, pritt stick, tape, and the hope that itll all be fine if i just sort of leave it loose and hope the heatsink holds it in place.

What about a small amount of cement? It can take heat right?

i think you should just forget about putting it back on and figure a way to make contact between the cpu and the heatsink as is. it's not gonna kill it, socket a cpu's used to come without a heatspreader like that so you had to cool them like that. i think i read somewhere where someone took the ihs off of their opteron and it still worked fine. you would actually get better heat transfer, if you could find a heatsink that would go down that low. perhaps some sort of heatsink clip mod or something?

just use epoxy and you will be all good. dont it before and worked fine.

Yeah i heard it gives better heat transfer. But i would still rather have it on.

Is epoxy like superglue or is it different?

I wouldn't worry about reattaching it. The heat spreader inside surface is supposed to be in contact with the top of the cpu. Put some AS5 or whatever you use on the top of the cpu die and set the heatspreader on it and install the heatsink. It will be held in place by the pressure of the heat sink mounting.

Whatever you decide to do, I think glue is a bad idea. Plastic melts.

yeah i thought glue was a bad idea myself...dude honestly if you attach it using some sort of compound that doesn't transfer heat well or you don't attach it properly then it probably won't cool well at all. i still think you should just leave it off and not worry about it, at this point that seems like the best option in terms of keeping the cpu from being damaged. now if you knew exactly what you were doing, then reattaching it wouldn't be an issue but you don't so i wouldn't even risk it if i were you.

 

[covert24]

yea its really not that big a deal to reattach it since they use epoxy to attach it in the first place. and it doesnt matter if it transfers heat well or not since your not epoxing it to the die, just the outer part of the cpu. But if you dont know what your doing then dont do it.

Just directly mount the heatsink onto the bare CPU core. That's how it was done with AMD Socket A processors back in the day, and still is with GPU cores. It'll be fine without the heat-spreader, just apply thermal grease to the CPU core *ONLY*.

 

[VirtualLarry]

The Intel stock heatsink for S479 P4 chips will work on chips without heatspreaders, it just fits down in a bit further. Try to find one of those heatsinks.

I've done this myself, to get a P4 Mobile 2.0Ghz CPU to work in a desktop 845P mobo, since the mobile chips lack the heatspreader.

use some thermal paste, and glue the edges with super glue. clamp with heatsink

 

[Blain]

Best Option = Leave it bare.
Second Best Option = Use Arctic Silver Thermal Adhesive (epoxy).

Caveat > Even using the AS thermal epoxy, thermal conductivity will never be as good as bare core to HS.
