How thick is your cold plate?

a LONG time ago I remember comparisons of cold plate thickness. I can't find them, I remember that thinner was not always better (maybe this is different?).

It would depend on the chip I would think.

I would say 1/4" is a good base figure though. For an AXP, I would go thicker, say 3/8".

For something with an IHS I'd go with 1/4" though.

So is a 1/4" enough for a Prescott?

I would be more worried about the pelt than the cold plate with a pressy.

I did some thermal modeling on that very question back then. The results somewhat surprised me, much more than about 5mm is almost a waste of metal. The thermal resistance of the metal comes into play and the heat spreading is very small. Go thinner than 5mm and there is almost no heat spreading, but very good heat conduction straight thru.

I have an a64 3200+ Think I should remove the IHS and use a 5mm heat spreader with a 172 watt pelt?

I plan on using a 226watt TEC, it should be able to do the job.
