Heat Sink Trouble.

[More Power]

I have two heatsinks that I need to join, they are somewhat loosly fitting and there are no screws to tighten them together. I was hoping to use some kind of glue but I'm not sure what kind would fascilitate heat transfer. Any suggestions???

Arctic Silver alumina (bicomponent) for a permanent fit.

Or, if ou need to keep the possibility to easily dismantle them, thermal transfer silicone glue from Fujik - DealExtreme: $7.77 FUJIK Silicone Thermal Glue (50ml Grease-Like)

I was looking at that, does it dry or remain in grease lke state when it has set? Thanks

Thats also what I was wondering - if it would stay solid. But, that looks perfect assuming it does. Thanx

No, this is not silicone thermal grease, it's silicone thermal glue ..... it harden more or less like transparent silicone glue, just need a little bit more time, and it's a bit less adherent than usual silicone glue (i mean the transparent one), but opposite to this, it transfer heat .....

Just for give you an idea ..... have you dismantled a PHR sled ? (who here don't have, LOL) ..... the white silicone that in the sled keep the corners of the heatsink and the chip glued to the sled , is this one .....


EDIT: this one, i mean

I have used this material and it sets hard but the bond can be broken with a little force, I think it's a pretty good thermal adhesive, at least untill some thing better comes along !

Cool, thats exactly what i needed to know. Thanks!

I think Ill go head and order some, as long as you dont know of anything stronger...

 

[HIMNL9]

As i said, Arctic Silver Alumina is more strong as glue, and still heat transfer ..... it's better if you are sure that you don't need to dismantle the heatsinks in a second time, cause it's like 2 components epoxy resin.

Ok, I probably wont, so Ill use this - thanx

I like to use FRYS.com*|*Arctic Silver
Its Uv reactive, and drys very hard ( A lot like any other A+B Adhesive)

or this might be more what your looking for,
