It doesnt work very well at all. I'd just shell out and buy some AS epoxy, or depending on what you are using it for, a couple of dots of epoxy in the corners and thermal grease in the centre.

I read that the couple of dots of epoxy or superglue is not a good idea. Now, if only I could remember why!

Some people have reported good luck with JB Weld.

Its ok, but to be honest AS epoxy isnt all that much more expensive than JB weld.

tried my mixture..ended up doing a 3 way equal mix. tested it on an old card and it bonded well. triedit on my gf4 ti 4200 128 and it worked great... haven't o/c'd the card well, but the compound seems to transfer heat well, the sinks are as warm as the ram chips =)

Once I had a glaciator 2 on an XP1800+ the cpu was up at 90celsius, so was the heatsink. It was only contacting on one edge of hte chip. If the heatsink is in prettyu much any form of contact it will heat up to close to the chips temperature. A cold sink either means you are not in contact at all, or that the heat transfer is perfect, and you have a very efficient heatsink. If its warm to the touch, I personally wouldnt be happy. But then im a temperature nazi. Anything above 40c = scary to me. And I have a socket A sink attached to my northbridge!

I won't make a comment about the name and the previous post, but if a heatsink is working it gets warm or hot- heat is transferred from the chip to the heatsink.
You are correct however a cold heatsink indicates no thermal contact.

is using plain superglue ok on ram chips? I'm talking about it maybe soaking through or anything? I know it's not an ideal transfer medium but its probably better than thermal sticky pads.

revised...i didnt use arctic silver, i used OCZ ultra thermal compound..and as for the heat transfer, the heatsinks are about the same size (or larger) than the ramchips.

my thoughts:
hot cpu : hot heatsink = need a greater airflow over the HS
hot cpu : cold heatsink = not propper contact

anyway, good luck with the HS epoxying
