How do you secure a heatsink to the southbridge?

[Krk3561]

I have a heatsink from an old dell motherboard laying around and wanted to use it on a NF7-S's southbridge. What do I need to put it on? Will Arcrtic Silver 3 be okay?

i just used frag tape for my SB

Where can you get frag tape and what is it?

I heard a lot of people say they used JB Weld to secure heatsinks to chips like that because it bonds the pieces together very well, and it's a perminant bond... but I'd have to say, that will not work... because if you've ever worked with JB Weld before, you may have learned that it will not bond to aluminum... and most heatsinks you'll buy for a chipset are aluminum.
My advice would be to get some Thermal Adhesive from Arctic Silver.

Does CompUSA or RadioShack carry that stuff. cause I need it today. I have Arctic Silver thermal compound, will it do?

the newest 3M thermal tape is good, I'm using it for my SB and the heat transfer is definitely there.

You need either the tape like the last person mentioned... or thermal ADHESIVE. Compound or paste will not attatch the heatsink to the chip... it'll fall off as soon as you turn it upright... unless you have some other way of anchoring it to the chip... I don't recommend you even try JB weld, because it does contain metal, and if you slop it all over, you could short something out.

What stores carry either thermal tape or adhesive?

Thermal Epoxy, like Arctic Silver/Alumina Thermal Adhesive, but only if you NEVER want to remove it. Look for it at sites that cater to overclockers and carry Arctic Silver/Alumina Thermal Compound.
