HEATSink & EPOXY

[jmecor]

Are those really epoxy glued to the heatsink and the graphics chip. Just wondering.. because i remove the heatsink of my old TnT2, and see a white glue or something (EPOXY i think)..

After i remove the heatsink, i clean it, and now i want to stick it up again...

Question:
What should i use?

1.) Epoxy

2.) Or it requires special form of glue to stick it.

Thanks for any comments..

If you could take the heatsink off then it was not glued on - probably used the normall spikes through the PCB and used thermal paste. If you want you can glue the heatsink on permanentlly with Artic Silver epoxy paste but if the board supports the heatsink with spring clips then you may as well just use normal thermal paste.

alright!

But can I use the graphics card WITHOUT applying the thermal paste for the chip & heatsink? It was pasted before, but I was able to remove it easily.

Ignore that willy guy mate, hes just a bit grumpy sometimes.

Most graphics cards gpu's have a thermal interface material on them and the heatsink is attached by plastic screws or something similar keeping it in place. If your heatsink didn't have any screws holding it in place, then that material is either a thermal tape or thermal expoxy.

Just buy some more thermal epoxy and stick it back on the card. Or you can buy a thermal tape and see if that works. I would go the epoxy route if your sure you won't be taking it off again.

Just wondering, how well does that Artic Silver Thermal epoxy hold? I know it will keep it on, but how hard will it be to take off again? (say I want to change cards but keep the heatsink)

I use JB-Weld because it's inexpensive (available in the automotive department at Wal-Mart) and conducts heat well.

If you could take the heatsink off then it was not glued on

LIES! I've removed at least a dozen glued on sinks, I've even removed sinks after using JB-Weld!

Best thing to use if you want a perminant solution is something like Arctic Silver epoxy resin.

Part epoxy resin, part thermally conductive AS2.

Worked great on the core of my old Geforce2 and on the ramchips on my R9800pro.

Well I epoxied a cpu heatsink to the shim of my 9700pro with AS epoxy. Its on very tight. so tight that if I ever want to take it off, the shim will come with it lol.

Just as a matter of interest did you take them off because they were glued on poorly or did you pull them off not really caring whether you damaged the GPU or not?

I only ask because I have used the Arctic Silver epoxy stuff before and It is solid stuff - I can't imagine that you could remove a heatsink attached with it without using a lot of force and risking a damaged chip.

I haven't tried to remove a glued on heatsink so I bow down to your superior experience but I assume that you could only remove ones that are attached with cheap / low tac stuff.

Some stick better than others, but they usually only require a light pry with a knife to break the bond, even when they are well glued. I've removed them to replace them with larger parts
