thermal glue for VRM Heatsinks

P4Clock · 13 Dec 2018 at 20:51

i am looking for a none conductive thermal glue so i can put heatsinks of a GPU's vrm.

Whats my options please

My basket at Overclockers UK:

1 x Arctic Silver Alumina Thermal Adhesive (5g)= £7.99
1 x Akasa AK-TT12-80 Thermal Adhesive Tape= £2.99

Total: £14.46 (includes shipping: £3.48)

Sticky thermal pads are genearly used, you can get them in varying thicknesses and sizes.

Where thermal pads are used, there is still normally some other retention on the heatsink though.

E.g. pushpins at either end of seperate vrm heatsink

Think he means adhesive thermal pads

removable whereas thermal glue isn't, in case you go back to stock cooling

get yourself some Arctic Thermal Glue TG-003

Akasa Thermal Tape would be better as you can take it off again if you need to. With glue when it's on it's on for good. I used to use the Akasa thermal tape and never had a heatsink come off once it was fixed in place and I had some heavy copper heatsinks at times. It's the second one that Armageus linked to and you just cut it to the sizes that you need. Be sure to clean the bottom of the heatsink and the surface that you are applying it to with IPA to remove and left over residue.

I mix araldite and non conductive thermal paste 50:50 it gives a good bond that has sufficient thermal transfer and is not permanent.

I have use the adcive pads before and the problem in with a GPU been upside down when the VRM heat up(70c+) the glue on the pads softens and they fall off.

I used that tape with a big copper heatsink I made for the vrm's on a couple of gpu's (GTX480, GTX 780) when I used to use a core only block and they never fell off. The key to it staying stuck is properly cleaning both surfaces. The stock cooler's thermal pads leave a oily residue on the chips and if not cleaned off properly the tape won't stay stuck.

TBF i didn't clean the surface, how ever if they fall of the top GPU on to the back of the second it will be a costly error
