Best way to glue Heatsink to VRM

[SecretX]

Ok the story is: I bought a moba that doesn't come with VRM heatsink, and its VRMs turned out to be quite like the sun. I improvised some heatsinks from another moba that I got from an old pc, and I'm not sure if I should just glue them into the VRMs using Heatsink plaster or use a Thermal adhesive tape that I got from AliExpress.

I got the idea from this video

just use a thermal pad, then some hot glue on the edge. It will probably be better.

Not sure how much I would recommend hot glue on electronics. Yea it's an insulator so it's not going to short anything, but it just seems like asking for a lot of mess.

My point was it would stick better than thermal tape, and the thermal pads would be better at heat transfer, but yeah, I guess that it could be a mess to remove from the board if you put too much on.

But what about the Heatsink plaster? On the video seemed like it worked pretty well.

I have used thermal tape never had a problem, but have seen many  have problems.

If you opt for glue on the sides you should skip thermal pads and use paste.

 

I recommend a thermal apoxy. I think there is a guy on YT that make his own and is solid
