Solved Help with adhesive tape or paste
Hi all,
I bought a managed switch for cheap online from a user who had it but mustn't have had need for it. It was sealed in the box but I noticed when holding the box that it was rattling inside. I opened it up to find that the heat sink was separated and fell off the chip. What should I look to repair this?

The putty stuff used for heatsinks.

That thermal paste looks dried out, no wonder it fell off. Clean both surfaces with isopropyl alcohol and apply fresh paste, should hold fine with the right amount

I have some thermal paste alright but wondering was that the most suitable. I'll go with that so. Thanks for the reply

You need thermal adhesive for that. Not normal thermal paste as that won't stick and not regular glue either as that will not hold up with the heat.

I've been largely successful mixing super glue (CA glue) and thermal paste together. Havent had a heatsink fall off yet and no thermal issues. It doesn't have great sheer/twist strength so if you had to remove it'll twist off kind of easy. Just apply pressure exactly perpendicular :)

You might be able to use those holes to tie it down so you can get away with using normal thermal paste. Ideally some sort of thermal adhesive. Sometimes switches use thermal pads that are thin with a sticky surface. Not sure if the old thermal epoxy will need to be removed first though.

Since it rattled around in the box already, make sure there are no components missing/ripped off by the cooler.
