Which tools and materials are required to glue back a detached heatsink on S17?

[skylark_cash]

Detached heatsinks seem to be a pretty common problem on the S17 series antminers. My understanding is gluing back a detached heatsink is not that hard to do if you have the glue and maybe a heat gun, but i'm not sure what to buy to do this myself.

Can someone post details on which glue to buy and which heat gun?

The cheapest glue/adhesive or whatever you want to call it is the black glue form China, you can find it on https://www.zeusbtc.com/ , depending on where you are shipping it to - this might not be an option because it can't be stored in room temperature for more than 10 days, it needs to be stored in the fridge.

Another alternative would be Arctic Silver but it's very expensive, the good thing is you don't need much of that paste if you are only fixng a few heat sinks.

As far as the heat gun is concerned, anything will do, watch this video to learn how to fix the heatsink.

I don't see why they wouldn't, IIRC someone from the U.S said they ordered something from them, you can also check on Aliexpress, i believe it is the same product but a bit more expensive on Zeusbtc, but they have a good reputation and I have personally traded a lot with Kevin from Zeusbtc.

I've ordered from Zeusbtc with shipping to the USA. They were responsive and shipped out quickly. Just contact them via Whatsapp. Shipping prices can be pretty expensive.

The heatsinks are originally attached using solder, but removing and reattaching these with solder is pretty difficult. Getting the correct amount of solder is difficult, and you need to be very careful or you could end up shifting the chip beneath the heatsink. It takes a lot of practice to be able to do it reliably. I wouldn't advise attempting it unless you have the tools to diagnose issues after (test fixture, oscilloscope, multimeter...etc).

If you go the glue route, you're probably better off finding some arctic silver locally. Or some other thermally conductive epoxy.
