Weird Question

[ShadowChaser]

Is the thermal compound used in PCs suitable for applications with temps up to 290C? Need to replace a heating unit in a 3D printer and unsure if I can just jam some arctic silver or mx-4 in there

Not sure where else I would ask this and clearly my Google-fu is lacking.

I have encountered similar issues, these compounds are usually polymerized and unsuitable. There are special silicon compounds that work that high and are also adhesives but there are also special compounds for heater elements

Thats why i mentioned it was an example, they will have to figure out what exactly they need however OMEGA therm is a good start

oh yeah forgot about this stuff, if you check out JB weld they have some different things like this stuff https://www.jbweld.com/collections/8297/products/j-b-extremeheat

Not really knowledgeable in the 3D printing space but a quick Google search yielded some recommendations such as copper paste or just Arctic Silver 5 even though they dry up eventually.

However, I came across one forum post that recommended this thermal paste that works up to 240C (They might have even higher temperature rated pastes but their site is horrendous to navigate).
I also recalled from an LTT video graphite thermal pads, these could work depending on the application and they are good up until 400C!
