Resealing Delid CPU

Steel Reinforced Epoxy, love the sound of it.

Is it not conductive though, Steel reinforced ??

You make a good point. People have historically used it on RAM chips and similar, so not in direct contact with a die. I feel like someone must have splodged some on a component before and noticed if it shorted anything, but it's very possible.

It had me googling thermal conductive adhesives last night. Found some interesting results but quite expensive and not easy to compare to regular paste.

Thermal Grizzly Conductonaut 73 w/m, Coollaboratory LP and LU are approximately half that yet all yield similar results.

I suppose beyond certain point, especially below 100c, higher thermal conductivity in terms of paste is relatively unimportant.

Yep - beyond a fairly basic point, it's not the conductivity of the material, it's the conductivity of the interface region. I've never found the W/mK unit very useful as thermal pastes aren't there to conduct heat, they're used to fill gaps and make a thermal relationship better than silicon>air>metal. Consistency, texture, and real world results all matter more

More relevant to marketing that it is to performance I suppose. A bit like ‘premium’ thermal pads - cost a small fortune because they’re labelled more thermally conductive than regular ones.

This ashesvive thing seems worth a try to be honest. I’ll maybe see if I can pick up an ultra cheap deliddable CPU and give it a bash what’s the worst that can happen

"Everyone loves numbers! Bigger numbers is better right? More numbers than the other numbers guys, sell our products!"

 

[Bluntwrapped]

Yep that’s the way.

The number equates to self worth lol.

If you cheap out, then you’re only underselling how important you are

Funny old world!

Not sure if this matters now, when I sold my de-lidded haswell on fleabay, I cleaned the core off and put a fresh coat of liquid ultra on it, then stuck the lid down with a tiny dot of epoxy (araldite) its heat resistant, on each of the 4 corners of the IHS, then placed it as straight as I could get it, put a weight on it overnight to dry, then tested it in the morning, all working fine, packaged it up and sent it to the winning buyer.

Not sure if this matters now, when I sold my de-lidded haswell on fleabay, I cleaned the core off and put a fresh coat of liquid ultra on it, then stuck the lid down with a tiny dot of epoxy (araldite) its heat resistant, on each of the 4 corners of the IHS, then placed it as straight as I could get it, put a weight on it overnight to dry, then tested it in the morning, all working fine, packaged it up and sent it to the winning buyer.

Exactly what I did, on the logic that if I sell the PC, I don't want to worry about the buyer messing up the delid inadvertently.
