Does liquid metal TIM bond permanently between two surfaces?

DatGameh · Jun 23, 2017

I plan to delid my CPU some time in the future, and replace my compound with either the Thermal Grizzly Conductonaut or CooLaboratory Liquid Ultra.
After replacing the TIM, I plan to use epoxy to bond the IHS to the CPU. But, worried about the fact that the glue may create distance between the IHS and die, I'm afraid that I'll have to reopen it if temps go unpredictably high.

After some research, I heard that liquid metal compounds semi-solidify and keep two surfaces tightly together. Many call this a problem, but to me, it's a fantastic advantage.

If anyone has experience on this, how strong does the metal actually bond?

Nope, it stays liquid metal like, I used it when I de-lidded my 4770k, I used AS5 whilst waiting for my Liquid Ultra to arrive, 3 or 4 days later removed the AS5 and applied the Liquid ultra, I didnt glue the lid back down until I sold the chip 3 years later.

So when I removed the CPU from my computer, (3 years later), I removed the lid again, cleaned off the liquid ultra, applied a new thin layer to the die, and then with one of the tiny orange brushes that come with the liquid ultra, I mixed up some epoxy, and brushed a tiny amount, and I mean tiny amount to each of the 4 corners of the IHS and stuck it back down, I then put it back into the motherboard, and used the retention bracket to hold the lid firmly in place overnight while the epoxy dried, tested in the morning and all was working fine.
