Liquid metal

random_matt · 14 Jan 2020 at 12:19

Is there such thing as not enough liquid metal? My layer could not go any thinner and have terrible temps. Mainly on core 12 and another one. Even have a copper IHS attached, so know something is completely buggered.

Put on both surfaces, as most reviews I seen did so I assume due to it being thin and make sure it has no gaps once you make contact.

I used it on my CPU Die > IHS > Cooler and GPU Naked Die to Cooler and did both surfaces.

I did, looks like I'll have to do it again.

Unless you’re delidding on a commercial basis and are looking to save on excess TIM, put more on the die and IHS than you actually need.

Just me, I'll have to have a look. I'll add a little more and see what happens.

Honestly a little goes a long way once you start to push it (away from your, do no spread towards yourself) using the inc foam tips.

Exactly how I started, if I went any thinner there would none on the die. I'll see what happens, have to get some acetone first, being a dumb arse I used super glue.

Super glue is brittle, no need for acetone. Whatever method you used to delid, will work easily on the super glue. Just apply some force and it should pop off.

May be useful for cleaning off the old glue I suppose. Go carefully, acetone is nasty stuff.

Some have broke their CPU using SuperGlue (think the kits came with SuperGlue Gel, it is hard and when the IHS flexed it can damage the PCB, I used High Temp Automotive Gasket Compound.

Well, I'll assume when using the tool the glue rips up the pcb with the tools force. So I would rather loosen up the glue first before taking it apart again, and yes I'll be opting for your method of sealant.

I think some of the dead CPU were not them trying to remove IHS later, it was in place use of the PC with the hot/cold contraction/flexing on the PCB in place that would be fine with silicon type glue that is not brick hard.

I read it here in delid thread that the bellow was recommended so bought the same (only used a dot in corners not right round ledges and if you do leave the small gap for "gas" to escape when it heats up.

K2 BOND High Temperature 350° C Heat Resistant Silicone Sealant BLACK Adhesive 21g

I'll have a look, assumijng they are mostly all the same. My tool is the rockit cool one, they recommended permatex black ultra.

Do you really need to glue it down? Just loose place it,the clamp will hold it in place

Id only worry about sealing it if you ever sold the cpu ect,

Just prefer to seal it, I don't plan on being on X299 forever. Acetone got rid of the glue nicely, to bad my copper IHS is dead as a dodo. LM is unmovable, Acetone and Isopropyl does nothing, even if I leave in soak (Sealed Container).

Lap it.

It is the underside, never used LM on top.

Some fine wet n dry sandpaper will remove it

Just did a far better job and let it stand for 24 hours. Gamer nexus allegedly suggest the temps don't really change, lets find out.
