Best TIM replacement for 4790k + delid question

[goodtofufriday]

Hello all,

 

My 4790k machine has been plagued by temp issues recently so i've decided to just go a delid and replace the tim. For temps what would be the best TIM replacement to purchase? And/or could I slap my Noctua c14s right on top of the 4790k die?

 

Thanks

Liquid Metal: CoolLaboratory Liquid Ultra or Thermal Grizzly Conductonaut.

And get a delid tool

Have a delid too already, actually backed the original on kickstarter way back when. 

 

 

Since I got you here, off topic, but what should I do with a 5820k? one fell into my lap. Havent figured out what to do with it.

yes you can do that its coled direct die cooling

its the  option

Coollabratory Liquid Ultra Gallium based TIM

 

Cooler direct to die will not work as the IHS provides necessary height for contact with cooler. I suppose using a straight thermal pad would solve the height issue, but your thermal performance would suffer immeasurably.

 

De-lid, clean the old TIM, mask off the die with scotch tape, coat the die with CLU (DO NOT get any CLU on pcb components or you will kill your CPU), glue the corners, let it cure, and enjoy. I saw 20*C drop in temps on my 6700k.

You can do it, but it's very hard to do and not worth it, you only get a few C lower temps by doing that, but you have to mod the socket or get a special tool to hold the CPU in place

I like using arctic silver ceramic poly synthetic compound when needed for non-conductive applications.

I like using arctic silver 99% pure silver compound when I don't have to worry about anything around it being conductive

 

The issue with a full delid is the retention arm holding down the CPU applies pressure on top of the IHS. Without it the CPU will just be flopping around in the socket.

Anything in particular recommended as glue? And should I place this in the cpu bracket to apply pressure for setting?

you don't have to glue at all, if you just close the arm while holding the spreader in place:

I used Krazy Glue, i'm sure there are better adhesives to use. i think locktight makes a decent one. just needs to be strong.

 

i should note, you need to remove all the black schmoo from the PCB and IHS before reattaching. remove the masking, place the cleaned IHS back on the die, and THEN glue the corners.

I still recommend gluing it in case you need to perform system maintenance that involves removing the cooler from the CPU, which would entail cleaning off the CLU and reapplying it... which isn't exactly easy.

no???? 

As long as you don't take the CPU out of the socket its not going to move?

oh, shit... well duh, right? friggin moron me. not enough coffee apparently.

 

still though not a fan of the idea that the CLU could move around much, especially on PCB mounted components near-ish by.

by I highly recomend not doing it

 just keep in mind that the liquid metal ones conduct so be carefull with it
