5700 XT replacement pads?

Thinking about giving replacing the thermal pads (and paste) on my MSI RX 5700 XT MECH OC a shot in hope to lower the temps a bit, but I've never done it before and am unsure on what thickness for the pads I should use. Has anyone done this before who could give me some tech tips?

Really, you can just use thick globs of thermal paste. It's slightly more effective, but you need a thicker paste to do it. Prolimatech PK-3 is what I've used for my GPUs as a "total replacement" paste.

Isn't there a high risk of overflowing on the memory chips since they're so small, or do you just use a tiny amount?

The memory chips are about a half inch on the smallest size, and the contact points are underneath the chips. Use a full-on pea sized glob in the very center of the chip, and it'll both cool it sufficiently, and not overflow it. If you use a more liquid paste, or an electrically conductive/capacitive paste (like Arctic Silver) you will have significant risk however.

 

Thick paste, with low dryout, and not electrically conductive, is what you want. As long as you're not doing a vertical mount, any post-installation paste shifting will simply spread out along the heatsink, not drip against gravity up onto the GPU's PCB.

Do you use the same paste for the graphics processor itself or a more liquid-y one?

I have an Asus 5700XT and my best suggestion is to watercool it. that thing runs hot and even after i pulled it apart and changed the thermal pads and paste it didn't do squat. i dropped about 25c when i switched it to a waterblock.

Same paste. PK-3 is the least expensive per-ounce I've found that can get within 1°c of the performance of Kryonaut. The liquidity of the paste has no effect on performance.

A waste of money. Better to spend the extra on getting a newer better GPU than waste money on watercooling this GPU.

I haven't seen any posts about thermal pad thickness on 5700 XT boards.  Did you check the teardown videos?

I know the reference Vega 64 used 1mm pads, with either 1.5 or 2mm for one of the VRM mosfets.

 

Your best bet is to buy a 145x145 sheet of 0.5mm, 1mm and 1.5mm Arctic pads, then compare them to the original, and stack whatever is thicker than 1.5mm.  The prices increased a lot compared to last year however.
