thermal paste WITH thermal pads???

I'm in the process of redoing my loop, replacing thermal paste pads etc......came across this article on Tom's Hardware. Seems a bit redundant to me, but for the random case this is a viable and could possibly offer slightly better cooling. I can't seem to find anything ANYWHERE to support this. The very few things I came across were from the early 2000's and say DON'T use paste and pads.

If anyone is curious as to the possible application it's a Titan X with a EK block and backplate. Which I plan to switch from Prolimatech PK-3 and stock EK pads to Thermal Grizzly Kryonaut and Fujipoly pads.

It is a perfectly legitimate way to do heat transfer. OFC it's not as ideal as having the thermal pad at the ideal thickness to begin with but this works in a pinch.

Specifically to the GPU, I wouldn't hope for too much performance. PCB side cooling does have an effect but it's not huge because fibreglass is a terrible conductor and it will be the main bottleneck of heat transfer regardless of what you use.

Personally, I think this is pointless, especially if you use good quality pads. adding paste could actually increase the thermal resistance, and not help the situation, and be messy. I think the fujipoly pads actually have better thermal conductance than most pastes, so I would say skip putting any paste on the pads. This is all personal opinion though, I've never tested this.

Micro: I came across this looking for some comparisons between Fujipoly and Thermal Grizzly pads. Seemed a bit outlandish to me. But as in all aspects of life, sometimes the weirdest things provide the best results. Not to mention curiosity got the best of me!

Late: My train of thought exactly! But doesn't hurt to explore other options!

I frequently do this to make up for gaps that available pads may not fill, or to improve contact on irregular surfaces.

However, only a few performance pastes are completely metal free, and using ones with any metal filler at all can cause issues if you clean up the binder, but leave any of the filler behind.

The problem with pads that have very high thermal conductivity is that they are all extremely stiff and barely deformable. If they aren't sized precisely contact pressure will either be poor, or the pads will crack.

If I'm to understand you correctly Blame, you apply thermal paste to the backside of a thermal pad when installing backplates. Do you take this a step further and apply thermal paste on the areas of the waterblock where you place thermal pads as well?

Do you notice any improvements? If so, in your opinion would this be worth doing. What would you recommend as a metal free paste?

If the pad has the exact needed thickness then why do you need to add thermal paste? If the pad doesn't have the correct thickness then just get the correct pads. Have you ever seen a thermal pad developer sugesting to use his pads together with a thermal paste? I haven't but if there is one I would like to know.

Hi,
Only time I've seen or thought to add "just a little thermal paste" was so it might hold the pad in place a little better than without moving easily for reassembly.
Some pads are not very sticky and some are
EK pads are okay fugi or what ever are very brittle or just flat out tear easily.
I always wanted to try thermal grizzly pads haven't then though.

thermal paste WITH thermal pads???
