GPU Thermal paste?

Richards27 · Nov 15, 2015

My sapphire R9 270x toxic doesn't really run too hot, 40-50°C idle and 60-75°C load. It's just that under load the triple fans can get quite loud and can be kind of annoying, im not sure if this is a defect but I was wondering if changing the stock thermal paste to some Arctic silver 5 would help? What would the temp difference be and would it be worth it, at 40-50°C it is near silent so reducing the load temps to that would be amazing.
Thanks

Of course it would help, just make sure you apply it correctly. I took off my GPUs cooler to apply new thermal paste and saw a temp reduction of at least 10C.

Yep, to concur with the OP who posted, it will help. Just be VERY careful and use the right tools for the right job (correct torx# screw bit, etc.). I have a very efficient cooling design in my Nvidia EVGA SLI cards, so YMMV. I only noticed a 2-3C drop at max load. But when I had an ASUS reference 7770 card (single fan), I saw a drop 5-6C.

Yes, it'll help quite a bit. I highly recommend using a high quality thermal paste. Give Thermal Grizzly Kryonaut a try. Good stuff, easy to apply and comes off just as easily if you need to remount for whatever reason.

I replaced my ASUS DC2 7970's old sloppy thermal compound with a small bit of MX-4, overclocking was easier since then and I now stay in high 60s/low 70C under load and with an overclock. I'd recommend MX-4 because it doesn't conduct electricity and does not take any time to bond. (Silver 5 will bond over a longer period of time) I use MX-4 on both my CPU and one of my graphics cards. Make sure you eliminate all of your old compound before applying the new.

Note, your card seems to not have any problems, although it could possibly improve. I am sure that if you replace the old compound with new higher quality thermal compound, you should get better temps. When I removed my card, I saw that it had a huge glob of thermal compound everywhere, just apply it in a small amount over the GPU die.

meowmix44 :

Artic Silver mx-4 is one of the best thermal pastes you can buy, where as you stated, stock and cheap thermal paste actually is a type of ceramic, it hardens over time and effectively begins to become an insulator. Mx-4 is great because it is a polysynthetic blend made up of Non-Capacitive, Non-Electricity-Conductive, Carbon-Micro particle Based Thermal Compound that is also Non-Curing, Non-Corrosive, Non-Bleeding, And has Low Thermal Resistance ,High Thermal Conductivity Dissipating Heat Efficiently. Making it hands down one of the best thermal pastes you can buy. On the other hand the absoulte best is the artic diamond compound.

Uh, no....

Thank you for that link, I was not aware they developed a pure Liquid Metal compound. thats crazy. I wonder if its effective long terms and what the cons are with it. I know thermal paste has to have many qualities that are great in order for it to be good.

I don't recommend the liquid metal for a between the IHS and block mount. It has a tendency to get hard, crack, and need replaced, which can be problematic, because it's a REAL pita to remove. Stick with the paste.

Now, if you're delidding your Ivy Bridge i7 or something, then yeah....the Liquid Ultra would be killer for that.

Thats what I thought the downsides would be, its not a paste ment for long term application, more of just benchmarking, testing, and seeing how far you can push the limits.

I've been using TG Kryonaut since it released here in the states, and it's absolutely amazing....best stuff I've ever worked with.
