nice article, would be nice to add the grizzly carbonaut and innovative IC graphite pad also, they are nice alternative to thermal paste

yup, just confirms my arsenal of paste is the best... big tube of Conductonaut and MX-4, and a small one of NT-H1... and a huge tube of Artic Silver Ceramique when I need to use as a throw away paste to test if it was the bad thermal paste in heating up laptops ... which is still good compared to generic goop... Zotac mini with conductonaut on core and MX4 in power mosfets, and a bit on the memory

HH you have any of those thermal grizzly carbon pads? It would be interesting to see how does it compare. Interesting test though. Little change from all those gpu/cpus.

Very nice review, from my own experience Conductonaut really drop 4C compare to Kryonaut when applying on GPU die, that and Kryonaut will dry out quickly at high temp (80C+).

also... the carbonaut was tested in LTT, and gamers nexus ripped a hole into it with derbauer.. I don't think it's bad... but for general testing before final final assembly or to use as a baseline comparing it to "best case scenario for stock thermal paste" instead of using it for extreme use.. MX4 is better than it, and the MX4 is dirt cheap

when I got my 6600K stock, with a 3570K bundled heatsink I passed my time in 70c town at stock settings with a EVO212 it dropped to 64loaded and a 4.2OC with conductonaut between die and IHS and then MX4 to the 212... it drops to 50-55c loaded and 31c idle, almost ambient temp

Excellent article, just in time for my build this weekend. luckily have a largish tube of Kryonaut. 🙂

Chris made all the work on this test, but we can certainly add some new TIMs and pads for a future update article. Just post them in this thread and we'll keep an eye out.

I confirm that those pad seem very nice on a computer i have done for a friend. the cool thing is that they are easy to use. It might be interesting to compare it to regular TG. *edit* btw it is nice to see that even the worse TG is not a bad one and do the job, not like in the past were the worse one were really bad.

MX4 is pretty bad nowadays. Loses all its properties in just weeks. And doing even worse. Nice temps you are only getting for a short term, but eventually you can end up with temperatures much higher, than before MX4. A lot of thermal pastes are actually drying out pretty quick and losing thermal properties. So longevity tests would be much more useful, than thermal.

going to have to call bs on that.

I'm surprised Arctic Silver 5 does soo poorly when it has a very respectable thermal conductivity figure. That's been my paste of choice for years. Time to switch up!

me too I've been using AS5 for so long that I don't remember but it's way more than 10 years.

no toothpaste paste or mayonnaise? SAD.

Using MX4 on my new 3900X build and very happy with it. Started with Kyronaut but found it hard to spread, even after warming it in hot water. When I removed the cooler it was almost chalky, so switched to MX4 as I'd had good experiences with Arctic Silver before.

My Thermal Grizzly Kryonaut waiting for Ryzen 3700X 😛 Bought it over a month ago. Also have Arctic Silver 5 in my drawer...

I have the same experience with MX4. After 2 weeks the Temp went up by 10C, and it looked all watery. I'll stick to Noctua NT-H1 on my CPU and GPU like i have been doing for the past 10 years. It doesn't dry out either. I recently applied new paste after 2 years and the temps were the same.

I´ve always used Noctua paste because it comes with their coolers so i can save some euros... But the only paste that stands apart from the others is the Thermal Grizzly Conductonaut, powerful stuff! But the fact that it can "destroy" MBs leaves me uneasy... I think i will continue with Noctua even if it´s worse. Nice article!

Thanks for this, nice article. I'd also be curious to see some thermal pad results like the others have mentioned.
