Yup.
Today I have to do it once and I hope Thermal Grizzly will forgive me (well, we've already talked about it). But after being asked over and over again how the normal Thermal Grizzly Kryonaut differs…
www.igorslab.de
Though I didn't see it in the article being mentioned, but the only thing extreme about these two pastes are the extreme pump-out that will occur over long-term use. Pump-out with Kryonaut can come early. The Extreme might last a little bit longer due its better grade silicone oil.
I always recommend Hydronaut over Kryonaut. According to the article, it seems that Thermal Grizzly might adapt their pastes to newer conditions. They did launch a new company, Polar Therm, which will be competing with Arctic. I like to use MX-6.
For people who want to build a system with not as much maintenance. Just use a 'non-silicone' paste, well, all pastes contains silicone, but some contains more than others. As with all these things, do your research and don't read into the marketing. The numbers and the promises are wrong.
Sometimes you can get Cooler Master's MasterGel Maker on special, like the odd R100-something. Not a bad paste, but not close to the best either though suitable.
A trusted paste is Corsair's XTM70, but it expensive. Just get MX-6/4, price pending. I see some people use Halnziye pastes, but there are also many clones which isn't Halnziye, and some Halnziye is high on silicone. I use HY510 on DIY things because it is cheap, but I won't use it on something pushing ~75° Celsius. There are better grade Halnziye pastes. I have never used HY880.
Read Igor's reviews, he is doing some thermal paste database. Not all pastes are available here.
Otherwise, use phase change thermal pads. I still need to test the ID-Cooling pads, but it not Honeywell's PTM7950 neither a clone. Will see.
