Arctic halts troublesome MX-5 thermal paste; MX-6 successor spotted at almost three times the price
Arctic's MX-5 thermal paste is no longer available and has been replaced by the MX-6. Although the latest version is not yet accessible on the manufacturer's website, it is now available on Amazon. The 4 grams version costs 28.75 euros including shipping.
Arctic appears to be retiring the MX-5 line of thermal compounds due to consistency issues. At Arctic, the product is now labeled "End of Life." A successor is already in the works: the new MX-6 which is available on Amazon. The firm faced quality flaws in specific batches at the start of the year. Affected pastes should exhibit irregularities in consistency and durability, resulting in a greater deposit of the oil included and premature hardening. This could obstruct the application of thermal paste. In return for proof of purchase, Arctic offered impacted consumers a replacement. The 4 gram version is 28.75 euros plus shipping, near;y three times the original price.

I made the mistake to not use TG kryonaut when repasting my 3090...+10-15° everywhere.....great.....I'm waiting a potential 7950x build to redo it but yeah next time I'll wait rather than use random paste I had laying around (my bad I know)

Have you tried MX-5? For me, it's not even about it being as good as Thermal Grizzly. It's about being able to remove a heatsink without damaging a processor. MX-5 behaves too much like a thermal epoxy. I used it the last time I mounted my AC eSport ONE.... When I went to remove the eSport ONE to replace it with my AIO, I twisted the heatsink back and forth until it felt like the MX-5 was breaking loose. Even with trying to lean the heatsink over to remove it, it still ripped my 5600X out of the socket. Then it took 2 people prying at it to get the 5600X off of the eSport ONE heatsink. It should never take that much effort to separate a heatsink from a CPU....
I switched from MX-4 to NT-H2 a few years ago, though I do still keep a tube of MX-4 around. I haven't seen a need to bother with Thermal Grizzly. If things ever get to the point where the small advantage that TG has over NT-H2 actually matters, it's probably time for more drastic measures than just a TIM change....

MX-4 is great, but i had a terrible experience with MX-5, the paste had way too much viscosity.

The tube of MX-5 I got is terrific, but I got the one which came with the spatula and have used that every application because of the consistency. I don't think I would like the results without using the spatula for spreading it thin.

Most people here have probably used MX paste somewhere down the line but since Thermal Grizzly came about then not so much. People want the best and MX5/6 isn't as good as Thermal Grizzly Kryonant or Conductonaut.
