10/10 this product is great!
I've been using Hydronaut now for quite a while, I bought the big 26 gram tube the first time (unfortunately I lost it so I didn't get to use it all) and this time I bought the medium sized 7.8 gram tube.I used to use Arctic Silver 5 a long time ago and it was always pretty good but it never really lasted too long before it became a solid and then trying to clean it off always made a mess. Hydronaut always remains paste and even though you'd think thats messier its easier to clean because you know it isn't half solid/half paste.Arctic Silver always performed pretty well under heat but Hydronaut just takes it to the next level I don't unfortunately have any tests to show you for temps and things like that but I can at least say it dropped my temps 5c on cpu. Not to mention when I repasted my 3080Ti with it it dropped temps significantly (although thermal paste fromnthe factory is almost always designed for longevity not for performance)

Expensive but worth it
Grizzly makes some of the best thermal dynamic paste for heat transfer.

Great stuff, much better GPU temps
I use this for both the CPU install and to refurbish a zotac rtx 3080 trinity oc I bought used. The gpu was a mining card and it ran HOT HOT HOT and consequently very loud when I received it. I thought I was going to burn the house down launching my computer into orbit by the insane force of the gpu fans gyrating at max speed. I thought I was SOL with my used gpu and my Skyrim ENB days were over, bummer. My son replaced the front thermal pads and noted the original thermal paste looked brown and cooked. A thorough clean and new Thermal Grizzly paste in a nice thin spread and the change is unbelievable. The gpu had totally gone stealth mode! Dropped temps 5 to 7 degrees, I can hardly hear the card at all, even when maxing it out. If you have a hot and angry gpu try this stuff and some gelid solutions thermal pads and get some peace!

Thermal Grizzley Extreme paste
Product arrived on time and in perfect condition. I’ve used Thermal Grizzley products and they perform well. CPU temps are always at 29 C and lower at idle. Heavy gaming temps run at 60 to 70 C. CPU is an Intel 13900ks. Would recommend this thermal paste.

Will it ever run out?!
Being a EVGA SR2 owner and fanatic I spend a lot of time repasting CPUs. I bought this to paste my chipset for my new waterblock originally but decided to put it on all my CPUs and my girlfriends and friends. I feel like I've repasted every CPU in my life and I've only used nearly half this tube.If I had to guess this is probably enough paste for about 30 CPUs - and it's top shelf stuff.I don't think I'll buy anything else - assuming this tube ever ends.P.S. a little screen in the tube to see how much is left would be super awesome- if it won't break the effect of the seemingly never ending supply of paste.Bravo

love the spreader tips but I don't see enough difference from $13 GENNEL G2
Ok i have used a lot of different TIM for GPU"s i use for mining and i have used the supper cheap GENNEL G2 High Performance Thermal Paste that i think was $13 for a 20g jar and i used this and i mean A LOT OF THIS and i do not see any difference between the 2 but the Gennel actually seems to keep the GPU core cooler by like 3 to 4c but as far as the higher temps of the memory the temps are the exact same between the 2 so im going to be using the much cheaper Gennel little tub with spreader just have to watch using too much as going from a syringe to a tub it was harder to judge the amount you are scooping out cause its not as easy to put back without it getting everywhere not kidding i ended up with some across my forehead that my wife thought was funny but just dab the spreader lightly just the tip and ur great so i will be keeping the almost $10 difference as really the name is huge not for this paste but for their liquid metal and high end paste but this i feel is just a grab for cash from the name

One of the best pastes to buy, just expensive.
This works thermal paste works really well with gpus and cpus. I mainly used noctuas nt-h1 thermal paste but I like that this thermal grizzly paste works a bit better and is a bit more thicker than the noctua paste.Temps keep my repasted 3070 under 67c, before it would hit 80c and fans would max out.My 5800x would stay under 82c under full load at 140w with a fuma 2 cooler and in a mb500 case. Room temps were around 76F.

Good purchase for long term builds and testing!
Reduced temps and application was very easy and smooth. I opted for pea application in the center of my R7 2700 and it dropped my temps idle by 5-7c compared to cooler master gel. On OCCT stress test it dropped my temps 10-15c!Great product. Used the GAMMAX RGB BLK 4 copper heat pipe cooler which doesn’t have the most level surface to adhere a cpu to. Very excited in the results.
