I'm running AS5 on my videocard with an Arctic Mono Plus, the videocard never exceeds 50*C ever no matter the game. I know its fashionable to bash on AS5 now because its the mainstay for the past two decades but the stuff is still fine to use, never had an issue with it. Using it on my CPU too. CPU idles at 27 and rarely gets over 55*C in games. Run the stuff until the system is taken apart. It stays potent forever. I also found a 15 year old tube of it in my attic and tried it out and it works just as well as the newer tube without any separation.

Always interesting to hear differing experiences and opinions. Never bashed AS5, nor was I ever a fan. Hard to clean and got better temps from Shin Etsu X23 back in the old days, much to the shagrin of some. My large tube started separating badly after only a couple years at room temp. So the AS5 stays in my garage and is used on automotive ignition modules now.

TG Kryonaut is diamond based? Worried about scuffing surfaces? Better not use any aluminum oxide (a common abrasive) products either as it is just below Diamond on the Mohs hardness scale. Which leaves out virtually all the ceramic based TIMs.
It's not as damaging as other pastes. Personally, I still have some IC Diamond 7 from that debacle we had with them here at TPU, and I'll use it on some applications, but not others. I wouldn't use it on a bare die, or in a situation where I want a better paste (like on my 2600k), or on a HDT cooler (because the heatpipes are already thin, so I don't want to risk damaging them with such a paste), but I'll use it for basic applications... I believe I have some on my Athlon II x4.

i was told that watercooling paste is the best thermal paste for air heatsinks, is this true?
nope, all the same
just use what you trust, with water block or just HSF, no big deal

I never had a problem with AS5. Put a grain of rice (or so) on the center of the CPU, plant your cooler on top, give it a titty twister, then clamp it down. Its good stuff. Swore by it for years.. Honestly, I mounted so many times over the years, it does take a bit to perfect your technique, I can see why guys don't like it if you have only used it a few times. Clean up is super easy too, the key is 99% iso alcohol. I ran out of AS5 last year and haven't bothered to replace it yet. I am using the Chill Factor 3 that came with Le Grand Macho RT and True Spirit 140 Power. Its actually pretty decent. I usually don't use anything except AS5. I've tried the Noctua paste when I owned D14, it was ok, but I went back to AS5 lol.. ICD7 was ok, I tried it during their beta test. It was a bit thick, and scrubbed the ihs a bit. I didn't use it for too long.

I put a tiny blob in the center, put a thin plastic bag on my finger and then spread the AS5 smooth over the top of the surface until it has a thin but very uniform coating of grey paste, and then install the heatsink on top, seems to give me really consistently excellent results, rarely need to re-do.

MX-4 is easy to apply but temps are 3-5C higher when I'm using that compared to Kryonaut or Gelid CG Extreme for example.

I wonder. How much better is the best/most $$ paste compared to the worst/cheapest paste??

Do they have like "English racing paste" ? (<- attempt at humor!) (when I was a kid, they/we had 3 speed bikes refered to as 'english, & english racing bikes') (actually made in England), the q above is serious, tho , ,

I'm currently using Arctic MX-4 but I am a huge, huge fan of the Noctua NT-H1 (and H2) paste. :D

Kryonaut for most applications is fantastic, too. I don't use liquid metal anymore as I don't need to de-lid my current CPUs for 24/7 use. The 6700K that I do have in my bench rig is de-lidded using MX4 in the middle.

Define better... its like those 3 speed bikes, all it takes for worse paste is that you'll have to apply more force (fan speed) to get on top of the hill ;)

Better, more efficient heat transfer? Isnt that what the paste is there for in the 1st place?
