Kryonaut abrasive??

It's going to worsen contact if gritty. It's meant to fill tiny grooves left over from machining. Large particles aren't going to do that.

My thoughts exactly.think they have been a bit bum with where they scrape there source of paste from! Mean while i'l stick with my ever so expensive paste! £7 a tub mind plenty left to do brakes on many cars yet!
Copper slip!. Decent temps also.

I noticed this myself very recently on a noctua d15s. I couldn't believe that the kryonaut could be the cause so I thought I must have scuffed it somehow but nope, the marks are only where the paste has been and scuffing the cold plate of a mounted heatsink would be a neat feat.

Is this something isolated to Kryonaut?

I'm sure there was some etching on my Black Rock last time I had it off but figured it was just the way it was. I have never used Kryonaut, but AS5, MX4, NT-H1 and perhaps a couple others.

Might have to take it off again and have a look.

I've only seen it with kryonaut. I've never had the issue with paste in the past.

I've only used AS5 in the last 10 years and I never had this problem. I also think that this Kryonaut paste I have right now is a bit thick and less oily than AS5. Anyway, very disappointed by this paste. Close to 0 difference compared to AS5.

wow ? I have used ceramic and as5 .. first time using Kryonaut and it has enabled me to lose a rad (1 triple 120 rather than 2) temps are 8-12c lower but then I'm on water

Temps are 12 degrees lower just with a thermal paste and a whole radiator down? You've probably just reseated your cpu block better

I was also thinking that my Silverstone Heligon HE01 is maybe a bad cpu cooler, i have it for almost 7 years and maybe its was not really made for 180W+ heat dissipation. (Although it says on website 300W). I was thinking to buy a R1 Ultimate or a D15.
Or should i try to repaste it using the pea method???.....aaaaaaagh...so many choices. I also was thinking of sanding the cpu IHS and cooler to 1200 sandpaper.

What are the implications for cpu rma after sending them these marked cpus?

Of course there is a "Difference"! your pocket is a lot lighter!!

It's been three days since my email to those idiots from Thermal-Grizzly and still no reply from them. What a bunch of ********!

michty_me · 24 Apr 2019 at 19:34

Thats a bit poor. Where are they based?
I might try some Noctua stuff next.

They are based in Germany apparently. And yes, i also would like to try this new Noctua paste, the NT-H2. Still, i read that Kryonaut is better for high watt output than any other paste.

It could well be but not sure if I fancy trying out now, especially after no support from them.

Seems about on par with many places now quick to take your case even give you a lift/push you to cash point!
But dam slow if anything isn't right and isn't just pc bits had it with some spanish Drongos over some fishing gear bits the Designed/made(F'd up)

MontesJr · 25 Apr 2019 at 12:29

Hmmm..i seems that after a second email complaining about the lack of support and the fact that i will expose to social networks my problem and their lack of support i received an answer in less than 8h...

"Hello Andrei,
i already forwarded your problem to our engineering team. We should reply to you in the next 24-48 hours.

Best regards,
Jannik Froehlich - Thermal Grizzly Support"

How about that????

michty_me · 25 Apr 2019 at 12:33

Hopefully they can get to the bottom of it then. They will probably want your tube back.

MontesJr · 13 May 2019 at 09:19

Just as a status update, i will examine the paste on a Scanning Electron Microscope with Energy Dispersive X-ray spectroscopy, we will get to the bottom of this. I was contacted by Thermal Grizzly support and we will be working together to see what is wrong with the tube that i bought.

sxshax · 15 May 2019 at 02:37

I have the same too. Googled, and found this forum. Do not know what further info I can provide.
Used Arctic MX4 for my Noctua NH D15S cooler with my Ryzen 2600, no scratches.
Bought a 9900k last week, migrated the Noctua over to my 9900k, bought Kryonaut. Reseated cooler a few times before starting up, because --- ITX case. No scratches.

Started up, load tested, temps were bad, 100deg during load tests. Reseated my cooler again. Unmounted my cooler, when I wiped the paste off with my 99.9% iso propyl alcohol with a microfibre cloth. BAD scratches.

Could it be due to heat?

MontesJr · 16 May 2019 at 09:22

Unfortunately it can not be from heat...maybe you didn't clean the paste to see the scratches when you reseated the cooler. More likely they were there.
