And I thought my scratches were severe!
Hey guys, at this time it is likely fine to use kryonaut. I bought the 1g tube in central europe approx a month ago, used it on my 9900k and after seeing this thread (a couple days ago) i "tested" the tube by rubbing a tiny bit of paste between my fingers to see if it feels rough and it was pretty smooth. After that, i tried spreading it between two pieces of glass using the pea method. There were no scratches as far as i could tell on the glass afterwards. Im just gonna leave my nh-d15 be, im pretty sure the IHS & heatsink surfaces will be fine.
But Shac bought some a couple of weeks ago that seems faulty based on his pretty bad scratching.
This. Also, pressing two pieces of glass with your hand will not create the same amount of pressure as the cooler. You may or may not have Kryonaut without issues, but evidently there is still bad stock around which isn't a surprise as they never issued a recall.
Ouch, i did not notice Shac's situation was as recent. Didn't read through the whole thread post by post. I might check my ihs out sometime during the next week just to be 100% sure and report back.
and about the glass - im pretty sure im able to generate pressure equal to or greater than a cooler.

Glass is a lot harder than an ihs I would have thought. Is an IHS not copper alloy of some sort?
Coolers get screwed down against the IHS, and then there's thermal cycling expanding and contracting the two surfaces against each other. You won't do that pressing two pieces of glass together with your hands.

How long did it take to get a response from them? I have sent them two emails through the contact form on their website in July and still no response.Thought I'd give this thread an update.
I messaged Thermal Grizzly again regarding the bad batch of thermal paste from 2018 (small quantity I believe)... I got a reply a little while ago and they offered me compensation in the form of a new cooler up to the value of 100 euros and also some extra cash compensation through PayPal.
I can confirm I received a nice shiny new Noctua NH-U12A cooler that I'd picked (which is brilliant btw) and also a very generous amount of Kryonaut thermal paste... Two large tubes of it in fact, which should last me a long time! I also received some extra compensation through PayPal.
I have to give them credit where it's due for their great customer service. I really wasn't expecting the compensation they offered... It was a pleasant surprise. I was also told that apparently Roman himself had sent out the package.
They didn't have to compensate me and I'm sure plenty of other companies would have just swept something like this under the rug, but these guys really are great and I'm very grateful.
Cheers
Well, you guys were right. "testing" the paste by rubbing it between fingers or trying to spread it out between surfaces without giving it a few heat up/cool down cycles wont tell you nothing. Today i took my Noctua NH-D15 off to check the IHS and baseplate of the cooler - the cooler has the EXACT same residue on it like people posted earlier in this thread. I was able to clean the CPU IHS even though it was not easy.
This is how the baseplate of my cooler looks after kryonaut in use for approx 2 weeks. Used microfiber cloth and noctua NA-CW1 cleaning wipes to clean it as much as i could.

So yeah, i really do not believe that there were only 800 bad syringes produced early 2018 as there are still people all over the world experiencing the same thing almost 2 years later. I am sorry for recommending the paste before taking a close look at the cooler. I would certainly NOT recommend thermal grizzly to anyone.
and a question - should i expect the ihs/cooler to be in even worse condition the next time i repaste? i cleaned the kryonaut off and used noctua NT-H2 instead. I am now worried there might be some chemical reactions going on between the noctua paste and the kryonaut residue.

Thank you for checking and writing back about it @jansimek. Doesn't look too bad (mostly residue) but the signs are there (slight scratching) after just two weeks. Mine looked terribly scratched after six months and I've never seen that before with other pastes (I never tried IC Diamond which had similar stories about it, I think). Wouldn't worry too much about chemical reactions, it's more the solid chunky particles that are the issue. It looks like Thermal Grizzly have aimed for coolest initial temperatures at the expense of damage to IHS and cooler baseplate and as a result decreased performance over time and (probably) repasting required more often.
Noctua should be a safe bet among others with only 1C difference usually.
As for cleaning, try some Arctic thermal material remover and surface purifier. That stuff is great. Or isopropyl alcohol 90+%.

Hi jansimek,
these kind of "scratches" are normal and will happen with any high end paste which uses metal oxides as base materials (especially aluminium oxide). No matter how small you grind the particles in the end aluminium oxide is much harder than copper or the nickel layer and if you have a cooler like NH-D15 with a polished surface you will always see this kind of result. You would even see the same if you use toothpaste (which usually contains zinc oxide).
This is far from what we considered the issue from last year.
Best Regards
Serious?! I've never experienced this in my days of building computers at work or at home. What other establishments use this in their paste?
Yep, Kryonaught are now saying it's supposed to damage the flat/polished mating surfaces of the heatsink and IHS. Let's hope no one has used it on a delidded CPU, because it's now grinding metallic particles into the top of the chip.
I'm not surprised that information isn't in the product description or usage instructions.

Arctic Silver AS5, Noctua NT-H2, Gelid GC-1 and GC-Extreme all use metal oxides. That's based on a 5-minute Google session.
Metal oxide crystals are probably the most common method of producing high performance paste (i.e. not just silicone grease) because you can produce different shapes and sizes of crystals. The different sizes can be selected to fit in imperfections between the mating surfaces. That's exactly the point of thermal paste.
Heatsink surface damage has happened ever since enthusiasts started needlessly demanding mirror finishes. Beyond a certain point the smoothness of the surface is much less relevant than the flatness of the mating surfaces.
