EDIT: matter is fully settled amicably, with the help of the very good @Thermal-Grizzly support.

What can I say. Pay premium price, get premium scratching on both IHS and coldplate. Delidded my 8700K, only to find out what just 3 days of Kryonaut did to my D15S and the top of the IHS. Good thing I didn't put it on the die itself. The IHS was in pristine condition for almost 2 years of heavy use, mostly with Arctic MX3 and later Noctua NTH1. Kryonaut fixed the good looks.

You can see the clean IHS before the Kryonaut. I wish people would stop advertising this so hard. replaced it with NTH1 and temps are same, and it's far cheaper and not scratching anything. Quite sad.

Atleast its not conductonaut which corrodes
I used that on the die itself. It already started to interact with the back of the IHS, but that was expected. It's one thing to know that what you will do has specific adverse reactions, and another to expect a normal TIM application and to get scratching.
Oh and neither acetone or isopropylic alcohol can clean that. Luckily, temps seem fully normal, but I have to say, it looks like crap, both the IHS and the coldplate.
 
Urgh . . . I have some on my 1080Ti, but I've been meaning to replace it with MX-4 anyway.

It is by far the worst thermal compound I've ever worked with. Out of a 1g tube, I got 1 GPU application, with enough left over for another 1/2 an application. Most of what you put on top a surface gets wasted by it being impossible to spread evenly and thinly.

I really hope my GPU die is not scratched up.

Only one way to find out. Tear it down and post some pics maybe?
In my case, noctua nth1 seems to both spread better and give a bit better temps.

Me neither, and I've put that stuff nearly literally everywhere.

Still I'm using MX-4 as of late for paste applications. Cost reasons.
 
Oof, hadn't heard of this happening with kryonaut either

I use conductonaut for the high heat stuff and MX4 for everything else
 
I ended up applying kryonaut 5-6 times on a 3900x (motherboard issues, trying to figure things out before RMAing the board) and not a single scratch. Could be some defective batch(es) out there.
 
Never seen anything like that on my 6700k that had it´s coolers swapped three times, each time with Kryonaut. Neither on the coolers base plates.
Same goes for my current 9900k and 3900x and both of their Corsair AiO´s.

Spreading it though is a pain
 
Repasted my RX 480 2 times and my 1700x 3 times with some Kryonaut. Haven't gotten any scratching either.
 
I also use Thermal Grizzly Kryonaut, never seen this before.
 
i dont think a thermalpast can do that kind of damage

It can.. but typically it is the the ones with diamond in them where this happens

I've used this for years including multiple mounts on the same CPU and didn't have this issue.

Seems common. I wish I found that before buying it.

google for kryonaut scratching
You can google just about anything...

That said, how are there large (long) scratches when the thing stays in the same place the whole time? I'm wondering how you managed to get such large and LINEAR scratches across the IHS by simply mounting the thing. It doesn't really look like a paste and mounting thing to me...........typically that is pitting or much smaller length scratches. How you managed to make large scratches on the entire IHS/cold plate I have no idea. (looks like a cleaning thing to me).


EDIT: Worth reading - http://forum.notebookreview.com/thr...-properties-and-high-temp-degradation.829823/

Shows that they admitted to one bad batch back in the day... but this clearly isn't something that needs a PSA/sounding the alarm it seems.

EDIT2: support@thermal-grizzly.com

Email them.

with what stuff do ya clean it?
 
I agree with ED, those scratches are pretty long. For cleaning I use 99% isopropyl alcohol and a cloth. Everything comes off in a swipe. That's brutal.
 
Have you tried to contact them about it?

You obviously werent around during the IC Diamond fiasco on TPU so i'll leave these here for you



We even had the company CEO trying to bury the evidence. He had peoples damaged coolers sent to them for analysis then claimed they got lost in the mail or they never received them when their deliveries had been signed for by members of staff as proof of delivery.
 
I can believe it, all that went down just before my time here.

The abrasive quality of diamond dust vs whatever is obvious, diamond is about the hardest substance on earth and even in dust form will scratch things up like a pasty form of sandpaper.
That's why I don't, won't or ever will use it in any form for anything.

Right...buuuut... this isn't a diamond based product AFAIK...

Sent them an email yesterday. Luckily I kept the bag in which the tube came, which has a serial number, so maybe they can take out of circulation further defective batches.

They include a plastic "spreader" with the tube, so I spread it with that. I assume that contributed. The spreader is really soft though, you can't scratch metal with it if you try as hard as possible, even with the edge (tried it now). So when the messed up paste is spread, I think it creates those traces, and because they're covered in paste, you don't see it until you clean it.

As for the cleaning, about which somebody asked for, I don't think it's possible without lapping. I tried 99% isopropylic alcohol and acetone solutions, and neither worked.

The PSA is necessary, as it's clear that TG still has bad batches in circulation. Mine is bought in Nov 2019. If you buy Kryonaut you gamble with the IHS and coldplate.

...one thing has not been mentioned yet. [putsontinfoilhat] Counterfeit product.

Couple of years back we had fake Arctic MX-4 circulating the dealers, it even penetrated some brick and mortar stores... :(

I have some doubts this was counterfeited, doesn't seem to be worth the effort to create this sort of packaging, with spreader and I think even a small leaflet guide inside. My purchase was from Aqua Computer, Germany, together with Conductonaut and a delid tool. The Conductonaut also came in properly packaged and sealed. All products have an invoice too.

How does spreading it (with presumably such little pressure) scratch a metal IHS? It takes some significant pressure to scuff an IHS up like that. Also, similar patterns on are on the IHS, did you (for some reason) apply the product to the base of the heatsink too???? Things aren't adding up. I believe you may have a bad sample, but typically you see pitting or much smaller length scuffing. On the HIS we see long arse scratches going in opposite directions even...

If this is gambling, I will take those odds any day...................thanks for the heads up and all, but I'll continue to take my chances (and win) :). Sorry this happened though. Keep us posted on how they respond. :)
