Thermal Grizzly KryoSheet

[Massdeth]

It's fun to speculate either way, but until someone actually does it, a few times, and properly records the data we truly cant know. Although, if its a dismal result on the first try, there would be no need to go further.

I was never about to find out how it performs because the fabric litteraly fell apart during cutting. It's very fragile. It looks like many linen fibers combined into fabric with some gray grease and pressed into material.
I followed the instruction, used sharp scissors and was very careful. I don't know, perhaps my piece was old, faulty or something but in the end I was left with few shreads of the fabric I couldn't do anything with. Expensive and tricky to play I would say.

Hi,
Hope you took pictures to send to thermal grizzly.

Guess they sent W1z a cherry picked sample.

No, I don't think they did. There have been a few reviews on YouTube that showed that the pad needs careful handling but is mostly durable.

Hi,
Well personally I love all the hype thermal stuff produces as far as youtube goes you can keep that stuff to

I may be going blind, but did not read anywhere how the tester controlled the fanspeed on the cooler ?
Maybe it was locked in the drivers ? And was it at 100% or what ?
Would be nice to know, since if the fan speed was on auto, there is a chance the temperatures would reflect the fan speed more than the tim used.
Testing with fans on auto, would be not what i expect of TechPowerup of course, but i just have to ask.
I can run my 3080 with liquid metal at 60 degrees with 350 watts on 100% fan speed,
while on auto fan i get 68% fans and 72 degrees on a cold day, but a quiet room.

And?

It was default. The testing would be invalid if different setting were used with different TIM's.

By default you mean "fans locked at 100% for all tests" - then that is what i am looking for - thx
It sure is an impressive cooler on that card, for a 475watt load.

I saved the scraps for later thinking "perhaps one day I'll find some use for them". Sending photos to TG was never a case since I don't think they would care. As with most of the DIY modifications we take some risk and so it was this time. Long story short: I failed cause I didn't expect it to be SO fragile.

There have been a few reviews on YouTube that showed that the pad needs careful handling but is mostly durable.

I don't know what streams show and what they claim - I was holding that sheet in my hands. You can trust me: it was FAR from durable.
As soon as you remove the transparent plastic cover it litteraly melts in hand (it's greasy). Perhaps cooling it down a bit would help?
So, again: Extreme caution recommended!

Are you sure you bought a genuine product?

Well, yes. It came from an official supplier of TG products in my country. That vendor is mentioned on TG home page among others.

Edit: a picture of what has left and the look at the fabric structure

P.S. I saw one patent of CNT (carbon nano tubes) in which LM (liquid metal) was added inside to boost thermal transfer. Don't try this, they are professionals.

There were some wild ideas for TSV made of CNT and other in-chip extravaganza. I wonder when will mainstream market see those?

Hi,
Need an image of those spoons oops I mean scissors you used hehe

"Spoons", you say? No problem, there you go:

It's a tailor model, we keep it for fabric use only; it never cuts paper, plastics or other material that would blunt it. It's sharp.

For cutting pads I use razor blades or xacto knives rather than scissors. I find that scissors have a tendency to squish things.

I had no previous experience with cutting pads thats why I followed manual to the letter:

So quoting after the manual: "If necessary, scissors are sufficient to cut the pads to size".

 

[BoggledBeagle]

If you first put the sheet on a hard flat surface, then firmly hold it with a ruler and cut it with a fresh razor or other blade, I think it should have no chance to get damaged.

BTW those pieces you pictured look perfectly usable to me, when cooling a chip with a heatspreader on it I would not hesitate to use any combination of these pieces, and even some gaps between them would not affect the performance in a serious way. Gaps for direct die cooling are not good.

They sent me 4 packages, all sealed, looking exactly the same. I seriously doubt they were cherry picked.

I would definitely not use a knife to cut the KryoSheet, maybe along the grain could work, but across, you will probably rip it (havent tested)

Hi,
I was just going off this post
Maybe you two should compare batch numbers or something ?

Talking about batches and product quality, it would be interesting to learn how this stuff is made, who makes it and what are the quality control steps and procedures.

Do they make everything in house with a lot of opportunities for quality control?
Or they let somebody else make the blocks or larger sheets of the material and then they cut it in pieces, and inspect it afterward?
Or they let somebody else do all the stuff including quality control and packaging and they just resell it?

This is the only number that was on the package:

@W1zzard - out of curiosity, are there any plans to test other TIM pads? For instance:

Soft PGS. Essentially compressed graphite sheets, so very similar to the Thermal Grizzly product tested here. Panasonic make EYG-R series of pads, and 12x12 cm sheet cost the same as TG kryosheet pad, making it much cheaper per cm2 (provided it performs the same, that is).

Indium foil. Quite a few companies sell pure foil at e.g. 0.2 or 0.3 mm thickness, which theoretically should be much better interface, albeit quite a bit more expensive. It is conductive, but so are the graphite pads.

There are even fancier variants of indium based pads, such as this one:

But no idea if it's any better than just simple foil

Would be really interesting to compare, especially when next gen CPUs and GPUs are expected to be even hotter...

 

[W1zzard]

who makes it

swedish company mentioned in the conclusion

Oh, thank you, it helps sometimes to actually READ the review...

GF series overview - Smart High Tech

Seeing that these sheets can be ordered with different properties and thicknesses, I believe that for well prepared surfaces (lapped and really flat) these sheets could be supplied thinner, improving heat conduction!

The sheets currently sold by Thermal Grizzly seem to be universal thick ones , but people who know what are they doing should be able to buy a thinner version.

( 0.2 mm is a thickness of two normal office paper sheets. It is thick. )

My reference 7900XT+Alphacool waterblock pumped out like crazy… went from 22ºC delta to 30º delta in not even 3 months. And that’s an XT, so a good 150+w less than this XTX test!
With the Kryosheet (25x25mm, and with electrical tape around the dies), it’s rock solid 13º delta at full load and 16-17º delta at low load since the day I installed it. Best 30€ ever spent on cooling IMHO. Can’t recommend it enough.

Is it possible to set up a simulated pre-mature aging test, or 1 month, 2 month, 3 month, etc baking in period?

Asking because I've never repasted a CPU/GPU, as once set, I will likely never see the CPU heatspreader ever again (last build was a 6600K/RX580->12700KF/3090). I can read on many sites about drying out of the paste, but is there a consistent timeframe when it happens?

I hate to sound like another random internet person, but I'm honestly not seeing a difference in temperatures (as mentioned, likely within the measurement of uncertainty), and while $20-30 is practically trivial when spending money on higher end gaming PC, I also got my vial of Arctic MX5 with my Arctic AIO and so 'free' is 'free', but say after 2 simulated years, the pad got a 5-10 C difference vs paste, I would stand up and notice.
