Thermal Grizzly KryoSheet

[W1zzard]

Thermal Grizzly KryoSheet is an interesting alternative to thermal paste. The pre-cut sheet doesn’t dry out over time and you don’t have to try spreading it in a thin layer. In our review we test thermal performance on the AsRock RX 7900 XTX, at up to 475 W.

Thanks for the review.
I tried for my 7800x3d, really good performance. Switch my watercooling and i messed up. It’s very fragile on the more darker parts... 26€

I wonder if the performance would improve or worsen if you aplied some silicone oil on it, it would help to hold it in place. The excess oil would just squeeze out without problem under the cooler pressure. The oil itself should be pretty inert and should not react with the pad in any way.

I would like to get a sample of this material to play with... It is very convenient that I live close to Germany, they can just send me a letter with this stuff cheaply and quickly...

It is wonderful to see such in depth review for a unique product.

A few questions (maybe already answered, as I didn't read it all):
- Is it better than the original out-from-the-box past that applied in the factory?

- Why not testing it with CPU, as it is a much more common use for DIY past. Not many people take off the GPU cooler to change the past, at least not while under warranty.

I suggest to do another review with high end CPU with and without median-high OC.

Anyway, a wonderful read.

@BoggledBeagle Nah, just Kapton band on the corner so it doesn’t move and be careful with the pump.

For @W1zzard Definitely take a bigger sheet and protect the border with Thermal Grizzly TG Shield ~ Nail Polish type or kapton.

There is a 25x25 size, no need to risk doing cuts. I've posted it in our 7900 Radeon thread last year.

The core idea must be excelled one more time. This thing ain't for records, but stability. It will never pump out. Put it and forget it.

Shame w1z didn't test PTM7958 also.

There are soft tweezers for the task. Also you can hook up thermal shrink tube to any tweezers and make it as a gentle pick up tool. Be creative.

Pro tip is to use a bit larger and put some small thermal paste dots in the substrate corners, so it sticks while you align the heatsink on.

One split will not affect the cooling performance in any way, even if it was in the middle.

What is the value of thermal conductivity ?

 

[Sasqui]

Very interesting product. I still have half a 5 gram tube of AS 5... maybe I should get with the times?

Hi,
If it's like a fabric then it doesn't have any sticky properties to either side ?
If not anything it's applied to has to be horizontal so gravity doesn't let it drop before applying a cpu cooler ?
Gpu would be a piece of cake to apply or if you can lay your case on it's back.

But if vertical and back mounted cooler or server this wouldn't be so easy to use unless you added a dab of thermal paste/.. to hold it in place.

It is slippery...

Thermal paste are tiny solid pieces of something that conducts heat well suspended in come carrier material. You do not want that in this product, but the silicone oil I mentioned earlier has no solid stuff in it and should make the pad stick to the surface well.

Best to use on high performance laptop where TIM pump out is commonplace.

 

[Panther_Seraphin]

Looks to be an ideal material for laptops/consoles

I have been using this on my 4090 for 6 months with amazing results -- the PTM Sheet that came OEM developed a bald spot and i had a 30C delta on hotspot vs core with fans at max ramp, now I can't hear it anymore while gaming.

Also use this on my air cooled 13700KF and it works awesome. Never buying paste again for builds.

 

[Onasi]

Honestly seems like more of a hassle to apply than paste. Maybe it’s just me being used to it. An interesting option for those cases where pump out is a legit concern, though. So mostly really high end GPUs and laptops. I don’t think that sub-250 Watt GPUs will benefit much, or most modern CPUs for that matter, aside from recent i9 models maybe? Someone can correct me on that.

 

[remekra]

The upside of this is no pump out issues. Had 7900XTX from Gigabyte and slowly after few months temps have risen to over 100 because of pump out, even though at first it was only at 87.
Many users can be found with the same issue, this and PTM fixes that. Although it should not be a problem in the first place.

@W1zzard You were hungry when you typed this out, huh?

 

[lexluthermiester]

In our review we test thermal performance on the AsRock RX 7900 XTX, at up to 475 W.

That is a fairly brutal test for any TIM. Glad you reviewed this! The cautions are worthy of a moment's pause, but the performance is excellent!

Would love to see a PTM7950 comparison as well.

All cool to work with water blocks? Thanks.

@W1zzard nice review, would be very helperfull if you can update it with PTM7958 & LM at the end when it the only one that left for test.

Anothers review with a @ 14900K & 7950X would be amazing too like a part #2. Testing with a watercooling setup on CPU and pushing high load, for see how the sheet is good versus like KPX paste and LM

 

[Easy Rhino]

certainly easier to clean than thermal paste...

 

[damric]

I bought a two-pack of these from another brand last year (ID Cooling maybe?). I only recently started using them for my very low cost hardware benching because I got sick of wasting so much thermal grease when changing out parts. My results have been mixed, but good enough to keep using them for that purpose. The latest bench was an old Phenom II 925 cranked to 4400MHz at 1.625v. With room temperature water it peaked around 46C. https://hwbot.org/submission/5446140_damric_cinebench___r15_phenom_ii_x4_925_442_cb
