Thermal Grizzly, a high-performance cooling solutions provider, introduces new size of KryoSheet for the specific adaptation of GeForce RTX 5090 graphics cards to a water cooling solution. KryoSheet graphene thermal pads are an excellent alternative for thermal pastes and have a conformable surface with very high thermal conductivity. The KryoSheet in the size of 44 × 37 mm comes with a Kapton Insulation Sheet.

The new size makes it suitable as a replacement for thermal paste on air-cooled RTX 5090 graphics cards, as the size of the GPU chip can lead to an acceleration of the pump-out effect. The KryoSheet, with dimensions of 44 × 37 mm, fully covers the GB202-300-A1 GPU of the NVIDIA GeForce RTX 5090 and slightly extends beyond the chip's edges. This makes it necessary to electrically insulate the surrounding electronic components. For this purpose, the new size comes with the TG Kapton Insulation Sheet.



The following images demonstrate how to use it on a graphics card, using an ASUS GeForce RTX 5090 Astral as an example. First, the graphics chip and the surrounding area must be thoroughly cleaned and degreased (e.g., with isopropanol). After cleaning, the Kapton Insulation Sheet is applied. The Kapton strips should be aligned along the edges of the chip and carefully adhered. The Kapton strips must not be placed on top of the graphics chip!

Once all four sides next to the chip have been covered, the KryoSheet can be applied according to the instructions (steps 3 and 4). If the adhesive side of the Kapton Insulation Sheet has come into contact with the chip during application, it is recommended to clean the chip again before proceeding. Cutting the KryoSheet to size is not necessary.

Availability and Pricing
Thermal Grizzly KryoSheet products are now available for order directly from the Thermal Grizzly Online Shop or through our Global Network of Distribution Partners.

Manufacturer's suggested retail prices (MSRP) including VAT: €22,90

Hmmmm. Didnt I read on another news thread that certain AIBs were using LM?

Seems a little funny taking apart a 5090 just so you can replace the LM with a kryosheet

Meeeeh. I would go for some sort of PTM solution for this sort of usage, but fair play to them for releasing something hassle-free I guess.

looks pretty jank, would have preferred it if they included a single cut to size "Sticker"

as it said, its for people replacing the standard cooler for a watercooling block, you have to apply new "paste" anyway and liquid metal might be a hassle or even not really possible with the new waterblock.

I think that only FE is cooled with LM. Although, it would be interesting to know if there is any difference after swapping those two. And.. if it doesn't void the FE warranty.

I really might try these for my laptop... they seem like a great solution and I feel like PTM 7950 is a little over hyped....it will eventually pump out over time and does degrade in performance... I'm seeing 90C on my CPU when previously I was barely hitting 80C a year later.... Literally an impossible chance of pump out...and can withstand the constant shuffling of moving a laptop

Let me get this straight: the OEM TIM ain't broken so it got "fixed"?

Moving past the attention seeking part of it, there is a joke in there somewhere.

Surprised it ain't marketed for x-oc , but air-cooling.

This is so much better than thermal paste it's actually crazy.

If more people were comfortable using this there would be no need for thermalpaste.

the damned article said:

*smh*

Assuming I ever get my hands on a 5090, I will probably go this route when 'blocking it for my custom loop. I've always done liquid metal in the past, but the tests I've seen these sheets are nearly as good.
