Another Thermal Grizzly Kryosheet Experience

Similar to @SpyderTracks thread Here I had picked up the kryosheet for my laptop a while back. It ended up getting lost so I did a repaste with conventional MX-4 and waited on the replacement. When it came, I had never bothered to change it as it was working OK. My plan for the laptop is to use it for an arcade cabinet down the line so just wanted normal temps.

After looking at the thread I thought I would give it a go to see what the experience was like. I've gone through liquid metal and standard paste, more so because the liquid metal is corrosive. I've never had particularly great results with pastes outside of the LM so it definitely works as it should.

Prior to doing anything I left the system for 15 minutes or so and then checked the min idle temps.

I did a run in Prime95 small FFTs before the sheet went on. This is relatively fresh paste with it only being a week old. I had similar experience with other pastes, with the LM being the exception.

This really wasn't surprising to me as small FFTs is a proper torture test. The closest I got to this in a gaming scenario was GTA5, which for some reason saw low 90s and crushed my CPU temps.

I let everything cool and then I ran a quick Firestrike test to see where it landed.
CPU temp 91c, avg CPU frequency just over 4.1 while set to 4.5 (4ghz Stock)


So, I switched out the paste after a good clean with alcohol. Note, my CPU is de-lidded so I added the sheet on top of the die as well as on top of the heatsink. I did the same with the GPU die, all cut to size as accurately as I could. I'll be honest, the stuff was great to work with. It requires finesse but it wasn't as flimsy as I was expecting it to be.

I was surprised to find my low idle temps a bit higher than before. The minimum is probably more reflective here but it did tend to hover 3-5 degrees more at idle than the paste. This had me a tiny bit concerned.

So then it was onto the torture test, once again small FFTs expecting some sort of melt down.

Never in a month of Sundays did I expect that. If the liquid metal beat that (I can't remember) it was by no more than 1 or 2 degrees. I can't remember having such a low result after 10 minutes. The LM hardly lasted a year before eating and degrading the cooling efficiency so this is a game changer for any laptop as far as I'm concerned.

Lastly, back to firestrike for a run. One of the highest runs I've had in recent years.
CPU temp 78, frequency almost 4.3ghz

Hilariously the GPU score actually tanked. Through all the years of tuning this laptop I've always found there's a fine line to balance between giving the CPU headroom and keeping the GPU fed with current (it's split between the 2 mouths to feed). There was so much extra headroom and potential from the CPU now that there wasn't enough power to keep the GPU going at full chat so it had to pull back. I can play swings and roundabouts by lowering the CPU and getting a GPU increase, but there wasn't much point really.

So yeah.... colour me impressed. If the longevity is anything like reported this is a winner for every laptop I have from now on.

PS.... I bought a big sheet so that I could cut it and use it for all 3 applications. This worked a treat and there isn't a lot of saving going for the one cut to size. If you're confident to cut the size you need you could get a few CPUs/GPUs out of one sheet.

That is really good 👍

I got the predecessor, the carbonaut on my old laptop, think I fitted it in 2019 and was still on there when I handed it down. Temps didn’t change the whole time.

I'm really impressed. Normally there's a lot of hype with this sort of product but it's all positives as far as I can see.

Sure, it's not quite the peaks of LM but it smashes it out the park with every other metric. Application couldn't be easier and the fact that you should get a lifetime out of it is just win win. No thermal paste I have tried has performed like that in the small FFT torture test with this laptop. I didn't think those temps were possible in honesty.

just to ask, with the kryosheet, in pcs laptops with gpu and cpu, do you put the kryosheet on just the cpu and paste on the gpu or can you put both on the cpu and gpu, just asking for future reference.

You can put it on both, just make sure you get enough to do both, I only got a bit for the CPU on my laptop, so had to paste the GPU, but when I service it next I'll get a bit that will do both

seems no downside to the kryosheet which is good for laptops

For laptops IMHO it's an absolute essential because of the frequency they need repasting with normal paste, that's aside from just how much more effective it is at transferring heat than standard paste.

For the price as well, say around £18 for a sheet, that's one application and done. If you're settling for paste, say 4 pastes over a 5 year period at £9 per application for a decent premium paste, that's £36 for lesser performance.

On a desktop, one good paste job should see you through for the lifetime of the build, and because of that I was thinking it's not really worth it (coming from my carbonaut experience), but I just didn't expect the heat transfer performance to be quite as good as it is, and for that reason it still makes it well worth it on a desktop.

For anyone on the hunt for one, I initially looked at Amazon, but there's only an EU seller on there I believe, so price wise it's around £20 but that includes shipping, but will take around a week delivery.

If you want it quick, Overclockers stock it for next day.

Yeah, that was why I went for it. I knew it would cover everything I needed. I didn't actually expect to have another heatsinks worth though :ROFLMAO:

If anyone is unsure of the size required (as information can be confusing) the Thermal Grizzly site includes in the description what cpus that size covers, just change the size and the description will include the cpus supported. 33 x 33 is for AM5

This was the one I bought:


50x50, enough for the CPU Die, CPU Heatsink and the GPU no sweat, I could easily do another CPU with what I have left as well. £26.90 delivered.
yeah i was wondering that option as well, from overclockers with next day dpd delivery it works out at about £30

Yeah, it's definitely a premium, but if you need it fast, it's worth it.
Oh yes most definitely, this isn't bad if you can wait a couple of days

glad they got a size guide (y)
