Arctic Mx-4 or Thermal Grizzly Kryonaut

[SunRise-]

I want to change thermal paste and probably thermal pads for my gpu card Aorus 2080 Ti extreme.What thermal paste is better: Arctic Mx-4 or Thermal Grizzly Kryonaut ?
thanks in advance

TGK is a more performance oriented paste but it's also expensive per gram too.
MX-4 performs very close to it, close enough the extra expense for TGK isn't worth it. Also know TGK is formulated for sub-zero use and works best that way and I don't see you doing that, unless you plan on doing some extreme stuff with the card.

MX-4 will be fine to use with it and it's cheaper too.

MX6 if you don't plan to repaste every 4 weeks.
both kryonaut and MX4 are so thin that they pump out on anything remotely hot.

 

[kiddagoat]

I have used both and I think either one would be fine. I lean towards the MX-4 because it is cheaper.

MX4 is still good, but MX6 is better and will last a long time. It's about the same price too.

Neither. Tm30 is just as good, super cheap, can buy it local.

In the TIM mega thread, it's said there's common ground for testing, so in this theory you could use a drop of mustard, and it would be the same as the rest of the pastes out there.

(Don't use TM30, I am being a smart ass)

Serious note, MX-6.

I've always leaned toward the ones that are slightly more performance oriented.
Yea TGK is $9 for 1gm, but I use it once or twice every few years, not worried about that.

Last paste I used before that was Shin-Etsu X23 and that stayed on a 3770K / H100i for a scary long time (just fine) without a reseat too.

For that kind of money, KingpinExtreme is better.

MX-6 8grams $11

Amazon.com

Kingpin Extreme 10Grams $32

https://www.amazon.com/Kingpin-Cooling-Performance-Thermal-Compound/dp/B07XD3L2TR

IMHO, KPx is the best of the best, but pricey! MX-6 performs very nearly the same(3%-4%) for 1/3rd the price.

You can get larger pack sizes of TGK too, I just didn't need enough to care about the price/gm TBH.
5.55gms is $24.99, 11.1gms is $32.99, and 37gms is $79.99 on Amazon.

i am worry about my temperatures on my Aorus extreme card that's why i want to change thermal paste. In Alan Wake II sometime i hit 80 or even 81 degree with 60% FAN.If i set 80% FAN temp drop to 73-75 degree.I am in dangerous zone of thermal .I mean the card runing fine OK ,without BSOD or throttling,but i m scare with that temperature.In another game title like Alien Dark Descent my card goes to only 51-60 degree,but in Alan Wake II in some area goes to 80-81 degree,and now is winter ,and my case is in very ventilated room with 10 degree ambiental room

All the mentioned pastes will be within 5-10 degrees of each other under these circumstances. Not enough to get a cool running card to overheat with a worse paste, or get an overheating card to run cool with a better paste.
Just pick one that fits into your price range.

Here some different review results from different roundups across the last decade or so:

And 73-75°C isn't anywhere dangerous.
As example, here data from the bios of the ancient 7300 GT in my 2007-era retro rig:

Yes, that is a throttling temp of 115°C and a critical temp of 125°C
My almost as ancient 8800 GT ran 103°C under gaming load and also didn't throttle (but that was much above what I'd consider comfortable)
My (not quite as old) GTX 660 Ti is fine up to 70°C, after which it reduces it's boost, but won't complain until somewhere in the 90's, and that was easy to keep under 70°C with a manual fan curve.

Don't use low viscosity pastes on Direct-Die applications. Arctic MX-4 will suffer from pump out as that was the last used thermal paste by the previous owner of the MSI RX 5700 XT Gaming X I had for a few months.
For GPUs, I would either opt for Honeywell PTM 7950 phase change thermal pad (or the Maxtor branded equivalent), or if you really need to stick to pastes, Thermalright TF8/TFX.
My Nitro+ 5700 XT uses the PTM 7950 for a year now and the Core to Junction temperatures are still low and in idle to medium loads there is only 0-2 degree gap on the core to junction temperatures.
My Colorful RTX 3070 maintains a 10-15 degree Core to Junction Temperatures.
They are used in warm ambient temperatures (34 degrees Celsius) so I am pretty confident in their long term durability.
The screenshot below is from my Nitro+ SE 5700 XT.

SYY-157.. its cheap and awesome.

My temps makes the peoples envious

That doesn't mean it's ideal. Ideal is 64C and below. Between 65C and 70C is acceptable, but not preferred. Above 70C is in the area of temps that some(myself included) consider unacceptable.

From personal experience, if you plan on overclocking or dealing with highly thermal dense silicon (ex. 6900 XT), Kryonaut is better than MX-4. However, with that said, I recently tried MX-6 and very much so like it. The paste itself is very thick and is a decent alternative to Kryonaut.

I would opt for MX-6 if you can find it for cheap.

 

[P4-630]

I use Kryonaut Extreme.

I wonder why they excluded SYY and Honeywell?

I wonder why they excluded SYY and Honeywell?

I guess because the PTM 7950 (if that is the Honeywell product you're referring to) and the SYY-157 are fairly new products in the mainstream market. But in gaming laptop circles, the PTM 7950 and its derivatives are second to none in thermal performance and the longevity to withstand repeated high to low temperature swings that often happens in laptops due to their smaller heatsinks and comparatively less mounting pressure capability on the baseplate assemblies. Those reviews are somewhat old, too. (in comparison to new products introduced to the market).

But for thermal paste, high viscosity characteristics makes the paste resist pump-out effect (although it makes it harder to spread the paste). Pastes like the Shin-Etsu X-23-8079-2 / X-23-7921-5 are excellent in this regard (Like the Thermalright TF8/X). As far as I know, Kryonaut has good performance characteristics (It is meant for LN2 after all) but it suffers accelerated degradation when it experiences temperatures above 80 degrees Celsius.

80 degrees is nice and cool. You do not need to repaste anything.

Hi,
I personally hate gpu noise so I opt for water cooling especially gpu's because they are the most annoying.

Seems the new norm for many newer items for speed they simply raise the acceptable temp/ noise threshold and leave it.
Repasting a gpu isn't as easy as doing a cpu so might as well get the best there is

Arctic is okay but they have had their recent issues with mixtures with just mx-5
So has thermal griz with rocks in the tubes lol
But gpu I'd likely go TG with air.

But then again with your choice of fan rpm I'd change that first and use a fan curve seeing you know the temp range and at 80c they should be closer to 80% and above that 100%

70c try 70% rpm

HONEYWELL PTM7950 / Gelid Solutions HeatPhase Ultra / Arctic MX-6
Use good putty for your graphic card VRAM. The pads the problem is that sometime you need 1.2mm or it doesn’t close the gap enough resulting in some crazy delta.Try the Upsiren UX Pro / U6 Pro or the top of this chart.
