[EOL] Arctic MX-5 is here!!Tests incoming! Completed. Now its MX-6 testing time!

[phanbuey]

The regular Kryonaut I used from 2018 till 2022 (upgrades).

I'd buy Kryonaut Extreme pink bubblegum (long term durability)

Thermal Grizzly Kryonaut Extreme Thermal Paste

Kryonaut Extreme is a high-performance Thermal Paste with optimized low-temperature load capacity for extreme overclocking.

www.thermal-grizzly.com

If you don't care much about a posssible few degrees higher running CPU you could still use Arctic Silver 5, it's really long lasting stuff, used it on my dads PC back in 2010, still runs today, now almost 2023.....

So I used the pink Kryonaut extreme on my gpu and it definitely is better long term than the mx5 and the regular Kryonaut (much better than regular Kryonaut) - lasted about 6 months before fan started getting annoyingly loud again and temps creeping up.

Ran really well on the cpu though - no pump out or temp difference vs fresh paste on the 12600k after 6 months and was still nice and gooey when I took off the aio even in areas where it was thin.

I think the msi Ventus cooler design is just not that great at keeping paste - the original reason for repasting was that the card got much louder as it aged and ram temps were out of control due to inferior thermal pads - that oem paste was basically dry clay on the gpu when I opened it up.

hmmmm

So if I go to a 5600 cpu what paste would last me at least 6 years then?

Another vote for AS5.

Another vote for AS5.

I asked Arctic for a tester of AS5 and got told it was EoL. I've got MX2 and MX4, wanted MX5 for the collection lol.

MX-2, AS5, Ceramiqué 2, MX-4.
Ceramiqué 2 is the absolute thickest paste I've used, if you only care about pump-out, but performance is mediocre.
If longevity and consistency is all you care about, grab some Shin-Etsu or Dow Corning.

MX-5 and Arctic Silver 5 are different products, made by different companies. AS5 is definitely available.

My MX-6 just arrived, it had a rather neat security feature on the box, an authenticity check QR code, but half of it was like a scratch off lottery ticket, it makes you scratch it off then scan to check for authenticity, and it says if this is fully visible do not use (I think, I just threw away the box).

fascinating, never seen that hardcore level of security even for my expensive headphones, let alone some cheap paste. kind of a nice touch though, well done Arctic.

very few

Longest shelf life are the waxy types OEM use, MX4 has a long shelf life and might stay stable that long - assuming you have a solid contact and the cooler never gets jostled around breaking the seal

thats one thing i really like about the reference design rx 6000 gpu's and the playstation 5. the gpu's use graphite that never needs replaced (as long as you never open it and break the seal) and the ps5 uses liquid metal which should never need replaced either.

i think this is a good way to do things really.

I think there is mx-2 on there now. But ya, case never gets moved, just sits there.

I don't mind re-pasting every 3yrs +, but I would not want to do it every year. How long does MX-4 last for? I think I have a new tube of that.

hmmmm or MX-6?
"Each application can stay in place for 8 years (maintain conductivity and viscosity)."

 

[ThrashZone]

Hi,
Goodie more hype on a less than 20.us item

 

[MachineLearning]

I think the units are off for MX-6 viscosity on Arctic's site & spec sheet.

MX-6, pretty sure that is supposed to be centipoise (cP) or 450 poise.

MX-4:

MX-5:

Also interesting, the specs they choose to include and their order has changed over time. And thermal conductivity ratings are gone - they were interesting to compare between Arctic pastes.

Thermal Grizzly sell reusable graphite "pads" for cpu/gpu usage. So it is possible to go that route

colour blue? i wonder if that is referring to the outside of the mx-6 tube, that is blue. but the paste itself, color is silver/gray on my end. I know I got a legit tube, it was shipped by amazon and sold by Arctic. hmmm.

oh wait. the other two say gray... the last one says blue. and now i just figured out what you are talking about lol... its not matching up.

hmm odd. I have no idea on that. I am pretty sure my tube is legit mx-6 though.

I have tried a graphite pad a couple years ago, and I got 3-5 celsius worse than paste. probably doesn't matter to most people, but I want my CPU to stay as cold as I can get it. hence this thread really, just fun hobby to try and find the best paste. at end of day though, it doesn't matter.

the only tests i am going to do this time are nt-h2 vs nt-h1 vs mx-6. those are only 3 pastes I will be testing this run. i think i am done messing around with pastes and temps after this run. just getting kind of tired of it.

The blue paste is the mx-5. Its purdy

I know mx-5 is blue. I think I am just confused here. Nevermind, I am tired... and on that note, gnite actually lol

So my tube of MX-6 arrived. Testing will begin in a few days(busy currently IRL).

@maxfly
How about you?

Curious about viscosity. MX5 had more of a sticky-ness to it. MX4 was easier to spread

I will give details of what is observed.

MX5 had more of a sticky-ness to it.

I didn't have that experience. It was a bit gooey, but I wouldn't call it "sticky". Still, did a great job.

MX4 was easier to spread

True, MX-4 is easy to work with.

Mine came last Saturday not quite as pristine as yours thanks to the giant bubble envelope it was shipped in (box is torn up)but the tube itself is gtg. Things are looking good for this weekend! Altho, I'm going to go with the noctua u12a for testing. It's just faster to pop on and off vs the assassin.

Sounds good! I'm aiming for Saturday to do the testing and will post results Sunday.

Just to be clear we're doing Prime95 with Small FFT mode and Cinebench R15 Extreme, yes?

Yep, that's what I've got on the schedule

 

[Space Lynx]

There are some initial results on another website I was reading about that say its about 3-5 celsius better than MX-4. So I am very curious to check back in here Sunday and see results from you two.

Why do I feel like MX-6 is just MX-5 rebranded?

 

[Count von Schwalbe]

Why do I feel like MX-6 is just MX-5 rebranded?

Pretty quick to develop an all-new formulation! Probably just tweaked for more stable production and a rebrand if I had to guess.

 

[lexluthermiester]

Why do I feel like MX-6 is just MX-5 rebranded?

It's not. For starters, it's grey not blue. I'll detail more in my review this weekend.
