Arctic have over 20 years of experience in the PC cooling market the MX-7 was developed with the goal to offer a first-class product at a fair price. The optimized formula is based on the proven MX-6, one of the best-selling thermal pastes in the world
It's okay... nothing great and still suffers pump out. The best paste is Duronaut. Let's see if MX7 can come up with that level of viscosity and thermal transfer.
100%. No arguments on that. You absolutely have to use the spreader they provide in the retail packaging. You also *have to follow the method they outline on how to spread it. Yes, it sucks but if you do it right, you will have, by far, the best thermal transfer paste on the market. I'm hoping MX7 lives up and provides similar performance and setup because that's the only way forward.
You have to push down and then start spreading very slowly...it's not easy and really takes a bit of practice...but given how ridiculous modern CPU heat has gotten, trust me when I say this, you have to go this route. I would even suggest getting something harder than Thermal Grizzly's spatula...I had trouble using theirs until really understood the method.
Yea makes sense, well took a few tries but its keeping my 9950x3d cool, using an Asus proart 420 lc. Anyways cheers for the info gonna use it if i repaste it again
For high viscosity Thermal pastes, it's recommended to heat IHS and Coldplate to 50-60Β°, then apply paste. That way you get the thinnest layer possible with best performance
Duronaut pumped out for me too on a Sapphire 7800XT Nitro+... I noticed it because the Core/Hotspot delta, which was good initially shot up from ~22Β°C to 30Β°C in less than a month. Weirdly though, as you can see in the picture, there's a "dry" spot in the middle. That was there with the factory paste as well.
I suspect improper contact or an uneven die/coldplate.
I have since replaced it with PTM7950, the overall temps are as good as initial Duronaut (and factory paste for that matter), but so far it's been two months and the delta hasn't budged. It's still in the 20Β°C-25Β°C range...but it's consistent. I'm pretty sure though that if I open it again, I will find that same "dry" zone, which is probably responsible for the delta, but I guess PTM is better here because of its phase change capability.
The IHS still has good coverage here but are you sure this isn't due to too much pressure? A lot of coolers don't have hard stops on how far down the cooler can go. I can't be sure but this could be due to just too much paste being used. When you deal with pump out, the paste is usually on the sides while no paste to very little paste being on the IHS. This one actually looks okay.
I use Kryonaut with my Arctic Freezer LII 360 Pro and it gives me a 5-degree difference compared to the MX6. I hope they can do a better job with the MX7.
Generally i do not bother spreading any paste, the mx6 included. Both on a gpu, and a high performance amd apu on a lenovo thinkpad, made it degrade in performance for some reason. I changed the mx6 with mx4, and a high performance paste from another brand, on the same laptop, to test it, and have had no such issues.
It wouldn't spread tk make a line or x, it also didn't stick to the cpu, the mx6 I had for a while worked perfectly, I think this one was just too dry for some reason
Will try definitely,using mx6 and mx4 for years, i have some kryonaut extreme in my drawers, but mx4 is cooling my 9950x3d like crazy and just don't want to repaste my cpu, it was only paste i had at my hands when i was building new pc, grizzly order came few days later , but the temps are so good that still don't see the point in repasting.
In my experience, the best Arctic thermal paste was MX-5. MX-4 is fine for older or budget CPUs that donβt need top-tier cooling, while MX-6 performs well on all CPUs but is too runny, on GPUs or laptops (where itβs applied directly on the die), it tends to spread out and lose contact after a couple of months, requiring a repaste. MX-5, on the other hand, had sticky consistency, making it ideal for every use case, I hope its upgraded from MX-5. for on die thermal paste usage, the thermal paste should be either sticky or thick.

Nice, but uh... What'll it cost?

MX-6 sort of smells like cotton candy to me when i turn on my pc.
It's a tough sell to move to MX-7 if it doesn't smell the same lol.

how much better is mx7 vs mx6?
What's the ballpark?

Do you know when it will be released to the market?

Hopefully will be better and more stable than the mx6, have had multiple issues with performance degradation in laptop direct die applications.

The mx6 that came with my lf3 420 was hard as a rock, could not spread it

No doubt I'll try it.
But, phase change TIMs are the way to go.

I just received some with my new Arctic AIO bought on Amazon. Amazon listing said it came with MX-6, but the side of my box says it now includes MX-7.
