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

Kingpin KPX is really impressive stuff in outright performance, I used it on the die of my delidded 4770K and get great temperatures. The problem is that outside the U.S. it's so hard to find and usually overpriced (although still nowhere near the huge prices of Thermal Grizzly). Arctic MX-5 sacrifices a couple degrees in comparison but it's a fraction of the cost and has a long application life, so ultimately I find it's the best all-rounder for the majority of build scenarios.
 
Perhaps MX-5, the subject of this thread. Been using it in both of my laptops and it works perfectly. KPX is also an excellent TIM.


This is a good one too!
Respected Sir, I don't have much knowledge about these thermal pastes but I want a paste for my laptop which can lower temps considerably and has remarkable longevity in terms of not drying out etc. and not having to repaste it that frequently! Thanks.

Out of these which one should I go for: MX-5, KPx, SYY-157, TFX or any other? Thank you.

Thermalright TFX.

Interesting tests. Now look up prices. TFX is at the top of that list, but it's also very pricey and there are no guarantees you're going to get the same performance shown in that system on your laptop.

Also, as I've said before, the TIM is only one part of the equation. If the cooling solution is not up to the task being asked of it, the heatsink compound won't help much no matter how good it is.
 
imo cheapest cooling warrants cheapest paste, whereas a good loop might benefit from the best paste. Or could that work the opposite way around?

Please can you explain what you mean by cooling solution is not up to the task..how can I check it on my laptop?

Sure. What I mean by that is if the cooling system in your laptop is of limited thermal capacity, the heatsink compound you use will be of little consequence as long as you use a good one. If the laptop was/is already struggling to keep the system cool, it will continue to do so regardless. Put another way, a quality heatsink compound can not cure the limitations of a poorly designed cooling solution.

No TIM, regardless of brand or type, can be a miracle solution if a subject heatsink and fan can not extract heat from the system in question very effectively..

You can use the best thermal compound in the universe, and it wont matter if the heatsink isn't big enough with enough ventilation
Many laptops are designed for 'average use' and the cooling is garbage under heavy load
 
What matters a lot with laptops is how long the thermal paste stays intact for, as well

I'm not sure if you were part of that conversation earlier in the thread or not
 
So being that this is a copy pasted reddit post from 4 months ago...
What are the long term results?

I asked the OP yesterday about it! He says the results are the same as day 1. No sign of degradation. He even has a youtube channel where he is testing it. https://www.youtube.com/channel/UC6pf0tLLBFPkBYJigLt3s3Q

Rofa1234 (Rooter1234) talks about it and shared some articles.

More people reviewed the same TIM (4 months old)

Hi,
After sending out bad batches on release does anyone really care about mx5 alien baby shit anymore :laugh:

To be fair, the #1 priority on laptops is to get the heatsink properly balanced and with firm, even contact pressure. Tripod heatsinks are the worst.
IF you have proper Conductive Balls of Doom protection (thin soft (low PPI) polyurethane foam dams + Kapton tape (or nitrocellulose based nail polish on substrate contacts) on BGA throttlebooks, Keaded Eraser (Great stuff) around the socket on the rare LGAbooks, and you did some work to balance or fix the mounting pressure (spring clip mods, removing C-clips, washer mods, even very carefully sanding the heatsink base flat, with the very careful "less is more" as you have very little leeway on this), then Liquid Metal is always going to be the best option.
Even if the MAX temps remain "close" to the same as on high end paste, the important thing is the time to reach 'steady state' (max temps) increases substantially on liquid metal, because more heat is pulled off the chip, and the heatsink slowly gets heat soaked so the chip stays cooler longer. This is a good thing for laptops with TAU/turbo boost power limit settings, where higher loads can only be maintained for short times, then liquid metal would keep the temps down for you. Even for max temps, LM vs Kryonaut/MX5/SYY-157 can still be a 10C difference.

But LM requires mature, responsible people using it.
 
I have to say I used some Kryonaut for my recent pc build and it came out much dryer then I am used to with Arctic (I think I had mx2) which was a tad concerning.
Its a good thing that arctic remains ermm fluid and all unneeded access is squished out if you apply enough pressure, that is why "too much" thermalpaste isnt really a thing.

Anywho, yeah idk, I am thinking of getting some MX4 or 5 myself to replace the Kryonaut, though I dont think its preforming poorly as is.
I went back to Artic MX4 because in my case the temp changes were negligible for such the cost difference for the amount you get.

To put it bluntly Kyronaut was a expensive joke. I was not impressed in what you get. I've already posted how cool my computer is running these days. I am using Artic MX-4 on my current rig.
 
It seems that arctic mx-5 discontinued.
