ARCTIC Introduces New MX-5 Thermal Compound

ARCTIC, one of the leading manufacturers of low-noise PC coolers and components, officially launches its MX-5 thermal paste today. The newly developed, high-performance paste comes with an ideal set of thermal properties, guaranteeing reliable heat dissipation over long periods of time. ARCTIC MX-5 is available now in variants ranging from 2 to 50 grams, with and without a spatula.

Like all thermal pastes from ARCTIC, MX-5 is completely metal-free. Because MX-5 is neither conductive nor capacitive, it is particularly safe to use: the possibility of short circuits, corrosion damage or discharges is eliminated.
Regardless of the application method, applying MX-5 is very easy thanks to its low viscosity. The paste can be evenly distributed across the CPU in an extremely thin film via contact pressure from the heat sink. Combined with high thermal conductivity, this results in very low thermal resistance, which can contribute to improved service life and processor performance

MX-5 uses carbon microparticles as a filler to smooth out small imperfections on heatsinks and heatspreaders, improving heat transfer from the component to the heat sink. It is suitable for use on all CPUs and GPUs, whether they are in PCs, laptops or consoles. MX-5 is also recommended for integrated circuits with high waste heat and for power semiconductor devices.

Availability
The MX-5 is available now atAmazon with a starting price of $5.89 USD.

I noticed on the 2g and 8g syringe sizes you can get it with the little blue spatula spreader for $0.10 (a dime) more. Might grab one with it to have for other compounds.

My NH-D15 does the spreading for me :p

Both on MX-4 and NT-H2, only applied a pea sized dot on my Ryzen and what I discovered once I took the CPU out (which, thanks to the fantastic SecuFirm, remounting this thing is a breeze), a perfect, thin spread of TIM on both the cooler and the CPU. Never bothered with any other application method.

But let's not turn this into an age-old tech nerd debate please.

80-watt HamsterYou've got it backward. Viscosity can be notionally thought of as "thickness". Higher viscosity = lower rate of flow.
Oops, you're right I did have it backwards... Deleted.

This. Facts are needed to make an objective decision on the value of this product. Anyone have test results to share?

Chloe PriceMX-4 is already my favourite, so I'll grab a 8g syringe of this on the next time when I buy thermal paste.
You'll buy it and there is not actual useful info in that post ?, OMG Arctic loves people like you.

It's an Arctic Cooling product. Never have they released a TIM that failed to perform very well. This is one of the few times in life were we as buyers can just buy something knowing we have a sure thing.

lexluthermiesterLikely very high. This is a press release. Arctic likely didn't think people would ask for that metric as review sites would likely test it anyway and disclose such after testing.

@W1zzard
If you and the review staff have the time, a comparison of TIMs would make for a very interesting article.
What's "Very high"? Higher than Kyronaut Extreme? doubtful

I just used mx-2 because of it cheap 65G tube. I still use the same tube so far. May not be the best for Artic for maximum cooling but great for high heat application like laptops due to its higher viscosity thus less thermal pump out.

Yup, high heat applications such as laptop and air cooled GPU&CPU definitely need highly viscous TIM.
IMO the best all-round TIM would be the Kingpin KPx, high performance and high viscosity, 30usd for a 10g tube is not insanely expensive either.

Just to add I wish reviews have testing for thermal paste that is set for a few months to test for thermal pump out especially for things like laptops with small heatsinks where temperature go over 80C or more sustained unlike deskstop with a chunky heatsink. On reddit the best performance thermal paste like Thermal grizzly have problem with that. Temperature are great for the the first month but get worse over time.

So ?, and i am sure you can name a bunch of company's that used to sell good stuff but found out it's trash today too. Worlds going crazy for taking another person(s)\Company's word for some thing. I will wait until there is solid proof from many sources before i decide it's actually worth the extra.

Ok, YOU wait for testing results. Everyone else can buy some for the very inexpensive price of $7 and enjoy the results of Arctic's new hotness(or is that coolness?)! Carry on good sir, carry on...

Always handy to have some cheap, MX-4/5 (REVIEW!), and higher end TIM for all the builds I do.

MxPhenom 216You ever try Thermal Grizzly Kryonaut? Its better
I've had 2 bad batches now. One spread like chewing gum and the other scratched up my heatspreader.

I get good results with Noctua NT-HT2 though.

looks nice, but i'm gonna buy it after the 3 tube that i own empty

I also had the scratching bad batch. Scratched both my 2700X and my waterblock:mad::mad::mad:. Most of the scratches can’t be felt with a fingernail, but the biggest one can. I’m worried about my GPU and GPU block, since there’s the same bad batch of Kryonaut there.

Yeah I saw the same stuff about the bad batch - I'm struggling to believe that a single batch has been doing the rounds since at least 2018.

It left my last waterblock in a similar state too.

Since everyone is talking about different thermal pastes, i would like to say NT-H1 is terrible. It does not stay on the CPU. It is like yogurt. It just goes away after 6 months. I bought CM Nano Diamond 6 months ago, still giving the same perfomance and much better than NT-H1. I would like to try Kryonaut but y'all complain about that so, i will move on with this.

By the way what do you recommend me for 5739G laptop fan? I mean oil... That fan is terrible designed! It makes buzzing sound after some months. I change it's fan like year subscription... I will use oil this time but shoud i use low viscosity oil or high viscosity oil? I feel like if i use high viscosity oil, motor will heat up due to heavy oil but if i use low viscosity oil, it won't be longlasting.

There is German YT review of MX-5 and it beats all pastes including Kryonaut

Lmao what? Used NT-H1 religiously before I switched to NT-H2 and it was one of the best pastes I've ever used. That title now belongs to the NT-H2.

Please post a link to it. I'm curious about the test results.
