Arctic MX-4 vs Noctua NT-H1

Somewhen, the pre-applied thermal grease in our processors and GPUs will wear or dry out. You will notice an increment in your system temperature if this has happened already. If you are non constantly monitoring the temperatures as enthusiasts exercise, you volition detect this out when your calculator suddenly turns off. In other cases, your PC will fry out and die altogether.

If y’all want this non to happen, it is best if yous invest in a loftier-quality thermal paste. Non only does it assistance protect your devices, but it also boosts their operation. Fortunately for yous today, we are comparing two thermal pastes from known thermal solutions companies. Nosotros are going to put the ARCTIC MX-4 and the Noctua NT-H1 head-to-head in a comparing. Let’s find out which is better, shall nosotros?

Chill MX-four vs Noctua NT-H1 – Similarities

Let’southward review the specifics in a next chart.

Not Electrically Conductive

The only similarity I tin see betwixt them is their conductivity or lack thereof. Both the ARCTIC MX-4 and Noctua NT-H1 are composed of materials that are non electrically conductive. Therefore, you can residuum easier applying either knowing that they will not impose risks on your figurer. Aside from this and their roughly identical density, everything nearly the MX-4 and NT-H1 are different.

Arctic MX-4 vs Noctua NT-H1 – Differences

Material and Composition

Thermal paste comparison ARCTIC MX-4 vs Noctua NT-H1

The fabric and mixture of a thermal paste is important because it dictates its cooling backdrop.

Arctic MX-four

The Arctic MX-four uses carbon microparticles as a medium to transfer estrus from the processor to the heatsink; thus, information technology has a high thermal conductivity. Unlike other thermal pastes such as liquid metallic, the MX-4 is metal-gratis and not electrically conductive. Therefore, information technology does not impose the take chances of shorting out your organization.

Noctua NT-H1

Noctua did not provide on its website what the NT-H1 is made of. With some excavation and a niggling research, I constitute out that the NT-H1 is a synthetic oil mixture in its rubber sheet. Information technology’s unusual for a manufacturer to leave this information out. All that nosotros know well-nigh the NT-H1 is that it is non electrically conductive. With that said, it’s a necktie for now.

Thermal Functioning

Difference between ARCTIC MX-4 and Noctua NT-H1

This is the category that all has been waiting for. The thermal performance of a thermal paste is its most important attribute. Permit’due south see how both perform.


The thermal performance of a chemical compound is nearly oft not stated by the manufacturer, rather they let the professional benchmarks exercise the talking for them. With that said, the Arctic MX-4 performs quite nicely at 36.9 degrees Celsius for an air-cooled CPU. Moreover, on the GPU side of things, it produces an average temperature of 67.5 degrees Celsius. These temperatures can exist considered impressive since it is among ane of the bests.

Noctua NT-H1

Although we do not know what the NT-H1 is made of, we exercise know its performance. Noctua refuses to evidence its thermal electrical conductivity, stating that this specification does not guarantee existent-life performance. Moreover, they included that many other factors may bear on this number that other manufacturers may manipulate to make their products more than compelling to buy. In terms of NT-H1’s performance, it is inferior compared with the MX-4. Its temperatures are 37.ane degrees Celsius for an air-cooled CPU and 68 degrees Celsius for an air-cooled GPU, co-ordinate to benchmarks. Although it is marginally worse than the MX-4, it is a relatively swell performance considering information technology is cheaper. If y’all are targeting the best thermal functioning, go for the ARCTIC MX-4.

The Winner Is- Chill MX-4

Non regularly replacing the thermal compound in your computer is user-friendly. You don’t accept to open up your computer cases that ofttimes. Let’s see how long these thermal pastes last.


Thermal pastes should not be reapplied more than than in one case every few years, at least that’s what Intel is telling us. Enthusiasts recommend replacing it once every year, all the same. To add to its superior thermal performance, the ARCTIC MX-iv has better longevity, too. ARCTIC promises that the MX-four tin can last up to 8 years without getting dried up. This is impressive to achieve because most people will have new PCs past so. The ARCTIC MX-iv is available in many size variants: ii / 4 / 8 / 20 / 45 grams.

Noctua NT-H1

Noctua NT-H1 is a high-quality thermal paste that can last more than than v years. Y’all tin can shop it for upward to 3 years, according to Noctua. This paste besides has no break-in or burn-in period, unlike most thermal compounds. Therefore, the NT-H1 is ready-to-become out of the packaging and does not crave any special preparations. The Noctua NT-H1 is available in 3.v grams which tin can be used from 3 to 20 applications depending on the size of the processor.

The Winner Is- ARCTIC MX-4

Pros and Cons

Finally, some pros and cons of the thermal paste ARCTIC MX-iv and Noctua NT-H1 will help united states of america determine which is the best pick.


ARCTIC MX-4 Heat Sink Paste


  • The ARCTIC MX-iv does not contain whatsoever metal; thus, information technology does not impose the risk of shorting your arrangement.
  • It has a marginally superior thermal operation that is perfect for overclocking purposes.
  • One application of the MX-4 can last for 8 years.


  • Its iv-gram variant is more expensive than the NT-H1 considering they have nearly like performance.

Noctua NT-H1

Noctua NT-H1 Pro-Grade Thermal Compound Paste


  • The Noctua NT-H1 performs relatively groovy considering it is the cheaper of the 2.
  • The NT-H1 does not crave a curing time.
  • A 3.5 gram of the NT-H1 can last you lot for three to twenty applications with a 3-twelvemonth storing time.


  • It has shorter longevity; thus, you will have to reapply it more regularly.

The Final Verdict: ARCTIC MX-4 vs Noctua NT-H1

Although the real-life performances of both the ARCTIC MX-iv and Noctua NT-H1 are close, it volition make a huge difference if you are into overclocking. Since both brands are reputable, I suggest y’all pick out the cheaper pick. This is especially true if yous are simply looking for a thermal paste that will replace the stock thermal grease on your figurer. In that case, you can pick the Noctua NT-H1 since it is 2/3 the price of an Chill MX-4. Otherwise, go ahead and get an ARCTIC MX-four if performance is important to you.
