Top Arctic Thermal Paste Picks for 2026
Here are our current top arctic thermal paste picks, compared on real Amazon owner reviews, price, and features. Live prices update below.
ARCTIC has built a huge following among PC builders for one simple reason: its MX-series thermal paste delivers excellent, dependable performance at a rock-bottom price. The MX-4 in particular has become a default recommendation across the hobby — non-conductive, easy to apply, and stable for years. If you have searched for ARCTIC thermal paste, you are almost certainly looking for the MX line, and that is exactly where this guide starts.
Because shopping searches often mix ARCTIC with similarly named or competing compounds, we want to be completely upfront: only two products in this list are genuine ARCTIC paste — the ARCTIC MX-4 (standard and spatula-bundled versions). The remaining four are well-regarded rivals from other companies, included so you can see exactly how the alternatives stack up against ARCTIC’s offering. Note especially that ‘Arctic Silver 5’ is made by a different company (Arctic Silver, Inc.) and is not an ARCTIC product despite the similar name. Prices run from around $5.49 to around $14.99. Below is an at-a-glance comparison, then a closer look at each compound — clearly labelled by brand — and a buyer’s guide to ARCTIC’s MX paste and how to apply it well.

1. ARCTIC MX-4 (4 g) – Premium Performance Thermal Paste for All Processors
Prime ARCTIC MX-4 (4 g) - Premium Performance Thermal Paste for All Processors (CPU, GPU - PC, PS4, Xbox), Very high Thermal Conductivity, Long Durability, Safe Application, Non-Conductive, Non-capacitive

The ARCTIC MX-4 is the genuine ARCTIC product most people are searching for, and it remains the brand’s flagship value compound. At around $5.49 for a 4-gram tube, it offers strong, consistent thermal performance, is completely non-conductive and non-capacitive, and applies with a forgiving medium viscosity. It is the paste that built ARCTIC’s reputation, and it is the definitive ARCTIC pick on this list.
If you came here specifically for ARCTIC thermal paste, this is the one. The MX-4 needs no cure time, holds its performance for years without drying or pumping out, and is safe even if a little touches surrounding components. ARCTIC’s manufacturing consistency means every tube performs as expected, which is why it is recommended so widely. For a build, a re-paste, or a laptop service, the genuine ARCTIC MX-4 covers it reliably and cheaply — the natural first choice for anyone who trusts the ARCTIC name.
Pros: Genuine ARCTIC, non-conductive, generous 4g tube, excellent value, no cure time.
Cons: Sits a hair behind ultra-premium pastes on absolute peak temperatures.
2. ARCTIC MX-4 (incl. Spatula, 4 g) – Premium Performance Thermal Paste
Prime ARCTIC MX-4 (incl. Spatula, 4 g) - Premium Performance Thermal Paste for All Processors (CPU, GPU - PC), Very high Thermal Conductivity, Long Durability, Safe Application

This is the same genuine ARCTIC MX-4, packaged with a small spatula applicator — the most beginner-friendly way to buy ARCTIC’s flagship paste. At around $5.49 it matches the price of the standard tube, so the spatula effectively comes free. The tool lets you spread a precise, even layer by hand if you prefer that to the pea-dot method.
For anyone newer to ARCTIC paste or to re-pasting in general, this bundle takes the uncertainty out of application. You get the identical MX-4 compound — non-conductive, durable, easy to work with — plus a spatula to lay down a controlled, thin coat and smooth away excess. It is the same dependable ARCTIC performance, just with a little extra help in the box. If you want genuine ARCTIC MX-4 and value a guided application, this spatula version is the sensible way to buy it.
Pros: Genuine ARCTIC MX-4 plus a free spatula applicator, great for first-timers.
Cons: Spatula is optional; seasoned builders may not use it.
3. Thermal Grizzly Kryonaut – 1 Gram – Extremely High Performance Thermal Paste
Prime Thermal Grizzly Kryonaut - 1 Gram - Extremly High Performance Thermal Paste - for Demanding Applications and Overclocking CPU/GPU/PS4/PS5/Xbox
As an Amazon Associate we earn from qualifying purchases. Product prices and availability are accurate as of the date/time indicated.
Thermal Grizzly Kryonaut is the highest-performing compound here, but to be clear it is a Thermal Grizzly product, not an ARCTIC one. We include it as the benchmark rival so you can see what the absolute top of the non-liquid-metal class looks like. At around $8.99 for a 1-gram tube it costs more per gram than ARCTIC’s MX-4, and it targets enthusiasts chasing the lowest possible temperatures.
If you are weighing ARCTIC against the best alternative, this is the comparison that matters. Kryonaut’s very high thermal conductivity typically edges out the MX-4 by a small margin under heavy load — meaningful for overclockers, less so for everyday use. Against that, the MX-4 wins decisively on price and tube size. So the honest take: the genuine ARCTIC MX-4 is the better value for most people, while this Thermal Grizzly paste is the pick if you specifically want peak performance and accept it is not an ARCTIC product.
Pros: Top-tier temperatures, very high conductivity, the rival to beat ARCTIC on cooling.
Cons: Not an ARCTIC product; small 1g tube and higher cost per gram.
4. Noctua NT-H1 3.5g, Pro-Grade Thermal Compound Paste
Prime Noctua NT-H1 3.5g, Pro-Grade Thermal Compound Paste (3.5g)
As an Amazon Associate we earn from qualifying purchases. Product prices and availability are accurate as of the date/time indicated.
Noctua’s NT-H1 is another excellent rival to ARCTIC’s MX-4 — and again, to be transparent, it is a Noctua product rather than an ARCTIC one. At around $8.95 for a 3.5-gram tube it is renowned for longevity and ease of use, much like the MX-4, which makes it the closest like-for-like alternative on character. It is non-conductive, needs no cure time, and stays stable for years.
If you are deciding between ARCTIC and Noctua, the two are remarkably similar in spirit: both are forgiving, non-conductive, set-and-forget compounds with great reputations. The NT-H1 is a touch pricier than the MX-4 for broadly comparable everyday temperatures, and brand loyalty often decides it. The honest summary: the genuine ARCTIC MX-4 is the better-value default, but if you trust the Noctua name or are pairing it with a Noctua cooler, the NT-H1 is an equally dependable, if non-ARCTIC, choice.
Pros: Excellent longevity, non-conductive, easy to apply — the closest rival in feel to MX-4.
Cons: Not an ARCTIC product; slightly pricier than MX-4 for similar results.
5. Corsair TM30 Performance Thermal Paste, Ultra-Low Thermal Impedance
Prime Corsair TM30 Performance Thermal Paste | Ultra-Low Thermal Impedance CPU/GPU | 3 Grams|w/applicator, Silver for Desktop
As an Amazon Associate we earn from qualifying purchases. Product prices and availability are accurate as of the date/time indicated.
The Corsair TM30 is a capable rival compound — and, to keep things clear, a Corsair product, not an ARCTIC one. At around $7.76 it offers ultra-low thermal impedance in a non-conductive zinc-oxide formula, and it is a natural pick for builders already invested in Corsair gear. We include it so you can see how a mainstream-brand alternative compares with ARCTIC’s MX-4.
Set against the genuine ARCTIC paste, the TM30 is a solid everyday performer that transfers heat efficiently and applies cleanly, but it does not meaningfully outdo the MX-4, and it usually costs a little more for a smaller tube. Where it makes sense is brand consistency — pairing it with a Corsair cooler or AIO. The honest take: for pure value the ARCTIC MX-4 leads, but the Corsair TM30 is a respectable non-ARCTIC option if a single-brand build appeals to you.
Pros: Low thermal impedance, non-conductive, clean to apply, fits Corsair builds.
Cons: Not an ARCTIC product; pricier per gram than MX-4 with no real edge.
6. Arctic Silver 5 AS5-3.5G Thermal Paste
Prime Arctic Silver 5 AS5-3.5G Thermal Paste,Black, Grey
As an Amazon Associate we earn from qualifying purchases. Product prices and availability are accurate as of the date/time indicated.
Arctic Silver 5 is the most important name to clear up: despite the similar branding, it is made by Arctic Silver, Inc. and is NOT an ARCTIC product. This is the single biggest source of confusion when shopping for ‘ARCTIC’ paste, so we are flagging it plainly. At around $14.99 for a 3.5-gram tube it is the most expensive compound on this list, and it uses a long-established silver-based formula.
If you arrived expecting an ARCTIC product, this is not it — but it is still a respected enthusiast paste worth understanding. Arctic Silver 5 delivers good silver-loaded heat transfer, though it is very slightly capacitive (so apply carefully around surface-mount components) and benefits from a break-in period of several heat cycles to reach peak performance. Compared with the genuine ARCTIC MX-4, it costs significantly more, is fussier to apply, and is from a different company. The honest verdict: for value and simplicity the ARCTIC MX-4 is the smarter buy; choose Arctic Silver 5 only if you specifically want this classic silver compound and understand it is unrelated to ARCTIC.
Pros: Classic silver-based compound, large 3.5g tube, good heat transfer.
Cons: NOT an ARCTIC product; priciest here, slightly capacitive, needs break-in.
How to Choose ARCTIC (and ARCTIC-Style) Thermal Paste
First, know what ‘ARCTIC’ actually means when you shop. ARCTIC is the company behind the MX series — MX-4 and the newer MX-6 — and those are the products you want if brand authenticity matters to you. The biggest pitfall is ‘Arctic Silver 5’, which sounds related but is made by a completely separate company, Arctic Silver, Inc. If you specifically want genuine ARCTIC paste, look for the MX name; everything else on this list is a clearly different brand.
Once you have the brand straight, judge the MX line on its merits — and it holds up superbly. The MX-4 is non-conductive and non-capacitive, so it is safe for beginners, needs no cure time, and stays stable for years. That combination of safety, longevity and a sub-$6 price is exactly why it is recommended so widely. For the overwhelming majority of CPUs and GPUs at stock or with a sensible overclock, the genuine ARCTIC MX-4 is all the paste you need.
Understand where the rivals genuinely differ, so you can decide if leaving ARCTIC is worth it. Thermal Grizzly Kryonaut edges ahead on absolute peak temperatures for overclockers; Noctua’s NT-H1 matches the MX-4’s easygoing, long-life character almost exactly; Corsair’s TM30 suits single-brand Corsair builds. None of these dramatically beats the MX-4 for everyday use, and most cost more — so switch away from ARCTIC only for a specific reason like peak overclocking or brand consistency.
Finally, apply it properly, because technique matters more than the last degree of compound performance. A pea-sized dot in the centre, then clamping the cooler, spreads a thin even layer on most CPUs; the spatula-bundled MX-4 lets first-timers lay down a measured coat by hand. Avoid over-applying — excess paste insulates. Decide whether you want authentic ARCTIC simplicity (the MX-4) or a specific rival strength, keep the Arctic-Silver naming trap in mind, and pick the paste here that matches your real priority.
Frequently Asked Questions
Is Arctic Silver 5 the same brand as ARCTIC MX-4?
No — and this is the most common mix-up. Arctic Silver 5 is made by Arctic Silver, Inc., a completely separate company from ARCTIC, which makes the MX series (MX-4, MX-6). The names are similar but the products are unrelated. If you specifically want genuine ARCTIC paste, choose an MX-series tube; Arctic Silver 5 is a different, silver-based compound from a different manufacturer.
Which products in this guide are actually made by ARCTIC?
Only two: the ARCTIC MX-4 (4 g) and the ARCTIC MX-4 with spatula. Both are genuine ARCTIC products. The Thermal Grizzly Kryonaut, Noctua NT-H1, Corsair TM30 and Arctic Silver 5 are all made by other companies and are included as rival comparisons so you can see how the alternatives stack up against ARCTIC’s MX line.
Is ARCTIC MX-4 good enough, or should I buy a rival paste?
For the vast majority of users, the genuine ARCTIC MX-4 is more than good enough — it is non-conductive, long-lasting, easy to apply and very cheap. The rivals here only pull ahead in narrow cases: Thermal Grizzly Kryonaut for absolute peak overclocking temperatures, or Corsair TM30 for a single-brand Corsair build. Unless you have a specific reason like that, the MX-4 is the smart, value-leading choice.
What is the difference between ARCTIC MX-4 and MX-6?
Both are genuine ARCTIC pastes. The MX-4 is the long-running, hugely popular value compound featured here, while the MX-6 is ARCTIC’s newer formulation aimed at slightly improved performance and an even easier application. For most builds the MX-4 remains an outstanding, cheaper choice; the MX-6 is worth a look if you want ARCTIC’s latest compound, but the MX-4 still represents the best value in the ARCTIC line.
