Deal Details
ARCTIC Inc via Amazon has 4-Grams ARCTIC MX-4 Premium Performance Thermal Paste for Processors + Spatula on sale for $5.49. Shipping is free with Prime or on orders $35+.

Thanks to Deal Hunter Rokket for sharing this deal.

About this item:
  • Excellent Performance: ARCTIC MX-4 thermal paste is made of carbon microparticles, guaranteeing extremely high thermal conductivity. This ensures that heat from the CPU/GPU is dissipated quickly & efficiently
  • Safe Application: The MX-4 is metal-free and non-electrical conductive which eliminates any risks of causing short circuit, adding more protection to the CPU and VGA cards
  • High Durability: In contrast to metal and silicon thermal compound, the MX-4 does not compromise over time. Once applied, you do not need to apply it again as it will last at least for 8 years

ARCTIC MX-4 is a budget thermal paste that is easy to apply and delivers strong cooling performance. The paste is described as effective on CPUs and consoles, with good results from simple spread, blob, or X-pattern application. It is non-conductive, and the included spatula is optional since ordinary plastic utensils can do the job. The main caveat is shelf life after opening, since thermal paste can dry out over time, and higher-end alternatives like MX-7 or PTM7950 are mentioned for better performance or longer-lasting use. It is a solid low-cost option when you want dependable thermal transfer without paying much more.

Common Questions (5)

  • Yes. It applies easily and delivers very effective cooling performance, with users describing it as a strong, cheap thermal compound for CPUs and other heatsinks.

  • The 8g tube is the better value if you plan to use paste on more than one component. For a single heatsink, the 4g tube is enough, and the 4g deal can drop to $4.99 if you do not care about the included spatula.

  • MX-7 is described as having better thermal performance in several areas while still being non-conductive. It costs about $1.65 to $2 more, and the main tradeoff is that it does not include the spatula.

  • A tiny dab spread into the CPU heat spreader, followed by a larger dab before mounting the heatsink, is recommended to help fill micro-fissures. Another common approach is a simple blob-and-mount method, which is said to produce similar results.

  • It does have a shelf-life once opened and can dry out over time, though it is not described as separating like some silicone pastes. That makes it best to use within a reasonable period after opening rather than storing it indefinitely.

Good for use on a 5+ year old Series S? Not sure if it needs repasting or not but I just opened it and cleaned it out and feel like a repasting might have me set for another 3-5 years of not worrying about it.

It's funny product application has already been mentioned. Many YouTubers have done tests proving the actual application of the paste is nearly irrelevant. So spread it out carefully, or blob it on and smash the heatsink in place. Same end results.

Isn't the 8g tube a better deal for $5.99?

If you plan to use it for more than one component, yes but if it's just for one heatsink, no reason to get extra.

and these do have a shelf-life component to them, at least once the tube is opened. I don't think MX-4 separates like some silicone pastes do, but they all tend to dry out over time. I've even had a few bargain brand heatsinks and all-in-one coolers ship with generic white silicone that was dry/hard in the box.

I know it's $1.65 more, but the MX-7 has better performance in several areas while still maintaining non-conductivity. You don't get the spatula, but they're not really needed at all. That said, we're still talking under $8.
