The marketing is bigger number better. The reality is each has a different ideal application due to different viscosity. I buy 4 and 6, and still use MX-2 for some applications, and I only buy 30 g tubes. These 4 g tubes are all overpriced by comparison. Even a light DIYer can use a 8 g or larger tube for a decade if they want. Contrary to whatever AI nonsense pops up, none of it dries out in the tube, or loses performance until heat cycled. I know I have tubes of other assorted brands that are 20 years old now, and still fine. Bottom line, absolutely not worth 40% more for MX-7. DIYers are easy targets for high margin products with relatively low cost.

MX-4 is an older thermal paste that still works for basic repastes, especially on lower demand devices like a PS5, and long term use shows it can hold up for years without drying out or major degradation. The main appeal is value in larger tubes, since the tiny 4 gram pack is pricey per gram and bigger sizes can be only a few dollars more. The main drawback is that MX-6 or MX-7 is often viewed as the better buy for modern CPUs, with MX-7 offering a small performance edge and less pump out.

Common Questions (4)

  • The 4g tube works out to about $0.70 per gram, but commenters note the 8g tube is only about $0.50 to $3 more and the 45g tube can be far cheaper per gram. That makes the small tube look overpriced unless you specifically want a tiny amount.

  • MX-6 and MX-7 are repeatedly described as the better buy, with MX-7 offering slightly better performance and reduced pump-out. The main caveat is that MX-6/MX-7 can be very gooey and harder to apply, especially if you paste often.

  • MX-4 is described as an older formula that is fine for a PS5, but not recommended for current-generation CPUs and definitely not for GPUs. The practical takeaway is that it is better suited to lower-demand applications than newer high-performance builds.

  • It reportedly does not dry out in the tube and can still perform normally after years of storage. Long-term use examples include tubes kept for 15 to 20 years and still being usable.

Exactly. The difference between pastes is limited. I used a 2007 tube for 15 years across multiple builds no issue. Used another MX-4 across 3 builds in 8 years, and all held up. Fours years of operation on CPUs that were less power efficient (and similar Watt rating to current gen) had negligible degregadation.

Spend more if you want, most paste is cheap, but don't expect miracles from a higher marketing number.

How much performance improvement for MX-7 over MX-4, just curious? Was it worth the 40% extra premium?
The MX-7 does have better performance by a small margin, but most of the praises I have heard have been a reduction in "pump out".
