Corsair XTM50 High Performance Thermal Compound Paste

Bottom line: The Corsair XTM50 High Performance Thermal Compound Paste ($14.99 on Amazon as of 2026-10-06): Ultra-low thermal impedance beats common paste on CPU and GPU temps; main trade-off: zinc oxide can't match liquid metal compounds on peak heat transfer.

Pros & Cons

Pros

  • ✓ Ultra-low thermal impedance beats common paste on CPU and GPU temps
  • ✓ 5g tube covers roughly 8-10 standard CPU applications
  • ✓ Includes application stencil plus spreader for consistent, repeatable layers
  • ✓ Non-conductive zinc oxide formula won't short pins or SMD components
  • ✓ Low viscosity fills machining channels and abrasions on the IHS

Cons

  • ✗ Zinc oxide can't match liquid metal compounds on peak heat transfer
  • ✗ Stencil is sized for desktop CPUs, not bare GPU dies or laptops
  • ✗ No stated cure time or thermal conductivity (W/mK) figure published
  • ✗ 5g is more than most builders need for a single one-time install

Manufacturer description

The Corsair XTM50 is a 5-gram tube of premium zinc oxide thermal compound built for enthusiasts who want lower CPU and GPU temperatures without the risk that comes with liquid metal. Its ultra-low thermal impedance improves heat transfer between your processor and cooler compared to common thermal paste, and the low-viscosity formula flows into the microscopic abrasions and machining channels on an IHS or cold plate where air pockets normally form. That gap-filling behavior is what turns a good cooler into a fully effective one. Application is handled for you: XTM50 ships with an application…

SpecPicks Verdict

SpecPicks scored Corsair XTM50 High Performance Thermal Compound Paste using a rating × review-volume × price-fit model applied to published specs and reviews across the retro cpu coolers & fans category. Corsair's retro cpu coolers & fans lineup sits within the broader category mid-tier; price and specs are the deciding factors over brand loyalty here. Judge it on the specification table and the price rather than on sentiment: check the figures that decide your use case, then put it side-by-side with two or three close alternatives in the Compare tool before clicking through.

Common buyer scenarios for retro cpu coolers & fans of this kind: matching it to an existing build, replacing a failing part, or upgrading from a previous-generation equivalent. Check the spec table below against your current setup — particularly socket / form-factor / power-rating fields — and confirm compatibility on the retailer's listing before purchase. Prices and stock are set by the retailer and may have moved since this page was last updated.

Frequently Asked Questions

How many applications do you get out of a 5 gram tube?

A standard desktop CPU application uses roughly 0.5g, so a 5g tube typically covers 8-10 installs. Coverage varies with IHS size and how thick you spread it.

Is Corsair XTM50 electrically conductive?

No. XTM50 is a zinc oxide based compound that is non-conductive and contains zero volatile compounds, so contact with socket pins or nearby components won't cause a short.

Can I use XTM50 on a GPU as well as a CPU?

Yes. Corsair rates XTM50 for installing new or replacing existing compound on both CPUs and GPUs to improve heat transfer and lower temperatures.

Do I need to buy an applicator separately?

No. The kit includes an application stencil and a spreader, so you can lay an even layer on your CPU without estimating a pea-sized dot by eye.

How often does XTM50 need to be reapplied?

Corsair describes it as a high-stability liquid compound that lasts for years with no drying, cracking, or change in consistency. Check the product listing for current warranty terms.
