Pros & Cons

Pros

  • ✓ Re-sealable syringe stops the paste drying between service calls
  • ✓ 1.5g covers 4-6 applications, not a single reseat
  • ✓ 3.195 W/m-K rated conductivity beats standard silicone grease
  • ✓ 60% metal oxide formulation for higher heat transfer

Cons

  • ✗ Rated for CPUs up to 65W TDP only, not high-TDP chips
  • ✗ 3.195 W/m-K trails enthusiast pastes rated 8-12 W/m-K
  • ✗ 1.5g is small next to 4g+ tubes from cooling brands
  • ✗ Metal oxide content demands care near exposed pins

Manufacturer description

The StarTech.com SILVGREASE1 thermal paste is a metal oxide compound built for technicians who service machines rather than chase overclocking records. Each re-sealable 1.5g syringe holds enough paste for 4-6 applications, and the applicator seals between jobs so the compound does not dry out in a toolbox between service calls. StarTech rates the compound at 3.195 W/m-K thermal conductivity at 25 C, with a 60% metal oxide formulation that transfers more heat to your heat sink than standard silicone-based grease. The operating range spans -22F to 365F (-30C to 180C), so it holds up in warm…

Frequently Asked Questions

Is this thermal paste electrically conductive?

StarTech does not list an electrical conductivity rating. The compound is 60% metal oxide, so apply it carefully and avoid contact with pins or surface components. Check the product listing for full handling notes.

How many CPUs can I do with one 1.5g syringe?

StarTech rates the 1.5g tube at 4-6 applications. The syringe is re-sealable, so leftover paste stays usable for later reseats instead of drying out.

Will this work on a 105W or higher TDP gaming CPU?

StarTech specifies this paste for CPUs with a TDP up to 65W. For higher-wattage gaming or workstation chips, choose a compound rated for that thermal load.

What is the thermal conductivity of SILVGREASE1?

3.195 W/m-K at 25 C or greater, per StarTech. That is above standard silicone-based grease but below premium enthusiast compounds that publish figures in the 8-12 W/m-K range.

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

Yes. StarTech lists both CPUs and GPUs, plus integrated chipsets, as supported when paired with a heat sink. It rates the compound for -22F to 365F (-30C to 180C) operating temperatures.
