Phobya HeGrease Standard 3.5g syringe

Phobya HeGrease Standard is a thermal compound supplied in a 3.5g syringe with an included plastic spatula for precise application. The electrically non-conductive paste targets PC builders and up-graders who want improved heat transfer between CPU, GPU or chipset and their coolers without the risk of short circuits. Its screw-on cap keeps unused compound fresh for future maintenance sessions.

6W/mK conductivity and 85000cps viscosity

The compound delivers a thermal conductivity of 6W/mK, providing measurable cooling gains for stock and moderately overclocked components when applied in a thin layer. The 85000cps viscosity allows easy spreading without excessive force, ensuring minimal gap between die and cold plate. Extreme overclockers chasing the absolute lowest temperatures may find the conductivity ceiling limiting compared to premium metal-based alternatives.

Upgrade from basic silicone or stock paste

Replacing generic silicone grease or dried-out factory paste with HeGrease Standard yields an immediate drop in junction temperatures for very little effort and cost. The jump is worth it whenever the existing interface material is several years old, has been disturbed during a cooler swap, or when the system runs louder than desired under load. Users requiring sub-ambient or liquid-nitrogen cooling should look elsewhere.

Questions about this item

Will the 6W/mK conductivity and 85000cps viscosity work with an older CPU cooler that has a slightly uneven base?

Yes, the 85000cps viscosity lets the paste spread into a very thin layer, filling microscopic gaps on an uneven cooler base for better contact.

How can I confirm the paste is applied correctly after mounting the cooler?

Check that CPU or GPU temperatures under load drop compared to the previous compound; a thin, even spread visible when the cooler is removed also shows proper application.

Does the 3.5g syringe include a tool for spreading, or do I need to buy one separately?

A plastic spatula is included in the box, so no extra tool is required; the screw-on cap also keeps any unused paste fresh.
