Grey thermal paste in a 30g syringe tube

Ruth's sister

Ruth's sister GD900 30g thermal paste

SKU CH-FHQD-BTP7W

Grey thermal compound rated above 4.8 W/m·K in a 30 g syringe for CPU and heatsink applications

  • High thermal conductivity above 4.8 W/m·K for efficient heat transfer
  • Wide operating range from -50 °C to 240 °C suits extreme conditions
  • Non-drying, non-volatile formula maintains performance over time
  • Non-toxic, non-corrosive grey paste safe for all CPU applications
  • 30 g syringe provides enough compound for multiple installations

30 g GD900 thermal compound

The grey silicone-based paste ships in a 30 g syringe and is rated for thermal conductivity above 4.8 W/m·K. It is intended for CPU and heatsink interfaces in desktop or laptop builds. The compound remains stable across an operating range of -50 °C to 240 °C.

Non-conductive silicone limits

The material is electrically insulating, so it will not cause shorts if it spreads onto nearby components. It is not a metal-based liquid metal and therefore cannot match the peak conductivity of gallium alloys. The paste is designed for standard heatsink mounting pressure rather than bare-die direct-die applications.

4.8 W/m·K conductivity threshold

Thermal conductivity exceeding 4.8 W/m·K determines whether this paste meets the cooling budget for a given processor and heatsink combination. Builders targeting higher heat loads may require compounds with substantially higher rated conductivity.

Questions about this item

Should I pick the 30 g tube or is there another size?

The listing shows only the 30 g tube of GD900 paste, so that is the sole option.

What does the >4.8 W/m·K conductivity figure mean when the paste is between a CPU and cooler?

It indicates the compound moves heat across the interface faster than many standard pastes, helping lower core temperatures under load.

The paste is rated from –50 °C to 240 °C — does that limit which coolers or CPUs I can use it with?

The range covers virtually every desktop and laptop processor and cooler combination, so no practical restriction applies.
