Ruth's sister GD900 30g thermal grease gray

Thermal grease for CPU heatsinks

GD900 is a gray thermal compound supplied in a 30 g syringe for applying between a processor and its heatsink. The silicone-based paste uses a conductive nano formulation to fill microscopic gaps and improve heat transfer. It suits builders assembling or servicing desktop systems who need a reliable interface material.

Sustained thermal performance

With a rated thermal conductivity above 4.8 W/mK the paste maintains consistent heat flow during prolonged workloads rather than only in short bursts. The compound remains stable across an operating range from -50 °C to 120 °C, so it does not degrade or pump out when the CPU runs at high temperature for extended periods. Its specific gravity above 2.5 g/cm³ helps the layer stay in place under repeated thermal cycling.

Thermals noise and power

The grease itself adds no noise, draws no power and has no moving parts; it simply conducts heat from the die to the cooler. Because it is non-curing and non-corrosive, it does not affect fan acoustics or system power draw over time. The 30 g volume covers multiple applications, reducing the need for frequent replacement.
