Graphene Liquid Cooling Film GrapheneCool Mass Produced: Cuts Chip Core Temperature by 40C at Just 0.1mm Thick

Thermal management company Thermal Graphene announced on March 19 that its graphene liquid cooling film GrapheneCool has entered mass production. This 0.1mm-thick cooling film uses nanofluid circulation within graphene microchannels for heat conduction, measured at reducing high-performance GPU core temperatures by 40 degrees Celsius.

GrapheneCool has a three-layer structure: a graphene thermal conductivity layer (thermal conductivity of 5,000 W/mK), a microfluidic channel layer (channel width of just 50 micrometers), and a copper base heat dissipation layer. Nanofluid circulates through microchannels absorbing chip heat, rapidly spreading across the entire cooling surface via the graphene layer.

Thermal Graphene has received product certification from both NVIDIA and AMD, with both companies planning to integrate GrapheneCool in their next-generation flagship GPUs. NVIDIA's thermal engineering director stated: "This cooling film solves the core thermal bottleneck we face on high-performance computing chips."

GrapheneCool is priced at $15 per sheet (standard GPU size) with monthly production capacity already at 1 million units. The company expects to enter the laptop and smartphone markets in 2031.
