Quantity

THERMAL HERO GRAPHENEX is an ultra-thin graphene sheet (0.025 mm) engineered for heat spreading in demanding electronics cooling scenarios. It is designed to address hotspots on CPU, GPU, RAM and chipset contact areas by distributing heat quickly across a wider surface.

Important: GRAPHENEX is not a standalone thermal interface material (TIM) and should not be used by itself. For reliable heat transfer, GRAPHENEX must be used in a sandwich application with thermal paste or PCM to properly fill micro-gaps and ensure consistent surface contact.

Why a Sandwich Application

Hotspots form locally on the DIE or chip area. GRAPHENEX acts as a heat spreader to:

absorb concentrated hotspot heat
spread heat across a larger surface
deliver it more evenly into the heatsink or cold plate

To make this work, a TIM layer is required on both sides (thermal paste or PCM) to properly couple the surfaces.

Recommended Application

CPU/GPU Hotspot Sandwich (recommended):

CPU/GPU DIE / chip
Thin layer of thermal paste or PCM
GRAPHENEX sheet
Thin layer of thermal paste or PCM
Heatsink / cold plate

Result: improved heat spreading, more stable temperatures and fewer hotspot spikes depending on system and mounting quality.

Suitable for

Laptops & compact systems (hotspots, tight tolerances)
Gaming PCs & high-end systems
GPUs and hotspot-prone areas
Consoles (PS4 / PS5 / Xbox®)
Workstations, small servers and multimedia systems
Air cooling, AIO and custom loops (as heat spreader)

Features & Benefits

Ultra-thin graphene composite sheet: 0.025 mm
Heat spreading to reduce hotspot concentration
Low thermal resistance when properly coupled (sandwich)
Temperature resistant up to approx. 400 °C
Flexible, cut-to-size, shape-stable
Long-lasting and corrosion-resistant
Electrically conductive (apply with care)

⚠️ Safety Note

GRAPHENEX is electrically conductive. Avoid contact with exposed traces, SMD components or pins. Use careful cutting and insulation measures where required.
