GRAPHENEX

Ultra High Performance Graphene Heat Spreader Sheet

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.

Suitable for:

· Laptops & compact systems (hotspots, tight tolerances)

· Gaming PCs & high-end systems

· GPUs and hotspot-prone areas (layout dependent)

· Consoles (PS4/PS5, Xbox®) for service/upgrade use

· Workstations, small servers, multimedia systems

· Air cooling, AIO and custom loops (as a heat spreader in a sandwich)

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 & 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 needed.

Why a Sandwich Application

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

· absorb concentrated hotspot heat,

· spread it across a larger area,

· deliver it more evenly into the heatsink/cold plate.

To make this work, you need a TIM layer on both sides (paste or PCM) to couple surfaces properly.

Recommended Application

CPU/GPU Hotspot Sandwich (recommended):

1. CPU/GPU DIE / chip

2. Thermal paste or PCM (thin layer)

3. GRAPHENEX sheet

4. Thermal paste or PCM (thin layer)

5. Heatsink / cold plate

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

FAQ

Can I use GRAPHENEX without paste or PCM?

No. GRAPHENEX is a heat spreader, not a TIM. Use it in a sandwich with paste or PCM.

Where does GRAPHENEX help most?

Hotspot-heavy applications, where spreading heat across a larger area improves cooler efficiency.

Is GRAPHENEX compatible with liquid cooling?

Thermal pads: · have higher thermal resistance · are designed to bridge gaps, not eliminate them · work under controlled compression, not direct die pressure

Is GRAPHENEX electrically conductive?

Yes. Apply carefully and avoid electrical contact.
