Rectangular grey phase-change thermal pad 80 by 40 millimetres thin sheet

Corn Electronics

Corn Electronics PTM7950 80x40x0.2mm Phase Change Thermal Pad 8.5W/mK

SKU CH-M7SA-1AMST

Phase-change thermal pad measuring 80 by 40 by .2 mm that transitions at 45 °C and delivers 8.5 W/mK conductivity

Option 80x40x0.25mm

  • Phase change at 45°C activates automatically for optimal heat transfer
  • 5 W/m.K conductivity efficiently moves heat from CPU and GPU cores
  • 80 x 40 x 0.2 mm pad fits PS5 Steam Deck laptop M.2 SSD applications
  • Survives 150°C baking and 1000 thermal cycles for long-term reliability
  • Thermal impedance below 0.04°C cm²/W minimises contact resistance without shims

What this product is

The Corn Electronics PTM7950 is a phase-change thermal pad measuring 80 by 40 by 0.2 millimetres. It replaces traditional paste with a solid sheet that melts at 45 degrees Celsius to fill microscopic gaps between a processor and its cooler. The material is rated at 8.5 W/mK thermal conductivity.

How it fits into a build

The pad is cut to size for GPU dies, CPU heat spreaders, SSD controllers or similar flat surfaces in consoles, laptops and desktops. It requires no syringe, spreader or curing time; simply place the sheet on the die and mount the heatsink. The 0.2 millimetre thickness keeps clamp pressure predictable and avoids over-compression of delicate bare-die components.

Behaviour under sustained load

Honeywell PTM7950 passes 150 degree Celsius baking for 1000 hours and 1000 thermal cycles without degradation. Thermal impedance stays below 0.04 C cm squared per watt without a shim, so the interface remains stable during long gaming or compute sessions. The polymer phase-change system maintains wetability across typical operating temperatures, preventing pump-out or dry-out that can raise temperatures over time.

Questions about this item

How long does the PTM7950 pad maintain its thermal performance under continuous high temperatures?

The material passes 150°C baking for 1000 hours and 1000 thermal cycles, so it retains its low thermal impedance during sustained heavy use.

Does the pad generate any noise or increase power draw once the system runs all day?

It is a passive phase-change pad with no moving parts, so it adds no noise and draws no power at any workload.

What do I need to have ready before installing this 80x40x0.2mm pad on my GPU or CPU?

You need a clean, flat mounting surface and the correct clamping pressure from your cooler — no extra paste, shims or tools are required.
