Product Description

WISKA Honeywell PTM 7950 Thermal Pad for GPU, SSD, Hard Disk and Graphic Chips

Superior Heat Dissipation: The WISKA PTM7950 thermal pad offers exceptional thermal conductivity of 8.5 W/m·K, acting as a thermal putty for enhanced heat transfer. Ideal as a thermal pad for laptop, GPU, CPU, and other high-performance components.Phase Change Technology: WISKA thermal pads for GPU utilize Honeywell PTM 7950’s phase change at 45°C to ensure optimal contact and thermal transfer, softening during use and re-solidifying for reuse, outperforming traditional thermal tape.

WISKA Honeywell PTM7950, a high thermal conductive Phase Change Material (PCM) in pad format, was designed to minimize thermal resistance at interfaces and has the great excellent long term reliability.Based on a novel polymer PCM system, this material exhibits excellent wetting at interfaces during typical operating temperature range, resulting in very low surface contact resistance.A proprietary filler material provides high thermal conductivity 8.5W/m ·K and a low thermal impedance (<0.04˚C cm²/W), suitable for high performance IC devices.

Installation Steps

Step 1

Tear off the protective film on the phase change side.

Step 2

Apply to the heat sink and press to smooth it out.

Step 3

Carefully tear off the other side of the protective film.

Step 4

Finally, the heat dissipation is assembled on the machine.

How the PTM7950 thermal pad works ?

At room temperature, thermal conductive phase change materials remain solid and cannot discharge air from the interface (Picture 1)

As the temperature increases, the phase change thermal conductive material becomes softer and the air at the interface begins to be discharged, and the temperature also begins to decrease (Picture 2)

When the phase change thermal conductive material reaches the phase change temperature(45°C), it becomes liquid and can greatly wet the interface, discharge the air inside the interface, reduce the interface thermal resistance, and transfer heat as much as possible; When the device is in a non working state, the phase change thermal conductive material becomes solid again, but maintains 100% complete wetting of the interface (Picture 3)

Enhanced Reliability: The WISKA PTM 7950 thermal pad is proven to endure 1000 hours at 150°C and 1000 thermal cycles without degradation, maintaining ultra-low thermal impedance, making it an ideal thermal sheet for heat resistance needs.

Optimized Size and Versatility: The WISKA PTM 7950 thermal pad’s 40x80x0.2mm dimensions suit a variety of devices, including thermal pads for laptop, thermal pad for cpu, and ssd thermal pad. It’s a versatile thermal sheet for tech enthusiasts.

All-In-One Installation Kit: Each WISKA PTM7950 thermal pad includes a screwdriver, spatula, cleaning brush, and wipes, ensuring easy installation for thermal pad for ssd m.2 nvme and thermal putty laptop applications. Ideal for DIY enthusiasts.
