PTM7950 31x50x0.25mm Phase Change Thermal Pad JOYJOM 8.5W/mK

Description

Product Overview

The PTM7950 Phase Change Thermal Pad by JOYJOM is engineered for high‑performance cooling in modern computing devices. Measuring 31x50x0.25 mm, the pad utilizes a proprietary polymer phase‑change material (PCM) that transitions from solid to liquid at approximately 45 °C. This transition enables the pad to fill microscopic gaps between a processor and its heatsink, dramatically reducing thermal resistance. With a thermal conductivity of 8.5 W/mK, the PTM7950 outperforms many conventional silicone greases and ceramic‑based pads, delivering faster heat transfer and more consistent temperatures under load.

Designed for a wide range of applications, the PTM7950 is compatible with CPUs, GPUs, M.2 SSDs, and popular gaming consoles such as the PlayStation 5, Steam Deck, and ROG Ally. The pad’s thin profile ensures a low‑profile fit, while its robust material composition provides durability through repeated heating and cooling cycles. The product complies with industry standards for thermal interface materials and has been tested for 150 °C baking durability for 1000 hours and 1000 thermal cycles, guaranteeing long‑term reliability.

Usage

When installing the PTM7950, clean both the component surface and the heatsink with isopropyl alcohol to remove any residue. Apply the pad directly onto the processor or memory module, ensuring full coverage without air bubbles. The pad will initially be solid; as the device reaches operating temperature, the PCM will melt and conform to the surface topology, creating an optimal thermal bridge.

This pad is ideal for enthusiasts who frequently overclock their CPUs or GPUs, as well as for professionals building compact workstations where space is limited. It also serves well in portable gaming devices, where efficient heat dissipation is critical to maintaining performance and battery life. The PTM7950 can be used in both new builds and as a replacement for aging thermal paste, offering a mess‑free, reusable solution that simplifies maintenance.

FAQ

Is the PTM7950 compatible with all CPU sockets?

Yes, the pad’s dimensions and flexible PCM allow it to conform to most standard CPU socket sizes, including LGA, PGA, and BGA formats.

Can I reuse the PTM7950 after removing it?

Absolutely. The PCM can be re‑melted and reapplied multiple times without losing its thermal performance, making it a reusable solution.

How does the PTM7950 compare to traditional thermal paste?

Unlike conventional paste, the PTM7950 provides a solid‑to‑liquid transition that fills microscopic gaps more completely, resulting in lower thermal resistance and more stable temperatures under load.

What is the recommended operating temperature range?

The pad operates effectively from -40 °C up to 150 °C, with optimal performance occurring when the PCM transitions around 45 °C.

Do I need any special tools to install the pad?

No special tools are required. A clean, lint‑free cloth and isopropyl alcohol are sufficient for surface preparation before applying the pad.
