How these pads compare to JOYJOM
Thermal Grizzly Minus Pad Extreme 120x20x1.5mm
The Thermal Grizzly Minus Pad Extreme measures 120x20x1.5mm, which is far narrower than the JOYJOM sheet. Its 1.5mm thickness is six times thicker than the 0.25mm JOYJOM pad. This makes it suitable for filling larger gaps on GPU memory modules where the thin JOYJOM sheet would fail to bridge the distance. The self-adhesive backing simplifies installation compared to the phase-change material in the JOYJOM product. You get a ready-to-use pad without needing to manage the phase-change activation process. This option is better for builders with narrow, deep gaps rather than large, flat surfaces.
Thermal Grizzly Minus Pad Advance 100x100x1.0mm 2-Pack
The Thermal Grizzly Minus Pad Advance comes in 100x100x1.0mm sheets. This size is much smaller than the 400x160mm JOYJOM sheet. The 1.0mm thickness is four times thicker than the JOYJOM pad. It is non-conductive, which offers safety when working near sensitive electronic components. The JOYJOM pad relies on phase change technology for its 8.5 W/m.K performance. This Thermal Grizzly pad prioritizes flexibility and precise thermal management for small components like VRAM. It is a better choice if you need to cover multiple small areas with individual pads rather than one large continuous sheet.
Thermal Grizzly Minus Pad High Compression 1.0mm 2-Pack
The Thermal Grizzly Minus Pad High Compression measures 120x100x1.0mm. It is significantly smaller than the 400x160mm JOYJOM sheet. The 1.0mm thickness provides more material to fill gaps than the thin 0.25mm JOYJOM pad. It is non-conductive and flexible, making it safe for various GPU and SSD applications. The JOYJOM pad offers higher thermal conductivity at 8.5 W/m.K due to its phase change material. This Thermal Grizzly pad is a practical budget choice for users who need reliable padding without the complexity of phase-change activation. It suits those who prioritize ease of use and gap-filling capability over maximum thermal performance.
WithFlying 15.8 W/mK 100x100x2.5mm Thermal Pad
The WithFlying thermal pad measures 100x100x2.5mm. This is much smaller than the JOYJOM 400x160mm sheet. Its 2.5mm thickness is ten times thicker than the JOYJOM pad. It offers 15.8 W/m.K conductivity, which is nearly double the 8.5 W/m.K of the JOYJOM pad. This makes it ideal for filling wide gaps on GPUs or laptops where standard pads are too thin. The JOYJOM pad uses phase change material that activates at 45°C. The WithFlying pad is a durable, high-temperature solution for consoles and gaming devices. It is better for builders who need thick padding and high conductivity in a smaller footprint.
JOYJOM PTM7950 40x40x0.25mm Thermal Pad
The JOYJOM PTM7950 40x40x0.25mm thermal pad uses the same phase change material as the larger sheet. It measures 40x40mm, which is much smaller than the 400x160mm original. The 0.25mm thickness remains the same. This size is ideal for small GPU or CPU heatsink areas where the large sheet would be wasteful. It delivers excellent thermal performance for small components. You get the same 8.5 W/m.K conductivity and 45°C activation temperature. This option is better for users who need precise coverage for small areas. It requires careful handling of the phase-change material, just like the larger version.
NEW Games Order PS3 Copper Heatsink Shims
The NEW Games Order PS3 Copper Heatsink Shims are made of copper, not thermal pad material. They are designed for PS3 repair and cooling, not for modern PC phase-change applications. The shims are thick and rigid, unlike the flexible JOYJOM pad. They are suitable for filling gaps in console hardware rather than computer components. The JOYJOM pad offers 8.5 W/m.K conductivity and adapts to surface imperfections. These copper shims provide structural support and thermal transfer for specific console models. This option is only relevant for users maintaining PS3 hardware. It is not a direct alternative for general PC or GPU cooling needs.
