Common Applications

Extreme Odyssey is a silicone-based thermal interface pad rated at 12.8 W/mK with a density of 3.1 g/cc and a dielectric breakdown voltage of 9.8 KV. The pad is non-electrically-conductive, fire-retardant and compresses under mounting pressure to fill the gap between memory chips, VRMs, controllers or NAND flash and a heatsink or backplate. It is commonly used for GPU VRAM and VRM repads, NVMe SSDs under motherboard shields, laptop heat-pipe contact points, and DRAM modules under aftermarket coolers. Match thickness to the original pad or measure the air gap before purchase - too thin leaves the chip uncontacted, too thick lifts the entire heatsink off the GPU die.

Frequently Asked Questions

Q: How do I choose between 0.5mm, 1mm, 1.5mm, 2mm and 3mm?

A: Match the thickness of the pad you're replacing, or measure the physical gap between the chip and the heatsink. Going one step thicker is acceptable due to compression; going thinner leaves an air gap.

Q: Are the pads electrically conductive?

A: No. They are non-electrically-conductive silicone with a 9.8 KV breakdown voltage, so they can sit on top of exposed traces or SMDs.

Q: Is the pad reusable after one mount?

A: Not reliably. Each pad takes a permanent compression set after the first install, and removing it usually tears or thins it unevenly. Plan on cutting a fresh piece per service.

Q: What is the rated thermal conductivity?

A: 12.8 W/mK, with density 3.1 g/cc and Shore hardness 30-55 Sc per Thermalright's specifications.

Q: What can I use it on?

A: GPU VRAM, VRMs and inductors, M.2 NVMe SSDs, motherboard chokes and VRMs, laptop heat pipes, DRAM, SSD controllers, LED drivers and any application with a stable air gap between heat source and sink.
