Common Applications
The Bykski B-GRP-1.5-X is a silicone-based thermal pad rated at 6.0 W/mK and supplied as a 100 x 14 x 1.5mm strip. It is intended for the memory, MOSFET and VRM contact points under a full-cover GPU water block and is also a common replacement for the stock pads that ship with RTX 30 series, RTX 40 series and Radeon RX 6000 series Bykski blocks. The 1.5mm thickness is also used to replace 1.8mm pads in some kits when an extra-light contact pressure is desired; verify the gap with the original spec sheet first. Note that this is a thermal pad, not a thermal paste, despite some listings calling it grease.
Frequently Asked Questions
Q: What is the thermal conductivity?
A: 6.0 W/mK.
Q: What are the dimensions?
A: 100mm long, 14mm wide and 1.5mm thick.
Q: Where do I use this pad?
A: Under GPU water blocks for GDDR memory, MOSFETs and VRM contact points, and any other component where the original pad spec is around 1.5mm.
Q: Is this a thermal paste?
A: No. Despite some listings calling it grease, the B-GRP-1.5-X is a silicone thermal pad supplied as a solid strip.
Q: Can I use it to replace a 1.8mm pad?
A: Sometimes. Some Bykski kits accept 1.5mm where 1.8mm is listed if lighter contact pressure is acceptable; check the block's spec sheet for the exact gap before substituting.
