EK-Quantum Vector³ RTX 5080/90 Thermal Pad Kit Review

EK-Quantum Vector³ RTX 5080/90 Thermal Pad Kit is a genuine EK replacement thermal pad set for EK-Quantum Vector³ GPU water blocks fitted to RTX 5080 and RTX 5090 graphics cards, restoring thermal contact on VRAM and power-delivery components.

If you're rebuilding or servicing an EK-Quantum Vector³ block on an RTX 5080 or 5090, this is EK's own replacement pad kit rather than a generic third-party cut. It ships with twelve pads in six different sizes and a uniform 1-3mm thickness range so you get the correct thickness for VRAM, MOSFETs, and other contact points without trimming a single sheet down for every component.

What's in the kit

Twelve reusable, electrically non-conductive thermal pads pre-cut to the sizes EK's own Vector³ blocks require: 2x 8x16x2mm, 2x 55x16x2mm, 1x 27x16x2mm, 3x 120x12x1mm, 3x 120x6x2mm, and 1x 30x15x3mm. Each pad has natural tack on one side and ships under a protective foil that must be peeled before installation.

Compatibility

Designed for EK-Quantum Vector³ water blocks covering RTX 5090 Founders Edition, Astral, Suprim, TUF, and Master variants, plus RTX 5080/5070 Ti TUF and Astral blocks. Check your specific block's installation manual for correct pad placement.
