3M Thermally Conductive Acrylic Interface Pad 5590H vs Thermal Grizzly Minus Pad Pro: Comparison
3M Thermally Conductive Acrylic Interface vs Thermal Grizzly Minus Pad Pro: the compound type difference
The first real difference is compound type: 3M Thermally Conductive Acrylic Interface Acrylic Pad against Thermal Grizzly Minus Pad Pro Silicone-Based Pad. Recommended use is not the same on both, Battery cooling, power electronics and HMI displays on the 3M Thermally Conductive Acrylic Interface versus High-end CPU/GPU on the Thermal Grizzly Minus Pad Pro.
Who each one is for
The 3M Thermally Conductive Acrylic Interface is the one to take for silicone-sensitive assemblies near optics, displays or connectors and power electronics and battery gap filling, though it is not the pick for high-end GPU memory or VRM cooling. It is the wrong buy for builds where silicone pads are acceptable and higher conductivity is wanted. Buy the Thermal Grizzly Minus Pad Pro for high-end GPU memory and VRM repads with uneven component heights and repads where the original pad thickness is uncertain, though it is not built for buyers who need a published W/mK, hardness or temperature rating. It is not the one for budget SSD or chipset pads, where Minus Pad 8 is enough. Our rating of the 3M Thermally Conductive Acrylic Interface (6.6/10): an industrial acrylic interface pad from an established materials manufacturer, aimed at OEM and repair use rather than enthusiast builds. Our rating of the Thermal Grizzly Minus Pad Pro (6.5/10): Thermal Grizzly's top pad in the Basic, Advance and Pro series, with conductivity it rates very close to Minus Pad Extreme and the most compressible formula of the three, a strong pick for uneven GPU memory gaps.
Frequently asked questions
Do the 3M Thermally Conductive Acrylic Interface and Thermal Grizzly Minus Pad Pro differ on viscosity?
Yes. Viscosity reads Firm, tacky acrylic polymer sheet on the 3M Thermally Conductive Acrylic Interface versus Grey pad with outstanding compressibility, the highest of Thermal... on the Thermal Grizzly Minus Pad Pro.
Is the Electrical Conductivity the same on the 3M Thermally Conductive Acrylic Interface and Thermal Grizzly Minus Pad Pro?
It is. Both are listed at Insulating, so it is not a reason to pick one over the other.
