3M Thermally Conductive Acrylic Interface Pad 5590H vs Parker Chomerics THERM-A-GAP PAD 80: Comparison
3M Thermally Conductive Acrylic Interface vs Parker Chomerics THERM-A-GAP PAD 80: the thermal conductivity difference
Expect a near tie. The closest thing to a difference is thermal conductivity, 3M Thermally Conductive Acrylic Interface 2.08 W/mK against Parker Chomerics THERM-A-GAP PAD 80 8.3 W/mK. There is a split on reapplication interval as well, No reapplication needed; self-adhesive one-time application on the 3M Thermally Conductive Acrylic Interface versus No reapplication needed; reusable silicone gap filler on the Parker Chomerics THERM-A-GAP PAD 80. They differ on conductivity source too, https://multimedia.3m.com/mws/media/920112O/3m-thermally-conductive-acrylic-interface-pad-5590h-technical-data-sheet.pdf on the 3M Thermally Conductive Acrylic Interface versus https://ph.parker.com/us/en/product-list/therm-a-gap-pad-80-thermally-conductive-gap-filler-pads on the Parker Chomerics THERM-A-GAP PAD 80.
3M Thermally Conductive Acrylic Interface vs Parker Chomerics THERM-A-GAP PAD 80: which one fits your build
The 3M Thermally Conductive Acrylic Interface suits 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 not the one for builds where silicone pads are acceptable and higher conductivity is wanted. The Parker Chomerics THERM-A-GAP PAD 80 is the one to take for high-power component gap filling and high-end CPU/GPU, though it is not built for budget-conscious low-power builds. 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 Parker Chomerics THERM-A-GAP PAD 80 (6.8/10): an industrial-grade gap pad from Parker Chomerics, reliable but aimed more at OEM and industrial use than PC building.
Frequently asked questions
Do the 3M Thermally Conductive Acrylic Interface and Parker Chomerics THERM-A-GAP PAD 80 differ on compound type?
Yes. Compound Type reads Acrylic Pad on the 3M Thermally Conductive Acrylic Interface versus Silicone-Based Pad on the Parker Chomerics THERM-A-GAP PAD 80.
Is the Electrical Conductivity the same on the 3M Thermally Conductive Acrylic Interface and Parker Chomerics THERM-A-GAP PAD 80?
It is. Both are listed at Insulating, so it is not a reason to pick one over the other.
