3M Thermally Conductive Acrylic Interface Pad 5590H vs StarTech.com StarTech SILV5-THERMAL-PASTE: Comparison
3M Thermally Conductive Acrylic Interface vs StarTech.com StarTech SILV5-THERMAL-PASTE: the thermal conductivity difference
These two are close on paper, and thermal conductivity is the only measure that separates them at all: 3M Thermally Conductive Acrylic Interface 2.08 W/mK against StarTech.com StarTech SILV5-THERMAL-PASTE 3.195 W/mK at 25C. They differ on recommended use too, Battery cooling, power electronics and HMI displays on the 3M Thermally Conductive Acrylic Interface versus Mainstream CPU/GPU on the StarTech.com StarTech SILV5-THERMAL-PASTE. Conductivity source is not the same on both, 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://www.startech.com/en-us/computer-parts/silv5-thermal-paste on the StarTech.com StarTech SILV5-THERMAL-PASTE. There is a split on paste segment as well, Pad on the 3M Thermally Conductive Acrylic Interface versus Standard Paste on the StarTech.com StarTech SILV5-THERMAL-PASTE.
3M Thermally Conductive Acrylic Interface vs StarTech.com StarTech SILV5-THERMAL-PASTE: which one fits your build
Buy the 3M Thermally Conductive Acrylic Interface for silicone-sensitive assemblies near optics, displays or connectors and power electronics and battery gap filling, though it is the wrong buy 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 StarTech.com StarTech SILV5-THERMAL-PASTE suits IT technicians servicing multiple workstations and mainstream desktop CPU/GPU re-pasting, though it is not the pick for high-end overclocking or delidded direct-die use and single-application home users (single syringe SILVGREASE1 is more economical). 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 StarTech.com StarTech SILV5-THERMAL-PASTE (5.6/10): A five-pack of re-sealable syringes built for IT technicians managing several machines, not a performance-focused pick.
What 3M Thermally Conductive Acrylic Interface and StarTech.com StarTech SILV5-THERMAL-PASTE have in common
The common ground is wider than the gap: electrical conductivity are identical here.
