3M Thermally Conductive Acrylic Interface Pad 5590H vs Alphacool Silver Grease Thermal Paste: Comparison
What is the difference between 3M Thermally Conductive Acrylic Interface and Alphacool Silver Grease Thermal Paste?
They are built to different briefs, and viscosity shows it, 3M Thermally Conductive Acrylic Interface Firm, tacky acrylic polymer sheet against Alphacool Silver Grease Thermal Paste Does not sweat/bleed oil over time; manufacturer states it.... Recommended use is not the same on both, Battery cooling, power electronics and HMI displays on the 3M Thermally Conductive Acrylic Interface versus Mainstream CPU/GPU; marketed by Alphacool as an affordable entry-level... on the Alphacool Silver Grease Thermal Paste. They differ on paste segment too, Pad on the 3M Thermally Conductive Acrylic Interface versus Standard Paste on the Alphacool Silver Grease Thermal Paste.
Which should you buy, 3M Thermally Conductive Acrylic Interface or Alphacool Silver Grease Thermal Paste?
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 not built 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. it is not the pick for buyers who need a large syringe for multiple full-size applications. It is equally the pick for budget builds and spare-parts stock where a cheap, reliable paste is enough. Avoid it for high-end overclocking or delidded setups wanting a documented high W/mK figure. 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 Alphacool Silver Grease Thermal Paste (5.6/10): A basic silicone-based grease from Alphacool, mainstream tier.
Where the two are identical
Everything else lines up. Electrical conductivity read the same on both, so those are not worth weighing.
