Alphacool Apex Thermal Pad Soft 18W/mK vs Halnziye HY-810: Comparison

Alphacool Apex Thermal Pad Soft 18W/mK vs Halnziye HY-810 thermal conductivity compared

These two are close on paper, and thermal conductivity is the only measure that separates them at all: Alphacool Apex Thermal Pad Soft 18W/mK 17.8 W/mK against Halnziye HY-810 4.63 W/mK. They differ on recommended use too, High-end CPU/GPU on the Alphacool Apex Thermal Pad Soft 18W/mK versus Mainstream CPU/GPU on the Halnziye HY-810. There is a split on conductivity source as well, https://shop.alphacool.com/en/shop/thermal-conductant/thermal-pads/waem-alphacool-apex-thermal-pad-soft-18w/mk-120x20x1mm on the Alphacool Apex Thermal Pad Soft 18W/mK versus https://www.halnziye.net/HY810xilie/685.html on the Halnziye HY-810. They differ on paste segment too, Pad on the Alphacool Apex Thermal Pad Soft 18W/mK versus Standard Paste on the Halnziye HY-810.

Which should you buy, Alphacool Apex Thermal Pad Soft 18W/mK or Halnziye HY-810?

Take the Alphacool Apex Thermal Pad Soft 18W/mK for high-end CPU/GPU, VRM/MOSFET, and memory-module cooling wanting the highest independently-measured W/mK figure among this catalog's pads. It is equally the pick for builds needing a documented electrical safety spec sheet (volume resistance, dielectric breakdown) rather than a generic non-conductive claim. It is not the one for buyers who specifically want Eisschicht's softer, more paste-like conforming fit for delicate uneven surfaces. Buy the Halnziye HY-810 for budget gaming builds and shops doing volume repastes, though it is not built for overclocking and delidded/direct-die use. Our rating of the Alphacool Apex Thermal Pad Soft 18W/mK (6.8/10): A soft, high-conductivity pad aimed at high-end builds, though it lacks the independent review base of the paste side of Alphacool's lineup. Our rating of the Halnziye HY-810 (5.6/10): A mid-tier budget grease from Halnziye, reasonable value for casual builds.

Frequently asked questions

Do the Alphacool Apex Thermal Pad Soft 18W/mK and Halnziye HY-810 differ on max operating temperature?

Yes. Max Operating Temperature reads 150 C on the Alphacool Apex Thermal Pad Soft 18W/mK versus 180 C on the Halnziye HY-810.

Is the Electrical Conductivity the same on the Alphacool Apex Thermal Pad Soft 18W/mK and Halnziye HY-810?

It is. Both are listed at Insulating, so it is not a reason to pick one over the other.
