GD900 (Metal-Oxide/Non-Conductive/AliExpress Staple Grease/4.8 W/mK) Review

If you're looking up gd900 thermal grease specs after seeing it everywhere on AliExpress under a dozen different reseller names, here's who actually makes it.

GD900 is manufactured by Foshan High Conductivity Electronics under the 'GD' brand and resold under many storefront names, at 4.8 W/mK it's a step above the entry-level Halnziye HY-510/HY-710 in this catalog and it's also widely used for repairing ASIC miner hashboards, not just PCs.

Thermal Performance

4.8 W/mK sits close to the Halnziye HY-810 (4.63 W/mK) in this catalog, solidly mid-pack among the budget greases we carry.

Application

A relatively thick paste (cone penetration 310, viscosity ~33,000 mPa.s), sold in everything from small 5g bags to 30g pots depending on the reseller.

Safety

Volume resistivity above 1.0x10^14 ohm-cm confirms it's a strong electrical insulator, and oil separation is rated under 1.8%, so it shouldn't bleed much over time.
