Prolimatech PK-1 Nano Aluminum (Aluminum Nano-Particle/Non-Conductive/Premium Grade/10.2 W/mK) Review
If you're comparing prolimatech pk-1 nano aluminum thermal compound specs against the PK-2 and PK-3 in this catalog, here's the breakdown.
PK-1 is Prolimatech's original nano-aluminum compound, and it's the thickest and most adhesive of the three PK pastes we carry, which makes it a good pick for anyone who wants a paste that stays put and won't need reapplying for years.
Thermal Performance
10.2 W/mK matches the PK-2 exactly, both trail the PK-3 Nano Aluminum already in this catalog, and both comfortably beat any of the Halnziye HY-series pastes we've reviewed.
Application
At 310,000 cP this is a thick, tacky compound, harder to spread thin than the PK-2, but that same tackiness is what gives it excellent long-term stability and low dry-out.
Safety
Non-electronically conductive and non-corrosive per Prolimatech, safe on aluminum and copper coolers alike.
