The Halnziye HY2612 is the top model in Halnziye's thermal putty range. Halnziye rates it above 12 W/mK. In September 2026, Igor's Lab measured 15.1 W/mK at 1 mm, 19.1 W/mK at 2 mm and 20.5 W/mK at 3 mm layer thickness, ahead of every other putty in that comparison.
Like every putty, HY2612 is pressed into place and adapts to the gap. That makes it a fit for GPU memory, voltage regulators and M.2 SSDs, where components sit at different heights and matching a pad thickness is difficult.
