Halnziye HY2612 Thermal Putty Now Available at Amawi Technologies
Update, 28 October 2026: the HY2612 V2 is now available in two sizes, a 20 g jar (€24.99) and a 100 g jar (€89.99), both with a spatula and shipped from Germany. Order it here. The first batch is limited; more stock is already planned.
The HY2610 (10 W/mK) is back in stock as well.
We sell the latest version, HY2612 V2, sourced directly from Halnziye as an authorized reseller.
What Igor’s Lab measured
Halnziye rates the HY2612 at 12.0 W/mK. In September 2026, Igor’s Lab tested it on a TIMA5 analyzer and measured clearly more than the label promises:
| Layer thickness | Measured thermal conductivity |
|---|---|
| 1.0 mm | 15.1 W/mK |
| 2.0 mm | 19.1 W/mK |
| 3.0 mm | 20.5 W/mK |
| Highest reading (about 2.75 mm) | 21.6 W/mK |
In that comparison the HY2612 came out ahead of every other putty at each layer thickness tested the same way, including Thermal Grizzly TG Putty Pro, Honeywell HT10000 and Alphacool Apex X1. The values above are Igor’s Lab’s own measurements. Results in your build depend on the gap, the contact pressure and the cooler.
Where it fits in the Halnziye putty range
The HY2612 sits at the top of the range. It does not replace anything:
- HY236: 6 W/mK, pink, the entry point
- HY2610: 10 W/mK, the popular choice for GPU VRAM and VRM work
- HY2612: rated at 12.0 W/mK, for builds where every degree counts
Like the other putties, it is a moldable gap filler for GPU memory, voltage regulators and M.2 SSDs. You press it into place and it adapts to the gap, so there is no pad thickness to work out.
