High-Conductivity Thermal Putty for GPU and Memory
UPSIREN UX PRO Ultra is a gummy thermal compound rated at 16.8 W/m·K conductivity, supplied in a 20 g syringe. It targets enthusiasts replacing factory thermal pads on graphics cards, memory modules or similar components where a conformable, high-performance interface material is required.
Replaces Pads Up to 3 mm Without Electrical Risk
The putty fills gaps up to 3 mm thick, eliminating the need to stock multiple pad thicknesses. Its non-electrically conductive formula prevents short circuits if it spreads beyond the die, and the tacky texture holds position during heatsink installation without curing time.
Operates From -50 °C to 200 °C With No Oil Bleed
Long-term stability is rated from minus 50 °C to 200 °C, with short-term tolerance to 250 °C. The fully cured, non-bleeding compound maintains contact pressure over years, but the single 20 g portion limits coverage to a few GPU or memory arrays rather than large-scale builds.

Questions about this item
How thick a gap can the 16.8 W/m·K putty fill while still conducting heat?
The putty replaces soft thermal pads up to 3 mm thick, so it bridges gaps that pads of that thickness would cover.
What temperature does the putty reach inside a GPU running all day?
Long-term operating range is -50 to 200 °C; the material itself withstands heating to 250 °C without degrading.
What must already be in place for the putty to work on a graphics card?
A heatsink or cold plate that presses down on the GPU die and memory chips so the tacky putty makes full contact.
