Description
Thermalright TF7 is a high-performance, non-conductive thermal compound built for any application where heat needs to move efficiently from a chip into a heatsink. With 12.8 W/m·K of thermal conductivity, a silicone-based carrier that resists pump-out, and a service life of up to two years under sustained load, TF7 is the practical choice for Bitcoin home miners, GPUs, laptops, mini PCs, single-board computers, and any DIY electronics build that runs hot.
Each tube ships as a sealed 2g syringe of compound. The 2g format covers dozens of small ASIC die applications such as Bitaxe, Nerdaxe, plus multiple full-size CPU and GPU repastes on the same tube.

Specifications are published by Thermalright on the official TF7 product page. The 12.8 W/m·K rating places the TF7 well above the unbranded compound that ships pre-applied on most stock heatsinks and stock CPU coolers.
Compatibility
The TF7 is a true general-purpose thermal paste. Because it is non-electrically-conductive and non-corrosive, it is safe on every exposed chip, MOSFET, voltage regulator, and PCB component it might contact. Common applications include:
- Bitcoin home miners. ASIC repastes on the Bitaxe family, Nerdaxe and NerdQaxe family, and other open-source SHA-256 miners.
- Desktop CPUs. Intel and AMD processors with or without an integrated heat spreader.
- GPUs. Discrete graphics card repastes, including the main GPU die.
- Laptops and mini PCs. Repasting a laptop CPU or APU to recover lost thermal headroom after years of pump-out.
- Single-board computers. Raspberry Pi heatsinks, Jetson modules, ESP32-based projects, and other SBC builds.
- Heatsink upgrade installs. Any time you remove and reseat a heatsink.
The TF7 bonds well to bare copper, nickel-plated copper, anodized aluminum, and direct-die silicon, so there are no surface-prep limitations beyond standard 90 percent isopropyl alcohol cleaning.
Application
- Power down the device and unplug it. Remove the heatsink mounting screws or push-pins.
- Lift the heatsink straight up. Clean the old paste off the chip and the heatsink base with 90 percent isopropyl alcohol and a lint-free cloth.
- Apply the TF7. For small dies such as an ASIC chip, use a pea-sized drop (about half a grain of rice) in the center. For larger surfaces such as a desktop CPU IHS, use a slightly larger pea or a thin spread.
- Reseat the heatsink straight down, then re-secure the mounting hardware in a diagonal pattern so pressure is even.
- Power on. Monitor temperatures for 15 minutes under load. Expect immediate improvement, with full steady-state performance after roughly 50 to 100 hours of normal operation.
- Same-day shipping from Houston, Texas. Orders placed before 12PM CST ship the same business day.
