Description
The Ix Tech El Mirage is a copper-plated aluminum heatsink upgrade for compatible Bitaxe and Nerdaxe boards. Its four-point M3 mounting system applies more even pressure than a two-pin clip, helping the base remain flat against the ASIC package when installed correctly.
This listing offers the heatsink with or without a 2g tube of Thermalright TF7 thermal paste. The mounting hardware and fan holder are included with both variations; the miner and 40mm fan are not included.

Compatible Miners
The El Mirage is designed around the established Bitaxe/Nerdaxe four-hole mounting pattern. Direct compatibility includes:
| Miner | Compatibility note |
|---|---|
| Bitaxe Gamma 600, 601, and 602 | Direct four-hole single-chip Bitaxe fit. |
| Bitaxe Supra | Direct single-chip Bitaxe fit. |
| Bitaxe Ultra and Max | Direct single-chip Bitaxe fit. |
| Bitaxe Gamma Duo 650 | Compatible Gamma Duo mounting layout; confirm fan and enclosure clearance. |
| Nerdaxe Gamma | Direct compatible Nerdaxe mounting pattern. |
| Nerdaxe Ultra | Direct compatible Nerdaxe mounting pattern. |
Not a direct-fit upgrade for: Bitaxe GT 801, Bitaxe Touch, Naja Duo, NerdQaxe++, Gamma Hex, BitForge Nano, or other boards with different ASIC spacing, mounting-hole patterns, cooler footprints, or enclosure clearance.
About the Benchmark Data
Solo Satoshi reference testing on one Bitaxe Gamma 602 held the reported ASIC temperature near 60°C across several elevated frequency and voltage settings. At the upper settings, voltage-regulator temperature rose substantially and became the practical thermal constraint.
These observations demonstrate one test unit, not a guaranteed result. ASIC quality, paste application, mounting pressure, fan performance, ambient temperature, board revision, power supply, firmware, frequency, and voltage all affect temperatures and stability.
Installation
- Shut down the miner, disconnect power, and let the board cool.
- Photograph fan orientation and cable routing before disassembly.
- Remove the fan, stock heatsink, and mounting hardware without flexing the PCB.
- Clean the ASIC package and heatsink base with high-percentage isopropyl alcohol and a lint-free material; let both dry.
- Apply a thin, complete layer of compatible thermal paste.
- Align the El Mirage over the ASIC and all four PCB mounting holes.
- Install the four M3 screws and locking nuts loosely, then tighten gradually in a diagonal pattern. Do not overtighten or bend the PCB.
- Install the fan holder and 40mm fan, reconnect the fan, and confirm that no cable touches the blades.
- Start at stock settings and verify fan operation, ASIC temperature, regulator temperature, errors, and stability.
