Bitaxe Gamma – VR Cooling Backplate
When overclocking the Bitaxe Gamma, the ASIC chip often isn't the bottleneck (especially with a good heatsink like Copperzilla). The voltage regulator section barely gets any direct airflow on the stock layout.
This backplate holds a 40x40x20mm fan (the stock Bitaxe fan or any other compatible 40x40x20mm one) angled to blow directly on the VR components.
Result (750MHz / 1.2V / 25.2W, 1.6 Th/s, identical settings before/after):
VR temp: 71°C → 55°C (–16°C, over 20%+ reduction with only 50% fan speed)
More thermal headroom before the VR becomes your overclocking limit instead of the ASIC
BOM
1× printed backplate
1× 40x40x20mm fan (stock or aftermarket)
2× M3x8 screw
2× M3x25 socket head cap screw
2× M3 nut
Y-Fan cable
Assembly
Mount backplate to the Bitaxe (2× M3x8)
Mount fan to backplate with 2× M3x25 + M3 nuts, angled toward the VR section
Reconnect fan cables (front and back Fan with Y-Cable), check clearance/routing
Notes
Tested on Bitaxe Gamma 602 black edition — other revisions may need adjusted mounting positions
Doesn't replace a proper main heatsink (Copperzilla etc.) — this targets the VR specifically, not the ASIC
