Drop Your VRM Temps — Dual 120mm Airflow for the Octaxe Gamma

The stock Thermalright AXP90-47 does its job on the ASIC, but your voltage regulators are still cooking. This dual 120mm fan shroud adapts two full-size 120mm fans down to the 90mm footprint of the AXP90, giving your Octaxe Gamma the airflow it actually needs.

Integrated cooling vents — inspired by our NQ Helix Shroud design — redirect a portion of incoming air directly over the VRMs. During testing, VRM temperatures dropped from 68°C to 60°C. That's real thermal headroom for sustained hashing or overclocking.

What's Included

1x Dual 120mm fan shroud (PLA, 3D printed)
Fans not included — we recommend Arctic P12 PWM fans for the best price-to-performance ratio

Key Features

Dual 120mm fan mount — doubles the airflow surface area vs. the stock 90mm fan
VRM cooling vents — channels air directly over voltage regulators, reducing temps by up to 8°C
Universal AXP90 fit — compatible with all Thermalright AXP90 models used on the Octaxe Gamma
3D printed PLA — lightweight, durable, available in multiple colors
Designed by Ix Tech — engineered in-house for the open-source Bitcoin mining community

Why It Matters

VRM thermals are the silent killer on compact mining boards. When voltage regulators overheat, you get throttling, reduced efficiency, and shortened component life. This shroud gives you a direct path to lower temps without modifying your board or swapping coolers.

Compatibility

Bitaxe Octaxe Gamma (all revisions)
Any Thermalright AXP90-series cooler (AXP90-X47, AXP90-X53, etc.)
Standard 120mm fans (25mm depth)

Recommended Fans

Arctic P12 PWM (120mm) — quiet, reliable, strong static pressure. Two required for full dual-fan configuration.
