The Bitaxe DualSink is a dual-heatsink cooling upgrade for the Bitaxe Gamma 601, designed to dramatically improve heat dissipation for stable performance during long mining sessions or overclocking. It uses a thermal pad on the bottom heatsink, high-performance thermal paste on the ASIC, and reuses the original fan for efficient, quiet cooling.

📦 Bitaxe DualSink – Product Description & Assembly Guide

Overview
The Bitaxe DualSink is a dual-heatsink cooling upgrade for the Bitaxe Gamma 601, designed to improve heat dissipation and maintain stable performance during extended mining sessions or overclocking.

Requirements

• 4× M2.5 × 35 mm hex screws
• 2× Heat sinks (labeled B for bottom, T for top)
• 1× 40 × 40 × 2 mm thermal pad
• High-performance thermal paste

Assembly Steps

1. Prepare the Bitaxe Gamma 601
   • Power off and disconnect your unit.
   • Remove any existing heatsink or cooling hardware.
2. Clean the ASIC Surface
   • Gently clean the top of the ASIC chip with isopropyl alcohol and a lint-free cloth.
   • Remove all old thermal paste and debris to ensure a smooth, clean surface.
3. Install the Bottom Heatsink (B)
   • Identify the heatsink labeled B (bottom).
   • Place the 40 × 40 × 2 mm thermal pad directly on its surface.
   • Position the bottom heatsink so the thermal pad aligns under the ASIC chip area on the PCB.
   • Ensure the F marking faces toward the LCD.
4. Apply Thermal Paste
   • Apply a thin, even layer of high-performance thermal paste to the cleaned ASIC chip.
   • Avoid applying too much—just enough to fill microscopic gaps.
5. Position the Top Heatsink (T)
   • Identify the heatsink labeled T (top).
   • Align it over the ASIC chip so its base makes full contact with the thermal paste.
   • Ensure the F marking faces toward the LCD.
6. Secure the Assembly
   • Insert the M2.5 × 35 mm hex screws through the mounting holes.
   • Tighten evenly until the mount is flush—do not overtighten.
7. Reinstall the Fan
   • Reinstall your original fan if the cable length allows.
   • To mount securely, lightly bend the corner fin of the heatsink to give the fan screws a spot to grip.
8. Final Check
   • Verify that both heatsinks and the fan are firmly in place.
   • Ensure airflow from your fan is unobstructed.

Tips for Best Performance

• Use a PWM-controlled fan for quiet, efficient cooling.
• Periodically clean dust from heatsink fins.
• Replace the thermal pad and thermal paste during maintenance for peak performance.
