Thermal Challenges: Older revisions of the Nerd QX++ (like Rev 5) have VRMs that run hotter than the newer Revision 6. High temperatures in this area often act as the primary limiting factor for both stability and fan speed. [00:29, 01:02] Active Cooling Solution: The upgrade involves adding a 40mm Noctua fan (12V) positioned directly over the VRMs. To mount it, a custom 3D-printed adapter from Xtech is used, which sandwiches between the main ASIC heatsink and its fan. [02:00, 05:11] Impact on Noise: By cooling the VRMs directly, the system's overall fan speed can drop from 83% to 52% while still maintaining a target temperature of 60°C. This reduces the noise level from 39.2 dBA to a much quieter 37.8 dBA, making it more suitable for an office environment. [06:49, 08:24] Impact on Temperature: Under 100% fan speed, the addition of the VRM fan drops the voltage regulator temperature by 7.5°C compared to the stock configuration, significantly improving the safety margin for the hardware. [07:12, 07:40] Installation Tips: The 3D-printed adapter pins slide into the main heatsink. Because the adapter adds thickness, the original metal fan clips may be harder to reattach; the video suggests using a screwdriver or manual pressure to force them into place. [03:49, 04:37] Compatibility: This specific VRM fan upgrade is most beneficial for Revision 5 or older units. While compatible with Revision 6, the newer models already feature improved native VRM cooling, making the extra fan less critical. [09:28, 09:43] #Bitcoin #Mining #NerdQAxe
