🚀 Finally solve the VRM temperature issue on your liquid-cooled NerdQaxe++!

If you’ve liquid-cooled your NerdQaxe++ (or NerdQaxe+ Rev 6.1) (Snowman, Karpuz Mod, or other liquid block), you know that the MOSFETs/VRMs quickly become the weak point: they heat up significantly and limit overclocking or long-term stability.

I designed this 3D Printed mount specifically to install a 40×40 mm fan directly above and as close as possible to the VRMs, without touching the waterblock or disassembling the LILYGO T-Display S3 screen

Highlights:

  • Identical mounting to the original NerdQaxe holes (same stock spacing).
  • 40×40 fan ultra-close to VRMs → direct and efficient cooling.
  • Two versions available in the pack:
    • Version with M3 inserts (provided by default – the cleanest and strongest).
    • Version with direct holes (for classic screws, without inserts).

Recommended printing (tested and validated):

  • Material : PETG (mandatory to resist heat near VRMs)
  • Infill : 100%
  • Supports : none
  • No brim needed
  • Printed flat as shown in photos → strong and no warping.

Observed results: VRM temperature drops significantly → better efficiency, less throttling, ability to overclock higher and longer. Perfect for 24/7 solo Bitcoin mining sessions!

 

Compatibility:

  • NerdQaxe++ (all liquid-cooled revisions)
  • Standard 40×40 fans (Noctua NF-A4x10, Sunon, Delta, etc.)
  • Works with large waterblocks as well as small AIO radiators

If you're liquid cooling your NerdQaxe, this small part really makes a difference. Print it, test it, and come back to tell me your before/after temperatures! 😊

Boost Me (for free)

If this mount helps you drop a few degrees on your VRMs and improve the stability of your NerdQaxe, don't hesitate to give it a little Boost! It helps me get the model higher in search results and encourages me to keep creating other useful mods for the community.
Thanks in advance to all and happy mining! đŸ”„
