Tesla V100/P40 180° Turbo Blower Adapter

A 3D-printed 180° adapter that mounts a 12032 sidestream fan onto an Nvidia

Tesla V100 (P40 also fits) with the fan intake bent 180°, so exhaust is

directed away from the board instead of blowing back into the GPU or the

neighbouring slot.

Based on "NVIDIA Tesla P40 fan adapter" by NePe0 (CC BY).

The original was designed for the P40, whose board-side connector did not

match the V100's, so the mount interface was rebuilt around the V100 (P40

still fits). A 180° intake bend was added to reverse the fan's airflow,

plus numerous other fixes throughout the design.

The part is a one-piece design with:

• A base mounting flange (3-hole straight pattern) for fixing the adapter

to the GPU board.

• A fan cavity (rotated 180°) that seats and retains the sidestream fan.

• Reinforcing ribs for stiffness while keeping the part lightweight.

Compatible fan (reference part):

12032 sidestream fan — 120×120×32 mm, double ball, 2-pin / 4-pin,

DC 5/12/24 V.

Fitment notes:

• Designed on the Tesla V100; the same mounting pattern fits the P40.

Verify the 3 flange holes against your specific board before printing.

• Mounting: 3× M3 screws (straight-line pattern on the base flange).

• Fan cavity and retention tabs assume the 12032 sidestream fan mounted at

180°; other fan sizes will need adjustment.
