The Delta AUB0712HH is one of the 70mm fans Microsoft fitted to the Original Xbox. Twenty-plus years on, the sleeve bearings in these are the usual failure point — you’ll hear a ticking or grinding on cold start, or the fan will spin up slower and slower until it stops altogether. A stalled fan on a console that’s already running warm is how you cook a motherboard, so it’s worth fixing properly.
This is a tested pull, not new old stock. It spins freely and quietly at the time of testing.
What's in the box
- 1× Delta AUB0712HH 70 × 70 × 25 mm fan with its Xbox connector
No screws, no fan grille, no adapter.
Installation
Difficulty: Easy. Open the case (T20 Torx), unplug the old fan from the motherboard header, unclip it from the shroud, fit this one the same way round, plug in. No soldering required — provided your header matches the connector, see the verify note above. 15 minutes.
