Nice find, but please don't blow compressed air into a fan without blocking its rotation. It will induce currents and can cause damage to your mainboard.

- jmiserez 8y agoSeems like a problem a simple diode would fix. Is this really an issue?
- LeonM 8y agoMost motherboards (but not all) have basic protection for this, so it's quite unlikely that you break your motherboard electronically that way. That said, blowing compressed air at a fan will spin the fan much faster than what it was designed for. So you still risk breaking the fan mechanically. Always hold the fan when blowing compressed air at it.
- leonardmh 7y agoAlmost certainly not an issue on Apple hardware. Maybe on discount motherboards.
- yulaow 8y agoEven more important: do not blow air in the opposite direction of the one the fan is made to rotate. If you are unlucky you'll damage it, if you are very unlucky it will stop working enterely. Source: I broke a lot of them
- sundvor 8y agoI'm pretty sure I managed to blow dust into the screen of an XPS 12.. So yeah, it pays to exercise caution.
- appleflaxen 8y agothat's a really good point. thank you for pointing it out. I've cleaned many a fan, and have never thought about this.
