Project notes 2022-10-24 (POC PSU fan)

All my scrap fans are simple 2-wire power-feed 12V fans.

• 12V PC 140 mm from Apevia, a very plastic fan. The rated electrical current is 0.33A.
• 12V PSU 140 mm fan from Yate Loon Electronics/Corsair supply rated at 0.7A.

Initial tests rule out old PC fans due to lack of static pressure capability, but the PSU fan looks promising and starts spinning at 2.7V. The electrical current consumption of the latter was 0.46A at startup but throttled down to 210 mA when it's up and running. The Corsair PSU fan is a sturdy unit with metal blades.

 
The PSU top part metal cover width is 150 mm from the PSU chassis scrap pile. We can later fit some HEPA and active carbon filters there to absorb the bad stuff.
