Flex ATX Fan replacement noise test
Well.
Excuse the potato sound quality for a sound test.
Recorded with a phone, 10cm from the fan.
Clicks for reference, 10cm from the mic.
Default fan was quite noisy (up to 8500rpm from what the seller said).
The Noctua one can go 5000rpm.
Replaced the default FAN with a Noctua NF-A4x20 PWM.
Fan speed sync with CPU temp :
30°C : 40%
40°C : 60%
50°C : 100%
