Are the fans all really running that fast ? Unlike the fans on NETGEAR ReadyNAS 102 and 104 which are Protechnic MGT9212YB-025 92mmx92mm running at 3200 RPM max, the three fans in the RN2120 are Protechnic MGT4012XB-O20, i.e. 40mmx40mm running at 8000 RPM max. At least, this is the max RPM value I found on their website (Search Products on left side of http://www.protechnic-us.com/en/) for both devices. When pushing one a bit, here is the max rotation speed I get: root@thin:/sys/bus/i2c/drivers/g762/0-003e# echo 9000 > fan1_target ; \ sleep 5 ; cat fan1_input 8057 which AFAICT validates current settings for G762 and fan combination. Did I miss something?

No, I don't.
