ReadyNAS Pro - Replace CPU Fan
The 80mm CPU fan on my ReadyNAS Pro Business NAS is starting to go. This is an early model that arrived with the CPU three pin header connected to the daughter board, as opposed to the main board. ...
Note the CPU fan wire is attached to the daughter board header toward the rear of the NAS. The rear 120mm case fan attaches to the other header on the daughter board.
After taking the photo the case was vacuumed out the rear 120mm case fan was put back in the case.
The Seasonic PSU was also replaced. This original PSU is in the photo.

I have replaced both CPU fan and system fan in a ReadyNAS Pro Business Edition:
Replaced CPU fan:
From: Crown 80 x 80 x 15mm AGE08015B12V, 4-wire
To: Cooler Master 80 x 80 x 15mm R4-SPS-20AK-GP, 3-wire
3 versus 4 wire: http://www.intel.com/support/motherboards/desktop/sb/cs-012074.htm
Replaced system fan:
From: Crown 120 x 120 x 25mm AGE120025B12M, 3-wire
To: Noctua 120 x 120 x 25mm NF-P12, 3-wire
Both fans work as expected, and are quieter than factory equiped fans. However, I prefer a bit more airflow because cooler = better life. Also found the CPU heatsink needed additional thermal paste because the factory installed bonding was marginal (use good silver thermal paste).
