My Cloud EX2 fan cooler

Fan cooler adaptor base for the Western Digital "My Cloud Ex2 Ultra".
Smart HDD temp indicator (without fan cooler powered): 50°C
Smart HDD temp indicator (with fan cooler powered at 80%): 32°C

Since I inserted a new 8TB hard drive into the NAS, the average temperature rose from 40°C to 50°C (for both drives, there was only a 4TB WD before), I wanted to design a cooling system.
The direction of the air is desired from the bottom to the top, introducing fresh intake air, which passes through electronics and discs, and is then expelled upwards (hot). This is also an already natural process, as hot air travels upwards.

For the project I used a "Noctua 5V PWM 80mm" fan which generates a high airflow while remaining silent (17db). I also provided a switch that allows you to have maximum power at 100% (the switch provides 5V direct) or at about 70% (the switch activates a 10ohm resistor in series with the fan, increasing silence and maintaining a good air flow) .

You need:

• nr. 4, M4x40 phillips counterhead screw

• nr. 4, M4 washer

• nr. 4, M4 locknut

• nr. 6, M2,5x10 phillips counterhead self-tapping screws

• switch button (www.amazon.it/dp/B07L96XY2X)

• 10omh resistor
