Review on 💨 Ultra-Quiet BE QUIET! Pure Wings 2 92mm PWM Cooling Fan - BL038 for Efficient PC Cooling by Chun Chun ᠌

We are talking about the 92 mm model. I took a NAS WD My Cloud Mirror to cool the network drive. I put it on top of the case, connected it from the USB drive itself. Max. the temperature of the discs dropped from 51 degrees to 36. At the same time, it is not audible at all. At first I thought about installing a control circuit to turn on the fan only when the temperature rises, and then I decided that with a declared resource of 10 years and at low speeds (from 5 V supply), it will outlive the drive itself. Plugged it in and forgot about it.
