In summary:
The pros:
- Silent
- Actual airflow acting on the PC's temperature
- The USB Hub rear replacing the port occupied by the cooler on the PC
- The possibility to use either the 4 small fans or the general, or 5
Les -
- Too right width of 17 ''
- Cold air flow towards you really unpleasant (surely more pleasant in summer)
(But this is perhaps the cleanest of all these devices, I do not know, it's my 1st)
