This is a best seller Rhéobus fans in management matters to me. It manages up to 5 fans simultaneously see 2 per channel (A PWM molex plug and socket) So finally up to 10 fans. Be careful though to the power delivered by each channel (10 watt) The touch is well done, unfortunately when the computer is turn off the display you see the separation lines. It's a small detail not annoying to me. The lengths of the cables is incredible (See too?). Finally, a very good Rhéobus for the price.
