Clearly it is not a high-end product, but to the 4 fan my HDD to control cooling is sufficient total! However, if you ever want to adjust the speed as in some case fans for CPU / GPU, I recommend another product, because my lasting place would go to the Rätchen on the cookie.
To what is nice to have in the 3.5 "drive bay that has a function and is illuminated this fan controller 1A with asterisks.
The USB ports I can not say anything because I have not connected. (Have a big Multi Panel in 5 "and as much USB I need but then nciht on the front ...)
ESATA connected and functioning ... (as expected)
