I bought this product for controlling fans and significantly reduce noise in the tower. Overall it works well Rhéobus but seems a bit fragile and it is not a true 5'1 / 4. If you press too hard on the dial, it has a tendency to move and get sideways into the slot, which is not really aesthetic. Then the documentation is very slight and not very clear, in fact, when recording the temperature limit is not exceeded, so do not look for a button that would store the selected digit. Similarly, fan speed limit is set at 40% of their ability, we can not go below. Finally, the unit I received, even if, ultimately, is quite pretty, had the disadvantage of having a switch that did not work, as well taking 3-pin molex that, making Rhéobus that can rotate only 4 fans instead of 5. I realize it once assembly is complete and for the price I have not had the courage to take everything apart, return the product, wait a indeterminate time ... Now we must see what will in the long term.
