The control of each fan is super controlled, personally I've never been so cold Lüftzüge in a computer environment.
What the incorporation of shares in terms etc., I can only agree with the other people. Well done to the rails and a simple installation.
The problem with the difficult to open pages, so I have not experienced now. Was easy for me.
The only negative factor was personal to me that you just had just reached the offsets of the power supply down, the cord under slight tension their goal. But this should be no problem with the current power supplies.
