Pros: Manual + PWM control for non PWM fans, 30 watts per channel and individual channel mode control. Price!
You can use splitters to tie multiple fans together on one channel, or make your own cabling. The kit comes with two usable fan cables/extensions that allow rpm reading. I ended up making the other four as I have three fans each on two channels then two fans on a third channel while the others have just one fan attached. All together that's 6 GT AP-15s, 1 x 200mm Xigmatek, 1 x 140mm Xigmatek, 2 x 120mm Xigmatek and a 120mm x 12mm Scythe Slipstream. There's still room to add more if it ever becomes necessary.
If you're looking to tame your fans a bit and don't want to spend $60.00- $75.00 on digital read outs with only 10 watts, this is a very deluxe unit. No regrets here! Feel free to PM in I can ever assist anyone.
Just an FYI about connecting the yellow rpm wire. If you use multiple fans on one channel be sure to only have one yellow wire connected to the control unit. The other fans on that channel should have the yellow removed from the connection so when monitoring the rpm you have an actuate reading. More than one fans yellow wire can cause issues to read out.
Not really a con for me as I was counting on having to make my own cables due to the number of fans I want to control, but don't think you can install this system with only the included hardware (wire harnesses) if you have multiple fan headers that can read rpm and wish to use them. My CHIV has 8 fan headers and I use most of them to monitor rpms. Others with less connections may be ok without having to make any custom cables.It's not a tough job and does require a little thought but most should have no problems with the install.
Red and Black wire for power, Yellow wire is for rpm and the Blue wire is for PWM.
I took a lot of time to research before purchasing this unit and feel it paid off real well. Very happy and will recommend to all that ask!
