Thank you for the answer! I know that's not a problem to have two fans on the same channel with the aquaero 5. The question was to have two different ones. I will probably go for two same fans for now. This is for the front intake of my corsair obsidian 750d. The upper fan is behind the hdd so I was thinking to use a static pressure fan. But I will first try with the two original fans that came with the case.

Hello, I plan to use an aquaero 5 pro. I will have one channel with only one fan, two channels with two same fans on each channel and ideally two different fans on the last channel. I will also connect a Laing DDC310 on a poweradjust 3. Is it possible to use two different fans on one channel (one Corsair AF140 and one Corsair SP140)? On which one should I read the RPM? Or is it better to buy another poweradjust to control those fans separatly? Thanks.
