Arrow Maximum Fan Currents and General Setup Requirements

It's quite hard to find out what the maximum fan currents are so I created a table. For completeness I also included the latest firmware versions and which speed is reported to the CPU_FAN header.

Notes:
  1. Asetek coolers have a single fan controller which both fans use and only one fan speed is reported.
  2. For all CPU_FAN powered coolers you need to disable CPU_FAN header control in the BIOS so that the cooler gets the constant +12 volts that it needs. Typically set the mode to PWM and full speed, 100% or similar. The actual setting varies from motherboard to motherboard.
  3. The H115i + H110iGTX manuals are incorrect as both coolers are SATA powered rather than being powered form the motherboard CPU_FAN header.
Corsair, please will you correct any errors and make this sticky?

  3. This was bad for the node to say the least.
  4. The Commander Mini, on the other hand, has full hardware voltage control integrated into the fan headers.
  5. I use a Commander Mini in my home system, it's a major upgrade on the original Commander and Cooling Nodes.

This is referring to the H110iGT (CoolIT) vs H110iGTX (Asetek)

Idea Pump Speed ÷ 2

I expect the H115i + H100iV2 + H80iV2 report the Pump Speed ÷ 2 to the CPU_FAN header. Please let me know if you think this is not the situation or if you know where Corsair specify what this is. AFAIK Corsair do not specify this which I feel is rather poor.

Arrow CLCP Information Added

I have added the CLCP information and still feel Corsair should make this thread sticky or post a similar sticky thread.
