Plug CPU fan into a Chassis Fan Header?
I recently purchased a Corsair H100i liquid CPU cooler, and have an ASUS Rampage III Formula mobo. The way that the motherboard fan headers and the corsair's one 3-pin cooling block connector are situated, it makes more sense for me to plug the cooling block fan back cable into the 'CHA_FAN' header in the middle of my motherboard.
Because of this however, one of my H100i's fans has to be plugged into the Rampage III's 'CPU_FAN' header. Is this ok? Or unsafe for voltages or something, I know CPU fans usually run around 2700rpm no?
Note that the cooling block's header is only 3 pin anyway, so I'm not losing any PWM capability here.
Here's a crudely painted picture of how I have my fans plugged in now:

You should keep the H100 fans plugged into the H100 pump/block. This allows the H100 to control its fan speed as required.
If you plug one of the h100 fans into the CPU_FAN header, its gonna run at full speed, unless you can change to CPU_FAN from PWM to Voltage in the bios. At full speed its going to be noisyReality is futile, you will be assimilated by (your) perception.
Golden Rule(s) for Fans: CHEAP + SILENT = NO PERFORMANCE ▼ CHEAP + PERFORMANCE = NOT SILENT ▼ SILENT + PERFORMANCE = NOT CHEAP
+Most SILENT Case Fans are not well suited for CPU-HS-Towers or Radiators
+Most SILENT Case Fans are not well suited for cases, especially if they have filters. (added by doyll on 23/04/2014)
