Dissatisfied With Current AIO - Buy a different one or go Air?

[Gmr_Chick]

Alright, so, my tower cooler adventures didn't pan out the way I'd hoped, so I just decided to purchase the 280mm variant of the Liquid Freezer II + 2 140mm Light Wings high speed PWM fans. Things are running great so far, but I'm a bit confused due to Gigabyte's less than ideal description of the fan headers in the online manual for the X670e Master. In the top right-ish corner of the board (close to the center VRM heatsink) are 3 fan headers labeled CPU_Fan, CPU_OPT and SYS_fan/Pump. Basically, the way they describe said headers in the manual, I don't know if I should connect the pump to the CPU_OPT header or the SYS_FAN_5-8PUMP, and the fans to the CPU_Fan and CPU_OPT headers. I'd like to be able to control both fans, but the pump I'm honestly just going to run at full speed.

I had to read over the manual. All the headers are apparently rated at the same 2A current rating. Guess it doesn't matter, although there may be differences in fan control (ie. available fan speed sources or speed limits).

Cpu_fan will respond to any bios setting about a failing fan or temp limit or whatever, cpu_opt (optional) won’t

Wow, I didn't even know that. Thanks for that handy tidbit of info!

I believe that the manual state that one should enable PWM in bios so please do that as well - if new version of Gigabyte Bios is equal to last gen there should be a way to save your fan profiles with the bios settings in files so you can test settings
