Given the description of the CPU Fan Type Setting option, it should be left on Auto except when using a stock Skylake cooler with a Nidec fan.
When set to Auto, the four pin PWM fan speed control still works fine. The names of the settings of this option are unfortunate, they should be Auto and Nidec/Stock Cooler.
Yes, this option affects both the CPU_FAN1 and CPU_FAN2 connectors.
But I have used both three pin and four pin fans on the CPU_FAN2 connector, and they worked fine, no speed problems, no triple POST.
These headers are said to detect a three or four pin fan, its a feature called Smart Fan Speed Control.
Is there a reason you feel the need to use the "4 Pin" setting, given what it does to your cold startup? I've tried both settings, with UEFI 3.00, and while it never causes the triple POST failure, if set to 4 Pin it breaks three pin fan speed control on the CPU_FAN2 connector. Three pin fans seem to run at full speed regardless of the CPU_FAN2 speed profile selected. That is actually better for Corsair pumps! Read on.
Ahh, Corsair, your instructions can be so terrible... "... connect the dual fan connector to any four pin fan header on the board..." Image may be NSFW.

The same for the three pin pump connector. Image may be NSFW.
Clik here to view. No mention of speed adjustment for either the fans or pump. Image may be NSFW.

I've used Corsair AIO coolers. The pumps are meant to run as full speed ALL THE TIME! How does that happen on most mother board fan headers that have fan speed control? Unless they are set to Full On? Image may be NSFW.

The Power Fan header on this board can be used with the Corsair pump, no speed control, full power all the time.
I ran my Corsair pumps with a four pin molex to three pin fan adapter, a common extra included with fans.
I suggest trying either of the two ideas above for the pump, and see what happens.
