First off I should apologize if this has been asked in a different thread. I've searched the web far and wide. My search has not yet yielded a solid solution for my endless troubles, so here it goes.

I am currently running the Asus z87-a motherboard and I am quite pleased with it. To cool my intel i5-4670K processor I have a CoolerMaster Seidon 120V. The Seidon 120V pump is powered by a simple 3-pin connector and the included 120mm fan is driven by a PWM controllable 4-pin connector.
- The question there for is: To insure my pump and fan run at the optimal speed while keeping the noise-level to a minimum, how should these two connector be plugged into my motherboard?
I have 4x CHA_FAN, 1x CPU_FAN and 1x CPU_OPT header.

Thank you in advance!
 
Solution
plug the pump into a CHA_FAN connector since it doesn't have the 4th pin for PWM, and plug the fan into the CPU_FAN connector (so the fan speed will adjust upwards when your CPU gets hotter).
Plug the 4 pin fan into the CPU_Fan. Plug the 3pin pump into any 3pin on the motherboard.

Then check bios/fan controller software to make sure you don't have this connection set to something other than 100%.
Usually by default these connections pump out 12 volts. Sometimes you can use bios settings or fan control software to turn them down to 50% (about 7 volts).

Edit: Some pumps will are meant to be able to run at 7volts at a reduced speed.
