I built a new system last month: http://www.tomshardware.co.uk/answers/id-3346766/upgrade-cpu-motherboard.html#xtor=EPR-8809
Temperatures were not too bad but wanted to get some more airflow to my GPU so installed a bottom intake fan and whilst I was at it a top exhaust as well.
I have all my fans connected and working but I am having trouble controlling them, most are running at 100% all the time.
See below diagram of my setup:
All fans are 120mm, 2 exhaust fans run direct from PSU, 2 side fans are 2 pin connectors (ignore above diagram where it says all are 3 pin) and the other 2 fans (bottom & front intake) are 3 pin connectors. The 2 side fans are probably excessive and might not get used depending on temps, in which case I would just unplug them or ideally run them at a very low rpm.
I have 3 options on where to plug them in on my ASUS B250F Strix motherboard, CHA_FAN1, CHA_FAN2 & AIO pump. The CPU fan is obviously taking up the CPU_FAN slot and I am not sure if the CPU_OPT is suitable.
I have tried controlling the fans using QFAN in the bios, tried PWM and DC mode, tested all the options like SILENT and it didn't make any difference.
I installed asus AI Suite 3 so I could try Fan Xpert4, after running the fan tuning it only recognises the cpu and the fans plugged into CHA_FAN2 but they have min RPM of 1,356 and a max of 1,362 so I have no control over that anyway! I have tried plugging into the AIO pump instead but it made no difference. So CHA_FAN1(2 pin cables) does not get recognised at all. When I try changing the settings in Fan Xpert of CHA_FAN2 to silent or full speed it only affects the speed of the CPU fan!
I am not using the most up to date BIOS as until this point I have had no issues with my system so didn't think it was worth the risk, I am using 0310 and ASUS EZ update is suggesting 0312. Should I update the bios?
I don't want to buy all new 4 pin fans, are the amount of pins the problem? I know 4 pins use PWM to pulse the speed but I have read that 3 pin/molex are still controllable through most motherboards by adjusting voltage? Do I need to buy a fan controller?
Any advice welcome, thank you in advance.
