Can Cpu_opt be used for a case fan?

Can I Use CPU OPT for Case Fan? CPU fan header, CPU OPT, and SYS fan header, if all of them are 4 pin fan headers, the motherboard, and in turn the BIOS and the OS, can control the fans’ speed. therefore, theoretically, you can connect the case fan or one of the case fans to the CPU OPT without a problem.

Can I use a fan header for a case fan?

If you want to connect fans from your CPU cooler or radiator, use the CPU_FAN header (With a splitter/hub if you have a lot of fans). You can do the same thing with your case fans as well. Case fan into hub/splitter, hub/splitter into case fan header.

Can you use AIO pump header for fan?

Can you plug an AIO pump into a fan header? Yes. It will work perfectly fine.

Can you use m 2 fan header for case fan?

Neither M. 2 nor the FanConnect headers should be used for case fans or CPU cooling. What you NEED to do is get a fan hub. Whether PWM 4 pin or 3 pin voltage controlled depends on the type of fans you have.

Does it matter which system fan header I use?

The only one that makes a difference is the cpu fan. Make sure that one is plugged into the “cpu fan” header on the m/b. Other than that, the header used makes no difference.

Do I have to use the CPU fan header?

CPU cooling fans should ALWAYS be plugged into the header that is specifically labeled “CPU Fan” and not “CPU Optional” or any other header. The reason for this is that the CPU fan header reads temperatures directly from the CPU and scales the fan speed accordingly.

Can you connect CPU fan to pump fan?

Connect one adapter to CPU Fan 1 and the other adapter to CPU Fan 2. PUMP: Its recommended that the pump be connected to an alternative fan header on the motherboard such as System Fan 1, Chassis_Fan 1, or for newer motherboards a dedicated pump header.

Can I use a fan header splitter?

You will be safe using a fan splitter as long as you the fans you are connecting does not draw more current than the motherboard header provides.

What is CHA_FAN2?

CHA_FAN2 is a white 3pin plug which is located near the CPU.

Should Case fans be PWM or DC?

Pulse width modulation (PWM) fans are DC fans with an extra wire for PWM….PWM Fans or 4-Pin Fans.

DC Fan	PWM Fan
Speed can be lowered up to 40\% of the rated speed	The lowest speed can be less than 20\% of the rated speed
Possibility of motor stalling below the minimum threshold voltage	No chance of motor stalling

Can I use the CPU opt header to run a case fan?

Sounds like using the CPU OPT header to run a case fan would not be a good idea since the CPU FAN usually runs at a higher voltage than the case fans on the Chassis header and the fans I am using are particularly loud and I want to keep them to as low a voltage as possible.

What is the difference betweensys fan and CPU opt?

Sys fan means system fan,which indicates the fan screwed to the chassis,bringing air in/out of the vents on the case. Cpu opt is when you go watercooling,where you may have two fans,like dual radiator,and need to connect it to a fan header.

What is @CPU_fan and what does it do?

CPU_FAN, standing for “CPU Fan”, is the main header used by the motherboard, and the BIOS and any other software (SpeedFan, HWMonitor, NZXT CAM, etc), to regulate and control the CPU’s thermals depending on the load by controlling the fan (s) speed (if you’re using some sort of splitter).

How do I split a CPU fan in half?

Or you can just get a Y splitter (two female connectors, one male) and plug one of the fans into CPU_FAN and the other two into the splitter, and then that into CPU_OPT. You can do the same thing with your case fans as well. Case fan into hub/splitter, hub/splitter into case fan header.
