What Is a Cha Fan [Best Answer]


Well, the CPU fan is for the CPU fan, whereas the chassis fan is for the fans on the case, also known as the chassis.

The ext fan header, which stands for extension, is used to attach a different fan that will be controlled in the same way as the fan header it is an extension of.

No, there is no need to enable fan control for the PCH fan or any other OPT fans unless you want to be able to control their speeds using the bios.

Are Cha Fans Case Fans

Well, the CPU fan is for the CPU fan, whereas the chassis fan is for the fans on the case, also known as the chassis.

Is PWM the Same as a Cha Fan

I’d guess CHA_FAN is for chassis, which would be a case fan; PWM is referring to the CPU fan; PWM automatically changes the fan speed based on how hot the CPU is.

an aio pump can be plugged into a fan header and it will function flawlessly

Can You Plug a 3 Pin Fan Into a 4 Pin

In most cases, a 3-pin case fan will run unregulated at a fixed speed when connected to a 4-pin motherboard connector; however, some newer boards allow the fan speed to be adjusted by voltage. The fourth pin is simply left blank in this configuration.

Can I Plug Cpu Fan Into System Fan

  • Theoretically, yes.
  • Since they all have 3 or 4 pins, you should be okay.
  • You will need to adjust the fan curve (if you can), as kschendel suggested, but aside from that, you should be okay.

Can You Plug Aio Pump Into Cpu Fan

An AIO pump can be plugged into a fan header, and it will function flawlessly.

Is PWM Better Than Dc

  • Consider the duty cycles of PWM fans.
  • When a fan is on a 40% duty cycle, it’s only using electrical power 40% of the time.
  • In contrast, the DC fans, if anything, will use a slightly lower voltage.
  • PWM fans are generally more efficient than DC fans and use less power.

What Is VRM Fan

Ask any PC enthusiast and they’ll gladly tell you that a VRM’s role is to provide a clean and efficient power supply to the CPU or GPU. VRM stands for voltage regulator module, and in this case, the term specifically points to an array of components on a motherboard.

What Does PCH Fan Mean

No, there is no need to enable fan control for the PCH fan or any other OPT fans unless you want to be able to control their speeds using the bios. The PCH fan is the small fan on the board’s chipset.

What Is Ext Fan

The ext fan header, which stands for extension, is used to attach a different fan that will be controlled in the same way as the fan header it is an extension of.

Why Are PWM Fans Better

The chassis and CPU temperature are the two factors that affect the speed of the cooling fans, and the speed variation is within 30-100% of the rated speed, with the PWM technique and the minimum speed achieved by PWM fans being much lower than DC fans.
