Does the Fan Side Matter for Cpu Cooler
Wondering what the difference between all those fan headers connected your motherboard is? Admiration no longer.
Imagine this.
You'rhenium construction your PC, You birth your CPU, your tank, and the motherboard in your Microcomputer-Case.
All you need to do now is to plug that dinky connecter from your CPU Cooler into the Motherboard. You take the wire and attend ballyhoo it in.
And past you get a line this:

Which one practice you select? CPU_FAN or CPU_OPT?
What is C.P.U. FAN (CPU_FAN)?
CPU_FAN, stagnant for "CPU Lover", is the main header used by the motherboard, and the BIOS and any otherwise software (SpeedFan, HWMonitor, NZXT Cam River, etc), to gover and control the CPU's thermals dependant on the payload by controlling the fan(s) speed (if you'ray using some class of splitter).
Information technology is critical that you make sure to wa your CPU cooler buff into this header as most motherboards meriting the name would not appropriate you in addition the system otherwise.
Also, if the arrangement is already gushing somehow, information technology testament safely closed it cut down if it detects that the CPU has atomic number 102 tank or that the fans are nonfunctional and/OR not spinning (when they are supposed to).
What is Processor Choose (CPU_OPT)?
CPU_OPT, lasting for "CPU Optional", is mostly old when you have more one fan happening your tank/radiator and you need someplace to plug it in.
IT's basically CPU_FAN without the "non booting if nothing is connected thereto" role.
It terminate also be in use by some AIO/liquid cooling solutions as a power beginning for things corresponding water-chilling pumps and new things that might require power but is non all-important or big businessman-hungry enough to reroute power directly from the powerfulness supply.
SYS_FANS, CHA_FANS, etc

And spell we're at it, we power as well address these as well.
I'm sure you've already figured it out from the name. These are the headers you get in touch your case fans to and are meant for differentiating winnow-control.
They'Re same CPU_OPT, but non connected to the thermals of the CPU. Indeed you're discharge to tinker with them and gain or decrease them according to your GPU thermals, CPU thermals, Case thermals, or whatever you wish.
And there are a open miscellanea of such headers along modern motherboards—mostly focused on helping water chilling. Let's rejoice that the days of plugging in 20 different things to one or two headers are thankfully over.
In Summary
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 great deal of fans).
If you only have a 2 buff ice chest, for example, you sack just use CPU_FAN for incomparable fan and CPU_OPT for the other.
If you have a radiator with a large turn of fans OR just a large act of fans in the main, you hindquarters look into acquiring a fan divider / fan hub to accommodate them.
For good example, you can use something like that to plug whol three fans (or six if you throw fans on some sides) of a 360mm radiator to the CPU_FAN header.
Oregon you can clean get a Y splitter (2 female connectors, one male) and plug one of the fans into CPU_FAN and the other deuce 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.
FAQ
- Posterior I wa a fan hub into CPU_OPT or CPU_FAN?
- Yes. But I'd recommend you use CPU_OPT or a case fan header and keep CPU_FAN just for the CPU.
- And make foreordained that you're non powering much of fans from incomparable head. Headers can run blistering when there's a great deal of power going through them.
- Get one that takes in external ability from the power supply instead.
- Where do you secure PWM fans?
- If you need to enjoyment any of the PWM functionality, you want to plug the 4-pin PWM connector into another 4-pin header instead you will miss that functionality.
- If you need to enjoyment any of the PWM functionality, you want to plug the 4-pin PWM connector into another 4-pin header instead you will miss that functionality.
- Give the axe you punch a 4-oarlock fan into a 3-pin? And vise versa?
- Yep. 4-pin fans can also Be related to to your motherboard's 3-pin devotee headers just fine. But you have to keep in mind that when affined to a 3-pin fan coping, the fan will run at full speed unless your motherboard has voltage-based speed see.
- What is the difference betwixt DC and PWM fans, and which is better?
- Eh, it depends. DC is of age and has been used since the times of the dinosaurs. It has a 3-pin connector and it works well, but if you want more control o'er how fast your fan spins, you need PWM.
- PWM allows you to have finer moderate concluded your speeds and allows you to reliably go to lower speeds.
- Mostly any fan worth its weight in salt comes with a 4-pin PWM connector these days.
