What is a computer fan header?
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).
Can you plug a fan into any header?
You can plug practically any fan in any place on MB, they will just be controlled different ways. CPU_OPT fan will be controlled by CPU temperature and AiO pump may not be controlled at all.
What are fan headers used for?
Yes, you can plug a 3-pin into 4-pin Motherboard fan connectors provide fans the small amounts of power they need to keep spinning and, in some cases, offer user control of fan speed. Here’s everything you need to know about motherboard fan connectors.
Can you plug a normal fan into a CPU fan header?
Yes, you can connect case fans to CPU_fan headers. Or you can use fan splitters to connect two case fans to a single chassis_fan header.
Why do PC fans have 4 wires?
The 4-wire fans have a PWM input, which is used to control the speed of the fan. Instead of switching the power to the entire fan on and off, only the power to the drive coils is switched. The PWM signal drives the fan directly; the drive FET is integrated inside the fan.
Can I plug case fan into LED header?
No you can’t, pinout isn’t compatible. Son of a gun! Can I buy an LED case fan and use it there…?
Can I plug fan into RGB header?
Yeah in order to plug in more than one fan you’d need a fan splitter or a hub. The RGB cables and fan cables run separate from each other. So you would need to plug the RGB cables into your controller or your motherboard.
Are all PC fan headers the same?
A mobo normally has two types of fan headers, but there are sub-types. It always has at least one CPU_FAN header to control the fan (or whatever) cooling the CPU chip. Almost always it uses ONLY the temperature sensor built into the CPU chip itself by its maker and sent out to the mobo on one chip pin.
What is the difference between CPU fan and system fan?
The difference between the CPU fan and the system fan is that the former is the one attached to the heatsink of the processor, and the latter is generally on one of the sides of the case to exhaust hot air.
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.
What’s the difference between CPU fan and CPU opt?
The crucial difference between a CPU OPT header and a CPU FAN is that CPU OPT headers do not prevent your PC from booting or automatically shut it down if they do not detect a functioning CPU cooler; they therefore lack an important safeguard compared to CPU FAN headers when it comes to CPU cooling.
How many pins does a CPU fan header have?
CPU fans like the one on the Intel stock heatsink or the ones that normally come with aftermarket CPU heatsinks usually have 4 pin headers, and should be plugged into designated CPU fan connectors located at the top of the motherboard. Usually motherboards should have at least 1-2 4 pin connectors for the CPU,…
What is AIO pump header?
AIO pump header or just a normal cpu_fan. The pump headers normally run at full speed all the time to keep the water circulating at a constant rate. The pumps are fairly quiet it is best to not run them at lower speeds. Temperature can be regulated by the fan speeds and a custom fan curve if you desire.
What is fan hub?
Fan hub is the mechanical connection between the radiator fan and its point of attachment. Category: Automotive Engineering .
