Which way do you install a case fan?

When mounting case fans, air flows across the open side towards the side with the protective grille, like so: So the open side of the fan should face outside the case for intake fans on the front or the bottom, and it should face inside the case for fans on the rear or top.

Where do case fans plug into motherboard?

Connecting Fans to a Motherboard

The best way to connect a case fan is to the motherboard, as this allows you to control the speed of your fan inside the motherboard BIOS. But that’s if your fan has a 4 pin cable, as fans with 3 pin cables don’t have this capability.

How do I connect more case fans?

Should I connect case fans to motherboard or power supply?

Connecting Fans to the mobo is always preferable, you should only connect them to the PSU if your mobo runs out of connectors.

Is it bad to connect fan to PSU?

Fans plugged into the PSU will run at full speed. Generally, you won’t get any control over the fan speed using a three pin header. PWM fans require 4 pins in order to control the fan speed. The best way to control fans speeds using three pin headers is to get a fan controller.

Can you plug case fans into the PSU?

Some fans come with 4 pin Molex connectors which you can plug straight into your PSU. Although you could connect them to the PSU with a molex adapter, they‘ll run full speed all the time. If you want speed control on them, you may want to consider getting a splitter or controller that connects to your motherboard.

What do case fans plug into?

Power connections

Most cooling fans will connect to a PC with a standard connector of some sort. Modern systems will typically use 3-pin or 4-pin dedicated fan headers, though standard MOLEX 4-pin peripheral connectors are also used. From left to right: A 3-pin connector, a 4-pin connector and a MOLEX connector.

Do Case fans plug into motherboard?

To connect your fans to your motherboard, you’ll need to look for the appropriate headers, such as CHA_FAN above (chassis fan) or SYS_FAN (system fan). Most of your fans will have either three or four-pin connectors, so you’ll need to look for the corresponding headers on your motherboard.

How many fans can you connect to PSU?

Sure you can. Many fans bring an adapter (or you can buy one) to convert from the three-pin connector most fans come with to a molex connector you can plug to one of themolex connectors of your pc’s power supply. With this one you can connect up to four fans.

Can you plug a 3 pin fan into a 4 pin?

Apparently a 3–pin fan can plug directly into a 4–pin socket. Two of the pins provide power to the fan, the 3rd provides an RPM pulse to the motherboard to read the speed. The 4th pin is for PWM speed control. If you plug a 4 pin fan into a 3 pin socket, the fan speed will be controlled by voltage and it’ll still work.

Do Fan splitters reduce speed?

the splitter shouldn’t change the speed, unless you overload the header. that is why it is often better not to use splitters, because it may even damage you motherboard if you put too many fans on it, and usually you don’t need more fans than you have headers.

Can I plug a case fan into m 2 fan?

You can plug the case fan into the M. 2 fan header, but it will run at a fixed speed, which you can set in the BIOS.

Can I plug a case fan into AiO pump?

Yes you can, there’s not much difference in motors for AiO pump and any fan.

Are fan splitters bad?

They’re safe. The reason why the fan connects to the motherboard is so that the motherboard can tell the fan when to ramp up its speed (they don’t run at full blast unless they need to).

Does System fan order matter?

it depends on which fan.. the fan on the cpu cooler NEEDS to be connected to CPU FAN, only way motherboard can detect if that fan stops working. Other fans it really doesn’t matter Yes CPU fan needs to be in a CPU fan header. Then just plug other fans into the closest headers in the motherboard.

What is the difference between CPU fan and pump fan?

CPU fan can normally be set to scale with CPU use. SYS fans are either constant, or can be set to scale with overall system temperature (or sometimes CPU temp). Pump fans are normally 100% all the time to properly power the WC pump.

Can I connect CPU fan to system fan?

Yes! Perfectly fine! Another option is to connect the second fan directly to the PSU using a Molex connector.

How do I control my fan system?

Can HWmonitor control fans?

HWmonitor can‘t really control fans, thats why PWM percentage is at 0. You can control fans from BIOS, using motherboards own software or by using 3rd party software Argus Monitor.

Where do I control my fan speed?

The BIOS menu is the place to go to adjust the fan speed.
