CPU fan - a fan on top of a computer processor. It helps pull and blow hot air off the processor, helping keep it cooler. Power supply fan - a fan located inside a power supply. The power supply fan blows hotter air out of the power supply and out of the computer.

What parts in a PC needs fans?
The CPU is the one that needs most of the cooling and then the GPU. Most builds have their components centralized and have the exhaust behind the PC and have the intake near the drive bay. Most of the heat will be aired out immediately and get replaced by cooler air from the front side of the case.
Why is the fan required for the computer?
The sole function of computer fans is to cool the system by drawing colder air from the outside into the computer chambers and components, mainly, the CPU. In some computers, you will find the fan as a component of its power supply where it is performing its cooling function.
Does the CPU have a fan?
A Central Processing Unit (CPU) is the main microchip in a computer, while a CPU fan is the dedicated fan that helps keep the processor cool. ... The CPU fan attaches to the heat sink, pulling air through the fins. By dissipating heat drawn into the heat sink, the fan indirectly cools the processor.
How many fans does a computer have?
It is always our recommendation that you buy cases with a minimum of 3 fans (or at least slots for adding them yourself) for gaming systems, not counting the power supply, CPU, and GPU fans. I know we say this about a lot of things (especially power supplies), but you really don't want to skimp on cooling.
What is the fan in a computer called?
A heat sink and fan (HSF) is an active cooling solution used to cool down integrated circuits in computer systems, commonly the central processing unit (CPU). As the name suggests, it is composed of a passive cooling unit (the heat sink) and a fan.
What is the function of cooling fan?
A cooling fan is a vital component in a car cooling system, that helps takes away all heat absorbed from the engine using coolant. All its work is done through the radiator by pushing or pulling air through the radiator.
Do Intel processors come with fans?
In general, the processors shipped with standard fan heatsink, but not for the ones listed below. Click each link to view the CPU specification. Click each link to view the CPU specification.
Does my PC need a fan controller?
You don't need a fan controller though, you can get a 3 or 4 pin fan splitter to connect two fans to a single fan header.
How should I set up my computer fans?
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.
Do more case fans help?
Upgrading your CPU fan is a start, but adding case fans can also be a big help. Since performance-enhancing memory and graphic cards generate a lot of heat, case fans can help increase airflow to your components by attaching to the front and back of your system.
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.
Where do 3-pin fan connectors go?
3-pin fans will plug directly into a 4-pin motherboard header without any additional adapters. 3-pin fans still have an RPM sensor on them, and most mainboards can still vary their speed based on temperature. 3-pin fans use simple voltage control for adjust the fan speed.
What is a fan header?
The CPU fan header is for the CPU heatsink fan (or fans) only. The system senses the presence of this during startup, and controls the RPMs to regulate air flow as necessary. Connect the rear exhaust fan directly to the PSU using the Molex connectors (and adapters). Let it run at full speed for max hot air exhaust.
