Many of the chips inside a typical PC generate a mete out of heat and require some frame of springy cooling to remain stable. Powerful recent hardware like Nvidia's GeForce RTX 3000-series graphics cards and AMD's Ryzen 5000 processors demand steady more hot up dissipation.
System builders usually rely on heatsinks and fans to manage the heat within a Microcomputer. If you're upgrading or building a new PC—or your PC is overheating—you may need to install new or additive fans.
Here's how to identify when you need to replace a fan you bet to do it yourself.
Identifying faulty fans
Often, a fan volition start to emit fantastic detrition noises or vibrations in its concluding death throws. Sometimes there is no admonitory at totally, and a buff testament wordlessly fall to a stop.
Open up the computer's case, turn IT on, and look close to with a flashlight (simply try not to touch modality anything while the computer is on).
Thiago Trevisan/IDG This exhaust fan is mounted to the back of the example to vent warm air. Exhaust system fans put up besides personify mounted to the top of the type, while intake fans are usually mounted happening the front or sides.
Altogether but the lowest-power, passively cooled systems, you'll likely find at the least quaternity fans: an intake fan, an exhaust fan, a CPU cooling buff, and a superpowe supply unit (PSU) cooling sports fan.
The CPU and PSU will be mounted on their respective components, but case fans rump be set nigh anywhere. It's common to find intake fans toward the bottom of a system, usually at the front, where they can take in the coolest aerate. Exhaust fans for expelling warm air are commonly found at the back or elevation of a case.
If unity of the fans has stopped, check to make a point it's connected. If the fan is connected and still International Relations and Security Network't spinning, it will need to glucinium replaced.
What you take to know before installing a buff
The majority of cases and PCs sold nowadays will have unused fan locations available. Even if all your fans are working, there's a good chance you'll have room for leastwise one much.
Thiago Trevisan/IDG If all your system's fans are operative, thus far the arrangement runs hot or mentally ill, you may want to lend more fans. If your case can't take any more fans, OR is getting too loud, deliberate melted cooling. Our guides to setting up your PC's fans for maximum system chilling and how to William Tell which direction a PC fan blows can buoy likewise help with the process.
If you need to replace a fan, arrive at predictable you find a replacement with the correct size, and connector.
Choosing the right winnow
Cooling fans are available in a wide range of sizes and shapes (and colors), from bantam barrel-type fans sometimes used to cool chips, to large axial fans used in most power supplies.
The most general fan sizes fall in the 70mm to 140mm range, but fans as enceinte As 230mm are becoming more popular. Fans with a diameter of 120mm are typical in newer cases.
Look for one with a high air flow (measured in cubic feet per narrow, or CFM) and low noise point (measured in decibels, or dBA). This information will be on the package operating room on the product's information page.
Thiago Trevisan/IDG Fans vary in size up, speed, blade shape and color. Some fans true come with shapely-in LED lights, others are many performance centralized such American Samoa this Noctua Chromax fan.
Larger fans can usually spin at lower speeds and still move plenty of air without making much noise. Some manufacturers incorporate LED lighting into their fans atomic number 3 well.
Maintain convinced pressure
When adding fans to a system, maintaining positive pressure within the example can prevent dust from being sucked into whatever open holes or crevices. To maintain positive blackjack, you need to have a higher hyphenated CFM for the consumption fans than the exhaust fans.
Note: All but fans rich person small arrows embossed connected their frames that show the direction of air hang. When mounting, point the pointer towards the inwardly of the computer for intake, and the arrow towards the outside for exhaust.
Power connections
To the highest degree cooling fans will connect to a PC with a modular connexion of some sort. Red-brick systems will typically use 3-flag or 4-immobilise sacred fan headers, though standard MOLEX 4-pin peripheral connectors are also used.
From left to outside: A 3-pin connector, a 4-bowling pin connector and a MOLEX connective. Make up sure to check what type of fan connector you need ahead buying your fan.
The analog 3-fall and MOLEX connectors ply force to the fan to make it spin. Four-pin connectors are digitally controlled and Army of the Pure the system to alter fan speeds dynamically.
Many motherboards (and dedicated fan controllers) will feature an array of 3-PIN and/operating room 4-pin sports fan headers that are located at other locations around the card.
Installing a new fan
Note: Before you install any element in your PC, pull in sure the PC is powered off.
To remove a imperfect buff or install a new one, you'll need a Phillips head screwdriver.
If you're replacing a winnow, remove the old one by unscrewing it from the suit and unplugging the cable from the header (or MOLEX association). You can recycle the screws if your red-hot fan doesn't attach to any.
To mount a fan, hold it up to the mounting stance so that the holes for screws blood up with the holes in the case. While holding the fan in place with i hand, use four screws to batten down it in situ with the other hand.

If you just have pliant friction clips holding a fan in situ, simply United Nations-walkover the clips, remove the fan, and toss off the new one in its place.
Next, impound the fan to an inactive fan header. The headers are keyed to ensure a right connexion. Four-stick headers will work with 3-pin fans, but you won't have control over fan speeds.
Marco Chiappetta Quartet-immobilize fan connections allow your data processor to change the fan's speeding on-the-fly. Usually, a system will lower speed to reduce noise and gain speed when much cooling is needed.
Purchasing a fan controller will generate you additive fan headers. Alternatively, you can use of goods and services 3-pin/4-PIN to MOLEX adapters and connect the fans right to the PSU. (MOLEX connectors are keyed too.)
Thiago Trevisan/IDG MOLEX fan connectors are older and assume't offer any controls for the fan, merely they're easy to tie.
Cardinal final note: Route your fan (and former) cables victimization appropriate telegraph management operating room many zip-ties. This will ensure that cables don't run into the devotee as it spins, causing a noisy sound. Cables that come in contact with fans arse also stop the buff completely, or worse, damage the cable.
