The motherboard’s fan headers offer the enthusiasts with the small quantities of strength they want to maintain spinning and, in a few cases, offer the consumer fan velocity control. Here’s the whole thing you want to understand approximately motherboard fan connectors.
If you’ve got ever assembled a laptop or constructed a PC yourself. You might also additionally have observed that many PC fan manufacturers frequently have three-pin or four-pin CPU connectors. Because there are a few variations among three-pin and four-pin enthusiasts. I will help you understand that and which one is higher in comparison to 3pin and 4pin fan connectors.
Due to the improved velocity and strength intake of processors, different laptop additives could produce a huge quantity of warmth as a facet impact of everyday operation.
For this, enthusiasts are used to manipulating the temperature to make sure reliability, electricity performance, and velocity comments. And to save you instability and harm a good way to shorten the PC’s lifespan, is the fan controls the rotational velocity and voltage supply.
What is a motherboard fan connector?
A motherboard fan connector is a small 3- or four-pin connector placed at the motherboard. The fan could have a hard and fast cable (included) a good way to hook up with the connector at the motherboard.
The motherboard fan connector is a Molex KK connector. It is a part of its own circle of relatives of laptop strength connectors designed via way of means of the Molex Connector Company, which additionally created different inner laptop strength connectors, which includes the bigger four-pin Molex utilized by older PC controllers, the difficult drive, and the motherboard strength connector.
Today the call Molex is not often used. Motherboard manuals most customarily use the terms “SYSFAN” and “CPU FAN” whilst relating to those connectors. SYSFAN and CPU FAN are technically identical connectors, however, SYSFAN is used to attach the PC case enthusiasts, at the same time as CPU FAN is used for the fan related to the CPU heatsink. If you have by no means used those connections before, do not worry. They are clean to apply and nearly not possible to attach incorrectly. The toughest time you may have is getting your arms and palms withinside the region in which they want to be.
How does a motherboard fan connector work?
Power is the activity of a motherboard fan connector.
A 3-pin motherboard fan connector generally has black, purple, and yellow wires at the fan facet of the PC, however, those hues can range via way of means of producer and from time to time even model. The black cord is grounded, the purple cord is strong, and the yellow cord affords a cutting-edge fan velocity analysis to the PC.
A four-pin motherboard fan connector allows a characteristic known as pulse width modulation (PWM). PWM can activate and rancid extraordinarily quickly. This controls the rate of the fan.
If a fan is about to run at 50% of its most velocity, the PWM will cycle on and off so the fan simplest gets strength 1/2 of the time. This is going on too speedy to notice, so the fan seems to be strolling at a steady velocity of 50% of its everyday velocity.
The motherboard fan connector can even encompass a plastic manual that extends from the connector subsequent to the pins. This suits right into a notch inside the PC’s fan connector. The manual guarantees that the connector cannot be reversed.
Three-pin fan
The three-pin fan connector has 3 indicators (relying on the wide variety of wires): the primary cord is for strength (four-12 volts), the second one is for ground, and the 0.33 cord is for a tach sign (sensor velocity sensor). ) this sensor controls the rate and overall performance of the fan.
A techo metric sign adjusts the extent of strength carried out to the motor via way of means of transmitting the rate of rotation of the fan wheel to a nominal voltage between five and 12 volts. In this way, the rate of the fan is normally managed via way of means of growing or lowering the voltage throughout the strength cable.
Four pin fan
Four-pin fan headers are usually observed on contemporary-day motherboards. The four-pin fan connector is barely unique from the three-pin connector which additionally works the identical, however, the extra 4th cord is PWM (Pulse Width Modulation) that’s used to manipulate the charging strength and rotation velocity of the fan. fan wheel.
The PWM cable may be very critical for correct CPU cooling in contemporary-day PC towers. It adjusts the rpm the usage of a PWM sign and concurrently affords comments from the tachometer. In different words, the longer the voltage is carried out to the fan motor coils, the better the rate of rotation, and vice versa.
Difference between three and four-pin enthusiasts
There are 4 variations among three-pin and four-pin fan connectors. Let’s know:
1. PWM (Pulse Width Modulation)
PWM enthusiasts, i.e. four-pin enthusiasts, concurrently manipulate the fan voltage. For example, if the CPU is busy with heavy pc paintings, the four-pin fan will increase the voltage to govern the temperature. Also, while the processor switches to mild duty, the fan pace and voltage are robotically slowed down.
You also can manipulate the rate of rotation withinside the case of three-pin fan connectors, however, the truth is that they’re to a few diplomae and now no longer as automated and specific as four-pin enthusiasts. Although they could manipulate their anxiety. That is, the much less anxiety we apply, the slower the rotation will be. This may not meet the wishes of contemporary-day PCs.
This is why PWM is the gift on contemporary-day motherboards and different video playing cards etc.
2. Noise
As you know, PWM regulates the rate of the fan. In this way, the fan adjusts pace in keeping with the want for temperature and similarly removes noise. While three-pin enthusiasts are completely spinning at excessive ability, you’ll enjoy a lot greater noise than four-pin enthusiasts.
3. Productivity
CPU enthusiasts are continually located on a copper or aluminum heatsink, use a three-pin fan or four-pin fan connector. Conventional three-pin connectors are designed for small enthusiasts with low energy consumption. While the four-pin fan connectors are designed for contemporary-day processors with better energy consumption.
4. Life expectancy
The lifespan of four-pin enthusiasts is longer than that of three-pin enthusiasts. This is due to the fact that four-pin enthusiasts alternate their pace and voltage relying on the specified temperature. In contrast, the three-pin fan spins the enthusiasts at excessive ability maximum of the time.
Can you position pin three on pin four?
Both are compatible. Even in case you insert a three-pin fan right into a four-pin motherboard slot, you could nevertheless manipulate the fan pace on any motherboard you have. Just slide out pin three and depart the more pin.
Do three-pin ARGB enthusiasts paintings with a four-pin RGB motherboard?
Yes, it’s going to paintings, however now no longer as expected. The primary trouble is that you could NOT energy and manipulate a three-pin ARGB lighting fixtures machine from an everyday four-pin RGB lighting fixtures header and there’s NO easy adapter.
What is the distinction between three-pin and four-pin RGB?
The three-pin RGB strains are for addressable RGB, permitting manipulation of man or woman LEDs. The four-pin RGB strains do now no longer have man or woman LED manipulation. Electrically speaking, in three-pin RGB strips, every LED acts as a shift sign in or similar, in which facts approximately its shade is handed to every LED.
