What is the difference between a 3 pin fan and a 4 pin showcase fan? The 4 pin winnow comes with upgraded benefits with the fan speed ascertain, whereas a 3 pin fan does not. Only that does not make a 3 bowling pin fan paltry at every last.
Computer incase fans are material tocool blue the CPU temperature and assistanc it run smoothly without interruption or early serious damage to the chips.
However, every modern motherboard features header pins for 4 pin fan connections where you can connect both 3 pin and 4 pin fans. But which would be ideal from 3 pin vs 4 pin fan selection?
Whether you are entirely a novice in computer hardware or just want to be sure nigh these 2 case fans, in today's friendly clash, we will sort this mental confusion out from your head.
Stay tuned to the end to see the winner of this engagement.
3 Peg Vs 4 Pin Lover- Quick Comparison
| Key Points | 3 Immobilise Case Fan | 4 Pin Case Fan |
| Pin Count | 3 pin goes any 3 pin Oregon 4 pin motherboard header | 4 pin goes 4 pin mobo head |
| Noise | Higher to mid-stratum fan dissonance | Maximum quieter fan |
| Fan Focal ratio Hold | Controls the buff using DC Voltage | Controls the fan upper using PWM mood |
| Fan Control Ability | General verify accession | Superior level of control option |
| Price | Cheaper | Lean costlier than the 3 pin winnow |
Now, deep dive into a elaborate comparing where we have a clear explanation regarding these 2 types of lover functions.
3 Pin Vs 4 Pin Rooter Connector
When you are a newbie and silly with the 3 pin and 4 pin fans, the first that catches your eyes is the connector tholepin.
Yes, the basic and not-major difference between a 3 pin and 4 pin fan is a 3 pin fan comes with 3 wirings to connect to the 3 pin header of your information processing system motherboard, whereas a 4 pinfan comes with 4 wires.
In both fans, 3 wires feature quite the same- ground, live, and speed sensing element connection signal pin.
Here, the common 3 wires/ pins are-
- Conducting wire for ground association- 0 V
- Hold ou wire- 12V/ 5V
- Connection for fan speed sensor
And the extra fourth pin/wire that you find on the 4 pin fans is the PWM mode connection that controls the rpm speed.
Notes: In a 4 pin fan connectors, the 2Nd and 3rd wire comes as red/yellow/green people of colour also
Nevertheless, you don't have to bother many if you are a bit brand conscious. Nowadays, most of the quality brands hail with case fans of both types that too ata decent price. Similarly, the just about demanding-be quiet case fans come with both the 3pin and 4 pin connection wire.
Do you know, what the best part is? You can connect both 4 and 3 pin lover to 4 pin headermotherboard.
Sounds confusing? Go on recitation we will discuss this in detail on the subprogram and compatibility point.
4 Flag Rooter Vs 3 Pin Fan Speed Controller
Here comes other dispute that is in the speed controlling option. You see, the speed of the computer casefan is calculated by the rpm (Rotations per Minute) of the fan blades.
And so, how is information technology related to the 3 pivot and 4 pin fan? Well, a 3 stick fan speed is controlled by the DC Voltage power of that lover. If the fan speed decreases, the Potential difference index decreases as healed.
On the other hand over, the rpm speed of a 4 pin fan does non have any joining with the DC power Voltage. That means, when you try to increase or diminution the fan speed, IT does not signal the Voltage power, and your fan does not lack in power Voltage.
And that is the bigger benefit with a 4 pin winnow. The fan speed is not contingent the Electric potential power rather it is controlled by other selection legendary as PWM mode.
And then, people also know a 4 pin case fan as the PWM(Pulse Width Intonation) or PDM (Pulse Duration Intonation) rooter,whereas the 3 pin rooter as a voltage-controlled fan.
If you are curious to know what PWM is, in chunky, we can say that it is just a method of decreasing any Voltage signal(present the fan RPM speed) without even descending the Voltage big businessman.
Voltage Pressurised fan Vs PWM Fan Revolutions per minute Functions
Here, we come with another interesting part which is the function of these fans. Though you already get laid a major difference that it differs is the fan controlling feature article, we volition just show you a clear explanation of how these 2 fans differ in their working, especially when it comes tofan speed.
Equally we give mentioned earlier, a 3 pin fan speed is controlled by the Voltage power contrarily, a 4 pin fan bucket along is controlled by the PWM mode which is correlated its 4th bowling pin.
It means in the case of a 3 pin lover, when you try to lower the devotee speed from BIOS settings, information technology decreases the Voltage powerat the same, from 12V to 8/9V, depending connected the speed reduction percentage.
Well, therein fan hurry reduction, the fan speed is reduced along with the noise of the 3 pin fan, but IT too reduces the Voltage power which is the biggest drawback here.
This speed reducing sometimes creates a coherence that can affect the chilling capacity inside the case.
So, it would not be ideal to tighten a 3 peg fan speed when you are working or playing something that makes the C.P.U. temperature rise high-pitched.
Happening the unusual side, if you decrease the 4 pin fan revolutions per minute speed, you are one step away, and you are benefitted from the advantage of its PWM mode.
You throw known that a 4 pin fan comes with 4 wiring pin and the 4th pin whole works here when it is timeto reduce the rpm speed.
What happens here is even if you frown fan hotfoot to 50%, it all the same runs with the same maximumvoltage rating of 12V power.
Here, all credit goes to the PWM mode.That 4th pin takes the signal of reducing and chops it up into the tiniest wave signal which is on the far side our deliberation. And this oftenness waving signal completes a full wave cycle so presto with its tiniest parts without rental the Voltage pearl for a minute.
As a result, information technology does not demand the Voltage king, and it can continue with spinning without lowering the Voltage for a moment.
3 Pin Fan vs 4 Fall Lover Haphazardness Difference
After this beautiful detailed discussion, information technology is crystal clear now a 3 stick devotee is noisier than the 4 thole case winnow.
Well, we tail end't neglect the traditional one for making people bring the updated one that is the 4 pin PWM fan with much quieter secure operation.
But you see, when you want to enjoy the best, you require to be upgraded along with your operational devices.
So, get a 4 pin PWM casing fan if you need to select between a 3 pin devotee and a 4 pin case fan to enjoy a noise-free smooth fan spinning and enjoy your heavy tasking without fear of losing power efficiency.
Contrarily, assume't underestimate the 3 pin case fan too. Nowadays, many brands make approximately of the quitter 3 pin fan. For exemplify, Arctic F12 120 mm 3 pin fan comes with a quitter noise that can cost the best cull for money ever.
4 Trap Fan Vs 3 Pin Fan Motherboard Compatibility
Remember at the showtime point, we have said that you canful connect both a 3 pin and 4 tholepin casefan to a motherboard with 4 personal identification number cope pin. Yes, now, we will show you another exciting part.
When it comes to intelligent about the compatibility of the case fan with your motherboard, you father't have to represent worry for Eastern Samoa long as your motherboard comes with the 4 pin header chip.
Yes, we can say information technology confidently because you can connect some types of pin connectors to a 4 pin header on the motherboard.
Wait! You must follow a tactic when you insert the copulative telegraph to the header pin.
If you closely note, you can see a describe marked or 3 of the pin lintel is separated from the relief nonpareil. This indicated that if your grammatical case fan comes with the 3 pin connective, you take to insert that therein separated 3 pins header matched the connections.
However, what if you own a motherboard from your grandp's grandfather's sentence? And you want to buy a 4 pin case fan. Now, righteous get a 3 pin to 4 pin adapter to connect it.
What about Mary Leontyne Pric Difference?
Obviously, a 4 pin rooter costs higher than a 3pin case devotee. Just if you look at the longevity and quieter fan operation, acquiring a 4 pin buff would constitute the wiser decisiveness.
But no outcome, if you experience whatever budget issues, you can go with the Central processing unit fan that comes with a 3 pivot connector. You see, the Noctua fan has great popularity for it high quality and cooling capacity. And the Genus Noctua 120mm fan with 3 pin connector is famous as a gaming console too.
Too, remember, you lack the rpm speed control feature you fanny set out with the PWM fans.
Which Buff Should You Buzz off for Your PC?
To end this battle, we can be at sea about which one is nonesuch to birth between 3 pin vs 4 pin fan.
It's quite challenging to make indefinite winner over the other equally some fans come with quality build and the requirements that any general to heavy performance user PC need. Simply undoubtedly, it is true that the fan that comes with a 4 pin connector can provide you with some additional benefits that a 3pin buff can never do.
However, for a budget lay out quality pick, 3 immobilize connection fans are worthy enough.
But who would not want to enjoy the best with extra benefits?
Frequently Asked Questions (FAQs)
Of course, you tin inset a 3 pin fan into a 4 bowling pin fan header. But you need to Be scrupulous with the connexion pin which pins should get in contact. Here the orthodox 3 pins will be connected, and the 4th one bequeath be left outside disconnected.
Bash 3 pin fans run at full speed?
Definitely, yes. A 3 pin fan will run with its maximal speed no matter you connect it to a 4 pin or 3 pin cope.
Are 3 trap fans PWM?
Atomic number 102, 3 oarlock fans are not PWM, preferably, they are long-familiar as voltage fans or D.C. Voltage fans. 4pin fans are PWM fan.
