Best PC fans in 2024

The best PC fans will keep even the most intense gaming rig cool. PC builders often overlook fans when buying components, but cool hardware is essential for optimal gaming performance. We recommend making sure your fans are up to a high standard, for both cooler and quieter PC operation.

Right now, our testing points to the Noctua NF-A12x25 PWM as the best PC fan today. With Noctua's reputation for making a mean PC fan, that should come as no surprise to many. Though for anyone looking to spend less, the cheaper Noctua NF-S12B redux-1700 also does a great job. Neither fan is loud, either.

But I'm sure we can all agree that poor airflow is bad. It'll lead to your PC operating at suboptimal temperatures, which is sure to affect the performance and durability of your machine's important parts. If you plan on overclocking, a couple of extra fans (or the best CPU coolers) will help keep everything running smoothly. I've picked out some of the best PC fans from those tested below, noting the key points that make them stand out. Stay cool.

Jacob has been testing fans for over half a decade. As someone that often likes to get into the weeds for each and every PC build he works on, he pays close attention to pressure ratings and airflow measurements of each one. He brings that level of attention to this guide, along with his very own at-home wind tunnel and anemometer setup to test manufacturer's claims and decide on his top picks.

The Noctua NF-A12x25 PWM is a clear and easy pick for the best PC fan. If you're looking for a top-tier 120mm model that can move a lot of air, the awkwardly named NF-A12x25 blows away the competition. Of all the fans we tested, this model pumped the most air through our test rig.

You can decide between khaki-and-mud or black versions—pick your poison. We've the Chromax.black version of the fan for testing, as seen in the pictures above, though it's only really different for the smart black colourway and additional Chromax corner pieces. The specs all remain the same.

The NF-A12x25 is a great all-rounder and can be used as both a case fan or stuck on a radiator with great effect. For a bit more info on that, and to understand Noctua's naming, check out Noctua's guide.

The NF-A12x25 was the quietest fan we tested when running at lower RPM. Our numbers have it putting out less noise at 1200 RPM than some fans running 300 RPM slower. Since those mid-range speeds are generally more likely to come up in day-to-day use, the NF-A12x25 is an excellent choice for your average gaming PC while still giving it the headroom to spin up to 2000 RPM in the middle of a heatwave.

The NF-A12x25 lives up to the legacy we've come to expect from Noctua. It's also a nice touch how many accessories come with the NF-A12x25, from a 12-inch extension cable and a Y-splitter to many rubber vibration dampers. The price is high, but it's hard to argue the value.

While work is still being done to nail down its next-gen fan with an absurdly small clearance between fan tips and enclosure, until that's ready and we've had a chance to test it out, the Noctua NF-A12x25 is a great choice.

Not the quietest Noctua fan

Noctua builds fans that last a long time, move a lot of air, and do it quietly. A few issues, however: until recently, buying Noctua fans meant committing yourself to a hit-or-miss khaki-and-mud color scheme straight out of the '70s and spending a pretty penny. 

Thankfully, this NF-P12 redux-1700 helps out in both departments, as the more affordable and stylish option to the NF-A12x25 PWM.

Noctua's redux line comes in a modern gray-and-another-gray look that won't detract from the rest of your PC build. It's not as quiet nor as efficient as the blacked-out NF-A12x25 PWM, but it is much cheaper. It's more or less half the price. The NF-P12 redux-1700 balances great performance with a budget-friendly price tag and looks great in the process. It's a fan more tailored to use on a radiator than as a case fan, but it does well in both uses. It's a bit more of an all-rounder than the NF-S12B redux-1200, which we used to recommend in this spot, and runs faster too.

You can save some money and pick the NF-S12B redux-1200 if you are solely using these fans for your case cooling. Though I do like the flexibility in the redux-1700 for about a dollar more. We've a properly budget PC fan option below, should you need it.

You'll find no RGB lighting here—no frills of any kind, really. But the NF-P12 redux-1700's Self-Stabilising Oil Pressure Bearings will last for years while moving lots of air around and keeping extremely quiet. It's a clear pick for any modern PC build.

3. Scythe Kaze Flex 120 PWM

The best budget PC fan

Specifications

Bearing type: Fluid Dynamic Bearing
RPM range: 300–1200
Listed CFM: 51.2
Listed dBA: 24.9
RGB: No

Feels cheaper than the rest

Relatively loud at any speed

As the best budget PC fan, the Kaze Flex 120 PWM arrives in a cheap plastic package, looking more like it came from an auto shop than a modern PC retailer. Side-by-side with Noctua's Redux packaging, or Corsair's weighty boxes, Scythe feels like a budget fan solution.

To be fair to Scythe, it is selling the Kaze Flex for pretty cheap. And once it's inside your PC case you aren't going to notice the cheaper plastic so much.

The Kaze Flex 120 PWM we tested is one of the company's better models, though. At 1200 RPM, the Kaze Flex 120 moved more air in our test rig than some of the competition (Corsair, for instance) did at 1400 or even 1600 RPM, presumably due to having eleven blades where most fans have only nine. Lots of air goes hand-in-hand with noise, though, and indeed the Kaze Flex 120 PWM is also noisier than the competition at any given speed setting—though since it tops out at 1200 RPM, the noise is never as bad as models that spin up to higher speeds.

If you want a decent budget-friendly fan and the SF-12B isn't doing it for you? Scythe's blade-heavy blower might be the right choice. And hey, one more company hasn't dipped into the RGB LED well yet. That's worth something.

The best RGB PC fan

4. Corsair LL120 RGB

The best RGB PC fan

Specifications

Bearing type: Hydraulic Bearing
RPM range: 600–1500
Listed CFM: 43.3
Listed dBA: 24.8
RGB: Yes, with Corsair Lighting Node Pro
140mm model no.: LL140 RGB

Top-tier RGB lighting
+
Surprisingly quiet at full-speed

Reasons to avoid

-
Slightly louder at mid-range speeds
-
Really not for budget builds

Do you need RGB fans? No, but do you want RGB fans? Of course. They can look great in an all-glass case or even through a traditional side window, and if you're chasing that full-cyberpunk aesthetic, then Corsair's LL120 Pro RGB fans are the best you can buy.

The LL120s are packed full of RGB LEDs. Each has a complement of LEDs shining out from the rotor, diffusing light down the blades' length as they spin. Then, a separate ring of light is embedded around the housing's outer edge. As a result, the LL120s are the brightest and showiest fans we tested and a perfect fit for any RGB addict.

They're not just for show, though. The LL120s are also solid fans, lighting or no. At mid-range speeds, we found during testing that they tend to be slightly louder than the competition, but they do ramp up to a solid 1500 RPM and that will make them louder than some 1200 RPM fans.

The biggest problem? They're expensive. Like, incredibly expensive. To use LL120s, you need to commit to purchasing a three-pack of fans with an included Corsair Lighting Node Pro, a package that lists for $120. Additional fans will run you $35 each. That's a lot of money, even if the results are stellar.

5. Cooler Master MF120R A-RGB

The best budget RGB PC fans

Specifications

Bearing type: Rifle Bearing
RPM range: 650–2000
Listed CFM: 59.0
Listed dBA: 31.0
RGB: Yes, either through motherboard or Cooler Master's controller
140mm model no.: N/A

Reasons to buy

Really, really loud at top speed

Not exactly quiet below that either

Cooler Master's RGB design is a bit less high-tech than the Corsair LL120, featuring only fan-blade lighting instead of the second ring around the outside. It's still an attractive fan, though, bright and with smooth transitions. And while the package lists for $99, you can usually find it on sale much cheaper. Add in the fact that additional fans only cost $20 each, and you're set to save a whole lot of money on your cooling setup.

So what's the catch? They're loud. Like, really loud. Even Cooler Master admits it, listing the MF120R at 31 dBA. In our own tests, the MF120R kit was reasonably quiet at 1200 RPM but completely unusable at its maximum 2000 RPM speed, posting the loudest measurements of any fan we tested—louder than the other 2000 RPM fans we tested, the NZXT Aer RGB 2 and the Noctua NF-A12x25.

Granted, the MF120Rs move a lot of air at top speed, tying the Noctua NF-A12x25 for the highest airflow. There's no way you'd want to run them at that speed, though, at least not for typical gaming use. Still, you get a full RGB lighting setup and some pretty strong fans for a fraction of the cost of Corsair's kit. As long as you limit the MF120Rs to running at 1200 or 1500 RPM max, they might be a good alternative.

Not the quietest at full speed 

In a world where the number of RGB LEDs on a fan is often the main selling point, the frill-free styling of the Thermaltake Toughfan 12 Turbo makes for a refreshing change. These aren't your average run-of-the-mill case fans. These aren't standard case fans; they're high static pressure fans—ideal for use with radiators and pushing air through grills and confined spaces. If you're looking to upgrade your CPU cooler or piecing together a bespoke system, these are the kind of fans you need. 

You can use them as straight case fans, but you're going to pay a premium to do so. At $30 a pop, these are at the higher end of the price spectrum, but the specs are at least impressive. These are PWM controlled with a maximum speed of 2,500RPM, where you're looking at 3.78mm-H2O air pressure and airflow of 72CFM. Impressive given the maximum noise level of 28.1dBA, which is noticeable without annoying; you can also run them much slower and quiet.

You can also pick these fans up in a non-Turbo guise, which means you save $5 on each one, and they top out at 2,000RPM, that's 500RPM less than we have here. They don't shift as much air as the Turbos can, but they're quieter for it, too, so the choice is yours. 

PC fan FAQ

Do I need 120mm or 140mm PC fans?

This really depends on whether you have the space for 140mm fans inside your PC case. If you do, they're likely the best option. 140mm PC fans can move more air while running at slower RPM, which means they're as effective, if not more effective, while being much quieter. 

Though 120mm fans can have the benefit of being compact enough that you can fit in three 120mm fans in place of two 140mm fans, which will be louder but can be effective in moving air to the upper and lower reaches of your PC case.

Do I need PWM or DC fans?

The best option for almost every use case today is PWM. This stands for Pulse Width Modulation, and it means the fan is able to be controlled via an additional signal that can enable lower operating speeds and finer grain control compared to pure DC-only fans. To score that additional PWM signal on a DC fan, a fourth pin is required on both the fan connector and motherboard header. If you only have three pin headers or connectors, you're stuck with plain DC.

DC is pretty great for fan control. It's not quite as fine-tuned as PWM can be, and DC fans often have higher RPM floors meaning they will run faster even set to their slowest speed, but they're more or less going to get the same job done almost just as well.

These days, PWM fans are almost everywhere and I haven't seen a motherboard without four-pin fan headers in a long time. So, while you should definitely check your headers on your motherboard, it's probably PWM you're after.

How do I improve my PC's airflow?

Poor airflow will have a major impact on your PC's performance. There are varying opinions on fan placement and which provides the best airflow. A good place to start is to avoid a neutral pressure environment as stagnant, hot air collecting around your components won't help any PC.

Essentially, you'll want to make sure that you have fans for intake and exhaust so that the air is moving inside your PC case. Both positive and negative air pressure setups will do the job well and ensure that cool air is being pulled into your case while hot air is expelled.

How we test

There are a lot of case fans out there, so we had to set a few guidelines. First, we limited our tests to 120mm fans. It's not because we hate 140mm. On the contrary, 140mm fans are generally quieter and move more air, making them a great choice for any case that can handle the larger size. But 120mm is still the "default" case fan, and it's hard to compare different fan lines when you're also comparing different sizes, so we stuck to 120mm versions as a control. (We've tried to provide the model number for the 140mm version where possible.)

With that in mind, we contacted a number of the most popular case fan manufacturers and had them send over both their best-selling and their personal favorite 120mm models. Then we hacked together a miniature wind tunnel with an anemometer inside, a device that measures airflow. This helped us match airflow between different fans at different RPM.

We then maxed out the RPM on each fan to test a theoretical airflow limit and keep an ear on the accompanying noise—all fans tend to ramp up in volume at max RPM, but some absolutely screech. Chances are you'd never run most of these fans at 100 percent—that's why they're PWM fans! But if you have an older motherboard without PWM (or have a system that runs hot), you might hit this limit, and it's good to know how loud your PC could potentially get and how much air these fans hypothetically move. 

As for RGB lighting? Well, we have eyes for those tests.
