A 140mm fan covers more area than a 120mm at the same speed, so it can move similar air more quietly, but it needs a case with 140mm mounts. Every pick here is a 140mm fan, ordered by the number of fans in the box.
We ranked these 140mm case fans on fans in box, max speed and rated airflow using manufacturer specifications; we did not test these 140mm case fans ourselves, and where a maker leaves out max speed, we say so.

S-FDB Bearing1 of 5
Thermalright TL-C14C-S X3 140mm ARGB 3-Pack on Amazon (opens in a new tab)
What the TL-C14C-S X3 brings to the table is three 140mm ARGB fans, plus 75.8 CFM of rated airflow.
Best for
- Buyers who want a S-FDB bearing.
Skip if
- Skip it if rated airflow matters most to you; the RS140 2-pack offers 95.5 CFM.
Why we like it
It also comes as 3 fans and offers a 1500 RPM top speed. On pack size it ties with the Pure Wings 3 140mm 3-pack at 3 fans. On top speed it ties with the NF-P14s redux at 1500 RPM.
Its 75.8 CFM rated airflow is the lowest in this group; the RS140 2-pack leads at 95.5 CFM. On static pressure it trails the group at 1.93 mmH2O, while the RS140 ARGB 2-pack offers 3.46 mmH2O. It is the only pick here with a S-FDB bearing; the RS140 2-pack has a magnetic dome bearing instead.
It also comes with an S-FDB bearing. Check that your case has 140mm mounts in the positions you plan to use, and how many fan headers your motherboard offers. Its price falls between the NF-P14s redux and the RS140 2-pack, based on our last check.

- Bearing: S-FDB
- Lighting: ARGB
Pros
- 3 fans in the box
- 75.8 CFM rated airflow
- a S-FDB bearing
- ARGB lighting
Cons
- Rated airflow trails the RS140 2-pack (95.5 CFM)

Rifle Bearing2 of 5
be quiet! Pure Wings 3 140mm PWM High-Speed Fans (3-pack) on Amazon (opens in a new tab)
The Pure Wings 3 140mm 3-pack stands out for a closed-loop motor that holds speed against resistance, and it adds up to 2.44 mmH2O of air pressure.
Best for
- Buyers who want a rifle bearing.
Skip if
- Pass if a published top speed matters; this one has none.
Why we like it
It matches the TL-C14C-S X3 on pack size (3 fans). Its 2.44 mmH2O static pressure ranks second of 3 here, behind the RS140 ARGB 2-pack (3.46 mmH2O) and ahead of the TL-C14C-S X3 (1.93 mmH2O). You get a rifle bearing here, which sets it apart from the RS140 ARGB 2-pack and its a magnetic dome bearing.
It also offers nine airflow-optimised blades. Check that your case has 140mm mounts in the positions you plan to use, and how many fan headers your motherboard offers. With 3 fans, use a splitter or hub rather than several headers, and check the header's current rating; each fan's draw is on the label.
It was priced above the RS140 2-pack and below the RS140 ARGB 2-pack at the time of writing. There is no published top speed figure, whereas the RS140 2-pack offers 1700 RPM.

Highest Static Pressure4 of 5
CORSAIR RS140 ARGB 140mm PWM Fans (2-pack) on Amazon (opens in a new tab)
The RS140 ARGB 2-pack is built around eight LEDs per fan on a +5V ARGB connection, with 3.46 mmH2O of rated static pressure on top.
Best for
- Buyers who put static pressure first.
Skip if
- Skip it if price comes first: the NF-P14s redux cost less when we checked.
Why we like it
On the spec sheet, it comes as 2 fans and offers a 1700 RPM top speed. It matches the RS140 2-pack on rated airflow (95.5 CFM). Its 3.46 mmH2O static pressure is the highest here; the Pure Wings 3 140mm 3-pack comes next at 2.44 mmH2O.
Like the RS140 2-pack, it has a magnetic dome bearing, while the TL-C14C-S X3 uses a S-FDB bearing. It also comes with a daisy-chain connection from one PWM header. Check that your case has 140mm mounts in the positions you plan to use, and how many fan headers your motherboard offers.
ARGB lighting needs a 5V 3-pin ARGB header or the included controller; do not connect it to a 12V RGB header. It was the most expensive pick when we checked, so weigh what it adds over the Pure Wings 3 140mm 3-pack.
Key dimensions & specs
- Fans in box: 2 fans
- Max speed: 1700 RPM
- Rated airflow: 95.5 CFM

How We Chose These 140mm Case Fans
Each pick was assessed across 4 criteria weighted for real-world use.
- What we compared
- We lined up five 140mm case fans on pack size, top speed, rated airflow and static pressure, using each maker's published specs. We did not test them in-house, and top speed and rated airflow are missing for at least one pick.
- What every pick has in common
- All 5, from the TL-C14C-S X3 to the NF-P14s redux, state pack size and lighting.
- Where the specs have gaps
- The Pure Wings 3 140mm 3-pack gives no top speed; the Pure Wings 3 140mm 3-pack and the NF-P14s redux give no rated airflow.
- Price range
- From the NF-P14s redux to the RS140 ARGB 2-pack, all sat in the under $50 tier when we checked.
What to Look for in a 140mm Case Fan
Key buying criteria so you get the right fit the first time.
Pack size
Across these 5 picks pack size spans 1 fan (the NF-P14s redux) to 3 fans (the TL-C14C-S X3). Start with the TL-C14C-S X3 if pack size decides it.
Top speed across these picks
The RS140 2-pack tops top speed at 1700 RPM and the NF-P14s redux sits lowest at 1500 RPM; 2 picks share the top figure. If top speed is your first filter, the RS140 2-pack sets the ceiling at 1700 RPM. The Pure Wings 3 140mm 3-pack gives no top speed figure, so 4 of 5 picks are compared here.
How much rated airflow you need
The RS140 2-pack tops rated airflow at 95.5 CFM and the TL-C14C-S X3 sits lowest at 75.8 CFM; 2 picks share the top figure. The RS140 2-pack is the pick for rated airflow. The Pure Wings 3 140mm 3-pack and the NF-P14s redux give no rated airflow figure, so 3 of 5 picks are compared here.
Bearing
The TL-C14C-S X3 lists S-FDB; the Pure Wings 3 140mm 3-pack lists rifle; the RS140 2-pack and the RS140 ARGB 2-pack list Magnetic dome. Settling bearing first narrows 4 picks to 2 or 1 or 1.
Extras that separate them
The RS140 2-pack: 95.5 CFM of rated airflow. The RS140 ARGB 2-pack: 3.46 mmH2O of rated static pressure. The NF-P14s redux: a rated life above 150,000 hours.

Frequently Asked Questions
How does the Pure Wings 3 140mm 3-pack compare with the RS140 ARGB 2-pack on static pressure?
Between the top two, it is 3.46 mmH2O on the RS140 ARGB 2-pack against 2.44 mmH2O on the Pure Wings 3 140mm 3-pack, a 42% difference. The TL-C14C-S X3 is at the other end of this group with 1.93 mmH2O. The RS140 2-pack and the NF-P14s redux are left out of this ranking because their static pressure isn't stated; 3 of 5 picks are ranked.
What does the RS140 ARGB 2-pack add over the NF-P14s redux?
What it brings is pack size (2 fans against 1 fan) and top speed (1700 RPM against 1500 RPM). Both sat in the under $50 tier when we checked, so the gains in pack size and top speed cost little extra by tier.
Why is the RS140 ARGB 2-pack our Highest Static Pressure pick?
It carries the badge for the highest static pressure here (3.46 mmH2O). On static pressure it leads the Pure Wings 3 140mm 3-pack, 3.46 mmH2O against 2.44 mmH2O, a 42% margin. It makes sense for anyone who puts static pressure first.
Do the TL-C14C-S X3 and the NF-P14s redux differ on rated noise?
The TL-C14C-S X3 uses 26.4 dB(A); the NF-P14s redux uses 25.8 dB(A). The Pure Wings 3 140mm 3-pack, the RS140 2-pack and the RS140 ARGB 2-pack have no rated noise listed, so 2 of 5 picks are covered here.
What extras do the TL-C14C-S X3 and the Pure Wings 3 140mm 3-pack include?
The TL-C14C-S X3: three 140mm ARGB fans. The Pure Wings 3 140mm 3-pack: a closed-loop motor that holds speed against resistance. The RS140 2-pack: daisy-chain connection from one header.
Bottom Line
Our first pick is the TL-C14C-S X3, chosen for a S-FDB bearing. Look at the Pure Wings 3 140mm 3-pack for a rifle bearing, the RS140 2-pack for daisy-chain connection from one header and the RS140 ARGB 2-pack for the highest static pressure here (3.46 mmH2O) if those matter more to you.
Look for 140mm mount holes in the front and top of the case before ordering; many cases take 140mm fans only in some positions.
