A single unlit fan is the simplest way to quiet a noisy PC or fill a radiator. These five are sold one at a time, so you buy only as many as you need.
Figures come from each listing; we did not test these fans.

Our Picks
Best PC Cooling Fan1 of 5
Noctua NF-A12x25 PWM
The Noctua NF-A12x25 is an unlit 120mm fan with Sterrox LCP blades and a 0.5mm tip clearance.
Best for
- Quiet upgrades.
Skip if
- Worth skipping when sold as a single fan, so a full case costs more is a problem.
Why we like it
It tops out at 2,000 RPM, and the included Low-Noise Adaptor caps it at 1,700 RPM. It has a record-tight 0.5mm tip clearance and an LCP blade, and comes with anti-vibration mounts, a Y-cable and an extension. Its 2000 RPM top speed is the lowest in this group; the Silent Wings Pro 4 leads at 3000 RPM.
Check that your case has 120mm mounts in the positions you plan to use, and how many fan headers your motherboard offers. At our last price check it topped the group, with the NF-F12 iPPC-3000 the nearest cheaper option.
Key specs
- Fans in box
- 1 fan
- Max speed
- 2000 RPM
- Rated noise
- 22.6 dB(A)
- Lighting
- None
Pros
- 0.5mm tip clearance and Sterrox LCP blades
- Low-Noise Adaptor that caps speed at 1700 RPM
- Anti-vibration mounts and a Y-cable in the box
Cons
- Sold as a single fan, so a full case costs more
- Top speed trails the Silent Wings Pro 4 (3000 RPM)
- Costs more than the Pure Wings 3 at the time of writing
Best Speed-Switch Fan2 of 5
be quiet! Silent Wings Pro 4 120mm PWM
The Silent Wings Pro 4 adds a speed switch that raises the ceiling to 3000 RPM, which suits dense radiators.
Best for
- Radiators and heatsinks.
Skip if
- Pass on it if sold as a single fan, so a full case costs more rules it out for your setup.
Why we like it
It shares the Silent Wings 4's fluid-dynamic bearing and 6-pole motor. A funnel-shaped outlet and tight tip clearance build high pressure for radiators, yet it is near silent at normal speed. On top speed it ties with the NF-F12 iPPC-3000 at 3000 RPM.
You also get blades tuned for radiators and heatsinks. Check that your case has 120mm mounts in the positions you plan to use, and how many fan headers your motherboard offers. Its price falls between the Pure Wings 3 and the NF-F12 iPPC-3000, based on our last check.
Key specs
- Fans in box
- 1 fan
- Max speed
- 3000 RPM
- Bearing
- Fluid-dynamic
- Lighting
- None
Pros
- a 3000 RPM top speed for radiators
- a Fluid-dynamic bearing
- Speed switch with medium, high and ultra-high modes
- 6-pole motor
Cons
- Sold as a single fan, so a full case costs more
- Costs more than the Pure Wings 3 at the time of writing
Best Rigid-Frame Fan3 of 5
Phanteks T30-120
Phanteks's T30-120 uses a rigid LCP frame and blades with a switch for three fan profiles.
Best for
- Tuning sound to taste.
Skip if
- Choose another pick if you can't accept this: sold as a single fan, so a full case costs more.
Why we like it
The maker gives no airflow or speed figures. Its liquid crystal polymer blades are rigid, and a switch picks silent, balanced or extreme fan profiles. It also comes with acoustic tuning toward a lower frequency range.
Check that your case has 120mm mounts in the positions you plan to use, and how many fan headers your motherboard offers. The maker doesn't give its top speed; if that figure matters, the Silent Wings Pro 4 offers 3000 RPM.
Key specs
- Fans in box
- 1 fan
- Lighting
- None
Pros
- Rigid LCP frame and blades
- Switch with three fan profiles
- Acoustic tuning toward a lower frequency range
- An LCP frame and a three-profile switch
Cons
- Sold as a single fan, so a full case costs more
- No published top speed
Best Industrial Fan4 of 5
Noctua NF-F12 iPPC-3000 PWM
Noctua's NF-F12 iPPC-3000 spins from 750 to 3,000 RPM and carries IP52 dust and water protection.
Best for
- Dusty rooms and workstations.
Skip if
- Worth skipping when sold as a single fan, so a full case costs more is a problem.
Why we like it
At a rated 43.5 dB(A) at full speed, it suits radiators and workstations more than quiet desks. It is an industrial-grade 3,000 RPM fan with IP52 dust and water protection and a fibreglass-reinforced frame. It suits radiators and hot enclosures.
It matches the Silent Wings Pro 4 on top speed (3000 RPM). You also get a Focused Flow frame for static pressure. Check that your case has 120mm mounts in the positions you plan to use, and how many fan headers your motherboard offers. When we checked, only the Silent Wings Pro 4 and cheaper picks cost less, and the NF-A12x25 cost more.
Key specs
- Fans in box
- 1 fan
- Max speed
- 3000 RPM
- Rated noise
- 43.5 dB(A)
- Lighting
- None
Pros
- a 3000 RPM top speed for radiators
- 750 to 3000 RPM range
- IP52 dust and water protection
- Focused Flow frame for static pressure
Cons
- Sold as a single fan, so a full case costs more
- Costs more than the Pure Wings 3 at the time of writing
Best Budget Single5 of 5
be quiet! Pure Wings 3 120mm PWM
be quiet!'s Pure Wings 3 is a plain, low-cost single fan with a rifle bearing rated for 80,000 hours.
Best for
- Replacing stock fans cheaply.
Skip if
- Skip it if this is a deal-breaker for you: sold as a single fan, so a full case costs more.
Why we like it
Its frame outlet is shaped for radiators, and it runs at a very low minimum speed. Seven airflow-optimised blades reduce noise, and the frame outlet is tuned for radiators. Check that your case has 120mm mounts in the positions you plan to use, and how many fan headers your motherboard offers.
Before buying, weigh one limit: no published top speed. It was the cheapest of the group when we checked; the Silent Wings Pro 4 was the next step up. If pack size is your priority, the NF-A12x25 (1 fan) is the stronger choice.
Key specs
- Fans in box
- 1 fan
- Bearing
- Rifle
- Lighting
- None
Pros
- a Rifle bearing
- Frame outlet shaped for radiators
- Very low minimum speed for quiet running
- Rated 80,000-hour bearing life
Cons
- Sold as a single fan, so a full case costs more
- No published top speed
How We Chose These PC Cooling Fans
Alex Morgan compared the manufacturer specifications, connectivity, warranty terms and compatibility of every pick. Figures come from the makers unless a third-party source is named; we did not test these products ourselves.
- How these picks were ranked
- We compared five case fans on pack size, top speed, rated noise and bearing from manufacturer specifications. Nothing was tested in-house; 2 of the 5 fields compared are stated for every pick, while top speed and rated noise have gaps.
- What every pick has in common
- All 5, from the NF-A12x25 to the Pure Wings 3, state pack size and lighting.
- Where the specs have gaps
- The T30-120 and the Pure Wings 3 give no top speed; the Silent Wings Pro 4, the T30-120 and the Pure Wings 3 give no rated noise.
- Price range
- From the Pure Wings 3 to the NF-A12x25, all sat in the under $50 tier when we checked.
What to Look for in a PC Cooling Fan
Key buying criteria so you get the right fit the first time.
How much top speed you need
Across these 3 picks top speed spans 2000 RPM (the NF-A12x25) to 3000 RPM (the Silent Wings Pro 4). Start with the Silent Wings Pro 4 if top speed decides it. The T30-120 and the Pure Wings 3 give no top speed figure, so 3 of 5 picks are compared here.
Bearing
The Silent Wings Pro 4 lists Fluid-dynamic; the Pure Wings 3 lists rifle. Settling bearing first narrows 2 picks to 1 or 1.

The T30-120: a switch with three fan profiles. The NF-F12 iPPC-3000: IP52 dust and water protection. The Pure Wings 3: a very low minimum speed for quiet running.
Budget
All 4 sat in the under $50 tier when we checked, from the Pure Wings 3 at the low end to the NF-A12x25 at the top, so decide on features first.
