With a large diameter equivalent to the fans found on 280mm AIO coolers, these fans are a tremendous cooling solution for an over-heating PC. But though the initial design would suggest that PC fans are simple, the opposite is true – the difference between the best and worst case fans in the market is significant.

In order to make sure you pick up the best, we’ve put together a buyer’s guide of top 140mm PC case fans – factoring in different style preferences and budget requirements. Whether this is your latest PC build or a quick low-budget upgrade, you should find the perfect 140mm fan for your needs!

Pros
  • Affordable

For a balance of affordability and quality that’s hard to match, the Arctic P14 140mm case fans are our best bets for PC cooling. Boasting a great design that is flexible in all the right places and rigid everywhere else, these fans are easily installed into any PC build. With optional RGB versions available for a minor price bump, there’s a lot to love about these case fans.

They may be too good, however: some users report issues with fans rattling slightly at lower RPM rates, which can prove frustrating for those who don’t maximize their PC performance. But for truly arctic-climate PC cooling under heavy-duty loads, the P14 are unrivaled as 140mm PC case fans!

Best Performance 140mm Case Fan: Noctua NF-A14

Noctua NF-A14 Chromax

Fan Diameter

140mm

Rotational Speed

800-3000RPM

Voltage

12V

Pros
  • Sterling build quality
  • Moisture and dust-resistant
Cons
  • Premium price

Noctua are a highly reputable manufacturer of premium PC parts, and the NF-A14 fans are a drop in the ocean of their top components. Boasting an impressive top speed of 3000RPM, these are sure to keep your CPU from overheating. Additionally, they come IP52 certified for water and dust, to ensure the best airflow without interference.

That said, you’ll be paying top dollar for these case fans: at double the average price of the standard case fan, these are an investment in quality. They justify the price, however, and we still recommend the NF-A14s as the best performance 140mm PC case fans on the market!

Best Vibration-Proof Case Fan: be quiet! Silent Wings Pro 4

be quiet! Silent Wings Pro 4

be quiet! Silent Wings Pro 4

Fan Diameter

140mm

Maximum Rotational Speed

2400RPM

Voltage

12V

Pros
  • High rotational speed
  • Smooth and silent airflow
Cons
  • Inconvenient manual switch

For a premium vibration-proof 140mm case fan, the Silent Wings Pro 4 from “be quiet!” is your best bet. With an adjustable maximum speed of 2400RPM, this vibration-compensated fan is nearly inaudible when running general-purpose to high-end PC programs. Air flows easily through your PC and temperatures are kept low with ease.

There is one design flaw in the Silent Wings Pro 4, unfortunately: the manual switch for alternating between different fan settings is inconveniently located on the case fan body itself, which is difficult to reach from most standard fan placements. If this isn’t a concern, however, then purchase the Silent Wings Pro 4 as a top 140mm case fan!

Best Dust-Proof 140mm Case Fan: Cooler Master Mobius 140P

Cooler Master Mobius 140P

Fan Diameter

140mm

Maximum Rotational Speed

1900RPM

Voltage

12V

Pros
  • Intuitive custom RGB
  • Anti-sway system
Cons
  • Noise under heavy loads

If you are looking to protect your PC’s interior whilst also letting air flow through, invest in one of the Cooler Master Mobius 140P case fans. Boasting a layered ring-blade design, this RGB fan allows for stylish and near-silent PC cooling without trapping dust or moisture in the PC itself. The Mobius 140P also comes with an anti-sway system that prevents the fan casing dislodging during high running speeds – and with a max rotation of 1900RPM, that’s definitely welcome.

However, at those maximum rotation speeds, you’ll experience some louder-than-average fan noise. It’s a shame to see an otherwise great fan case struggle – though it does ultimately keep your PC cool. With that in mind, we still think the Mobius 140P is worth the expense!

Are 140mm Case Fans Worth It?

140mm case fans are ideal cooling solutions for most PC builds. Large enough to provide ample airflow, but small enough to fit in most PC cases, they strike the ideal middle ground for most. They can range in price, with some of the best models on the market being affordable and some poorer models being more expensive.

Overall, however, we think that 140mm case fans are a worthwhile investment for PC builders of any skill level. Though the market can vary, the best 140mm case fans always consistently cool your PC – and look great doing it.

FAQs

How often should I replace my case fans?

This depends on the case fans and how heavily they are used: the best case fans can last a while under high yields before needing replacements, but it can vary from model to model. If your fans are beginning to fray or make noise, that’s a clear warning sign – or a sign that you may need to invest in a CPU cooler.

How many PC case fans do I need?

On average, a hot-running PC needs 2-3 fans in order to stay cool. A higher-spec model may require more, or a dedicated cooling solution. Gauge how many case fans you need by checking your PC’s temperature benchmarks, and work backward from there!

In Summary

That concludes our ranking of the best 140mm PC fans! Across a range of protective and stylistic preferences, we hope you found the right PC case fan to suit your build and keep your build running smoothly and quietly!
