Best 140mm Case Fan

Whether you spend hours on your PC doing video editing or are busy all day long in intensive gaming, the temperature of your system is likely to go up to high levels.

Although the PCs come with stock case fans, these alone are not enough to cool down the PC when it is being used for prolonged periods. 

With the burden solely being on the existing case fan, it tends to produce noise, which can be quite annoying, especially when you are deeply involved in your work or gaming. Eventually, the excessive load on the fan will lead to the wear and tear of the components of the PC. 

But hold on. You can bring the situation well under your control by getting your hands on a good quality 140 mm case fan. 

Where you spend a fair amount on other PC components, spending a few extra bucks on a case fan will be worth it.

In contrast to other PC cooling fans, the 140 mm case fans are more widely known and used as case fans having larger blades tend to be quieter and circulate more air around the system at low speeds.

With the wide variety of 140 mm case fans available in the market, it is not quite easy to make your pick. However, to make the task more straightforward for you, we have done an in-depth review of the top four 140 mm case fans available. A buying guide also follows the review so you can be sure about the choice you make for your PC.

Best 140mm case fans: Buying Guide

The best 140 mm case fans will cool down your PC system efficiently without costing you a hefty amount. Now that we have looked at the four best 140 mm case fans let’s move on to the details of factors you should put into consideration when buying a case fan.

Well-built motor

The first and foremost factor to investigate when buying a cooling case fan is that it should have a good quality motor. The motor has a strong link with the noise levels; hence a good quality motor will function quietly without breaking your tempo as you use your PC. The modern motor has smooth performance, and therefore a well-made motor will ensure that your PC is well supplied with optima airflow. 

Mounting and installation

For making the process of installation hassle-free, opt for a cooling fan that comes with either rubber fixed pins or has tool-less fixed pins. This will significantly save you on both time and effort, as you won’t have to invest hours struggling with the installation. Besides easy installation, the rubber fixed pins are also recommendable as they minimize vibration, so the fan functions quietly without producing any whirring noise.

Temperature sensors

The reliability and performance of the case fan can impair dramatically if it functions at high temperatures. Although every device comes with a temperature range, it is safe to keep the operating temperature below the upper limit of the range. 

A suitable temperature sensor protects your case fan from overheating, which adds to its lifespan and prevents the case fan from burning. The best 140 mm case fans can be paired with temperature sensors to clear away any malfunctions when the system heats up.


The case fan you choose should have a low wattage as higher wattage means the underrated performance of the system. It is good to check the wattage of the case fan you are willing to buy. The average watts of electricity is 70 watts, so a highly efficient case fan will have a wattage below this.

Remote control

If your case fan comes with a remote control, then you are in great luck as it is the most beneficial control for a cooling fan. You can use the portable remote within a particular range so you can easily place the case fan in hard to reach places of the PC and control it.
