Do 140mm fans cool better than 120mm?

The argument between what fan size is more effective at getting the job done has always been a big conversation topic in the pc building community for years. The 140mm is overall a better pick than the 120mm options.

Since the 140mm is larger by 20mm, it spins slower than what a 120mm fan would spin to reach the same cooling temperatures. However, because of its slower spinning, this means it will make less noise. This is often the main reason people buy the bigger 140mm fan over the 120mm as it is more useful. Because the 140mm is larger and spins slower to match the cooling temperatures that a 120mm fan can output, this means it can also go faster increasing cooling temperatures, and this does come with its negatives as this may be lower than a 120mm fan at its maximum cooling potential.

The final answer to the question is yes, and the 140mm cools better than 120mm if the right settings are applied.

What to look for in a Case fan?

Choosing a fan for someone can be difficult as you might not have a single idea of what to look for in a fan or what is good about the fan you are looking at when buying. We are here to help you solve this problem and talk you through what you have to look for.

When choosing a case fan, you might want many different things for your fan. This could be looks, efficiency, size or something else. We will talk through some of the key things you should look for when deciding what fan to buy and what fan is perfect for you. Below are some of the things you should be thinking of when searching for a fan to buy.

How the fan looks

Choosing the fan solely on looks is not the best idea. Some fans can look amazing with bright, flashy lights but be really loud or have other problems that you have not read into. If you want a fan that has all the looks, make sure it matches the case and looks good in the case. This can be done by looking at your already existing colour scheme that your case has.

Remember efficiency of the fan should come first. Most fans do have RGB lighting, making them stand out in computer cases and making your pc setup shine how you want it to. Some fans might be excellent but come with horrible colors, so make sure you are also taking this into account when purchasing your new fan.

The size of the fan

The size of the fan is critical, and you will need to figure out what size of the fan fits your case. Most 140mm fans will fit all cases in this scenario; however, if you have a micro case, then this could cause chaos problems as the fan might be too big for the case. Checking the dimensions of the fan slots available in the case is necessary before purchasing a cooling fan.

How efficient is the fan for cooling

What you should look into the most out of everything is how efficient is the fan. It would be best if you asked questions like how loud the fan is, how good the fan is at cooling your pc. I need more than the regular 2 fans as the fans are not efficient enough with the airflow through your pc. A good thing to know is that the larger the fan in regular circumstances, it will do a better job with noise cancellation and airflow as the fans spin slower than smaller fans. You can adjust this to speed up for better airflow, although it may cause more noise to come from the fan.

How many fans are needed for a pc?

Regularly PC will have 3+ fans that come with the case; however, if you have good fans, you could get away with 2, one for airflow in and one for airflow out. However, this is not recommended as it might not be that good at cooling down your pc.

We would recommend using 4 as a base number. More fans won’t harm the pc. Airflow will be improved by more than 2 fans and will be a good basic foothold on cooling your pc with your fans.
