Fans in the tech world have several uses. They are mandatory because they keep the CPU cool. They have applications in low-profile cases, heatsinks, and coolers. Regular fans are around 25mm thick and consume a standard amount of space. But there are 15mm variations known as the slim 120mm fans that are smaller and do not need so much space. If that’s what you are looking for, this article will interest you.
Best Slim 120mm Fan – Buying Guide
PC fans are not like ceiling fans except for the fact that they cool the atmosphere they are in. PC fans are not generic. They are made specifically for certain computers or CPUs and you should buy one accordingly. To find the best slim 120mm fan, here are the factors to keep in mind:
- Check the connector type – there are 3-pin and 4-pin connectors. Of course, adapters are available to interchange but it’s always a good idea to buy a fan that’s directly compatible.
- You will need a good fan case for your slim 120mm fan. There should be enough room to allow the blades to spin freely.
- See if you prefer high static pressure or high airflow. They both serve different purposes.
- Choose a fan that has good quality ball bearings. The cheaper ones usually compromise on this aspect, leading to problems in the long run. Fluid bearings are the best, but they are also expensive.
- If you prefer, you can also choose fans with LED lights.
