What to look for in a 120mm case fan
If you’re in the market for a case fan, consider these specs as you’re browsing.
- Bearing format: Consider the more durable magnetic levitation bearings, or the more common hydraulic bearings.
- Size: Check your case’s parameters to confirm you have the right case fan diameter.
- Compatibility: Size is one consideration, but also be sure your PC case has the slots you need for the case fans you’re buying.
- Static pressure or RPMs: Check that the fan can efficiently vent and dissipate heat.
- Design: Check out the variety of colors, and add some RGB for flashier builds.
Is a 120mm case fan the best choice for your build?
To answer the question of which format of case fan is best for your build, you’ll want to look closely at all your cooling components and what you’re hoping to accomplish. That 120-millimeter measurement refers to the size of the fan itself, so a larger number will more easily move air. However, it’s important to look at the thickness of the unit as well as confirming that your case can accommodate the size of fan you’re looking for. From there, you’ll want to look closely at the RPMs, static pressure count, and whether the bearing mechanism employs hydraulic lubrication or magnetic levitation technology.
