80mm case fans measure 3.15 inches x 3.15 inches are the most popular fan size for most builds. With an 80x80mm case fan you get good airflow and good noise operation - making these very popular in standard desktop applications. 80mm case fans come in all shapes and colors and the lighted case coolers are best sellers for people who want that 'cool' look to their build.
FAQ & Section Info
What 80mm fan should I buy?
Most 80mm fans are fairly low cost, which means even if you purchase a high-end fan you won't need to spend much cash. You'll be able to choose between PWM fans, LED Lighted fans, and those that combine the two. There are also different kinds of bearings. Some of the more common bearing types are Rifle bearing, ball bearing, SSO bearing, and Fluid Dynamic Bearing. These provide differing lifetime and noise performance, of which usually those that produce less friction have better performance.
Are 80mm fans loud?
80mm fans, like other sized fans have differing noise levels. Noise levels are largely determined by the quality of motor and bearing. Different bearings are more prone to louder noise levels, such as ball bearings, while others, such as Fluid Dynamic Bearing fans, usually remain quieter.
what is the ideal RPM range for low noise operation?
While the fan spin rate isn't the only factor in determining noise output, some people do use the RPM rating to get a sense of how loud a fan "could" be. For low-noise operation we recommend fans in the range of 0 - 1900 RPMs. It's usually a better idea to look at the fan's dBa rating over the spin rate. For that, the lower the rating, the lower the noise level. Shoot for a range between 0 - 25 dBa for low-noise operation.
