Ultra-Quiet 140mm fans

140mm fans have enjoyed a massive surge in popularity in recent times, with many case manufacturers now including 140mm fan cutouts as standard. The big advantage of a 140mm fan is that because its blades are larger than any of the other common fan sizes, the fan does not have to spin as quickly in order to produce a given amount of airflow. This means less noise and longer life! With our large range of 140mm fans, there is sure to be a fan to suit any budget and airflow requirement.

Some 140mm fans also have mounting holes which are spaced like those on a 120mm fan and this means that (space permitting) you should be able to use a larger 140mm fan instead of a 120mm fan.

If a 140mm fan does share the same mounting hole positions as a 120mm fan we will mention it in the description of the fan on the actual product page. As a general rule of thumb, 140mm fans housed in a round or oval shaped housing usually have 120mm mounting holes while those in a more conventional square housing will be have 140mm mounting holes. Of course if you are not sure please just call and ask!

To differentiate between standard 3-Pin fans and 4-pin PWM (self adjusting) fans we use PWM in the name of the fan. If it doesn’t say PWM in the name of the fan then it is a standard 3-pin fan.

To convert airflow in cubic feet per minute (CFM) to cubic metres per hour (m³/h), multiply the CFM figure by 1.7.

“Great company, amazing service.”

“Bought a motherboard and cpu fan from Quiet PC, as they were reasonably priced. Was a little unsure at first, as had never heard of them. They have honestly been amazing to work with.

The motherboard had a few technical issues. However they sent me out extra parts free of charge, which arrived the day after I filed a complaint with them.

They were responsive and helpful by email. Item arrived next day each time I’ve ordered, even on their First Class postage option.

Will definitely be using them again, and recommend them to anybody looking for good support when trying your next self build.”
