Thermalright TL-B14015 Extrem 140mm Slim 2600RPM Case Fan
The Thermalright TL-B14015 Extrem 140mm Slim 2600RPM Case Fan is a 140 mm fan only 15 mm thick. It spins up to 2600 RPM and moves up to 92.3 CFM with 2.01 mm H2O of static pressure, on a dual ball bearing with a 4 pin PWM connector.
The slim frame suits builds where a standard-thickness fan won't fit, such as tight spots between a radiator or cooler and the case wall. The high top speed suits builders who want strong airflow under load, and PWM control lets the fan slow down and run quieter when the system is idle.

Compatibility and related parts
Check that your case or cooler has 140 mm fan mounts, and that your motherboard has a 4 pin PWM fan header or that you have a PWM hub or splitter. You can find those among our PC build accessories. If you are planning a full system, the PC builder checks compatibility, and parts bought as part of a PC build get free assembly and testing. You can also compare airflow options in our PC cases or see other Thermalright products.
