Thermalright TY-140 PWM

PWM fan, provides simple and easy adjustment of fan speed with the latest ETC IC. Seven Silent Torpedo Blades - “submerges”, gives most quiet and efficient airflow Enhanced Hyper-Flow Bearing (EHFB) - to ensure consistent and stable rpm, prolonged lifetime of usage. Aerodynamic body–Less friction around the edges and give more centered and concentrated airflow. 12 cm mounting hole–allows installation on the 12 cm dimension, so will be compatible with most coolers without having the need to buy extra kit for 14cm fan. The TY-140 can be pluged into the 3 pin; you can tell from the jack, there is fool-proof design on the jack so wrong installation of the pins are avoided. This fan is designed with PWM function, so full speed of 1300rpm will apply when pluged into 3 pins instead of 4 pins .
