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 .


This fan is designed with PWM function, and full speed will apply when pluged into 3 pins instead of 4 pins .
The TY-149 can be pluged into the old 3 pin socket; you can tell from the jack, there is fool-proof design on the jack so wrong installation of the pins are avoided .
Please first refer to the Support FAQ when using your Thermalright PWM fan on your mainboard’s Chassis_Fan Socket.
