Ruth's sister W12E12BS11B5-57 120x120x38mm 12V 1.65A 4-pin internal power cable

Ruth's sister 120×120×38 mm 12 V 1.65 A Fan

This Ruth's sister cooling fan measures 120 mm by 120 mm with a 38 mm thickness and runs on 12 V DC drawing 1.65 A. It uses a 4-pin PWM connector for automatic speed control and is built with dual ball bearings for continuous operation. The unit is supplied new and ready for installation in compatible chassis or heatsink mounts.

Suited for 4-pin PWM headers and high airflow needs

Builders with a standard 4-pin PWM header who need high-speed airflow in a 38 mm thick frame will find this fan matches their requirements. Buyers whose motherboard or controller only provides a 3-pin voltage-regulated header cannot use the PWM function. Systems that require a slimmer profile than 38 mm or a different voltage input should look at alternative cooling options.
