Two-Fan ARGB Pack for 120 mm Mounts

This Thermaltake CT120 ARGB Sync pack supplies two 120 mm case fans with hydraulic bearings and 9 addressable LEDs each. PWM control covers a 500 to 2000 RPM range, delivering 57.05 CFM airflow at 25.8 dB-A. A daisy-chain design reduces cable count and the anti-vibration mounts simplify installation.

Builders Wanting Synchronised Lighting

The 5 V ARGB header sync works with compatible motherboard software for 16.8 million colour options across both fans. Users who need a single fan, a different frame size, or non-ARGB operation will not match this kit’s specifications.

4-Pin PWM Plus 3-Pin 5 V ARGB Connector Pair

Each fan requires both a 4-pin PWM header for speed control and a 3-pin 5 V ARGB header for lighting. Systems lacking either header type cannot run the fans at their full specified capability.

Questions about this item

Will the 120 mm by 25 mm frame fit my standard case fan mounts?

Yes, the 120 x 120 x 25 mm dimensions match the common 120 mm mounting pattern used on most cases and radiators.

How do I connect the 4-pin PWM and 3-pin ARGB cables for daisy-chaining both fans?

Plug the first fan’s 4-pin PWM into a motherboard fan header and its 3-pin ARGB into a 5 V addressable header, then link the second fan to the first using the supplied daisy-chain connectors.

When should I expect the hydraulic bearing to need replacement?

Hydraulic bearings typically run for many years; if noise rises above the rated 25.8 dB-A or RPM drops below 500, the fan should be replaced.
