Product description
Practical tips
For a desktop PC build that needs temperature-led fan control, the Thermalright TL-C12C X3 connects to a 4-pin PWM fan header. Its speed can respond automatically to motherboard temperature, helping the system adjust cooling as demand changes. Use it as a case fan or alongside a CPU cooler. The silicone corners help reduce vibration where the fan is mounted.
When planning a build, compare the fan’s 120 × 120 × 25 mm size with the mounting space in your case or cooler. The cable supports PWM series fan control, so it can also suit a setup where several fans are managed together. This makes it a practical choice for builds where automatic speed control matters more than selecting a fan by a single fixed speed.
Technical overview
- Type: 120mm computer case cooling fan
- Dimensions: 12L x 12W x 2.5H centimetres
- Connector: 4-pin PWM
- Maximum rotational speed: 1,550 RPM
- Air flow: 66.17 CFM
- Noise level: 25.6 dBA
- Bearing: S-FDB
- Power: 2.4 watts
- Included component: Computer fan
The S-FDB bearing is designed to keep blade movement steady, while the four soft silicone corners help limit vibration and friction during operation. Together with PWM speed control, these features support cooling that can increase when the motherboard calls for it while keeping noise in consideration during everyday use. The stated maximum speed is 1,550 RPM, with airflow rated at 66.17 CFM.
Why it’s worth it
This fan brings several useful details together for a PC cooling setup: a standard 120mm format, 4-pin PWM control and an S-FDB bearing. Rather than choosing a fan only for a fixed speed, you can connect the TL-C12C X3 to a compatible motherboard fan header and let its temperature-based control adjust rotation. That is useful for a system whose cooling needs vary between lighter tasks and more demanding operation.
The vibration-reducing silicone corners add a practical touch for case installation, and the fan can also be used with a CPU cooler. For a build that needs a replacement case fan or an additional cooling point, its stated airflow and automatic PWM control offer a clear basis for choosing it. It suits you if you want a 120mm fan that can be managed by the motherboard rather than adjusted only by hand.
Questions before you buy
How does the fan control its speed? Connect its 4-pin PWM cable to a compatible motherboard fan header. The motherboard can then adjust fan speed in response to its temperature readings, up to the stated maximum of 1,550 RPM.
Can it be used with a CPU cooler? Yes. It is described for use as a case fan or with a CPU cooler, where it can contribute to the cooling setup.
What size is the fan? It measures 12L x 12W x 2.5H centimetres, also stated as 120 × 120 × 25 mm. Check that the mounting position in your case or cooler accommodates this size.
Final verdict
The Thermalright TL-C12C X3 is a considered fit for desktop PC builders who want motherboard-controlled cooling in a 120mm format. Its 4-pin PWM connection, S-FDB bearing and vibration-reducing silicone corners make it well suited to case airflow or use alongside a CPU cooler.
