Overview
Key Features
Great Thermal Image Test Result: Compared to the standard case fan, the combination of three Ring radiator fans and RL360 radiator delivers 40% better cooling performance. (Inlet and outlet temp. are 49℃ and 44.5℃ in respective, △T= 4.5℃). Air flow - 51.15 CFM. Noise level - 24.1 decibels
Concentrated Compression Blade: Custom designed for high-static pressure requirements of demanding applications like radiators, the CCB is engineered to focus the inner circle of air outwards, allowing the outer section to pressurize and compress.
Wind Blocker Frame: To achieve maximum static pressure in all applications, this reduces the blade's noise and vibration, creating a perfect balance between power and sound by creating a compression effect and blocking any pressure from escaping.
Hydraulic Bearing with Low-Noise Design: The hydraulic bearing self-lubricates with a high quality, friction-reducing substance which lowers operating noise. The LNC (Low-Noise Cable) can reduce the noise level by 21% from 28.1dBA to 22.1dBA.

Pros & Cons
👍 Pros
- High-static-pressure blade design is well suited for radiator cooling applications
- Included low-noise cable adapter allows a 21% reduction in operating noise
- Distinctive circular blue LED ring provides clean, even illumination
- Wind Blocker Frame reduces vibration and prevents pressure from escaping
- Hydraulic bearing promotes quiet operation and long service life
👎 Cons
- LED color is fixed to blue with no RGB or color-change options
- Does not include PWM speed control, relying instead on a manual LNC adapter for noise reduction
- At 24.1 dBA full speed, it is not the quietest 140mm fan available
- Only available as a single fan per package, requiring multiple purchases for radiator setups
Frequently Asked Questions
What size radiator or case fan mount does the Thermaltake Ring 14 fit?
It is a 140mm fan, designed to fit standard 140mm fan mounts and radiators.
Does this fan come with a low-noise cable adapter?
Yes, an LNC (Low-Noise Cable) is included, which reduces noise from 28.1 dBA down to 22.1 dBA — a 21% reduction.
What type of bearing does this fan use?
It uses a hydraulic bearing that self-lubricates with a friction-reducing substance for quieter, longer-lasting operation.
Is this fan optimized for use on radiators or as a general case fan?
Its Concentrated Compression Blade design is specifically engineered for high-static-pressure applications like radiators, though it also works well as a case fan.
What is the airflow rating of this fan?
The Ring 14 delivers 51.15 CFM of airflow at a noise level of 24.1 dBA at full speed.
