Fractal Design's Radius 360 RGB Cooler Launches
Fractal Design launches its 2026 Radius 360 RGB AIO liquid CPU cooler. The 360mm unit has a redesigned pump, integrated cabling, and costs $109.99.
Fractal Design has introduced its new Radius family of all-in-one liquid CPU coolers. The flagship Radius 360 RGB, a 360 mm model, is positioned as the successor to the company's previous Lumen S36 RGB V2 cooler.
According to a review from Guru3D, the Radius platform represents a substantial update, not just a visual refresh. It incorporates a new pump and block assembly, new Dynamic 3 fans, and cleaner cable management. The cooler is available in 240 mm and 360 mm sizes, with or without addressable RGB lighting. The black color is offered across the range, while white is exclusive to the 360 mm RGB version.
Design and Installation
The Radius 360 RGB uses a 394 by 120 by 27 millimeter aluminum radiator connected by 400 millimeters of tubing. Three Dynamic 3 fans come pre-mounted to the radiator, which the review states reduces installation time and cable clutter. A key design feature is the routing of wiring alongside or through the cooler's tubing, which cleans up the visible area around the CPU socket.
The pump assembly features a copper cold plate and a ceramic bearing. Its speed is rated at 3400 RPM with PWM support, a change from the Lumen cooler's 4000 RPM pump that lacked PWM control. Fractal Design specifies a maximum pump pressure of 2.1 meters of water for the Radius, compared to 1.8 meters for the Lumen.
Compatibility and Control
Socket support focuses on contemporary hardware. The Radius cooler supports Intel LGA 115x, 1200, 1700, and 1800-series sockets, along with AMD's AM4 and AM5. Mounting hardware is included and thermal paste is pre-applied.
The RGB version integrates with Fractal Design's ARGB Gen 2 lighting and Adjust Pro, a web-based interface for controlling lighting, fan speeds, and pump flow rate. This requires an internal USB 2.0 connection and SATA power.
Pricing and Market Position
The suggested retail price positions the Radius 360 RGB as an aggressive option in the 2026 market. The review from Guru3D provides the following breakdown of U.S. pricing for the Radius line.
| Model | Price |
|---|---|
| Radius 360 RGB (Black/White) | $109.99 |
| Radius 360 (Black, no RGB) | $99.99 |
| Radius 240 RGB (Black) | $99.99 |
| Radius 240 (Black, no RGB) | $89.99 |
The $109.99 price for the flagship 360 mm RGB model includes three pre-installed fans, PWM pump control, integrated cabling, software control, and a five-year warranty. The pump is rated for 40,000 hours of operation at 40 degrees Celsius. The review notes this is a reduction from the Lumen's 50,000-hour rating, though both products carry the same five-year warranty.
Fractal Design has kept the product line focused, opting not to produce a 280 mm model. The company's goal appears to be delivering a thoughtfully modernized cooler without the premium of LCD-equipped models. Its performance will ultimately depend on thermal and acoustic testing.
