Developed with Synergy Cooling

Unique design of Fera 5 heatsink and tailored fan have been developed in cooperation with Synergy Cooling. Designed in tandem, main components of Fera 5 have a synergistic effect on performance.

Check Fluctus 120 PWM

Fera 5 is a new SilentiumPC CPU cooler implementing Synergy Cooling technology. It’s an all-new, asymmetrical heatsink with densely packed fins, optimized heatsink base and four direct-touch heatpipes, combined with new Fluctus 120 PWM fan with improved bearing and excellent acoustics. In addition to single fan Fera 5, a twin fan Fera 5 Dual Fan model with 2× Fluctus 120 PWM fans is available. Fera 5 series coolers are covered by 6-year manufacturer warranty.


High performance, long life Fluctus 120 PWM fan

Fluctus 120 PWM works best on dense heatsinks and water cooling radiators, where airflow is restricted. Uniquely profiled fan blades create high static pressure. New high endurance bearing ensures smooth, low noise operation with 100 000 h MTBF.

Excellent acoustics

Serrated leading edges of fan blades contribute to noise reduction. This reduces prominent tonal noises and is at heart of our patent-pending psychoacoustic optimization.

Fan stop - optional semi-passive mode

Fluctus fans stop at very low PWM duty cycle and start automatically with rising duty cycle. Enthusiasts can create an optional semi-passive operation mode by adjusting the fan speed control curve.

Asymmetrical heatsink

Heatsink fins are asymmetrical and specially profiled for maximum performance and minimum noise. Install with the indicated airflow direction for best results.

Direct touch heatpipes

The compact heatsink base provides the best contact with the surface of modern CPUs. Four heatpipes are in direct contact with the CPU to improve heat transfer.

Easy mounting system

New, universal mounting system improves contact pressure between heatsink base and the processor. It has fewer parts and is easier to install in any position. Included pictorial manual and video guides explain the installation step-by-step.

6 year warranty

High quality and durability of FDB bearing together with Fluctus 120 PWM fan IC is confirmed by long, 6 year warranty covering entire Fera 5 cooling solution.

Pactum PT-3 thermal compound

Bundled thermal paste has high thermal conductivity and low viscosity. Pactum PT-3 combines high performance with ease of application. Bundled amount is sufficient for more than 3 applications.

    Caution! HE technology (direct contact between heatpipes and CPU) requires using dense thermal compound, like the one included in the package. Thermal compounds applied with brush are too thin and may affect the cooling performance unfavourably.

    Please DO NOT use ‘liquid metal’ type thermal compounds such as Coollaboratory Liquid Pro/Ultra, Thermal Grizzly Conductonaut Liquid Metal, etc. with this product, as they will corrode the aluminium part of the base. All the complaints regarding corroded heat sinks will be rejected.
