All inclusive

The budget tower cooler provides a high heat dissipation rate of 250 W, so it copes well with cooling high-performance processors from Ryzen 5 / Core i5 and higher. The kit includes mounts for all popular sockets from AMD and Intel. The installation is double-sided (backplate), so that the heavy weight and dimensions of the active cooler do not create an excessive load on the motherboard. The manufacturer uses an aluminium heatsink with a high plate density and four heat pipes that are in direct contact with the processor to improve heat transfer.

Full automation

The main cooling force is a 120mm fan. The connection is made via a 4 pin connector with PWM support, which allows the system to operate in automatic mode - the speed depends on the temperature sensors on the motherboard. Despite the use of a hydrodynamic bearing, the noise level reaches 37 dB, which is quite high and can create discomfort at night. If necessary, the fan can be replaced.
