Intel Core i5-9400 Processor The Intel Core i5-9400 is a 9th Generation desktop processor built on the Coffee Lake architecture. Designed for mainstream gaming and productivity, it features 6 physical cores and 6 threads (lacking Hyper-Threading) with a base clock speed of 2.9 GHz and a maximum Turbo Boost frequency of 4.1 GHz.

Fabricated on a 14nm process, the chip includes 9 MB of Intel Smart Cache and supports DDR4-2666 memory in a dual-channel configuration. It has a Thermal Design Power (TDP) of 65W and integrates Intel UHD Graphics 630, eliminating the need for a discrete GPU for basic display output. The processor utilizes the LGA 1151 socket (300 series chipsets) and supports technologies like Intel Optane Memory and Virtualization (VT-x/VT-d).

DeepCool GAMMAXX GT RGB CPU Cooler The DeepCool GAMMAXX GT RGB is a single-tower air cooler engineered to combine efficient thermal performance with aesthetic customization. It utilizes four 6mm direct-contact copper heat pipes that transfer heat directly from the CPU to the aluminum fin stack, ensuring rapid dissipation for processors with TDPs up to 150W (Intel) or 140W (AMD).

Cooling Performance and Design The cooler is equipped with a 120mm PWM fan featuring Hydraulic Bearing technology, which offers a balance of longevity and quiet operation. The fan speeds range from 500 to 1650 RPM, delivering a maximum airflow of 64.5 CFM while maintaining noise levels as low as 27.8 dB(A). The hydraulic bearing design reduces friction and vibration compared to traditional sleeve bearings.

RGB Lighting and Compatibility Aesthetically, the GAMMAXX GT features addressable RGB lighting on both the fan blades and the brushed aluminum top cover. Users can synchronize lighting effects with compatible motherboards (via 3-pin 5V ARGB headers) or manually control colors and modes using the included wired controller.

The cooler supports a wide range of sockets, making it an ideal match for the Intel Core i5-9400:

Intel: LGA 1151, 1150, 1155, 1200, 1366, 2011, 2066. AMD: AM4, AM3+, AM3, AM2+, AM2, FM2+, FM2, FM1. With a total height of approximately 157mm, it fits most standard mid-tower and full-tower cases, providing robust cooling headroom for the i5-9400's 65W thermal output.
