DARKFLASH E400 PLUS CPU Heatsink, Black

The DARKFLASH E400 PLUS CPU Air Cooler – Black is a tower-style desktop CPU air cooler that uses four copper heat pipes and an aluminium fin stack to draw heat away from the processor. Two 120 mm PWM fans operate in a push-pull configuration, spinning at 800–2,100 RPM to deliver up to 50.18 CFM of airflow and 1.81 mmH₂O of static pressure. The copper base plate contacts the CPU directly, while the aluminium radiator fins dissipate heat into the chassis. At maximum rotational speed, the fans produce 37.1 dB of noise, making this cooler suited to everyday use, gaming, and demanding workloads where moderate acoustic output is acceptable.

This cooler supports Intel LGA 1851, LGA 1700, LGA 1366, and LGA 115X sockets, as well as AMD AM5 and AM4 platforms, with a mounting kit and CPU brackets included for installation. A built-in dot-matrix LED display provides real-time CPU temperature monitoring directly on the unit, while 5 V 3-pin ARGB lighting connects to compatible motherboards for synchronised illumination. The two fans connect via 4-pin PWM headers, allowing the motherboard to adjust fan speed based on thermal load. Overall dimensions of 122 × 115 × 155 mm mean shoppers should verify clearance against RAM height and side-panel clearance before purchasing.

• Hydro-bearing fans measure 120 × 120 × 30 mm each and operate on a 4-pin PWM connector.
• Thermal detection and speed detection sensors feed real-time data to the integrated dot-matrix LED display.
• ARGB lighting uses a 5 V 3-pin connector at 5 V LED voltage for motherboard-controlled colour synchronisation.
• Static pressure rating of 1.81 mmH₂O suits the push-pull configuration for consistent airflow through dense fin stacks.
• Constructed from copper, aluminium, and plastic, with a dedicated copper base plate for direct CPU contact.
