DEEPCOOL Assassin IV Dual Tower CPU Air Cooler (Black)

The Deepcool Assassin IV is a high-performance dual-tower CPU air cooler engineered for builders who demand effective thermal management without sacrificing acoustics. Its distinctive twin fin-array heatsink design channels airflow efficiently across both towers, working in tandem with a matched pair of fans — a 140 mm unit at the front and a repositionable 120 mm fan at the rear — to maximise heat dissipation across the entire heatsink surface. A hardware performance/quiet mode switch lets you tailor the cooling profile to your workload without entering the BIOS or installing software. In Performance Mode, the fans spin between 500 and 1700 RPM, delivering up to 79.1 CFM of airflow at noise levels of 29.3 dB(A) or below. Switch to Quiet Mode and the fans cap at 1350 RPM, dropping output to a near-silent 22.6 dB(A) — well suited to productivity tasks, media consumption, or overnight renders. Both modes use 4-pin PWM connectors, so motherboard fan headers retain full speed control regardless of the switch setting. The cooler's seven 6 mm copper heat pipes draw heat rapidly from the CPU integrated heat spreader through direct contact and distribute it across the dual fin arrays, where the fans evacuate it from the chassis. Fluid Dynamic Bearing (FDB) fan motors with six-pole construction are specified for low vibration and extended operational life. The 120 mm fan is relocatable, providing clearance for tall memory modules when needed. The Assassin IV ships with Deepcool DM9 thermal paste and a magnetic top cover for clean cable management and straightforward installation. The mounting system supports a wide range of current and legacy sockets.
