## Summary description

The DeepCool ASSASSIN 4S is a high-performance air cooler featuring a 14 cm fan with a maximum airflow of 61.25 CFM. It utilizes Fluid Dynamic Bearing technology for quiet operation and durability. With dimensions of 147 mm width, 116 mm depth, and 164 mm height, it fits most cases. The cooler offers excellent cooling efficiency with a minimum air pressure of 2.46 mmH2O and a maximum of 3.76 mmH2O, making it ideal for high-performance CPUs.

## Long description

The ASSASSIN 4S is a high-performance CPU air cooler featuring seven 6mm heat pipes and a redesigned 140mm FDB fan. The 4S removes the rear 120mm fan for a slimmer, more symmetrical cooler that maintains strong cooling capacity while improving RAM clearance and overall compatibility.
Advantages
The cooler offers two operating modes—quiet and performance—selectable with a slide switch to prioritize low noise or maximum cooling. Its streamlined shell directs airflow efficiently through dual fin towers, and the recessed central 140mm fan increases airflow to nearby VRMs. Three-phase, six-pole low-voltage fan motors ensure silent operation with low power consumption. The package includes industrial-grade DM9 thermal paste and a magnetic top fan cover to simplify installation.
Key specifications
 Model: ASSASSIN 4S
 Heat pipes: 7 × 6 mm
 Fan: 140 mm FDB (center)
 Fan configuration: single central 140mm (no rear 120mm)
 Operating modes: Quiet / Performance (switch selectable)
 Included thermal paste: DM9
 Warranty: 6 years (limited)
How to use
Mount the cooler to the CPU following the included bracket and manual for your socket type. Apply a thin, even layer of the supplied DM9 thermal paste on the CPU heatspreader before seating the cooler. Connect the fan to the motherboard CPU fan header, then select Quiet or Performance mode using the slide switch depending on whether you prioritize low noise or maximum cooling. Ensure the magnetic top cover is attached after installation to help direct airflow.
Recommendations
For optimal results, verify clearance for tall RAM modules and ensure good case airflow. Use Performance mode for intensive CPU workloads and Quiet mode for everyday or noise-sensitive use. Follow the manual for mounting steps and torque guidelines to avoid mounting damage.
