## Long description

The Jonsbo HP-400S 9 cm air cooler with hydraulic bearing is a compact CPU cooling solution designed for small to mid-size desktop systems. Its 9 cm fan offers a balance of airflow and low noise, while the compact dimensions (103 mm width, 92 mm depth, 36.7 mm height) allow installation in constrained cases and on motherboards with limited clearance. The black finish provides a discreet, neutral aesthetic that integrates with a range of PC builds.
Advantages
The hydraulic bearing fan reduces operational noise and improves longevity compared with sleeve-bearing designs. The compact form factor supports installation in compact enclosures and low-profile builds without sacrificing basic cooling performance. The cooler’s straightforward design simplifies mounting and maintenance while the 9 cm fan delivers focused airflow over the heatsink fins for effective heat dissipation from mainstream CPUs.
Suitable for
Small form-factor desktop PCs and HTPC systems
Systems with limited CPU cooler clearance
Office and home computers where low noise is important
Builds requiring a discreet, black cooling solution
Key specifications
Fan size: 90 mm
Bearing type: hydraulic bearing
Dimensions (W × D × H): 103 mm × 92 mm × 36.7 mm
Color: black
How to use
Mount the cooler on a compatible CPU socket following the motherboard and cooler manufacturer instructions. Ensure the mounting bracket is properly aligned and secured to provide full contact between the heatsink base and the CPU heatspreader. Connect the fan to the CPU fan or system fan header on the motherboard to allow automatic speed control. Periodically inspect the fan and heatsink for dust accumulation and clean with compressed air while the system is powered off.
Usage recommendations
Place the cooler so that its airflow aligns with the case airflow path for optimal heat extraction; avoid obstructing the fan intake with cables or other components. For systems with high thermal load, consider case airflow improvements or a larger cooling solution.
