CWWK Jonsbo HP400S Low-Profile CPU Cooler
JONSBO HP-400S Low-Profile CPU Cooler
Compact cooling designed for space-conscious PC builds. The JONSBO HP-400S combines a 36.7 mm low-profile design, four copper heat pipes, and a 90 mm PWM fan for efficient heat dissipation in Mini-ITX PCs, HTPCs, and compact desktop systems.
Compact Design. Efficient Cooling.
Engineered for compact computer systems, the HP-400S features a top-down cooling structure that combines effective heat transfer with controlled airflow. Its low-profile construction makes it suitable for space-limited builds where cooler clearance is an important consideration.
Four Copper Heat Pipes
Four 6 mm copper heat pipes transfer heat from the CPU contact surface to the aluminum cooling fins.
90 mm PWM Fan
A hydraulic-bearing fan with 4-pin PWM control operates at 900–2800 RPM ±10% to adjust cooling performance.
36.7 mm Low Profile
The compact cooler height is designed for Mini-ITX, HTPC, and other low-profile computer builds.
Installed on CWWK CW-M2
The following images show the JONSBO cooler installed on the CWWK CW-M2 NAS motherboard, illustrating its installed position and the space occupied by the cooling assembly.
Important: Check Case Clearance
When installed on the CWWK CW-M2 motherboard, the JONSBO cooler may extend beyond the motherboard edge.
If you plan to install the CW-M2 motherboard and JONSBO cooler inside a computer case or custom enclosure, please check the total dimensions of the assembled motherboard and cooler before selecting the chassis.
The cooler's standalone dimensions are 103 × 92 × 36.7 mm. These measurements do not represent the overall dimensions of the assembled CW-M2 motherboard and cooler.
