Koeler Inter-Tech A-38 processor 6 cm zwart

The Inter-Tech A-38 Processor 6 cm Black is a compact CPU cooler designed for high-rotation cooling in constrained spaces. It integrates a 60 mm fan with a rotational speed range from 2,300 to 11,000 RPM and a reported maximum air pressure of 28.8 mmH2O. The cooler uses a ball bearing fan for extended operational life and presents a black finish in a small footprint measuring 119 mm (width) × 65 mm (depth) × 79 mm (height), weighing 0.45 kg. It is compatible with high-end and workstation sockets including sTRX4, TR4 and SP3, making it suitable for multi-core processors in compact or specialized builds.

Advantages

The A-38 combines a very high maximum fan speed with a compact form factor, which helps deliver concentrated airflow where space is limited. The ball bearing fan construction provides improved durability and stable operation over extended periods. With a specified high air pressure value, the cooler is capable of forcing air through dense radiators or heatsink fins and can be effective in setups that require directed cooling performance. The black design fits a wide range of system aesthetics without adding visual complexity.

Suitable for

• Small form-factor workstations using Socket sTRX4, TR4 or SP3 processors
• Systems where space constraints limit cooler dimensions
• Setups requiring high static air pressure for targeted heatsink or radiator cooling
• Builds that prioritize a compact, black-colored cooling component

How to use

Mount the cooler according to the motherboard and processor socket instructions, ensuring compatibility with Socket sTRX4, TR4 or SP3. Position the unit to allow unobstructed airflow and secure it to the processor or bracket with the supplied mounting hardware. Connect the fan power cable to the appropriate fan header on the motherboard or fan controller, observing correct voltage and control settings. Verify clearance around nearby components to prevent contact with cables or memory modules given the cooler's compact dimensions.

Recommendations

For optimal performance, use the A-38 in systems where high RPM and air pressure are needed within a small volume. Ensure the fan header and BIOS or fan controller can accommodate the wide RPM range and adjust fan curves to balance noise and cooling. Periodically clean the fan and heatsink surfaces to maintain airflow and inspect the ball bearing for signs of wear in long-term deployments.
