Cooler Dynatron K2 Processor Cooler 7.5 cm Black 1000-4000 RPM

The Dynatron K2 is a compact CPU cooler designed for Mini-ITX systems. It combines an aluminum blower housing (75 x 75 x 15 mm) with a copper heatsink and a push-pin mounting mechanism, providing targeted cooling for processors with a TDP of up to 73 W. The cooler features a 7.5 cm (75 mm) PWM fan with an adjustable speed range of 1000–4000 RPM, operates at 12 V and delivers a maximum air pressure of 0.929 mmH2O. Its small footprint (82.6 × 81 × 27.8 mm) makes it suitable for tight cases where space is limited.

Advantages

The Dynatron K2 offers a compact design that fits Mini-ITX motherboards while combining aluminum blower construction with a copper heatsink for improved heat transfer. PWM fan control enables dynamic speed adjustment between 1000 and 4000 RPM to balance noise and cooling performance. Push-pin mounting simplifies installation in compatible motherboards and the blower form factor focuses airflow directly through the heatsink for efficient heat dissipation in constrained enclosures.

Suitable for

• Mini-ITX small-factor desktop builds
• Home theatre PCs and compact workstations
• Systems with processor TDP up to 73 W
• Environments where a compact blower-style cooler is required

How to use

Place the cooler onto the CPU socket of a compatible Mini-ITX motherboard and secure it using the push-pin mounting system according to the motherboard manufacturer’s guidance. Connect the 4-pin PWM fan cable to the CPU_FAN header to allow automatic speed control. Ensure the blower outlet is oriented to direct airflow through the heatsink and that surrounding components provide sufficient clearance. Apply thermal paste between the CPU and heatsink if it is not pre-applied.

Recommendations

For best results, use the Dynatron K2 in compact cases with restricted vertical clearance and for processors with a TDP no greater than 73 W. Monitor fan profiles in BIOS or software to balance noise and cooling; periodic dust cleaning will help maintain airflow and performance.
