Dynatron Q3 1U Server Active CPU Cooler — Intel LGA1851 / LGA1700 | 80mm PWM Fan | 125W TDP

The Dynatron Q3 is built for 1U rackmount server builds, enterprise workstations, and high-density compute deployments where ultra-low profile CPU cooling is mandatory within strict 1U chassis height constraints. It is well-suited for Intel Core 12th, 13th, 14th, and 15th Gen server and workstation platforms in LGA1851 and LGA1700 socket motherboards, data centre rack deployments, edge compute nodes, and industrial systems requiring reliable 24/7 continuous operation under controlled thermal conditions.

The Q3 features a copper heatsink with skiving fin construction, providing a large and highly conductive surface area for rapid heat transfer away from the CPU IHS under sustained server workloads. The 80mm PWM dual-ball bearing fan delivers wide dynamic speed control from 1000 RPM at low duty cycle for near-silent idle operation, to 7000 RPM at full duty cycle for maximum airflow of 22.28 CFM and 74.18 mm-H2O static pressure under heavy thermal loads, enabling precise, demand-driven cooling across all workload types. Dual-ball bearing construction ensures the fan operates reliably over 70,000 continuous hours at 40°C ambient temperature — a critical requirement for always-on data centre and server environments. The compact 92×90×28mm overall footprint and 28mm total height make it purpose-built for 1U server chassis where vertical clearance is extremely limited. M3 screw-type installation with a recommended torque of 5–7 in-lb ensures secure, consistent CPU cooler mounting in professional server assembly. Full 4-pin PWM control allows server management platforms and BMC controllers to dynamically manage fan speed in response to CPU thermal data for optimal noise-performance balance.
