Dynatron A35 80mm Dual Ball Bearing PWM CPU-ilmajäähdytin AMD EPYC SP3/TR4

In dense server racks and workstations built around AMD EPYC SP3 or TR4 sockets, the Dynatron A35 keeps sustained multi-core loads within thermal limits. Its 80 mm dual ball bearing fan pushes up to 68.4 cfm at 3800 RPM, while the copper base and aluminum fins pull heat away from the CPU. Three speed settings let you balance cooling performance and noise from 16 dB to 48.8 dB.

Key specifications

• Socket compatibility: AMD EPYC SP3, TR4
• Fan diameter: 80 mm
• Fan speed: 800–3800 RPM (3 speeds)
• Airflow: 68.4 cfm
• Static pressure: 0.4–10.1 mmH2O
• Noise level: 16 dB (low) / 48.8 dB (high)
• Bearing type: dual ball bearing
• Fan connector: 4-pin PWM
• Base plate material: copper
• Heat sink material: aluminum fins

Why choose it

The dual ball bearing design extends service life in 24/7 operation, and PWM support allows the motherboard to adjust fan speed dynamically. The 80 mm form factor fits 2U server chassis where larger coolers cannot.

Ideal use cases

• AMD EPYC SP3 servers and workstations
• TR4 socket builds requiring high static pressure
• Rackmount systems with limited clearance

Good to know

The cooler includes a mounting kit for SP3 and TR4 sockets. It operates at 12 V DC with a maximum power draw of 4.8 W.
