Dynatron CPU Liquid Cooler L3-UH 1U for Socket 115X/2011/1356/1366/1700/AM4/AM5, noise 19.35 dB

Dynatron L3-UH is a 1U liquid CPU cooler developed for low-profile and space-constrained systems. It supports a wide range of Intel and AMD sockets including 115X, 2011, 1356, 1366, 1700 and AM4/AM5, providing a compact cooling solution for server blades, HTPCs and small form-factor PCs. The unit is engineered to fit into 1U chassis layouts while maintaining liquid cooling efficiency and a published acoustic level of 19.35 dB.

Advantages

The Dynatron L3-UH combines a low-profile radiator and an integrated pump to deliver effective heat transfer in restricted spaces. Its compatibility with multiple mainstream Intel and AMD sockets reduces the need for separate models for different platforms. The specified noise level of 19.35 dB makes the cooler suitable for quiet environments, while the liquid cooling design improves thermal stability compared with many air-only solutions in similar form factors.

Suitable for

• 1U server blades and rackmount systems where vertical clearance is limited
• Home theater PCs (HTPC) and media centers requiring quiet operation
• Small form-factor desktop builds with constrained internal space
• Workstations or embedded systems that need consistent cooling under sustained load

Key specifications

• Form factor: 1U low-profile liquid cooler
• Socket compatibility: Intel 115X / 2011 / 1356 / 1366 / 1700; AMD AM4 / AM5
• Acoustic level: 19.35 dB (published)
• Cooling type: closed-loop liquid cooling with integrated pump and radiator
• Intended installation: horizontal/low-clearance chassis environments

How to use

Install the Dynatron L3-UH following the chassis manufacturer’s instructions for 1U cooling solutions and the cooler’s mounting hardware. Position the radiator and fan assembly to match airflow direction inside the chassis and secure the pump block onto the CPU socket using the provided bracket compatible with Intel 115X/2011/1356/1366/1700 or AMD AM4/AM5. Connect the pump and fan power leads to appropriate motherboard headers or power sources, verify secure fittings and clearances, then power up the system and check for normal pump operation and stable temperatures before regular use.

Usage recommendations

Ensure chassis airflow is sufficient for a 1U layout and route cables to avoid obstructing the radiator or fan. Verify BIOS/UEFI fan and pump control settings to maintain the intended balance between noise and cooling performance. Regularly inspect external fittings and mounting points during scheduled maintenance; since this is a prefilled closed unit, avoid attempting to open or refill the loop.
