Dynatron L40 liquid cooler for AMD SP6/TR5

The Dynatron L40 is an all-in-one liquid cooler built for AMD SP6 and TR5 sockets. It supports up to 350 watts of heat dissipation and fits 2U server chassis and larger. The unit includes Shin-Etsu 7762 thermal paste pre-applied for immediate installation.

Suited for high-density server builds.

This cooler targets integrators assembling 2U or taller rack servers on the AMD SP6/TR5 platform. It is not designed for consumer desktop sockets such as AM5, nor for chassis smaller than 2U. Buyers needing a cooler for workstation towers or custom loops should look elsewhere.

350-watt thermal capacity and 2U form factor

The decisive specification is the 350-watt dissipation rating combined with a 2U-compatible height. Verify that your server CPU TDP stays within this limit and that the rack provides at least 2U of vertical clearance before selecting this cooler.

Questions about this item

Which Dynatron L40 variant matches my 2U server chassis?

The cooler is built for 2U and taller racks, so the single 16 x 5 x 12 inch unit fits directly.

What does the 350 W rating mean once the cooler is installed?

It guarantees dissipation of up to 350 watts from an AMD SP6 or TR5 processor under load.

How does the 4-pin PWM connector limit control options?

The 4-pin header lets the motherboard vary pump and fan speed up to 8000 rpm automatically.
