1U Server Liquid Cooler

The Dynatron L25-1 is an all-in-one liquid cooler built for 1U server chassis. It supports Intel LGA115x and LGA2011/2066 Square ILM sockets alongside AMD AM2, AM3, AM4, FM1 and FM2 platforms. The unit handles up to 250 Watts of heat dissipation for high-density deployments.

Installation and Clearance

Five 40 mm PWM fans mount directly to the radiator for a compact assembly that fits tight 1U spacing. Pre-printed Shin-Etsu 7762 thermal compound removes the need for manual paste application. Builders must verify motherboard keep-out zones and bracket alignment before securing the cold plate.

Sustained Load Behaviour

Under continuous load the five fans can spin to 12000 RPM to maintain coolant flow across the radiator. PWM control adjusts speed dynamically as thermal demand rises. The 250 W dissipation rating reflects steady-state capacity rather than a short burst figure.

Questions about this item

How do I confirm the pump and fans are running at the rated 12000 RPM after installation?

Connect the PWM headers, power on the server, and verify fan speed in BIOS or IPMI; the pump runs continuously when the CPU is powered.

What comes in the box and do I need separate mounting hardware for LGA2011 or AM4?

The cooler ships with the cold plate, radiator, five 40 mm PWM fans, and Shin-Etsu 7762 compound pre-applied; mounting brackets for LGA115x, LGA2011/2066 square ILM, AM2/3/4 and FM1/2 are included.

Which version should I choose for a 250 W CPU in a 1U chassis?

The L25-1 is the single model rated for 250 W dissipation in a 1U form factor; no other capacity or height variants exist.
