  • Active cooler design delivers reliable airflow for sustained operation

LGA 4189 Server Cooler

The Dynatron N11 is an active air cooler built for Intel Whitley platform processors using the LGA 4189 socket. It targets Ice Lake and Cooper Lake server CPUs in 2U and larger chassis. Buyers needing a cooler for different sockets or lower-profile 1U systems should look elsewhere.

205 W Thermal Capacity

Rated to dissipate up to 205 watts of CPU heat, the cooler uses an aluminum stacked-fin array with embedded copper heat pipes. No fan-speed curves, acoustic measurements or power-draw figures are supplied, so exact noise and thermal behaviour under load cannot be quantified.

Compact 2U Form Factor

The unit measures 4.45 by 3.23 by 2.60 inches, fitting standard 2U server heights. Its integrated fan and fixed mounting simplify installation in compatible racks, but the dimensions restrict use in tighter enclosures or non-standard layouts.

Questions about this item

How do I install the N11 on an LGA 4189 socket and which step is often missed?

Mount the cooler using the four captive screws that align with the LGA 4189-4/5 socket holes; the step often missed is tightening them in a diagonal pattern to ensure even pressure across the copper heat pipes.

What maintenance will the N11 need over its service life?

Periodically clean dust from the aluminium fin stack and verify the fan spins freely; the embedded copper heat pipes and aluminium fins require no fluid replacement or re-greasing.

What thermal limit appears first when the N11 runs at full load continuously?

The cooler is rated for 205 W heat dissipation; sustained loads above that level will cause CPU temperatures to rise beyond safe operating limits.
