SKU CH-S4DD-TTS9J MPN 672042302758

A 2U active CPU cooler for LGA3647-0 sockets with an 8400 rpm PWM fan rated at 52 dB

  • 8400 rpm fan speed delivers high airflow for intensive Xeon workloads
  • 52 dB noise level keeps server acoustics manageable in dense racks
  • 4-pin PWM connector enables precise speed control matched to thermal demand
  • 36 in height fits standard 2U chassis without clearance issues
  • Designed for LGA3647-0 socket and Supermicro X11DPL-i motherboard compatibility

Socket LGA3647-0 cooler for Xeon servers

The Supermicro 672042302758 is a 2U active CPU cooler designed for Socket LGA-3647 processors. It targets system builders and integrators assembling rackmount servers on compatible Supermicro X11DPL-i motherboards. The unit provides direct thermal management for Intel Xeon Scalable processors in space-constrained chassis.

8400 rpm fan delivers 52 dB(A) acoustic output

The integrated fan spins at 8400 rpm and produces a noise level of 52 dB(A) under normal operation. A 4-pin PWM connector allows the motherboard to modulate fan speed based on processor load. The 2.36-inch square footprint and 0.98-inch depth fit the thermal envelope of a standard 2U rackmount form factor.

Aluminium fin stack with four-pin PWM control

The cooler uses an aluminium fin stack mounted on a base that contacts the LGA3647-0 socket. Its 2.36-inch width and height match the keep-out zone around the socket on supported boards. The 4-pin PWM header enables automated speed curves without manual adjustment. Builders needing larger radiator surface or lower acoustic signatures should evaluate alternative thermal solutions.

Questions sur cet article

How do I mount this 2U active cooler onto an LGA3647-0 socket and which step is commonly missed?

Align the four captive screws with the socket's mounting holes, then tighten them in a diagonal pattern; the step often missed is connecting the 4-pin PWM header so the 8400 rpm fan reports speed correctly.

What maintenance will this cooler need after extended use in a server chassis?

Expect to clean dust from the 0.98" deep fin stack and replace the 8400 rpm fan when bearing noise exceeds the rated 52 dB(A) level.

At what point does thermal throttling appear first during sustained loads with this 2.36" high cooler?

The 52 dB(A) acoustic limit is reached before thermal headroom runs out, so fan-speed caps or chassis airflow become the first bottleneck.
