Dynatron Intros A49, a Dual Fin-Stack, 4U-compatible Socket AM5 CPU Cooler

btarunr · Feb 21, 2023

Dynatron focuses on server/workstation cooling solutions, and developed the A49, a Socket AM5 cooler with a dual aluminium fin-stack heatsink that's designed to work with 4U rackmount cases, although it will fit inside ATX tower cases just fine, with its 130 mm height. Two dense aluminium-alloy fin-stacks are skewered by six 6 mm-thick copper heat pipes that make direct contact with the processor over a high-performance thermal pad. The heatsink is ventilated by a custom 103 mm x 103 mm x 30 mm fan that turns at speeds of up to 1800 RPM, pushing up to 35.03 CFM of airflow at 28.8 dBA noise output, and 1.16 mm H₂O static pressure. Dynatron says the cooler can handle thermal loads of up to 170 W. The cooler measures 95 mm x 95 mm x 130 mm, weighing 710 g.

Fan seem quite underpowered for rack use, was expecting to see 3000+ RPM fan.

Nice industrial cooler. I would put 3 - 92mm fans on that badboy.

It's direct contact.That is paste or something.

That’s what I thought, too, but, at least according to dynatron, it does have an aluminum base

Yeah I was excited and went and looked at the spec sheet. Like why they gonna cheap on that?

Look at my Noctua NH-D15S. Same design which gives superior air cooling. Can improve by adding a secondary fan like the OG D15.

The pipes sit in an aluminum base but that pic looks like paste cause you can see clean aluminum on the sides and the center is dirty paste.

Here is a pic of the A39 on amazon, so there you are.
