Doesn’t do the job for a ryzen 3950C

This doesn’t do the job for a ryzen 3950X. Stressing the CPU with stress -c 2 causes cpu throttling within seconds.

Careful, only one orientation. Not really suitable for ryzen 3000-series.

Reviewed in the United States on 1 September 2019

Verified Purchase

The concept is sound but the implementation sucks pretty badly. I can only give it two stars.

First, note that the orientation only gives you front-to-back airflow if the motherboard is oriented that way in the 2U case. Insofar as I know, there is only one motherboard that might have that orientation (out of dozens)... the (fairly low-rent) ASRock Rack motherboard. So that's a problem right there.

Second problem are the screws. The two screws nearest the fins are slightly underneath the fins. Completely ridiculous, Dynatron could trivially have given proper clearance for those screws. The other two screws are under the fan, but the fan is fairly easy to remove (and comes un-assembled) so those two aren't really an issue.

The third problem is the contact area for the CPU. Dynatron is striping aluminum and copper (the four heat pipes are flush to the cpu contact area, but embedded in the aluminum so its striped). This means that the heat-takeaway is going to be uneven and while that would have worked just fine with the Ryzen 2000 series CPUs, it's a freaking disaster for a Ryzen 3000 series cpu.

These three issues severely limit the use cases for this cooler.

Works, but it's a nusiance to install

Reviewed in the United States on 15 April 2019

This is probably one of the few realistic options for SFF cases with tight clearances to the power supply. The stock Wraith cooler for the Ryzen 7 2700 is tall enough that it is fighting with power supply for air intake.

As noted by others, the fins overhang the mounting screws on one side. Buy a long #1 precision Philips head screwdriver BEFORE attempting to install. Anything else will drive you crazy trying to use without chewing up either the fins or the head of the screw.

Seems like a 5mm shift to one side in the design would make a huge difference in usability.

Works great...

Like I said in the headline, the CPU cooler works great. I run these on my 2U servers with my Ryzen 7 processors.

Juan's review before mine was correct as far as installation. It's a pain due to the location of the mounting screws. This is my reason for 4 stars instead of 5 stars. Other than that, it does work great.

Awesome!

Reviewed in the United States on 13 July 2019

Awesome! Cooler keeps my ryzen 2700 VERY cool!!! This is the only AM4 2U cooler I could find so I'm glad it works phenomenally well! The fan is quiet too when correctly setup with PWM control. The other reviews are correct though... Mounting it is a pain! Short lived frustration was worth the great performance though!

Surprisingly Powerful

Reviewed in the United States on 17 April 2019

I built a 2U PF-Sense router using a Ryzen 3 2200g this keeps it just slightly above ambient with the fan barely needing to run. I plan on using this on a low profile build with a Ryzen 7 2700. I hope it works as well on the high end as the low.
