Dynatron A24 Aluminum Stacked Fin with Heat Pipes CPU Cooler Socket AM4 for 2U

Was having termal issues with nocturna low profile coolers with Ryzen 9 processors like the 5800X. This has very much fixed that issue, and I've tweaked the fan profile in the BIOS to be more agressive. The high RPM fan does a really good job. Also, the termal paste is pre-applied so it spreads properly. I had no problem installing this. Looks like others did but I always install coolers before installing the motherboard so I can get around it. Compared to others, this is a piece of cake. I also like the fact that the fan is side mounted other coolers don't have much clearence from the top of the cooler to the case. I think that helps significantly with air flow. It is noisy expecially with more agressive fan settings but it's in a computer room so noise is not a factor for me.

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!

Does a good job cooling the CPU but it is way too loud. Made PC unusable due to noise level Even at low RPM, the fan is loud Received noise complaints from the neighbors. I'm not even joking. On the upside if you follow the instructions its easy to install and can definitely fit a 2U case You can get a noctua nh-l9 for a few bucks more so i would recommend that

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.

I avoided this for a long time because of the reviews. I was attempting to put a 3800x in a 1U box with a couple different Dynatron heatsinks, 1 passive, and 1 active. There was no way that noise level was going to be acceptable in my house, especially since I had the chip under lower wattage to try and reduce heat. Seated this bad boy and the same hardware in a 2U chassis, reset BIOS to default for CPU voltage and steppings, and everything is perfect. It can get a little loud here and there during the summer heat, but I have it in a pretty full and enclosed rack with not a lot of mesh. In a normal rack with good airflow I don't think anyone would even notice it.

It keeps my cpu cool enough. Nothing special. I just refused to pay outrageous prices for coolers that have and expiration date like closed loop liquid coolers or for expensive ones that can’t justify their price. I only use headphones with my pc and tv nowadays, so it doesn’t make a difference really. My old Alienware pc when it revved up gets louder, but when my gpu kicks in it’s definitely noticeable even over room fans.

This is sooooo much better than noctua heatsyncs. The noctua was running the chip at over 100 c sometimes. This one gets up to around 90 c which is still too high but this is with an AMD Ryzen 3950x with all cores at 100% utilization. For normal usage or even midrange usage this will make your chip last years!

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.
