ARCTIC ACFRE00134A Liquid Freezer III 240 240mm AIO Black CPU Cooler

I use my PC mainly for 3D animation / simulations in Houdini and motion graphics. Ryzen 3900X processor which gets pretty hot with simulations, however the Arctic Cooler does a very good job keeping temps down. PC idles at between 24 - 30 degrees and reaches 84 -87 degrees when doing intensive fluid simulations. I found the best configuration for my setup was pulling air into the case for better temperatures. The cooler fans are set up for pushing air outward by default so just a minor change in fan direction was needed in my case, otherwise installation was easy. Overall very happy with this product.

This is a very nice AIO Cooler if you are looking. What makes it very nice is even the pump that goes on the CPU has a tiny fan for that extra cooling it works like a dream. Just make sure your pc is big enough as it has a pretty big Radiator.

Use case: liquid cooling on media/application server (3900x)

Cooling performance is excellent sitting around 45 C at idle, while maintaining quiet operation while at load with better cooling efficiency
The AMD mount is a bit finicky to install, but how often are you going to be removing the cooler anyway?, so this is a minor gripe.

And of-course the pricing is extremely competitive, I would recommend considering this cooler.

PS. I think Arctic's rads are a bit thicker, so double check compatibility with your set up.
