DeepCool Castle RGB 280mm TR4 CPU Cooler Review


Castle 280 TR4

We’re no stranger to CPU cooler reviews here at eTeknix, but today, we’re breaking from our usual methods. The DeepCool GamerStorm series of coolers has a focus on cooling some of the most extreme CPUs on the market today. A while back, we took a look at their Fryzen ThreadRipper CPU cooler, which you can read here. However, if you’re more interested in liquid coolers than air coolers, the new Castle 280 RGB is just the ticket.

The Castle comes equipped with a 280mm radiator, dual 140mm RGB fans, and their massive pump that’s perfectly suited to Threadripper (TR4 socket) CPUs from AMD. What’s better is that since we cannot compare this with our usual cooling test bench results that use an Intel CPU, we’ve got two Threadripper CPUs to test. We put the Castle on both chips while running our CPU review tests, giving us the perfect opportunity to sneak in a cooler review at the same time.

Product Trailer

What’s in the Box?

Quite a lot actually, starting with both AMD and Intel mounting kits and ending with both a 3-port fan hub and an RGB controller module for those without controls on their motherboard/chassis. It’s a pretty complete package and means both new and old systems can take full advantage of all the lighting and fans in the box. The fans are very nice quality too, with custom shaped fins to better direct the airflow. There are also anti-vibration mounts on the corners.

As a child still in my 30's (but not for long), I spend my day combining my love of music and movies with a life-long passion for gaming, from arcade classics and retro consoles to the latest high-end PC and console games. So it's no wonder I write about tech and test the latest hardware while I enjoy my hobbies!
