Corsair Hydro X Series, XR5 420mm Water Cooling Radiator (Triple 140mm Fan Mounts, Easy Installation, Premium Copper Construction, High-Quality Polyurethane Coating, Integrated Fan Screw Guides) Black

I dropped the XR5 240mm into a secondary loop where space was tight, and it handled the job like a pro. The 30mm thickness paired with a premium copper core and 25-micron fins gives it solid thermal transfer—temps stayed stable even under load. It’s not a monster like the XR7, but for a dual 120mm setup, it punches above its size. Installation was smooth thanks to the integrated fan screw guides, and the matte black polyurethane coating looks sharp without drawing attention. Standard G1/4" threads make it easy to integrate with existing fittings, and the build quality feels premium despite the compact form. If you’re building a smaller loop or need a reliable radiator for a GPU or CPU segment, the XR5 240mm delivers. Just don’t expect it to cool an entire high-wattage rig solo—it’s a team player, not a solo act.

If you like a while radiator look then this will make your pc look awesome. They are really good quality and do help cool your pc like it should. They have lasted a long time in my computer build with no issues. No leaks and the coating is tough which I like.

Works great, have 2 on my gpu loop and maintain about 40°c

These rads are the best for the price!!

Came in great condition. No damage, clean inside as well. I did rinse it. Fits well and does the job. I have 1 in my build now. I would be careful when using the 2 sets of long screws. The longer ones can damage the fins on this puppy, with certain fan thickness. Good stuff overall though.

I have an i7 10700k, and a PNY RTX 3080. During gaming or eth mining VRAM temperatures could rise up to 100 degrees celsius. With two 360mm slim radiators, an XD5, and a water block for the 3080 installed in my system the VRAM averages about 74.9 degrees celsius now. While my GPU temp goes up to about 41 degrees celsius. When not gaming or mining, temps are at 21 degrees celsius for the GPU and 30 degrees celsius for the VRAM. My CPU is at around 51 max, and 36 degrees celsius at idle. These work great for a parallel setup because their resistance is pretty similar to the CPU and GPU water block resistance. This was my first liquid cooling build and I was nervous, but it was really similar to working on a car cooling system, and using an air pressure tester from EKWB made leak testing great. Tried my best to hide the soft tubing, but I think the computer looks a lot better and performs a lot better. Update 3/25/21: The Corsair Commander Pro I have doesn't seem to work properly with the temperature sensor, so I just plugged in the XD5 pump into the AIO header on my mobo. Averaging about 37 degrees celsius on my 3080 and GPU memory junction temperature averages 77.3 degrees celsius now during ETH mining and gaming. CPU basically stays at 30 to 45 degrees celsius during load. Great radiators, kind of wish I got the thicker XR7, but can always add it in the future.

I've used this as a intermediate radiator (middle of loop) between the CPU/GPU to bleed off a little heat before connecting back to loop. Worked great, in my loop config, GPU saw a 1to2c drop
