Thermaltake TH420 V2 Ultra EX ARGB AIO CPU Cooler/Water Block 2.1" LCD/Fan 140 * 3/Magnetic Quick Connection/MB ARGB Sync Control/LCD Software Control/CL-W417-PL14SW-A

Great AIO keeps my Ryzen 7 9800x3d very cold, quiet, and looks nice with many options for the LCD screen.

Works, technically. But there are tons of forum posts about the USB-A slot going bad and I've experienced this myself. I have to prop the cable with some pressure for the software to see the device in Windows and to keep the data flowing to the LCD screen on the AIO. Bad design and poor quality on this part. Well known issue. Went bad within 6 weeks of owning and never moving or touching the cable or PC itself. That being said, the cooler is extremely quiet and keeps my 7950x3d very cool even under full load and gaming loads. I've stressed tested the CPU for 12+ hours and checked the logs. Eventually I'll replace it with a different manufacturer as this is a common problem for this one. Sad quality and design for the price.

I used this AIO for a Thermaltake Tower 300 Build and although I had read some preview reviews criticizing the unit, I have found that it works without any issues. I run an AMD Ryzen 9 7950X3D and in serious gaming sessions, my CPU hovers around 61C max. The only small issue I have found is that the Thermaltake software, TT RGB, is a bit fiddly, nothing huge, just some minor occasional glitches, which are very easy to correct. I opted to replace the stock fans for the Thermaltake SWAFAN EX14 RGB PC Cooling Fan TT Premium Edition 3 Pack, for aesthetics. See my review for those too. Took off one star for the software implementation.

Great aio. Instructions in box were limited but it’s quiet and I’m shocked with how cool my case is now.

Aio works, pump works, fans work, however tt software is a different story. It doesn't see its own fans to control fan speed or rgb. Second, it only would recognize the lcd screen sometimes, a quick fix is to swap usb headers on the motherboard but to experience it again later. Thermaltake has a nice feature with magnetic fan connection, but falls short and their software needs lots of love to work correctly.
