Creality Water Cooling Kit for High-Temp 3D Printing, Leak-Free and Silent Water Cooling Solution, Compatible with Ender 3 S1 Pro, Ender-5 S1, CR-10 Smart Pro and 3D Printers with Sprite Pro Extruder

From the first day I bought the Ender, I suffered through constant problems related to temperature and different materials. It was a wonderful day if I could print two parts in a row to completion, and printing something for more than a few hours was just miserable as I knew it would fail sooner or later. Hundreds of hours of calibration, alignment, temperature selection and all possible guides are now in my past - not a single case of temperature-related problems after installation. It is an unreasonably expensive upgrade, but it works even without modifications and installs without having to do anything. Just attach according to the instructions, fill with liquid, run the pid calibration and you're done.

Let's start with the o-ring that wasn't properly installed on one end of the main reservoir tube. I had already expected the heatsink to leak, but not the main tube from not being screwed together correctly. Then there is the fact that this says water cooling and you can't use water. Just say liquid, which isn't included. That's another $20-30. This unit doesn't have an active cooling component, either. The heatsink portion attached o the reservoir doesn't give me confidence for higher temps because of this. My last complaint is the bracket to holds the reservoir to the printer broke after lifting it one time while troubleshooting the above issues. Given that computer water cooling has been around for many years, I think the above issues should've been addressed in the design phase.

Product does as advertised. My cooling block weeps. This was immediately after install and fill. Photo attached.

Wasn't expecting the amount of heat it actually removes. In FDM Printing, it is about keep things hot and cool right next to each other. The closer, the better. In the thermal image, you see the head glowing red/yellow. Above it, you can see how cool the water cooler keeping the head (blue). The second heat spot, on the left, is just the frame getting warm being an inch or so away. impressive. For the water cooler, I'd suggest a fan to cool it. Check Thingiverse, they have a fan hood you can print.

I like the design but if they can't be bothered to seal it shut I can't recommend it. Took me way too long to determine I didn't screw up installing the hoses. If you buy definitely set up outside your system to test for leaks first.

I like it I just wish it came in blue or black. But I had an issue with it leaking and the seller replaced it for me. I'm happy with it

Works well, it's silent which was my main concern. Heat sync could be better quality. The install instructions typical Chinese translation. Just says no water use coolant but doesn't say what kind. I used Evans.

Its pretty nice probably over kill but if you print softer tpu it might keep you out of the heat creep problems
