Clyxgs Water Cooling Radiator, 8 Pipe Aluminum Heat Exchanger Radiator with Fan for PC CPU Computer Water Cool System DC12V 80mm Black

Using it for my 50W CO2 laser. It makes a huge difference keeping the laser tube well within temp limits. The fans are very quiet providing enough cooling for this application. I would buy this again.

Low noise, high efficiency unit. Great value.

This is built just like a big automotive radiator, except tiny. It doesn't have massive airflow, but I personally think the fan should face the other direction (sucking air through the radiator, rather than pushing it). I reversed mine, anyway. If you have the space, you might want a bigger radiator/fan for most applications, but if space is an object (as in my application), this radiator/fan may be just the ticket. UPDATE June 2024: I initially got the little 80 cm radiator/fan to cool an array of 22 power diodes carrying about 6 A each, with a about 200W of waste heat. I later added 22 power MOSFETs to that array, upping my heat dissipation to around 250-300W under peak load, resulting in a water-to-air temp differential of about 15C. The little radiator/fan did fine until I got into the middle of a recent heatwave. Ambient heat in the garage was about 38C, so the heat sink was running at about 53C - a bit warmer than I wanted. Having changed the form factor of my equipment housing, I now had the room, so why not? I bought the 240 cm, double-fan radiator. Like before, I reversed the fans to draw air, rather than pushing it. My temperature differential is now down to about 3.5 C, and the semiconductor array is very happy. The big double-fan radiator is made to the same construction standards - good flow, no leakage, etc. The 120mm fans I received seem to be sleeve-bearing fans, unlike the ball bearing 80 cm fan I got last year. Of course they are easily replaced when the time comes. The little 80 cm fan put in a good 6-8 hr per day for nearly a year with no complaints I've set it aside for another future project.

work great, using 2 in a 4x8 room to cool a cellar on a glycol chiller and fan controller. have to be creative to fab a bracket to mount these, would be nice if they came with something or even tabs to bolt up to.

a lot bigger than what I expecting, but it does that work

After 9 days fan burned up.

Only had this up and running a few days but satisfied to date. Because it is 12 volt, I had to convert my 110 Ac to 12V with small charger. Don’t need the yellow wire for this purpose, just use black as neg and red as pos. Important to use tester to insure you don’t have reverse polarity. I may come back in a few months to update.

I used this product for my water-cooling loop, and I used it to cool my phone. I was concerned that, since it was 80 mm, and not 120, that the water cooling loop that I had made for my phone and laptop wouldn't cool down when I was hitting it with a heavy load, like gaming. However, I was floored when it not only managed to keep my temps on my phone and laptop down, but also be nearly silent as I used it, while being less than half of the price of a combined radiator and a noctua fan.
