Works so well, I had to slow the fans down.
I just upgraded from a 120 mm water cooler to this 240 mm model. For reference, my processor is rated at 125 W. I purposely picked the same brand cooler with the hopes that the mounting would be identical. For my socket, this unit requires the factory mounting bracket that many other coolers, including my original cooler, do not use. It is a simple process to install, if the bracket is already on the motherboard. Otherwise, you have to find one. Luckily, they are under $10 to replace, if missing. Performance wise, I had my old cooler from the factory constantly running at 100% fan speeds to maintain decent temps. This new cooler is so efficient that I had to reduce the fan speeds to keep the temps above ambient levels. (Can’t drop below ambient in Florida unless I want a wet processor.) At constant 100% fans, this new cooler dropped my temps to below 20° C. With the motherboard now in control and adjusting the fan speed, I am about 30° C at idle and peak in the 40’s with moderate activity. This is about a 10° C drop from my old cooler for idle temps. I am not a gamer so I rarely push the processor too hard. Video production is the main thing stressing the system and that only happens in bursts. Based on some other reviews, I used a name brand thermal paste instead of what came with the cooler. I don’t know how much that changes things. The setup works great so I like it. Also, important to note that the factory paste originally installed was still extremely wet so it had not dried out. For whatever reason, the old setup was just not keeping up with the heat being generated. If I am hearing the pieces correctly, the fans are extremely quiet and I hear a little bit of pump noise. Since I am always wearing headphones, I don’t hear anything with them on. The RGB system works, but seems to have extremely limited options. I wanted a decent, budget cooler, more than lights, so I am happy with the product.

The Cooler is a Significant Improvement over the OEM CPU fan and easy to install
Personal Experience: After my wife made a comment on how loud the OEM CPU fan was for my desktop I decided it was time to get a liquid cooled replacement. I wanted something that would not only be quieter but keep my CPU cooler. Read some reviews and I was between the 120mm and 240mm radiator, I settled on the 240mm radiator because my case had the space and for the price it was a good deal. Install of the cooler is relatively easy if you have experience building computers or swapping out components and your case has room to accommodate the radiator and cooling tubes. My setup uses an AMD chipset but the cooler accommodates both AMD and Intel chipsets; the directions are easy to follow on how to install for either style. Make sure you clear cables out of your way with Zip ties and ensure that everything fits before you bolt/strap it down. If you are upgrading your existing CPU Fan/Cooler I would suggest purchasing good thermal paste remover so you can start with a clean surface. Overall it took me about 45 minutes to remove the old fan, clean off the thermal paste, layout the new Cooler setup then bolt everything down/apply new thermal paste. The lights on the cooler are a nice touch. All in all I was pleased with CPU cooler upgrade from install to performance. Recommend: Yes Pros: Far quieter than the OEM fan that came with the CPU Easy to install in a large case Came with all the mounting equipment you would need Lights are a nice touch to customize your setup Works with both AMD and Intel chip sets (AMD on my setup) Cons: Will not fit in a smaller case (did not affect me but be aware) Installation Suggestions: If you are upgrading get thermal paste remover and be generous when cleaning the CPU Layout everything before you tighten everything down; I had to move the radiator slightly to get everything to fit nicely Read the directions on which way to install the fans the first time (I have installed fans backwards before and it sucks)

This thing is good!
I used this with a Ryzen 2600x CPU and added 2 fans to it to make it a push pull, Works amazing compared to the stock AIO cooler in my other ryzen 2700x from Cyberpower, that is only a single radiator push pull.... That one sucks compared to this guy!!!!! Keeps my CPU very cool. I have not had one power failure due to CPU overheating on this system.. But my other 2700x with the single overheats all the time. I actually had to downclock it, I am thinking about getting another one of these for that one as well, but I would have to dismantle a lot of stuff to make it fit as it would only fit my case in the front.... and the lights on it are cool... I did not like the clamps for the motherboard though.... they were rather tricky and flimsy..... just be careful, be calm, and do it when rested on a clear head.... do not attempt to install if frustrated.

Lo compré sin darme cuenta que no embonaba en mi gabinete y tuve que usar el disipador que viene en el procesador (Ryzen 2600x) pero este hacía demasiado ruido y se calentaba bastante, entonces adapté el gabinete para que entrara y ha sido una maravilla, poco ruido a comparación de antes y se mantiene a muy buena temperatura. Es la primera computadora que armo y no tuve ningún problema para armarlo, las instrucciones son claras.

Really nice cooler keeps temps nice and cool fans are a little loud and the radiator came with a couple dents also only way I found of changing colours is with little remote as I could not find no software to use even the ones it says is compatible with don’t seem to work but all that a side really good cooler would give 5 star.

before using this radiator i was using the i71c fan also from coolermaster on my i5 9600k and i got 90-100 C on rainbow six siege after using the radiator i got 70-85 c but no difference in idle temp installation was also a pain as i could only mount it on the front of my case

Este me gusto mas ya que es de una buena marca y no es caro como otros, funciona de maravilla en my ryzen 5 2600, en idle la temperatura ronda los 36 a 38 grados Celsius, jugando no pasa de 46 grados Celsius, en 100% de uso no pasa de 60, los ventiladores no acen mucho ruido, ya llevo usandolos durante casi 3 meses y no e tenido ningun problema
