Key features
Today’s review will introduce you to the CPS RZ620 cooler from the Asian company PCCooler, which is the first product of this company that is about to hit the European market. This cooler falls into the premium class and thus should offer high cooling efficiency. However, it should be available at a relatively low price and thus offer an interesting price-performance ratio. I am therefore curious to see how it performs in stress tests.
Conclusion and evaluation
So, another very interesting cooler is coming to the European market, offering solid cooling performance, high-level workmanship and all this at an affordable price. The supplied fans are slightly noisier than would be desirable, but with proper regulation they don’t stray too far from the normal average.
Out of curiosity, I also tested the CPS RZ620 with a pair of the high-end Noctua NF-A12x25 fans, which resulted in only a very slight improvement in overall performance, but the acoustic response of the cooler was significantly more pleasant. So there is certainly room for acoustic optimization here. The presence of a speed controller, which instead of regulating the speed range locks the fans at a fixed value, seems a bit unnecessary. Personally, I rather recommend not to use it and rely on automatic speed control using the PWM signal from the motherboard.
Apart from minor shortcomings, I was satisfied with the CPS RZ620 cooler overall. Compared to its established European competition, it offers virtually the same cooling performance, but at a lower price. I can therefore recommend it without any qualms and look forward to testing other products from this company.
Where to get your hands on this cooler? For example on Amazonu (for 69,90 EUR).

Now that we can see how well the F5 R120 performs, it would seem that the passive components of this cooler have lots of room for improvement.
Who knows to what extent the efficiency of this is dependent on the platform used. PCCooler claims that the RZ620 cooler is downright optimized for LGA 1700. The emphasis they place on this aspect is almost “fanatical” (in the best sense of the word, no pejorative). So it’s possible that this cooler will end up in a relatively lower placement on platforms other than LGA 1700. However, we can neither confirm nor deny this responsibly from our data. Anyway, this is probably something to be aware of when evaluating a heatsink.
