Cooler Master Hyper 620S Dual Tower CPU Air Cooler, ARGB Sync, 120mm PWM Fan

I've been using the Cooler Master Hyper 620S for almost two years now, and it continues to deliver excellent performance. This dual-tower air cooler features six direct-contact copper heat pipes and two PWM fans that keep my CPU temperatures low, even under heavy loads. It's impressively quiet even during gaming or stress tests, the noise level stays minimal. The power consumption is also very efficient, with each fan drawing only about 3 watts, making it a great choice for energy conscious users. The 154.9 mm height fits well in most mid-tower cases, though it's worth noting that high profile RAM might have clearance issues. Installation was straightforward, and the ARGB lighting syncs nicely with my motherboard, adding a clean, modern look to my build. Overall, it's a reliable, quiet, energy efficient cooler that I highly recommend.

This cooler.master is a beast looks good cools good and I like that it came with installation instructions. The temperature is much cooler, and so far so good I highly recommended.

One of, if not the best cooler I've ever owned. I'm not a fan of liquid cooling products and I think Cooler Master makes some of the best products.

I purchased this unit for an older I7-8700K machine I found for cheap and made it into a project after the mounting on the Noctua fans I got on that machine broke. It was cheaper to replace the fan rather than look up the mounting kit, which for that Noctua setup seemed impossible to find. I then opted for this unit as the reviews claim that it was keeping their systems cool Two days later I got it and went to install it. The mounting kits are all included. This comes with a PWM header splitter for both fans in case your MB does not have two headers for fans. It also comes with aa 4 pin RGB header connector for 5V. Fans are mounted properly and silent. However the RGB would not sync up with my MB and other components. The RGB would not align with the other components. I asked amazon for a replacement and got it fast. I then setup the lights on and no fans on and tested. This worked. So I went ahead and set it up again. To my surprise the RGB colors are no longer matching again. I decide ok I will take off the RGB headers. Well guess what, the RGB lights still come on. That is when I realized that the fan spinning made it to where the RGB lights did not sync. I then unplugged the fans to the MB header and realized that they no longer sync. Long story short, I used the Noctua fans from the one I had got on my system and attached them to this. IDK if I was unlucky and got 2 sets of bad RGB lights and fans but it makes no sense as to what I encountered. If you buy these and are using a mother board that has rgb memory, rgb motherboard lights, rgb exhaust fan and rgb front fans and think that this will sync, it may not. Note that my RGB exhaust fan also spins and syncs with all other components. Just my experience with this fan.

This cooler works very well to keep my cpu running cool. When I am running cinebench the cpu reaches a maximum of 75c, and in games the cpu barley reaches 70c. Along with how well this cpu performs it also looks really nice. The only downside that I have with this cooler is that one of the fans hangs over my ram sticks, so I cant see one of the sticks. However that is a mionor issue as the performance of the coooler is worth no seeing one of the ram sticks.
