be quiet! Shadow Rock 3, BK004, 190W TDP, CPU Cooler, HDT Technology

SummaryPROS-Completely silent at low loads, reasonably quiet at max fan speed-5 to 10 degree Celsius improvement over stock AMD Wraith Stealth cooler (for Ryzen 5 3600)-Relatively easy installation-Well packaged-All required tools and mounting hardware included - even a screwdriver-You can add another fan if you really wanted to-No clearance issues with I/O shield or tall RAM-Minimal aestheticsCONS-AMD mounting instructions could use refinement and diagrams that don't show the Intel bracket-Easily bent fins-Fan doesn't have sleeved cablesNEUTRAL-Very tall - check your case clearance before buying-One color option-No RGB optionI purchased this cooler to replace the stock Wraith Stealth cooler that came with my Ryzen 5 3600. While the stock cooler offers good enough performance for daily use and gaming, its high-pitched noise and small fan size gave it a very intrusive acoustic profile (translation: loud and annoying).In looking for a CPU cooler, I wanted a unit with high acoustical efficiency - the quietest possible unit that could still keep my CPU at reasonable temperatures that wouldn't cause throttling under normal loads (so under ~80 degrees Celsius).I had high hopes for the be quiet! Shadow Rock 3 cooler based on reviews, and I have to say it met and even exceeded all expectations. With the same fan curve from my stock cooler, it is completely silent under everyday use (60% PWM at idle/low-load temperatures) and dropped idle temps by around 5-10 degrees Celsius. When gaming, I can't hear it over my GPU fans (EVGA GeForce 1660 Super), and my CPU maintains the advertised boost clock. Even if I manually turn up the fans to the fastest speed, it's still reasonably quiet and is low pitched enough as to not be intrusive. be quiet! includes mounting hardware for a second fan should you want to do a push-pull setup, but I honestly can't see why you would unless you were seriously pushing a higher-end CPUFor $50, the only real complaints I have are that there aren't other color options (e.g.: all black or all white) or RGB options, and the AMD mounting instructions need refinement. The instructions tell you how to attach the mounting bracket to the motherboard, but then proceeds to show an Intel bracket when telling you how to mount the tower cooler. Additionally, the instructions tell you to mount the cooler on top of the CPU before putting on the screws and screwing them in. If you follow that step, as I did, you'll find that there is no room to squeeze the screws in under the large tower and will end up having to take the cooler off first, which is frustrating.

Purchased this to revamp my older liquid cooler due to noise. Works great on my i7 8700k CPU. Didnt have to remove MOBO, and installation was strait forward. Along with case fan replacements, my PC is really quiet, and it cools my CPU with ease. i7 8700, 1080ti GPU.

I upgraded all my fans on my home machine to "be quiet" fans and have used many of their products over the years. 4 years in on an AMD 3950X and this does better than a lot of air coolers that cost a lot more and also the big thing, I have installed several of these and never had a problem with ram clearance on ANY full atx board amd or intel and that's a big thing. No RGB but you cant see this machine anyway since I have to have a full metal case so I didn't want it and could care less. To me pc's should not be seen or heard. Changed all the case fans over from stock to the "be quiet" fans and most of the time you wouldn't know its running and that was the goal. I have also used their cases which are just as wonderful. If your not looking for flashing lights you cant get much better for the money and the heatsink itself is extremely well built and designed. Cools better and faster than most of the typical stand up radiator coolers out there and is capable of twins in a push-pull but you wont need it. If your an extreme over-clocker then your looking at water anyway and wouldn't want this but for a tame high end machine this will surprise you. As always DO YOUR HOMEWORK FIRST AND KNOW WHAT YOU NEED AND HOW YOU PLAN TO USE YOUR MACHINE. No device made will work well if you don't understand what your needs are first.

First off, was recommended by Micro Center so that should tell you you’re in the right place. Second after setting the bios to the recommended settings for my cpu I found on YouTube and then doing a multi core stress test, it didn’t even break 70°C 👍ALSO THE SCREWDRIVER IT COMES WITH IS GOD TEIR, I WILL BE USING THAT BABY ON ALL FUTURE PC BUILDS.Note: I am not overclocking. My case is a mid-tower (a bit on the smaller side), and, excluding the heatsink fan, has a total of 2x 140mm fans (intake, default motherboard controlled) and 4x 120mm fans (outtake, 1 motherboard controlled, other 3 default lian li fan settings).
