be quiet! Silent Loop 3 Liquid CPU Cooler Review

April 14, 2025

Final Thoughts on the be quiet! Silent Loop 3

With this being our first AIO to be tested on the new system, performance compared to other coolers is still up for debate. That said, the CPU never came close to reaching its thermal maximum of 95C, even when under full load and at our lowest fan setting of 500 RPM. When taking into consideration idle and load temperatures, as well as noise output, I found that the 1,000 RPM fan speed resulted in the most balanced mixture. There was only a few degrees of difference between the range of temperatures, all well below the thermal limits of the CPU, while the noise output above 1,500 RPM just didn’t justify the cooling.

As far as looks go, I think the vertical RGB lighting section is very attractive, and can certainly be disabled if lights aren’t your thing. Aside from the lighting, there isn’t much flair to this cooler, as the all-black design provides a pretty stealthy look to the overall appearance of the Silent Loop 3.

Available for $164.90 from our favorite online retailer, and most likely not positioned to see any price increases for US buyers due to tariffs, I think the be quiet! Silent Loop 3 provides a nice mix of aesthetics, cooling performance, and acoustic output that many system builders will find appealing. The tried and true Silent Wings 4 fans are certainly top-notch, and the included coolant bottle will have you using this cooler for years to come, with a 3-year warranty to step in if ever needed. As the sole cooler to gauge performance from on our new test system, the overall rating for the Silent Loop 3 may adjust in the future if deemed necessary. So with that in mind, the be quiet! Silent Loop 3 earns a 9 out of 10.
