GN Case Testing Bench (Sponsored by CableMod) SB601 at 83% fan speed with front panel removed, equalized to stock SB601 at 100% (36dBA).RL06 w/2x Silent Wings 2 140mm front fans (taken from SB601) replacing 3x stock Silverstone 120mm front fans, all fans 55%, equalized to SB601 at lvl 1 (32.9dBA).RL06 at 36% front 40% rear fan speed, equalized to SB601 at lvl 1 (32.9dBA).RL06 at 58% fan speed, noise equalized to SB601 at 100% (36.1dBA).Silent Base 601 at fan controller level 1 32.8 dBA.Silent Base 601 at 100% fan speed 36dBA.The entire process followed the normal review process (pasted methodology below, just in case you need it), but the change is that we were focusing on normalized noise for this one. Testing was a bit different from what we normally do.
It comes with two Pure Wings 2 140mm fans, one configured as front intake behind a steel panel and foam layer, and one as rear exhaust.
Meanwhile, the SB601 maxed-out at 36dBA, or 32.8dBA with the integrated fan controller turned down to the minimum speed. It has three 120mm front intake fans behind a mesh panel and a filter and one slower (and therefore quieter) rear exhaust fan. In its original review, we measured the RL06 at 43dBA with the fans running at 100%. For today’s testing, we are entirely focusing on noise level at 20” and testing thermals at normalized volumes. For the most part, noise damping foam addresses concerns of high-frequency whines and shorter wavelengths, while thicker paneling addresses low-frequency hums and longer wavelengths. Volume is one thing, but the frequency and subjective annoying-ness matter too. One variable that we aren’t equipped to measure is the type of noise. The RL06 is one of the best-ventilated and noisiest cases we’ve tested in the past couple of years, while the SB601 is silence-focused with restricted airflow. The candidates chosen as a case study were the Silverstone Redline 06 and the be quiet! Silent Base 601. Our thesis for this benchmark paper proposes that fans can be turned down sufficiently to equate noise levels of a silence-focused case, but while still achieving superior thermal performance. Instead, most users would likely turn down the fans to an acceptable noise level-maybe even the same level as intentionally quiet cases like the Silent Base 601. The baseline torture tests are good for consistency, showcasing maximum performance, and for highlighting the performance differences between cases, but they don’t represent how most users run their PCs for 24/7 usage. Our testing tends to reinforce that idea of a choice: our baseline results are measured with the case fans at maximum speed and therefore maximum noise, making cases like the SilverStone RL06 sound like jet engines. The reality is that it doesn’t have to be a choice, and that an airflow-oriented case can, with minor work, achieve equivalent noise levels to a silence-focused case (while offering better thermals). We tend to prefer high airflow to silence when given a choice, and it usually is presented that way: as a choice. These often include specially designed fans, thick pads of noise-damping foam, sealed front panels, and elaborately baffled vents. I have it housed in a 2U case but the case fans on the case itself isnt quiet as its a cheap case and its 2U.Respected manufacturers of silence-focused PC cases like be quiet! and Fractal Design use a number of tricks to keep noise levels down. I even have 1U and 2U compatible scythe CPU fans and are totally silent while being able to cool a 1st gen iseries 6 core xeon thats overclocked to 4 Ghz so i dont really need typical desktops. Noctua fans arent the quietest actually, scythe makes good silent fans. Make sure the case is light as well or you will end up regretting in the future. The smaller the case you can get the better but make sure they only have big fans as the lower RPMs doesnt make as much noise. My silent case is the akasa venom, good for my needs as i have many PCIe cards, eatx motherboards, drives and i tend to have the swap things around. The silent one is easy to operate with while the noisy one is difficult to handle drives and much heavier. one is totally silent and has at least 10 PCI slots while the other only has 7 PCI slots and is very noisy despite both cases being the same size.
