The better approach is to set a fan curve that is flat for most of the temperature gradient (idle and normal loads), sharply increases as the temperature gets to the top end of the gradient (high load), and also resists changing in response to small/brief fluctuations in temperature. In practice this leads to fans ramping up and down a bunch, and the resulting pitch and volume changes of the fan noise is highly noticeable (and irritating) to most people. This isn't actually very good, because temperatures can fluctuate quite a lot in a short period of time. By default, most computers are set up to use a standard linear fan "curve", which basically means that the fan speed increases at the same rate as the temperature increases, in a straight line. But if you wanted a smaller case, or one with fewer mesh/perforated panels, you could try to compensate by adding more/bigger fans and/or a bigger AIO, for example.įinally, there's also one other factor to consider, which is fan curves. The best case scenario (get it) obviously involves a large case with lots of perforations, lots of (big, high quality) fans, and a large heatsink or radiator. Overall, achieving a quiet machine essentially involves adjusting and trading off these factors to achieve the lowest possible fan RPMs, which equates to less noise. And for radiators specifically, a bigger radiator can obviously accommodate more/bigger fans, so the above principles for fans also apply here. A larger heatsink or radiator can both absorb more heat before becoming "heat soaked" and (usually) has a larger surface area to more quickly dissipate heat. AIOs) from where it can be more effectively dissipated into the surrounding air. Heatsink/radiator size: Coolers work by transferring component heat into a heatsink (air coolers and GPU coolers) or a radiator (water coolers incl.Quality of fans: To a certain extent, higher-quality fans can be quieter at the same RPMs than lower-quality fans, and they tend to use PWM for speed control, which allows for more precise speed adjustment (and lower RPMs) than with cheaper DC fans.Or, alternatively, a bigger fan can run at lower RPMs than a smaller fan to push the same amount of air. Size of fans: At the same RPMs, a bigger fan can push more air than a smaller fan.
So, more case fans generally means you're able to run each fan at a lower speed, reducing noise.
as temperatures rise, so do fan speeds - and therefore, so does fan noise. Fan speed is usually set based on temperature sensor readings, i.e.

Here's the thing: the primary generator of noise in a case is the fans, and as a rule thumb, the faster a fan spins, the louder it will be. Instead, I want to talk a bit about the principles behind "quiet cases", because the premise of your question is actually kind of faulty: a case that delivers good thermals generally is a case that is quiet. I'm sure others will give you plenty of good recommendations for specific cases.
