While these are general rules, they are not fixed in stone. Pretty sure I mentioned I hate fan noise. And the faster fans spin, the more noise they make. This is because 120mm fans typically have to spin faster to move the same amount of air as 140mm fans. If your case supports 140mm fan, I recommend you replace your 120s with them. Top fans are exhaust however if the top fans are used with radiators, the are often intakes. If using bottom fans, they typically are intake. This is because PSU fans are already blowing out the back. Typically you go for front intake and rear exhaust. Did I mention I can't stand fan noise?Ĭlick to expand.12cm (120mm) fans need to follow the same intake/exhaust rules to create a slight over pressure as larger (140mm or larger fans). All else being equal, more fans means more fan noise. And we are not entitled to our own set of facts. But my comments about noise, friction, heat, and power consumption are based on facts. Now for sure, my comments about fancy lighting is purely based on my own biased opinions and we are all entitled to our own in that regards. Once the newness and novelty wears off, a case is just a case with an important practical job to do. And the function of a case is to protect and cool the innards and then to sit discreetly and discretely off to the side and not become a distraction. I do understand the desire of some to have fancy and flash cases. Do you sit and gaze in wonder at your case all day, or do you tend to pay attention to what's happening on your monitor(s)? Yes, having 8 RGB fans in front all lit up with pretty lights looks neat and fancy, but does fancy lighting improve gaming performance? Nope. That could cause the PSU's fan to ramp up in speed and create even more fan noise. And of course, fans require power to turn so the more fans you have, the more your PSU has to work and thus, the more heat the PSU generates too. If that setup could not keep the components within comfortably within their normal operating temperature range, then I would slowly add more fans until they do - keeping that slight positive pressure.ĭo remember, even the best bearings and lubricant in the best fan motors are still subject to friction and thus do generate some heat. I would start with that and then monitor my temps. That is, a CPU running at 25☌ vs 50☌ gives you nothing but bragging rights.Īccording to the specs of that case, it supports 3 x 140mm case fans configured to pull in just a little more in front than exhausting out the back to create a very small bit of positive or over pressure. As long as you do that, adding more fans does NOT improve performance, does NOT improve system stability, and does NOT increase the lifespan of the components. You absolutely want to ensure adequate cooling with a nice flow of cool air flowing through the case. Multiply that by 12 and you have a little jet engine "droning" and drowning out your desired music or video/movie/game soundtracks. And metal "cavernous" boxes are great at taking those noises and vibrations and reverberating and amplifying that noise throughout the box to make the noise even more pronounced. And even the smoothest bearings in the best motors create some vibration and bearing noise. Even the quietest fans from the best makers make noise. Just because your system supports 12 fans, that does not mean it needs 12 fans or that you should use 12 fans.
