Corsair psu shroud Pc#
Most modern PC cases will come with dust filters for the bottom intakes, so you won’t have to worry too much about the intake fan pulling dust into your PSU. So if you don’t have any pressing need to orient the fan upwards, you might as well have the PSU fan facing donward to draw cool air in through the bottom of the case and keep your PSU cool. While that isn’t a lot, especially not for a PSU, we believe it’s always optimal to keep temps as low as possible for component longevity. You’ll be lucky to see more than a five-degree Celsius difference between the two. Of course, as we’ve shown earlier, the difference between fan-up and fan-down orientations isn’t huge. If your case has these, you should take advantage of them and orient your fan downwards for optimal temperatures. Why Point the PSU Fan Down?Īlmost all modern PC cases will have ventilation holes in the bottom of the case, explicitly designed to let your PSU draw in cool air from outside. But let’s look a bit more at both orientations, discussing why you may want to go with one or the other. Overall, your PSU’s fan direction won’t change too much as far as temperatures go, especially not for your main heat-generating components like the CPU and graphics card. Thirty-nine degrees, for example, is still well within the safe zone for even a lower-quality budget PSU, so there isn’t much to worry about here. But the differences are small enough that we’re confident you’ll be fine either way. Having the fan pointed downward and working as an intake fan drops PSU temps noticeably, so it’s the orientation we recommend. While some PC builders advocate having the PSU fan facing up so it functions as an exhaust fan to “suck hot air from the inside of the case,” real-world testing doesn’t bear this idea out. In this situation-a case without a PSU shroud and a standard blower-style GPU cooler-the power supply fan direction doesn’t matter. However, other components ran at the same temperatures regardless of whether the PSU drew air from in or outside the case. Pointing the fan downwards (in other words, allowing the PSU to draw in cool air from outside) dropped temperatures four degrees down to 35 degrees Celsius vs. Linus Tech Tips tested both orientations and found the only noticeable difference was in PSU temperature. Generally speaking, PSU fan direction doesn’t matter, although a fan-down (i.e., drawing air from outside) orientation is optimal.
The PSU is a heat-generating component like your CPU and GPU, but does it matter whether you orient your PSU fan up or down? Well, that’s what we’re here to find out.
However, many of us tend to forget the power supply unit (or PSU). Keeping heat-generating components cool is one of the core tenets of PC airflow. However, having the fan facing downward is optimal as it reduces PSU temperatures slightly. Your internal components will run at similar temperatures no matter where you point your power supply unit’s fan.
