I hope you were able to correct or fix this really annoying issue with the screeching sound or humming from the Air 540 case as I was and remember there is no need to return what is a solid case for a simple imperfection, A replacement will not fix the issue so save yourself some time and start getting creative right now. Installed back the screws and wallah.Ī more effective approach would be to reinstall your top fans with rubber gromets to absorb the vibrations from the fans, if you can’t find any the idea would be to get some padding material and lay it out at the contact points for the top grill to give it some padding around its edges so that it can’t vibrate thus dampening the effects of the vibrating fans. After this I closed down the top grill which gave a similar effect to pressing down on the top which significantly reduced vibration and estimated the screeching sound.įor effect I got some scotch tape and pasted the cardboard together when it was the right thickness installed it and closed the top grill down until it sat flush. Next roll the strip into 3-4 cubed pies and then place the cardboard beneath the grill on top of the fan which worked due to my airflow setup as the back side of the fan was pointing up. I simply got a piece of cardboard and cut it into a strip from some Amazon boxes, thank you Amazon I am always finding crafty uses for your many boxes that I have.Ĥ. Applying pressure to the grill in the area of the fan would cancel the noise out as the grill was not able to vibrate.ģ. I notice that when the fan was running a lot of vibration was being produced and was being amplified by the case and Upper grill. I removed the Corsair Air 540 case top grill which is easy by removing the rear screws and sliding the top off.Ģ.

Remember that all setups are a little different and that while my fix may work for some the exact same way others will have to mod this easy principle a bit to have it work for them:ġ. In my case I installed a Corsair H55 which was enough to really get the grill rattling especially when the CPU would throttle up the fan for extra cooling. The annoying sound that is being produced in all cases is caused by the upper Fan Grill that can be removed with the two rear screws and be slid off easily, what happens is that as soon as you mount a fan beneath the upper fan grill the vibrations are transferred to the grill which produces a annoying high pitch sound that just too high. He has added an extra level of annoyance by putting the noise in vicinity of 17KHz thus making it. Now you might be thinking of returning the case for a replacement and that’s crazy when it can be easily fixed with a little creative modding that anyone can do. It randomly emits high pitched sounds, then stops for a while to make it very hard to locate. Well for one the issue is that while the Air 54o is a solid case which I love, it however tends to develop a very annoying high pitch sound that enough to drive anyone crazy who has had it develop in their build.
