Mine used to be really loud until I opened it all up and cleaned all the vents and fans of dustcarpet fluffgf ' s hair . Now it ' s really quiet again . Before I cleaned it , if it was running for a while and I changed games it would go into crazy fan mode and sound like it was about to take off , 30 seconds later it would go back to regular fan speed . It ' s quite easy to do , obviously only if you ' re out of warranty . If you do decide to open it , use a softer plastic then the shell to pop the clips or you will mark the case I used an old ATM card . When you ' re watching a tutorial and the guy sticks a metal screwdriver into the seam and start writhing at it , find another tutorial Another tip is , Clean the fan with a soft , damp cloth slightly damp , not even remotely wet . If you must vacuum , be very careful of static build up or just don ' t vac any of the boards etc . The top and side panel can be washed in soapy water obviously ensure all electronics are removed firstJust be very careful , don ' t apply too much force to anything and you ' ll be fine . The plastic clips that hold the case are strong , and feel like you really need to force them . You don ' t , just wiggle and apply a small amount of pressure as you continue to wiggle your opener and the clips will pop .
