| 1447026 | 2018-03-06 19:25:00 | Yes talking about noisy fans. My desktop has always made sort of up and down fan noises. One minute it is fairly quiet, then there is a sort soft grinding noise, then it goes quiet again. Its never got any worse over 4 years, so I hvae not worried. But how to find out which fan it is. CPU, PSU or case? You sure you aren't talking about the noise hard drives make? Another source of noise is fan grills, if they are poorly shaped they can add a lot of extra noise. Even a normal mesh can be very loud if the fan blades are too close to it. I have run into it a few times, the worst was a side fan on a case window with laser cut slots - sounded like a vacuum cleaner. I've proved this to myself by removing the grill and comparing the noise. |

Grills are a waste of time, unless there are children around poking things in :) Mostly the holes are too small, and in any case, a wind tunnel test I made up on different grills with various holes showed the flow rate is halved or more. The best I tested had 0.6 the flow of an open window. There is the reduction in area due to the metal around the holes, and then there there is pressure drop through each hole acting as an orifice. Best to remove and have open for your own computer. |
