Question about Dell Optiplex GX280 (99301) Motherboard
Hi, I have the same computer, and the stock fan that's installed has a very high rpm. It is a variable fan that can actually be set in the bios to run in a quiet mode or in a mode that is more for heavy work, like your gaming, or other intensive work that requires a lot of processing. Other tasks that require the processor to work harder are graphics, CAD, audio recording, and video editing and viewing. You will notice on your dell, that you can actually hear the fan go through different speeds depending on how much work the processor is doing. It can get loud, and you may even think that maybe something is wrong with your fan, but that's just the fan attempting to cool the processor as it's working. This is software controlled based on the temperature reading of the processor chip. To use a quieter mode, you can enter your bios during startup, and find the fan settings. Change the fan setting to the quieter mode (it actually reads something like "quiet mode" or office mode" or something like that - very easy to determine. Then save your settings and exit bios. I need to tell you though, it's not much quieter. There are quieter fans you could buy for your CPU, but it may not be worth it to you. I had my cpu sitting on top of a side desk, and it was unreasonably loud. I plaecd it on the floor under the desk, and now I can barely hear it. Maybe you need to place your cpu further away from you in such a way. You can even get foam and "soundproof" your cpu, remembering of course, not to cover the ventilation holes in your case, or cover any part of the processor or motherboard - just the interior walls of the case. A lot of techs I know who need their processor near them (disk and rear panel access) use this technique. Hope this helps.

Well this must be due to improper placement of the machine. YOu must have placed ur machine some where where there is no any proper cooling conditions. As the processor gets heatup, the fan start getting fast.
