About 2 days ago i opened PC case to do my regular maintenance of dusting inside. Usually use Compressed air.
Have 2 case fans (1) 92mm (1) 80mm plus the CPU Cooler fan, my Graphics card has dual fans.
Just other day and this only happens when i am booting the PC, i hear what sounds like and what i can only describe as a horn sound as the fans speed up at boot , then it goes away as fans slow when i reach the sign on page. After i do not hear any noises from them at all.
As usual i know my graphics card fan speeds up when i boot the PC this is normal i know. This issue does not happen every time, it's occasional since day i dusted it out. Weird part is when i opened it to inspect the possible cause i reboot number of times and nothing happens with case open, thinking possible vibration. When i put case cover back on did not do it after a couple of attempts, but eventually did, not every time though.
Wondering if a case fan, PSU fan, or Graphics card is going because it's not every time, like 1 or 2 out of 10 times i reboot to try it. With cover off it never happened, could it be air flow difference with cover off, a possible vibration but i can not figure it out if i do not remove cover then.
Kind of stumped, don't see anything possibly loose or could be hitting something inside case.
Also tried stressing the Graphics card with program called Valley Benchmark to see if card whined, but it handled this good.
Not sure what else to think, unless compressed air caused some kind of issues.
