I have a rather new gaming PC, I built it last Christmas. For a majority of its existence it has not had any problems, however one day something happened. I had played Skyrim and other things on it before, and had been for some time, and while it had been spinning up its fans and all the other things a machine does when a load of activity is placed on it, nothing unexpected had happened. Then, during a somewhat graphically intense fight, this sound occurs that I had never before heard. It is a rapidly repeating monotonic buzz that occurs not when a game, for example FEZ, starts but after some time in game.
I think it is caused by a fan because they are, besides my hard drive, the only moving parts and they spin faster and faster as length of game-play and intensity of game-play generate more and more heat in the components.
I opened by computer and found that a caseing for the GPU was lose, I tightened it up and and checked the other fans (CPU, case, couldn't get at the Power supply fan) and they seemed firmly anchored.
Reassembling the machine I tried to play FEZ and things were going ok, then the sound came again.
I got OpenHardwareMonitor and tried to set each fan in turn to its highest level to see what the result was so as to isolate the thing that caused the sound. It isn’t the GPU fan I think as I set that to 100% and could hear it going but there was no buzz. However I do not know that I was able to actually change the speeds of the other fans for while I did raise other fan “controls” to 100% I did not detect, in either the read outs or by sound, a rise in their activity.
So, any ideas? Do you think I am right about it being a fan? The computer runs and has run normally at non game levels so it seems to be triggered by some such load. It did not always happen, so what changed? Is there another piece of software you recommend that might give me definite control over the other fans so as to test them (Note: speedFan makes my computer freeze necessitating restart)? I didn't even see the power supply on the hardware list in OpenHardwareMonitor, maybe I didn't look long enough. While the inside is not very dusty I am going to give it a through air blasting. I do not think any cables are being pulled into the fans though this kind of bicycle spoke sound is not far from what I hear.
If I have unknowingly committed some breach of forum protocol please let me know or if I missed this being covered in another post despite my searches please direct me to it, thank you in advance for any assistance rendered.
