Small vibration threat to PC?

[Guest]

So my new build is very noisy but that's not a concern to me given I did select high RPM fans while on a budget. However, the case does have a small constant vibration and if I use a high-backed cheap mouse I can feel a tiny amount through that as well. However the vibration really is not there much on the desk itself and is also not visible at all. I can't hear the vibration, I can't see the vibration even when I look inside, but I can feel it when I touch the side of the case or the area around the hard drive mount. I'm not entirely sure what is causing it, but I know my case fans mustn't be because they are installed extremely tight and when I touch the case fan chassis they are not vibrating at all really. My hard drive is also very well secured but the vibration does seem to be worst around that area somehow, it's a brand new WD blue 1tb 7200rpm hard drive and very tightly secured too. The only remaining culprit I see is my Deepcool 92mm Alta 9 CPU cooler which due to having a 3 pin connector runs its fan constantly at 2100 RPM. The fan body itself does seem to be vibrating but the push pins to the motherboard are all secure and the white parts of the pegs sit about level with the black parts of the pegs on the other side of the mobo. So, I know vibration can kill hard drives but TBH a hard drive isn't the worst that can fail on me and it will be no more than a sizeable inconvenience to me if it were to break, not to mention I can move it to a different part of the case etc. But should the rest of the components be fine over a few years or so? They're all screwed in tightly and secure and are not visibly vibrating. Also- my case is a silverstone PS08B

Vibration CAN cause issues, but HDDs are designed to counter it, so there's no real worry.
Plenty of cases will vibrate, especially less expensive ones with thin metal construction and sometimes two or more fans will combine their vibrations, effectively using the case as a sound box, like the body of a guitar, to amplify the noise.
Suggestion: Turn each fan off in turn and see if that kills the noise, or run the fans at slightly different speeds so their vibrations cancel each other out.
A constant hum is usually caused by the HDD, though, sometimes moving it to the top or bottom position helps.

Thanks for your solution. I don't care much about the noise but unfortunately your suggestion of running the fans at different speeds won't work as my ASRock H81m-HDS motherboard only has one variable speed port available and that is blocked by my GTX 950. So, I can't adjust fan speeds as the exhaust is linked to PWR_FAN1 and front 120mm is linked to molex
