Clean Dust out etc

Hi, do I need to clean out the dust inside the case as my room gathers a lot of dust and I often dust out my pc with dust spray? Are there any physical maintenance people do on case or disks? I have done the software tests all ok. Thanks

dust only really effects fans ie. moving parts making the noisy.

dust won’t get into the hard drives because they are vacuum sealed.

personally speaking, unless a fan is noisy i don’t bother with dusting ever (the dust will return quickly anyways, because it’s attracted to electricity)

Ok thank you very much for your help :slight_smile:
