I never actually knew how pressing built-in fans are for computers of all sizes. The motherboard and CPU tend to easily warm up whenever they’re being used. Going separate from proper ventilation could truly result in an early death for an otherwise healthy PC. That’s what canned air is essentially sold for, but I appreciate using a brush on a small handheld vacuum to get the dust out of my PC system. I do this several times a year. For some crazy reason, our property has a lot more dust floating through the air than any other property I have stayed in. People tell me it’s a combination of several major factors. On the one hand, the environment here is completely rural and we have a huge amount of dust, dirt, and tree pollen swirling through our outdoor air at any given time. It tends to get into the beach property through open windows and doors, although we tend to keep windows closed nowadays for this precise reason. The other factor in our dust here is lint from the laundry we do each and every week. Clothing slowly breaks down as it is washed over and over. Most of this lint is caught by your laundry’s lint trap, however a little manages to get into your indoor air. It can collect on surfaces throughout before finding its way into your computer system sort of like how it did with mine. I have a little marijuana grow box that I bought off the internet recently, and I have to be extremely careful with the ventilation. It has fans blowing air outward to prevent anything from actually leaking in. Mold spores are able to infect your crop of cannabis plants if it is totally left unchecked. I also don’t want all of the dust from our beach property getting into my actual cannabis grow box.
