Forget the heat in the PC with the most powerful USB fans on the market

It must be clear that a fan does not lower the ambient temperature, it simply moves the air to create the sensation that it is less hot and, without a doubt, except in extreme heat conditions it is something quite effective. For its part, an air conditioner does lower the ambient temperature but it has many disadvantages, starting with its high electricity consumption and because it can cause respiratory problems. For this reason, whenever possible it is more advisable to use fans instead of turning on the air conditioning, since it is much cheaper and better for health.

The benefits of using USB fans

As we have already mentioned, using USB fans instead of air conditioning has many advantages and only one disadvantage, which is none other than the fact that it does not really lower the room temperature, but simply moves the air to create that feeling. However, and especially when we talk about USB fans, the electrical consumption is really very low and even more so if we compare it with an air conditioner, because its consumption it can be literally 100 times less.

On the other hand, air conditioners have multiple health-related disadvantages: they cause dryness and irritation in the eyes, they can cause pain (problems in the musculoskeletal system due to the cold, something that causes neck pain, low back pain, stiff neck, etc. ), affects the vasovagal systems due to sudden changes in temperature, can cause dermatitis, and of course they also generate much more noise than a fan.

Therefore, and whenever possible, it is more advisable to use fans than air conditioners, and if these fans have a USB connection they will provide us with greater comfort since they consume less, take up less space and we can also place them almost anywhere.

What to look for when you want powerful fans?

Obviously, when we want “powerful” USB fans, we need them to have a high speed of rotation but also that their blades are wide and with little angle on the horizontal, something that will encourage them to be able to move a greater flow of air to the detriment of the static pressure (for this purpose, we are not really interested in static pressure but in greater air flow).

On the other hand and since we are talking about USB fans, we want their only connection to be that, a USB connector, and therefore they do not need additional power since if we have to plug them into the power outlet, this would take away that versatility. that the USB interface inherently has. Likewise, and since we are talking about small devices (as a general rule), we are interested in having certain ergonomics so that we can direct the air flow to where we are interested, or in other words, that they are not fixed and that we can place them where we want.
