You may be thinking about getting a 120mm fan guard. You need to make it a priority to get it done. This shouldn’t be considered optional because it is going to increase the risk of your electronics not working as they should. You have too much money invested in that device and too much information on it to take that type of risk! Purchasing a 120mm fan guard is very inexpensive, and you can install it on your own. Put forth the effort to find a well-made product that is designed to last. If you live in a region with high humidity, make sure the materials are corrosion proof. Select a product that secures in place without the risk of noise and vibrations that will drive you crazy. As you shop for 120mm fan guard products, you will notice significant differences among them. The prices, the materials, and even the shipping costs should influence your final decision. You want something you can buy for a great price and really count on. You don’t want a product that doesn’t hold up well and you soon have to replace it. Materials The best ones are made from durable metal. There are also those made from plastic, but they tend to not hold up as well for the long term. You want a product that fits snugly on the edges where you secure it with the screws. It shouldn’t be too large or too small and it shouldn’t move around once you put the screws in place. Look for a design you are found of too. There are many of them to pick from. Some people have a preference and others really don’t mind what they see. Since the product is going to be in place for a long time, you may as well get something you like to see. It can be fun to look at the many designs and find one you like the most. Keep Fingers Out It may surprise you how often children and even some adults will put their fingers into the area where the fan is located. This is very dangerous and it can result in serious injuries. You may have a pet at home around your computer, and their paws or tail could end up in there too, causing them injuries. You can keep all of this at bay with the 120mm fan guard in place. The openings that are left will vary, depending on which type of design you select. What they all have in common though is they don’t allow any body parts or pet parts to get in there. The openings simply aren’t large enough. This is a wonderful way to reduce problems that you didn’t foresee. Don’t wait until something happens to wish you had gotten the fan guard in place. Filtering With a 120mm fan guard, you have a filtering system in place. First, it allows air to get in there and circulate. This is a vital part of the fan being able to operate without overheating. Second, it prevents debris in your environment from getting in there and harming your fan. This happens far more often than people realize. Having the 120mm fan guard in place can be a wonderful source of preventing serious problems. Overheating is dangerous because it does cause the fan to not be able to cool the device enough. It is very expensive to pay for repairs and replacements, but there is downtime when you can’t access what you need to. Going this route, you can do your part to eliminate such concerns.
