Pc Fan Loud on Startup Reddit

If you’re a PC gamer, you know that one of the most important things to keep an eye on is your graphics card’s temperature. If it gets too hot, it can start to throttle itself and cause performance issues. One way to help keep your graphics card cool is to make sure your PC’s fan is running properly.

Unfortunately, some users have been reporting that their fan is incredibly loud on startup, making it difficult to enjoy gaming or even use their PC for basic tasks. There are a few potential causes for this problem. It could be a simple software issue that can be fixed with a driver update.

Or, there could be something wrong with the fan itself. In either case, it’s important to figure out what’s causing the problem so you can get back to enjoying your PC. Here are a few things you can try if your PC’s fan is loudly on startup:

Update your drivers: If you haven’t updated your drivers in awhile, that could be the cause of the problem. Head to your manufacturer’s website and download the latest drivers for your graphics card and other hardware components. Then install them and see if that fixes the issue.

Clean out your computer: Over time, dust can build up inside your computer and impede airflow. This can lead to overheating problems like the one you’re experiencing now. To clean out your computer, shut it down and unplug all of the cables.

Then open up the case and use compressed air to blow out all of the dust from inside.

Why are My Pc Fans So Loud on Startup?

One of the most common questions we get here at PC Fans Plus is “Why are my PC fans so loud on startup?”. There can be a number of reasons for this, but in this blog post we’ll go over some of the most common ones. One reason your PC’s fans may be louder than normal on startup is because they’re trying to compensate for a lack of airflow.

If your case isn’t well-ventilated, or if you have a lot of dust build-up inside it, then your fans will have to work harder to move air around and keep everything cool. This can lead to increased noise levels. Another possibility is that one or more of your fans may be failing.

If a fan starts making strange noises or doesn’t seem to be spinning as fast as it should be, then it’s likely that it’s on its way out. This can cause your other fans to work overtime to try and make up for the failed one, leading to increased noise levels. If you’ve ruled out these two possibilities and your PC’s fans are still noisy on startup, then it’s likely that something is wrong with your computer’s BIOS settings.

In particular, there’s a setting called “Fan Start Temperature” which controls how high the temperature has to be before the fan starts spinning faster. If this setting is too low, then your fan will spin faster than necessary and produce more noise than necessary. else{}

How Do I Stop My Computer Fan from Being So Loud?

If that doesn’t work, you may need to replace the fan.
