Computer Fan Running on High quite a bit
« on: March 2, 2013, 12:22:58 pm »
I'm getting nervous, my computer fan keeps kicking on high, and I don't know why it is doing that...its about 2 1/2 years old, and it still works ok, but the internet is slow also...I don't know anything about computers, so the only thing I have tried to fix it so far is blow out the tower/fans with the compressed air...it didn't seem to really help...when I look at the processes, it doesn't seem to be running too high (25-50%), but it keeps doing it anyways....any ideas?  Suggestions? Things to clear or whatever?  Thanks

    If there is a filter, clean, or replace it. They are in various locations, but many are behind the front cover.

    The fan is a heat issue. either not enough ventilation, or too much heat being generated. 50% is a bit high. check what the processes are and make sure they aren't going out of control.

    I know this post is older but i'm going to give my opinion anyway. How did you ever make out with it?

    System running hot would causes the fans to run fast. Now you said you cleaned out the system with compressed air. That is a good start. But please tell me you prevented the fans from moving while you did it. Spinning the fan with compressed air will cause them to spin at an rpm above what they should and will burn them out faster. Now since you did that you were talking about processes running a bit high. You could have a virus or even spyware/malware built up on the system causing it to run too much stuff. I live by these 2 programs I am about to mention and I recommend them to everyone. Go to Microsoft site and search for Microsoft security essentials. It's free. Download it, install, update, and let it search the system. Remove anything it finds. Next download malwarebytes. A quick google search will bring up the site. Download the free copy, install, update, and scan. I have a purchased copy of malwarebytes and it protects my system real time. With both installed I never have to worry about spyware/malware or viruses. I'm not saying to go buy the software. I've been doing pc repair for 15+ years now and its the best I've found out there.

    Hope this helps with your problem if you haven't solved it already.

    Yes! I totally agree. Also, judging by the penguin, Iím guessing you are a Linux user, as well?

    My Malwarebytes really cleans stuff out. on top of that, I use Ccleaner and Spybot on my windows machines. I usually do scans once a week or so and my system runs clean. I dual boot with Linux, though, so Iím not toooooo concerned for viruses.  :D

    You might need to reapply some thermal paste. Generally after only 2 years it shouldn't be dried up but if you're gonna replace it use Arctic Silver compound. Fans don't start spinning faster for no reason. If it's grinding you may need to replace it soon but I've had some grinding fans last for years.
