There is a chancethat there’s something wrong with the fan. And if that’s the case, it can causeserious problems down the road.
What’sWrong With the Fan?
Computer fans arethere to provide cooling. The harder your computer works, the more heat itgenerates. That’s why fans are strategically placed on your computer. They helpregulate the internal temperature so that your PC continues working withoutoverheating.
Fans can work foryears without issue. But there comes a time when it breaks down. Regularwear-and-tear cause fans to degrade over time. Or it’s triggered by improper maintenance.
That said, youshould clean them regularly so fans remain in tip-top condition.
Dusting off yourfans will get rid of the loud whirring. Do note, however, that it’s normal forfan noise to occur especially when under stress.
Howto Clean Computer Fans
Cleaning fans isnot as hard as you might think. It also doesn’t take a lot of tools. In mostcases, all you’ll need is a rag and a can of compressed air.
So if opening acomputer case is giving you pause, rest assured that there’s no need to worry.
First, turn offyour computer and unplug it from the outlet. Unhook all the plugged cables.
You will beblowing off dust so consider moving your PC to an open space.
Open the case byremoving one or both panels using a screwdriver. If you have a tool-free case,unlatch the hinges to open the panel.
Once exposed,clean the case fans by blowing compressed air into every nook and cranny.
While you’re atit, give the motherboard, graphics cards, hard drive, power supply fan, and othercomponents some attention.
Be careful not tomess up your PC’s wiring.
Clean and openlaptops the same way. Use compressed air to remove dust from the fans and theheatsink.
Something to keepin mind. There are manufacturers who void the warranty when users tinker withthe inside components. Contact your manufacturer’s tech support if you’reunsure how to proceed.
Once you’refinished, re-attach the panel and plug everything back in. Open your desktop orlaptop to check if there’s still a loud whirring noise.
If your fans areclean but the fan noise isn’t dropping, then the issue could stem from runningtoo many tasks.
In simple terms,the fans are compensating for the heat generated by the CPU.
Some programs aretoo draining to run on top of other programs. Try turning off applications whennot in use. You can also try running apps one at a time.
There are timeswhen your operating system will run background processes without yourknowledge. It doesn’t matter if you’re running Windows 7 or Windows 10.
Fortunately,there is a way to find out which tasks are overworking your CPU. You can use Task Manager to find your culprit.
Open Task Managerby pressing CTRL + Shift + Esc. If the window opens in SimpleView, expand by clicking MoreDetails.
Go to the Processes Tab. Observe the numbersunder the CPU usage column. Arrangethe column to display which programs are consuming the most memory on top.
The CPUpercentage should be nowhere near 100% when in use. Should you find a programthat’s running near that, you can force it to stop working.
Right-click thename of the application. Click End Taskto stop the program from working.
There are Windowsapplications that will stop the computer from working when ended. You will beshown a warning if you try to stop a vital process.
