Fan doesn't slow down after playing games

[HunterSteele]

Whenever I play GTA IV on my computer the fan goes up to full speed and usually slows down as soon as I exit. But lately after I finish playing the fan stays on full until I reboot the computer. It makes a lot of noise, so does anyone know what the problem might be?

Have you tried maybe cleaning the fan? I'm no computer expert, but my laptop ran into a similar problem after playing Rome Total War, and I had my fan cleaned and it worked like brand new.

I'll try that. Thanks :)

Generally, fans will ramp up the RPMs when the CPU reaches a certain threshold... or the chipset/motherboard is getting hot (if, it is a PWM fan).

Since it is a laptop, it probably only has 1 fan, an exhaust to blow hot air out. Fairly normal for laptops to be loud, as it is a small, small fan and it needs to flush out as much hot air as possible.

I'd check the temps using Core Temp,

Post back your idle temp (letting computer sit after restart for about 10 mins and log the cpu temp)
and your load temp. (when gaming, log the cpu temp)

Cleaning it out is a good idea as well. If that does not work, your cpu sensor could be broken or something lol.

Something must be trapped in the fan, my laptop fan needs cleaning every 3 months as it gets clogged up, and if it doesn't it can shut down without controlling it as the fan gets so warm it needs to shut down to cool down. I suggest cleaning it and seeing how it is then, I clean mine with a can of air which you buy from computer stores or even the supermarket :)

Thanks for the reply. I actually have a desktop. I haven't cleaned it yet since it's a hassle to pull it out and open it, but I will do so soon. I have a can of air duster I'll use.

You can, if all else fails, manually adjust the fan speeds. I wouldn't recommend it, though, as you could damage or even completely break your computer in doing so.
There are programs available on the internet to do this. However, they might not always work, and for good reason, too. If a program could just go in and turn off your fan and keep it that way, that program could, in theory, destroy a lot of laptops that way. Even Microsoft has seen why this would be a bad idea.

I just cleaned my computer today. I used a can of air duster and blew huge chunks of dust out of the fans and heat sink. Sure enough, it's all quiet now. Thanks for the replies everyone :)

Take the disc out

Take the disc out
Wait, what?

Fan ≠ disk drive

It'll keep going until your computer is nice N cool, and if it is really annoying try and swap it for a quieter one.

Haha, THIS is what you could look like.
Mine would run at 5500 RPM (sounds like WAAAAAAAAAP) lol
Anyways, This is what I found after ripping her apart and cleaning her out.

My PSU's fan only activates if my CPU goes over a 60% load or a certain tempature my Graphics card fans slow down when not under load too. all my case fans are controlled by a fan controller

Previously, it would slow down immediately after I exited the application. There's no need to swap it now, cleaning the dust out of the computer solved the problem.

That's almost what it looked like when I cleaned it out.

That is not a good thing! lol, Try and clean your PC at least once a month, it'll keep it nice longer.

Don't make it sound like I'm doing something wrong now. Even though the dust doesn't benefit the computer, it doesn't harm it either. Cleaning it once a month isn't necessary since the dust doesn't build up that fast. And cleaning the computer more often won't keep it "nice" longer, since the dust will still accumulate at the same rate.

It is a true fact, keep your pc clean. Carpet is a bad place for it. Including your bed if its a laptop.

My pc is a on the floor, however I have that fake crap. No carpet. Though I have animals and I seem to track in alot of dirt and hair in, so I bought a case that has filters. HOWEVER, my cpu gets too hot when gaming or rendering so I have to leave the side panel open. Also the tard-cake who put it together put all the fans facing in, so really no airflow. Plus I am too lazy to fix that. haha, so, the case gets left open and I keep the office as cool as I can. So like in the winter, around 40 degrees. The summer, 60 if I can. Even lower at night (around 40) so it's like a freezer somtimes. LMAO

Airflow is your best friend. The more the better, Keeping it closed up without proper airflow is a bad thing. Like a GFX card that has fan(s) that spin at 100% all the time, believe it or not, it actually has an oposite effect on the CPU. It will blow hot air around the case, then the CPU will blow that hot air on itself.

If it's a laptop it can go on for a long time as it can get very hot, and the fans aren't very good.
It happens a lot with mine, but it improved 200% when I removed it, and cleaned it out. My laptop used to completely overheat until I cleaned it.
