I have a Sony Vaio VGN-S360 with an irritatingly loud fan. Everywhere I've looked online it seems it is common or typical for Vaio's to have loud fans. I've tried suggestions I've found online, with no success. I believe mine is beyond "loud", though, and on the verge of "what the hell is wrong with that laptop?". The closest I can come to explain it is a grinding. I have seen other VAIO users report that theirs comes and goes with the temperature of the laptop, usually after prolonged use. This is non-stop, from power up to shutting it down. It doesn't increase as the laptop gets warmer. I actually don't even see any change from the time I turn it on until the time I turn it off - it's a constant noise at the same volume. It's almost as if the fan can only do the highest setting possible, like it's stuck in that one setting... not sure if that's possible, but that's the best I can do to explain it. I love my laptop, old as it might be, but the noise is starting to get very irritating.
Things I've tried (not necessarily in order):
- Undervolting - I read a lot of topics of undervolting the computer, which I tried, but it didn't seem to quiet the fan. I don't know if I was doing it wrong, or if it just wasn't a good solution for my problem.
- Cleaning - I disassembled my laptop completely and meticulously cleaned every speck of dust I could find, using mainly a can of compressed air, and Q-Tips where necessary. At first I was quite excited, since I found a lot of crap gunked up in the fan itself, I thought it MUST be the cause. Until I put my laptop back together to find it didn't make much of a difference in sound. Although it doesn't seem to get AS hot. The laptop gets quite hot to the touch after 10-15 minutes of use, so hot that touching the keyboard becomes a nuisance. I could put it on a table, or balance it on my two knees so it had as much circulation underneath it as possible, and it would still get so hot I couldn't even keep it balanced on my knees. So, I bought a laptop cooling pad that works quite well and I no longer have that problem. It keeps the computer very cool - the vent on the side still blows rather warm air, but everywhere else stays perfectly cool. The vent on the side went from quite warm to slightly warm after cleaning it, though. It was an improvement, but not in sound.
- Changing power management settings - Control Panel / Power Options / VAIO Power Management - I can change the settings to optimize battery life or optimize performance, or choose somewhere in the middle. Even when I switch everything to optimize battery life (CPU Control - Adaptive - CPU Fan Control - Level 1 [quiet]), it is still loud. It does quiet it down, though. It goes from so loud that I get tempted to pound on the laptop in hopes it will shut up, to just loud. However this also takes away from performance. I can't play games, watch videos, or listen to music. Webpages also load slower. Since this works, even slightly, it's more of a temporary solution. I would like a much more permanent solution.
Does anyone have an experience similar? And possibly a solution outside of what I've already tried that worked well that you're willing to suggest? I have considered replacing the fan, it seems that may be my last option. I am comfortable doing so. My only problem with that option is with the age of the computer, I wouldn't really know where to find the proper replacement part for it. I also don't know specifically how to replace the fan. I was able to completely take apart my laptop successfully and put it back together with no problems, but I am a little concerned with replacing parts, as I've never done that before I would just like to make sure I don't screw anything up by touching the wrong part, or something.
*edit* If it matters, I forgot to mention my CPU Usage shown in Task Manager is ~25%-30% as I type this, and when I am not typing or doing anything active it falls below 5%, usually 1-2%. The only time I 've seen my CPU at 100% is if something has frozen with IE, usually my fault from opening too many webpages before allowing the last to load properly. Keep in mind this is with the power settings I mentioned above set to keep it as quiet as possible.
Thank in advance! This forum is great...
