Vista fan problem

Well recently on my 1 month old Sony FW390 i have been hearing very loud fan noises. I havent really payed attention to them but im pretty sure they have been like this since i got it. What is happening is whenever im downloading like a torrent the fan gets extremely loud and stays that way until the download is done. Also when im converting a video ive noticed it does it also. Now when im just surfing the web the fan is moderate and fine. I have heard of some programs to control the fans etc. but none work with vista 64 bit. I have my laptop on a wooden desk if that matters, the laptop is basically brand new and dust is not an issue. The fan acts normal when im playing games, every about 5mins it turns on for about 3 mins at full speed which is typical. But i dont think its typical for it to be full speed the hole time when im downloading something. So what im asking is there a way i can control this? I like to leave my laptop on at night to download stuff, i have the setting on just dim display. I really want to continue to leave it on at night but it just gets so loud and its ridiculous. So basically is there a way to control this? does vista have some option to turn off all the background programs and not use as much CPU but continue to download the things being downloaded? Or do u think its a hardware problem?

Thanks

 

Well first off, Vista has nothing to do with your fan speed. Your fan speed is determined by the BIOS, depending on your current workload and temperature of your CPU / GPU. The fact that the fans are spinning up on a .torrent download points to a malways application running in your client (very typical of many p2p applications). When this is happening, your CPU starts working for the client, and the BIOS kicks the fans on. If there is no malware, perhaps you have a very fast connection and are downloading several MB/sec? That can cause quite a workload.
Video encoding maxes a CPU, causing the fan to spin up.
Games are usually not as dependant on the CPU as it is on the GPU. You likely have the Radeon HD 3650, which is a weaker card, not requiring a powerful cooling solution. If you have the 3GHz T9900 that most of this model ship with, it will be twiddling its thumbs when combined against the Radeon HD 3650.

Fan programs usually only ship with certain manufacturers, and only work with particular systems. If you want to throttle things, use Power Management, select Power Saving profile, choose advanced options, and set the minimum CPU throttle to 0%, and the maximum to 25%. You might try a different .torrent client.

 

You may also just have heat buildup problems when your hard drive runs for a long time (as it would if you're downloading for a long time, like from a torrents), or when you're doing a lot of intensive video work. As is most likely the case, the hard drive's constant activity is causing heat to build up in the system, which in turn requires that the fan run continuously at high speed to exhaust that heat.

If you want to solve it, stop doing things that put a continual load on the hard drive (like downloading from torrents). If you try to "control" this by finding some application that will allow you to shut down or slow the fan, you will end up cooking your computer in its own waste heat. The solution is to either invest in a pair of earplugs, or get a better computer.
