What power option plan is best to minimize fan noise?

Hello:
Sony Vaio Desktop VGC-JS320J

E5400 dual core processor

The fans on my desktop are loud and running at a high RPM for seemingly no reason.

Here is the history of the problem.

Initially, when I booted the computer, the fan RPMs were at about 2200 RPM. After about 3 hours the RPM were at 3,800 but the temperature of the cores remain at 36 and 38.

I don't do anything that taxes the processor. I just surf the internet, use Microsoft Word. When I run adobe flash player to listen to a radio station, that does seem to cause the fan to run faster. CPU usage is at 10%.

I sent my computer back to Sony. They replaced the fan. The problem has become worse.

Now within an hour the RPMs are up to about 3,800.



I am using HWMonitor to obtain the fan readings.

I have been advised to set the Windows 7 power option to each of the plans (balanced, high performance, and power saver) to alleviate the problem. Obviously, only one person is correct.

When I set the plan to "High Performance", the fan does not seem to run as high, but I am still not sure this is the optimal setting. It is counterintuitive. I would think that by having the setting at "Power Saver", the fan would be quieter. The core temperature seems to rise to the mid 40's at the "High Performance" setting which I don't mind because it is still not too high.

What about the advanced settings for the power plans? What are the optimal settings? Especially the Multimedia Settings/"When playing video". Would the fan run slower with "Optimize Power savings" or "Optimize Video quality".

I know this is a Windows forum, but someone suggested changing the settings of Smart Fan in the BIOS. Does anyone know how to do this? When i go into the BIOS there are no options to change any fan settings. It just has a setting for the two fans. They are both at around 2,200.

Are there any settings in Windows that would allow the temperature of the cores to rise a small amount without having the RPM of the fans increase?

Well lets see if we can fix the problem instead of a work around. How old is the computer? Has its fan and heat sinks ever been cleaned? If the computer is over 6 months old has the heat sink thermal paste been reapplied?

Power saver will use the least power and hence generate the least heat.

The computer is one year old. When I took the computer to Sony, everything inside the computer has been cleaned.

Nothing we do on the computer stresses the processor.

I just surf the internet, use Microsoft Word, and play Ma Jong.


The temperature of the cores remains at 36 and 38 degrees. Why do the fans have to increase speed?

Does internet explorer put strain on the processor? What about Microsoft Word?

Or is it just the CPU fan? You could use Speed Fan to control your fans if indeed they aren't being sped up due to a failure or overheating issue. A Guy

There is a front fan and a cpu fan.

The front fan is always 300 RPM higher.

I tried to use Speed Fan, but the fans don't show up on the program. The fan tab is blank. My computer might not be compatable with it. Are there any other fan control programs?

My fans usually are at around 3500 and 3800 RPM. Should they be noisy at that rpm?

Use Speccy and fully complete your system specs. That info will help us in this and further questions.

The Power Saver setting will result in the coolest operating temperatures.

Take the cover off of the unit.

Listen and observe the various fans after starting up and then later when the fan speed increases significantly.

I'm also suspect dust bunnies of being the biggest part of your problem, although you could simply have a fan that is malfunctioning.

I did send the computer back to Sony and they replaced the fan and cleaned out the inside of the computer.
