Fans are loud at idle temp

Hi, My temp is barely 50degree on all cores but yet fans are loud. What could be the issue ?

 

Fan performance mode turned on in bios?

 

Are you using any of the overclock settings in the bios? I noticed if i turn on any of them, my fans start getting very loud even tho my temps are normal. If i disable it then its fine. I went and downloaded HW64 and went into the fan options to see what they were running at and i found out that my fans were at 3500rpm when they were supposed to be at 2-2500rpm. You can click default auto and they will go back to the correct settings, but after a minute they revved back up again. I ended up going in there last night and setting a custom profile which matches the alienware stock one. It seems to have solved my issue and keep them at the normal rpms now. I only tested it for about 2-3 hours, but so far so good. So you might want to download that program and take a look.

 

great! can you make a screenshot of your hwinfo profile?

 

I changed mine a bit from the default. Just click on the fan icon in the bottom right, and that window will appear. Then click on custom auto. The stock number will show up, and you can just hit okay and it will save. But i change my number 2 so it they dont rev up till 50c instead of 40c. The fans become audible at 3000rpm so i just set that to 60c which so far has kept it quiet browsing the web and all that. The only time its going to get over 60c for me is gaming, and i just set those in 5c increments instead of 10c. You can play around with it depending on your temps.

When your selecting the sensor at the top your going to see like 6 options. Just find the one that makes "cpu package" show up in the second drop down menu. I set the gpu fan to custom too for the hell of it but i just left that at stock settings since it never gets loud anyways.
