I hear my computer processing...

Yes it's true.

When it's quiet in the room, I can hear the laptop make a strange noise, kind of like when you pickup the phone but there is a modem online.

WHen the CPU is idling, the noise is there. But once I am running something intensive, noise goes away.

It's not really bothering me but very curious to know what that is. An older ACER laptop did this too, so must be normal.

However, when I clock down using CPUID, the noise disappears once I am at only 1 GHz.

What do you think it is?

 

I'd say it is your fans. I also had a laptop that did the exact same thing you are saying. The reason the noise disappeared at 1GHz is most likely because the fans spooled up to a higher speed in order to compensate for the extra heat output from the CPU.

 

It's definitely not the fans.

It sounds like static inside the case, but if I pay attention, there is a definite pattern to the static sound. There is a quick "shhhh" "silence" "shhhhh" silence"..in other words there are small pauses in between the sounds. This is happening at idle (without using any declockers)

If there is silence around you, give it a try and see if you can hear it ..

 

You're correct - it is electricity moving over the CPU/GPU. Just looked it up. That is nothing out of the ordinary, no need to worry.

 

Very cool. I wasn't worried since I've heard it on other laptops, but mine just started making this noise lately. Maybe it needed to break in. Thanks ;0)

 

BTW, where did you look it up, I'm very curious to read up on that. Thanks

 

You may find this funny, but I found it on the Intel site - referring to the 386 processor.

"Low-voltage designs are less noisy. Noise is related to both the voltage swing and the transition time of transistors switching in a device. Because low-voltage devices have decreased voltage swings, they generate less noise. Decreased noise generation is a substantial benefit to applications that are required to comply with noise emission regulations. Low-voltage designs can avoid potentially expensive noise reduction techniques."

It's simple - when the processor spools up, it uses more voltage, and therefore, that's where you get the noise from.
