Multiple CPU Whine Questions; Anyone experienced in this field?

If you aren't familiar with the high pitched CPU whine common since dual core processors, the fix isn't a simple forum solution such as turning on and off bluetooth or using a clocking device, so if you use google and come up with that, then that was a small battle in the epic war that is user vs. CPU whine.

I need a veteran to help me actually,

Has anyone who has had the CPU whine successfully replaced their notebook with the same processor or bought a new computer with the same specs and actually NOT gotten the cpu whine?

My question roots from wanting to know if a replacement model can in fact fix or prevent the whine, because it is a possibility that ALL of the similar models have the whine but some people are unable to hear it/report it. It is also a possibility that only some processors have the whine, or that all processors have it but the catalysts that cause it are different intensities.

If you're wondering, my brand new Envy 14 has the whine during minor cpu usage. If it was at boot up, fine. If it was while entirely idle, that would be fine too, but a majority of my computer usage is minor such as a browser and a word document, so my cpu would be emitting that stupid high pitch noise pretty much constantly.

 

It's not the CPU that whines... listen closely to the capacitors and/or inductors around the CPU on the motherboard. Add superglue around those that whine (or all of them if you can't detect which ones are making noise).

 

I shall explain my experience I had with my Inspiron 1720.

The CPU whine phenomenon predates back to Santa Rosa models, running the T8xxx and T9xxx (Even possibly the X9000) 800Mhz penryn processors. The known issue is apparent in many other notebooks in Asus, Acer and notably known in various Dell XPS and Inspiron Santa Rosa models; it's reported that some do have the issue, while others' don't (Or maybe their hearing sensitivity, I don't know) and there are known reported issues that even a motherboard replacement didn't helped either. (To answer your question, though not all successful users apply to that)

It could the that the CPU "emits" the sound, or a capacitor that does this, but however there is no concrete evidence that supports this claim. Even I don't have a clear clue what part of the motherboard or component caused a whine to happen.

The theory involves that the processor goes in C4 state while idling and that -may- caused the high pitched whine to be heard. The whine disappears when it's on full load or under 100% CPU usage; maximum stress level. At least this is what I have researched in other Core 2 machines and even my own Inspiron does that.

While some may consider the fix to be an unorthodox method and possibly not the "permanent" or "right" solution to the problem, but I have used RMclock to successfully removed the whine completely by disabling C4 state in Advanced CPU settings and it worked successfully without a sound in my 1720. (Tested in a sound proof room)

I have tested this with many users; I must warn you though, the results vary. It worked for some, but it didn't successfully worked for all; while the sound completely vanished, from my tests known freezing issues and crashes begun when the processor goes into max load and the issue is apparent in the Dell XPS models, but not in the Inspiron and Vostro models. Some Acers were "cured" and received no problems or freezing issues with the C4 state unticked in RMclock.

If you are willing to test, and, if you may, I can supply you the screenshots to configure your RMclock settings. I cannot guarantee that this may solve the whining issue; or least a crash. Or at least a motherboard replacement done repeatedly until proven successful without a sound.

EDIT: I never said this in the forums before, but I had 2 motherboard replacements for my 1720 because of the whine, but it didn't fix the problem.
