Neon Light Kits and Computer Interference? 11
LightForce3 asks: "I've noticed that neon light kits are available for installation inside PC cases. Apparently, these lights are used in conjunction with window kits to create a viewable funky-looking effect inside one's computer. However, I am worried that these neon lights could be detrimental to PC performance because of the EMI and RFI (Electro-Magnetic Interference, and Radio Frequency Interference, respectively) that devices such as these often create. In other words, you could be sticking a device inside your PC case that could interfere with all the electrical signals and devices, much as how running a blender or other appliance can interfere with radio and television reception.
Is this sort of situation possible? Could those of us who use these lights be degrading the performance of our computers? Or am I completely wrong?"

This sounds like an incredibly bad idea to me. Do you know what light in the UV specturm does to exposed ICs? Just hope that the little stickers over the glass windows that your BIOS ROM might have actually do block all the light!

I have two 10" blacklight neon's inside my case.. one on the bottom, and one just under the stability bar, which puts it quite close to the processor.
I've ran stability tests and benchmark utilities with the lights on and off.. and there is no change either way.
They do create a little bit of heat, but it does not radiate much from the ends of the lights like an incandescant would
As for 'made for pc' I just used the ones from the local autozone (which are the same the pcmod places sell for much more) so it is my belief it doesn't create any harmful disturbance to the machine itself.

Apparently so since it's been running fine for 6 months now :)

I wouldn't consider a neon light to be a great source of rf. Even more so, I believe the ones he is refering to were designed to be inside cases. (ie, run from the 12v lead). (again, the power supply would be have to be designed badly)
Producing RF doesn't necessarily mean its going to interfere with your equipment in the first place. There are many many bands... aka frequencies in the spectrum.
In any event, this is a really idiotic topic and I am of an even greater idiocracy posting. Yes, I am a moron, please moderate me up (kidding, don't waste your points )

I'm not sure this is the case. My understanding is that a case manufacturer is only required to ensure that the case, as sold, meets the requirements. If they sell an empty case, they do not have to meet any EMI/RFI requirements. If they sell a case with power supply, they just have to ensure that the case keeps the power supply's EMI/RFI to an acceptable level. Compare the amount of trouble computer manufacturers go to with shielding with the amount of shielding present in most (especially inexpensive) cases sold.
RF (Score:1)
RF is only a problem for devices which are sensitive to it (tv's, monitors and radios being three examples)
The simple answer is, if you have anything in your PC which is sensitive to RF (for example a WinTV card for watching TV) then you may experience a degraded signal. Otherwise, no. You won't, it's fine.
