ECN Forum Forums Technical Discussion Re: Computers and the Internet Noisy Computer?.

I bow to superior knowledge . Yep, the bus being the source would make sense, it's more exposed. I think case design has some bearing as well as motherboard design though, especially with today's very high speeds. One of the nastiest causes of interference I have found is bad grounding. In fact, the level of TV interference from one of my PCs alerted me to the fact that the PSU input connector's ground pin had a bad solder joint
Measuring 120v ac on the case of the PC was scary.
(I traced that to being half mains voltage of 240v from the relatively high leakage filter)

Again, that is a filter to keep the switcher noise out of the power grid, not to protect the computer.

How do you work that out?

Something they told me at IBM.

Mike, you can always buy more expensive coolers on the electricity box-side or for the cpu, made of copper.
