So if you live in Northern Canada and theres a solar flare, you will have to be careful to align the PC so that the magnetic fields do not cancel . the same can also be said of living under 400KV power lines. That peak power surge while the ads are on tv could cause your fan to fail if the magnetic fields are not aligned. Remember Maxwells rules for determining the position of your PC.
