Hmm, I've heard about the static electricity issue but I don't know if it is true or not, I myself had problems in one of my coolers once, had to spend several days using a fan, never had a single problem. Perhaps in your case you kept the fan way too close to the computer? In any case, I think it is up to the owner now >_>. There might be a small risk if what she says is true, but I wonder if there would be a problem if you tested it for a single hour, playing games and executing heavy stuff.
