Used to be that HSF's were (perhaps some still are) high power draw items and it was unwise to connect them to the motherboard fan header but instead to a power lead from the PS. For example, Delta fans were notorious for needing more power than the motherboard header could supply. OK, now many PC cases come with 120 mm exhaust or even intake fans; some are gentle giants while others are vacuum cleaners. What's a good guideline to follow for when it is okay to connect these 120's to the motherboard header vs. hooking directly to a power supply lead?

Agree with don't plug them into the motherboard, unnecessarily drawing power through your board.
