hints or tips for HL opposing force

[Tripleshot]

I am stuck in some room with fans twirling that vibrate when you traverse thier framework and I can't find a solution. Is there a site for hints?

You've got to walk on those supports. In the end, there's a ventilation fan w/only one fan blade spinning. Drop into that vent.

Thanks for the tip,but every time I try to drop into that open hole,I get my head chopped off. Are you supposed to disable the power somehow or can you blow up the last remaining blade that keeps chopping me to pieces?

Timing...

Drop in immediately after the blade passes. Don't lollygag for positioning.
