Is there a way to turn off my fans in my MBP?

[DoNoHarm]

Hello Everyone,

I am about to buy a new HD and I am leaning towards the seagate momentus 5400 500gb drive due to noise, power consumption, and size considerations. I was thinking that it may be interesting to see how much of the noise from my laptop comes from the hd vs. the fans on the logic board. Is there a way (or a 3rd party program) to momentarily turn off the fans on my logic board? obviously I'd do this only for a short few seconds to avoid overheating....

I don't think so and I would advise against. There is a reason that the fans constantly run and even turning them off for a bit may be dangerous

Edit: yeah SMC Fan control could do that. But I think they have safeguards in the program that have safety overrides to prevent just that.

I found a page that changes some low-level settings that may do what you want to. I can't remember where it was though...

And you're right about the safety stuff. If you dug into the code though, you could probably change that.

Unless you're interested in burning out your CPU, I'd advise against that. They're on for a reason - the temperature.
