is there a way to manually control the fans?

ok, first of all dunno if this is in the right spot, hopefully it is...

i've noticed there are alot of temp related issues being rpeorted about the MacBook/ MB pro...

so i was wondering if there was a way to manually control the speed of the fans, i.e. turn them on/make them faster when ur computer gets hot...the way i understand it is that the fan is constantly running at what ammounts to an idle speed, obviously it gets faster as the temp increases, but if one were to manually control the fans, couldnt you, at least in theory, help prevent the overheating problems many people have experienced by "preemptively" running the fans at a higher speed for a couple of minutes?

the only problem i see, at this point, with manually controlling the fans is if the temp sensor increases the speed after u have already done so...essentially running the fan so fast (whatever word is applicable) that it breaks...is this feasible?

if i'm barking up the wrong tree on this feel free to tell me...
 
If your goal is to prevent damage from overheating in a Macbook/Macbook Pro, there already is a firmware update that fixes the problem. It basically causes the fans to come on earlier (40ºC or so) and causes the fans to max when the CPU temp hits 60ºC. After the update, my CPU temp rarely ever hits 60, even while doing lots of intensive stuff, like compiling in the background while running Matlab through Rosetta.

On the other hand, if your goal is to just have manual control of the fan, I have no idea where to begin :). Fan controls are usually built into the firmware itself, hence the need for a firmware update.
 
how can i check if i have this firmware? was the update: "Version 1.0 of the MacBook Pro Firmware Update" ? I did a spotlight search and thats what came up....if thats right can u let me know? thnx
