VB Forum / Win API / October 2003Fan Speed
Are there any API so that I can control the speed of the cooling fan? thanks > Are there any API so that I can control the speed of the cooling fan? > thanks None that I know of. I have to ask....why on earth would you NEED to control this? You trying to cause somebody's computer to overheat? Mike thanks MikeD just oppositive my notebook sometimes reboots itself because of overheat it is supposed that when the temperature raise to a certain high level the cooling fan will operate itself, but this is not always the case This problems is solved when I use some programs like CPUCool to cool down the CPU But these programs are not bugs-free and often use up a lot of memory. I was thinking that if there is any simple API, WMI can be used to keep my cooling fan operate. I've tried to disable the power management functions of my notebooks but it don't works I found a WMI function Win32_Fan and CIM_Fan that controls the fan speed but I don't know how to use its method "setspeed" http://msdn.microsoft.com/library/default.asp?url=/library/en-us/wmisdk/wmi/cim_ fan.asp can anyone help me? thanks > > Are there any API so that I can control the speed of the cooling fan? > > thanks [quoted text clipped - 5 lines] > > Mike http://www.versiontracker.com/dyn/moreinfo/win/15598 http://www.mofunzone.com/downloadsoftware/4000000037948.shtml >thanks MikeD > [quoted text clipped - 39 lines] > > I'm not familiar with notebook hardware so I hope I'm not giving you useless advice here! But based on experience with PCs, assuming that the notebook is using some kind of motherboard: Even if WMI could do it the motherboard would need to have a built-in rheostat for the fan, which seems unlikely. If it were me I'd try the manufacturer's website and the motherboard website to see whether there might be fan-monitor and cooling software specific to the product. I've got an MSI board, for instance, and they make their own CPU-cooling software for their boards. It might be a little more tricky with a name-brand computer product because they often get custom-order components specific to their product, then neither the computer maker nor the component company wants to be responsible for support. It'd be worth checking into, though. -- -- > thanks MikeD > [quoted text clipped - 12 lines] > I found a WMI function Win32_Fan and CIM_Fan that controls the fan speed > but I don't know how to use its method "setspeed" http://msdn.microsoft.com/library/default.asp?url=/library/en-us/wmisdk/wmi/ cim_fan.asp > can anyone help me? > thanks [quoted text clipped - 9 lines] > > > > Mike |
