    I've recently uninstalled Fan Control and smcFanControl from my Macbook Pro, after trying them for a minute or two. I reset my SMC by using the method on Apples website (Clicking Shift-CTRL-Option-Power Button at the same time).

    It havent worked it seem, as I have tried running some games and even at 85-90C degree, its not increasing its RPM. I dont wanna go any higher as I dont wanna risk the CPU overheating.

    Any suggestions on what I can do?

    I noticed the same problem yesterday but I am using iStat Menus. I was heating up to about 87 and the fans didnt kick on past the normal 2000 rpms. Makes me wonder whether or not all this 3rd party fan control is doing more harm than good.

    Doesn't iStat Menus simply keep track of the fans current RPM, rather than being able to adjust it?

    Either way, im still looking for possible solutions.

    The fans won't spin faster unless a high enough temp is sustained for a period of time. They won't necessarily spin up if you hit high temps for brief periods. 85-90C is not an unusually high temp.

    The lastest (non-free) version of iStat menus does include a fan control option in its settings.

    Why'd you delete smcfancontrol to begin with?

    When I read the smcfancontol documents, it states that it still allows the macbook to increase fan speed under load, it just allows you to set the minimum fan speed to a higher level (e.g. - 4000 rpm vs. 2000 rpm).

    i've never heard my macbook pro fans spin up ever. i've had it for a month. should i be worried? i was playing tf2 the other day and the temps were in the 80's (celcius) and the fans stayed at 2k rpm, as far as i can tell. is this normal?

    what temperatures do the fans actually get going?

    Yes, that's normal. It's not that the fans will spin up when a target temp is reached. There are sensors that monitor temps of GPU, CPU, etc. and your system knows what temps need to be reached and for what duration before the fans will spin faster. Your MBP can monitor and manage the temps much better than any user can. Just let it do what it does.
