    I can vouch for that. It's brilliant.

    I'm pretty sure you have started this thread because you tried smc fan control and it didn't work so well with the iMac. I found a program a few days ago specifically for the iMac which I use cal "iMac fan control" and it can be found here http://www.derman.com/Download/Special/iMacFanControl.html

    Hope this helps

    OP, are you sure that you have to boost up fan speeds? I recommend you to download iStat widget and tell your temperatures so we can see do you really need more cooling.

    agreed install istat first no real point having fan control and no fan monitoring :)

    a dont know for others but i have run smcfancontrol on 2 imacs for a long time with no issues

    I have had no SMC Fan Control on 3 Macs with no issues!

    It confuses me why people want to mess about the machine's own cooling system when it can manage perfectly well on its own.

    I agree. Yesterday when I was writing my earlier post I touched top of my iMac and it was boiling hot but when I looked from iStat my highest temperature was 53C and it was my hard drive, CPU was ~45C. It feels hot but it it really isn't. Aluminum is metal so I think it heats up too

    I do it on my Mini becasue I'm paranoid.... I've upgraded to a T7600 CPU and when I convert a bulk of videos for my wife's iPhone I set my minimum fan speed to 5000RPM - sure its noisy but the CPU doesn't get into the 80c range which makes me more comfortable than letting it run in the high eighties for hours if I let the OS manage cooling.

    there are billions of threads on this but anyway i cant stop myself :p ........i really think its case by case

    for normal everyday using the imac of course can deal with its heat...hellhammer is right of course the case is built to give out heat so just feeling the case doesnt tell you what is happening if you really want to know use istat or something like that....

    why would you use smcfancontrol then if the imac is fine??....well i think three possible things

    first if you want your imac to last a longer time than usual most people replace 2-4 years....if you want especially your hard drive to last more in the 4-6 year range then its not paranoid to consider internal hd temps

    second if you use your imac for stuff thats not email and youtube ie 24/7 rendering or other heavy work for long times....this will keep heats high for long periods and again internal hd lifespan will be affected

    third if you use your imac for windows for stuff thats not email and youtube.... fan control under bootcamped windows is not great and you can get a lot of heat from heavy gaming or other heavy software.....again for regular now-and-again use if you upgrade your machine every few years its probably no thing.....

    sooooo.... i think a lot of people touch their case and think they could fry and egg and get really scared about the imac melting..... thats normal imac operation

    but there are some prosumer type of uses for an imac which afterall is pretty powerful now where apples default fan/temp management might not be so good and in that case i think its sensible to use istat and smcfancontrol to monitor things

    my 2c :):)

    Good post aki. Is iMac's overheating a big problem? I think it's not. I've never seen a "iMac melted" thread here yet, so that's why I'm suspicious about speeding up the fan speeds. I can trust that OS X will speed 'em up if it's really needed and for the hard drive thing, I'm happy if my hard drive can last over 2 years because after that time, I'll be updating to SSD anyway and of course I have backups on my external. My almost 2 years old PC laptop's HD has died 2 times and it's hot as Pamela Anderson.
