With SMC Fan control my HD temps have dropped from almost 130degrees Fahrenheit to anywhere from 102-120 degrees Fahnrenheit. At idle or less intensive applications, the CPU temps are between 95-102 degrees or so Fahrenheit. The CPU temp has dropped to around 110-115 degrees Fahrenheit. At idle, the PSU rests at a comfortable 132-135 degrees Fahrenheit. With the fans running in this range and using Photoshop, my PSU temps have dropped to 135-140 or so degrees. This range also keeps my iMacs fans from sucking in excessive lint, dust and dirt. Hardly speeds that would prematurely burn the fans up. True, the fans run at this constant speed, but the fans are running only at 40%-50% faster rate. I run SMC fan control within a 1600-1800 rpm range. These temps IMO, are completely unacceptable. Plus,the GPU heat sink and diode and the PSU without any fan control was running between 145 and 159 degrees Fahrenheit. 122-140 degrees Fahrenheit is not very cool. I do not consider 50 to 60 degrees C very cool for any component. I'll live with some minimum level of fan noise to obtain a cooler running iMac.Ĭompared to my old G4 MDD Wind Tunnel model, even with some noticeable fan noise, my iMac is still much quieter. I do not care about completely quiet operation. Too much extra complication for a simple fan control task. What I've noticed is that the iMac power supply is what gets overtemperature before anything ese does and so with the lower threshold set to 45° that nudges the fans up which keeps the CPU in a very cool 50's* range which compensates at keeping the power supply in a happy low 60's° range. I have the lower and upper thresholds set at 45° and 65° and the fan speed lowest and the iMac runs very cool and rarely do I hear the fans spooling up. You might want to try it on your iMac and get rid of SmcFanControl. but the Derman version of Fan Control has an iMac version that works beautifully and idles the fans low and cycles them up as needed to keep it cool.

I initially used SmcFanControl but it still allowed the iMac to get too hot since it's only a simple manual adjustment and it keeps the fans running at a constant higher speed all the time which I don't like as far as fan wear and sucking in more dust goes.

My MacBook Pro fans act normal and speed up when it gets hot. The thing is that the iMac fans never speed up at all and it overheats and will shutdown eventually. I make sure that I observe ESD practices with ground straps. If any of my Macs get dirty inside I'll carefully take them apart and vacuum and blow out the filth. I was just checking, not many folks think to even clean the dust off the intake grills regularly must less the insides.

And I have had it apart to change the hard disk and there was only a small amount of very fine dust to clean out and nothing more.

I'm also using Fan Control on my 2010 Mac Mini in hopes that it too will last as long or longer than my iMac.īut if you must know it's very clean inside and operates in a house that has high end air purifiers and is nearly dust free. I am with you and also believe that cooler hardware will last longer.! That's why I've been using SMCFanControl on my 2006 iMac for over 6 years, which seems to have paid off. Problem is, that eventually it comes at a price and after a few years (5+ in your case) the hardware begins to suffer. I'm not sure why Apple has the thresholds set up so high, perhaps to maintain a quieter all-in-one system than it's competitors. This doesn't address the problem of the fans not speeding up when it's hot at all. Why can this control panel speed up and control the fans just fine and effectively cool the iMac but left to it's default control it does nothing and allows the iMac to overheat? And has anyone had this problem and found a way to fix it? Many people seem to like SmcFanControl for some reason but I don't because it's crude and totally manual in setting the base fan speed which keeps the fan running higher than normal all the time but doesn't help much to cool if the iMac gets really hot unless you manually speed up the fan more. The one I chose as the best was Derman's version of Fan Control, a control panel which is automatic and effectively keeps all the temperatures normal and has been my solution to the problem. Then I found some of these apps that let you control the fan speed manually or customize the threshold and with some of these I was able to speed the fans up.

It was a while before I had installed software that measured temperatures of devices or fan speeds inside the iMac and then determine what was happening and that indeed the iMac would shut off when the power supply got too hot. I have a 2007 iMac that for some reason the fans won't speed up above idle and so if it's put to heavy use eventually it will overheat and shutdown.
