Out-of-control fan speed is commonly reported after swapping hard drives or installing SSDs in recent-model intel Macs. Version 2.12 of this freeware: SSD Fan Control at http://exirion.net/ssdfanctrl/ appears to give users the ability to reduce the fan speed on iMac systems by overriding System Management Control (SMC) of the hard drive and optical drive heat sensors and relying on S.M.A.R.T. reports of internal temperatures. If you've used exirion's SSD Fan Control on your iMac, Mac Mini, or MacBook Pro, could you please report on your experience? The developer's web site provides no un-install instructions. I'm reluctant to install freeware that has no instructions for clean removal, especially in the absence of user reviews. If the developer is monitoring this forum, would you kindly provide un-install instructions here and on your web site? Many thanks.
