So then its a matter of the age of the drive does it offer the update or not if not you'll need the in-line sensor. I suspect this is related to the SMART update Apple was able to get in the standard. 2 and larger SSD's tend to get a a bit warmer! I strongly recommend putting in the OWC in-line sensor so the system is able to aggressively cool the system when the SSD gets too warm.Ģ013 and newer 27" iMac's with newer firmware appear to not to need the inline sensor. While using a Y connector cable can resolve the need for the OWC in-line sensor adapter it should only be used when the 3.5" drive is replaced with a 2.5" SSD and nothing larger than 1 TB. It took awhile but the most of the current 2.5" drives incorporate the update so there is no issues. Apple proposed to the standards group an update too SMART. these are laptop drives which run cooler as they are slower RPM drives. You can do this by downloading HDD Fan Control and running the installer. Hard disk, SSD and OpenCL GPGPU video adapter stress testing is also available. Support Updated to OS X Yosemite or newer If you have updated to OS X Yosemite or newer from an earlier version of OS X, you will need to update to HDD Fan Control 2.5 or newer. it can gather accurate voltage, temperature and fan speed readings. A 2012 and newer 21.5" models use a 2.5" drive. HDD Fan Control Reduce Fan Noise and Protect your Drive. The 2012 & 13 27" also uses a 3.5" drive and requires the inline sensor as the drives heat needs to be dealt with. With the SSD in place now, the only thing I can hear is my breath reflected by the glass screenĪ 2011 and older models use a 3.5" drive which requires the sensor. Your fans are always on when your Mac is on, spinning at a minimum of 2000 rpm (for MBPs) or 1800 rpm (for MBAs, MBs and minis). I went further and moved the internal HDD from SATA0 to SATA1 port to better accommodate the SATA connector for the SSD and this didn't create any adverse effects.Īnother member of the forum swapped the 1TB WD Black with a 2TB WD Black and again, no adverse effect, Hardware Test completed successfully. Guess what, fan speed is as quiet as it can get and the Apple Hardware Test passes successfully. I installed a Vertex3 SSD and used a plain 4 wire Y-splitter sata power cable which effectively discards the 3.3V from the apple's wiring and only feeds 5V and 12V to the original drive. The only difference is that they used 7 wires instead of 5, probably some extra grounds. The SATA data connectors are very standard and so is the SATA power cable feeding the hard drive. The OWC report is quite inaccurate and I wish they did some more testing or at least read the forums before creating mass panic. Sets fan speed for Hard Drive Temperature Runs the fan at a speed appropriate for the HDD or SSD's actual temperature. You can artificially increase the fan speed to further reduce the CPU's heat, but this will also increase fan noise.I'm copying a post comment in Appleinsider: HDD Fan Control directly controls the speed of the HDD Fan slowing it down when the drive is cool, and speeding it up to protect the drive from overheating when hot. The only iMac HDD upgrade option on the market certified to pass. Your Mac might run slower, but there's nothing to worry about. Eliminate fan noise and maintain correct system fan control when upgrading your 2011 iMac. When your Mac gets hot, it starts throttling your CPU until the temperature gets under control. Some Caveats Before You Start Controlling Fans
