Faulty CPU/ODD sensors or fans after Dual Drive Kit Upgrade
crwdns2934249:0crwdne2934249:0:
Hello,
I performed the '''Dual Hard Drive Kit''' upgrade as suggested in the guide at [guide|7575]
I followed the steps precisely during the whole process.
After the second drive (SSD) was installed, I booted up the iMac and heard loud fan noise after a few seconds. '''Both CPU and ODD fans are running at full speed.'''
I have tried resetting SMC/PRAM, but to no avail. I reassembled the logic board twice, with and without the Dual Drive Kit upgrade. It still didn't fix the problem.
So, I believe something somewhere has gone wrong and I need to identify the problem and fix it.
I have also noticed that it is not just the fans that are loud, my game which I play every day at 30fps, is crawling at 6-7fps after the upgrade (still utilizing the HDD though, not the SSD).
Running the '''Apple Hardware Test''' revealed failure with '''TA0P''' code, which indicates Ambient Temperature sensor/connector failure according to some google search results.
Moreover, Temperature Gauge Pro app reports the following:
'''ODD''' 3729 RPM
'''HDD''' 1097 RPM
'''CPU''' 3917 RPM
'''Fan Diagnostics''': These fans appear to be not working properly : ODD
'''Sensor Diagnostics''': These sensors appear to be not working properly : CPU
Some further Googling has revealed that this person had a similar problem and flipping the '''LCD Thermal Sensor Cable''' fixed it for him: http://forums.macrumors.com/showpost.php?p=16423197&postcount=13
However, I'm not sure which of the cables mentioned in the iFixit guide are the LCD Thermal Sensor Cable, for me to give it a go (I doubt any of the cables can be flipped on this model though).
Any help would be appreciated.
'''TLDR''':
* After installing 2nd drive (SSD) on 2011 27'' iMac,
* CPU and ODD fans are running at full speed, HDD fan at normal.
* Degraded gaming performance at 6-7fps.
* Failure in Apple Hardware Test with code TA0p.
* Something somewhere went wrong in assembling/disassembling (perhaps).
Thanks!

I removed the LCD panel from the iMac and booted it with external Cinema Display. The fans are still loud. So I doubt that the problem is with LCD sensor. Maybe I should pay attention to the Ambient Sensor/connector, since the AHT failure also reported a fault with that.
