I’d like to personally address some questions, context, and provide additional technical detail concerning this issue. We can upgrade to their 6000 series for 315 more.It’s incredible the coverage generated by yesterday’s blog article on the further iMac upgrade restrictions. The Weather Lok came in at 5350.00 and the Window World 4000 series came in at 6050. WE need to replace nine windows, all single hung, nothing too fancy in terms of size and shape. Dane, I have two quotes - one for Weather Lok and the other for Alside windows.

Western Digital WD2002FAEX 2.0TB 7200RPM Caviar Black 64MB Cache 6Gbp/s Noise from the fans themselves.In my opinion, the following should be an industry standard thing…. The noise I observed is more from actual air movement through the channels vs. While the fans are definitely noticeable in an quiet space, Apple does use fans that are very quiet even at higher speeds. Not being able to run Apple AHT can be a detriment in this way, although admittedly something that many can do just as well without.Depending on your environment, this may not matter. If you can not run this test, it could impact support or even warranty response for an iMac with an issue unrelated to the hard drive. Certainly in a production environment, you want to know your system is 100% go-go-go. The ambient temperature of the room being tested in was between 72 and 76 F.Apple AHT – why this not working can be a problem:When you have a problem with your system, Apple Hardware Test is often suggested for determining if the problem is… well… with a hardware component. The other bays:First, note that the HD bay has a different power connection with seven total leads, two of which are used for thermal feedback. Maybe someone out there has insight on Apple not using the thermal data via S.M.A.R.T.?What’s different between the power connection/leads for the HD bay vs. There is still a question I’d like to know the answer to – why isn’t Apple simply using the S.M.A.R.T. reporting feature of today’s drives for the drive temperature information? That doesn’t require/use any extra pin out/line out and I am not aware of any disadvantage from utilizing this option. If so – it might not be as big a deal. So, perhaps use of this additional line on the power connector (which is standard on all SATA drives) might be an industry standard in the future.And if so – then it’s only Apple today, with a firmware set that enables this feature, which just isn’t standard on retail drives yet. They could also use a different make, but they would need to make some modifications.What I am trying to say is that Apple didn’t make any barrier with the 2010 (or 2009) models with that respect, the barrier to plug & play drive options in this case is a lack of industry drive standards on the extra drive pins. Mac lion server torrentNoting that external thermal sensors provide the thermal data by voltage passed – with resistance on the line affected by the temperature of the sensor that results in voltage read change, so still could be a standardized industry function future forward…. Furthermore,when we connect up a drive that was not originally shipped in one of these iMac 2011 models, the pulse pattern is no longer present.Although the differences between drive brands here raise questions about possibility of industry standardization, the fundamentals appear similar – just a different starting voltage possibly. What’s interesting is that the voltage range, and this is contradictive to my suggestion this could be a future industry standard thing, is that the different brand drives have a different ‘hold voltage’ and ‘drop pulse’ range observed. When you do this though, our best guess is that the thermal reporting in the iMac is being told that the bay is empty. We have been aware of this and see upgraders in the field now reporting this as well. Connect to the drive (factory or otherwise), the fans don’t rev and Apple AHT does pass. We have done other testing with external options, but it’s so far inconclusive – so can’t say anything is 100% definite yet other than: either Apple has custom firmware in its drives that enables something, or Apple has firmware on the drives that it looks for to use what is there anyway.*NOTE – NOT FULLY TESTED/Approved/Recommended, etc.* I strongly caution, we’re looking at a number of scenarios and doing a lot of testing to determine what is going to make sense and be reliable and implemented in a way that best maintains the Apple warranty on the system as well.If we short those two lines vs. Ok, that’s pretty confusing…. Data to monitor drive temperature and allows you to set the temperature parameters for what speed the HDD bay fan runs at. The bottom line is that the iMac HDD bay can heat up and the iMac doesn’t know and doesn’t do anything about it.HDD Fan Control appears to be another option and a solution to the above.This utility uses the S.M.A.R.T. Of which, a consequence could ensue for obvious reasons. Combine that with the short solution above, and you appear to have an iMac with fans under control and that you can run Apple Hardware Test (AHT) with normal results.One concern with using any utility to limit the fan speed is what if your settings are too low for heat? We don’t know Apple’s exact parameters or collected data points from the HDD bay for thermal, and there is a potential for issues should the bay be allowed to become too warm without the proper fan speed engaging. Data?By itself, this software can solve the fan rev up issue. Again, th0ugh, why doesn’t Apple use S.M.A.R.T.
