I installed a dual SSD+HDD setup in my MBP 13'' mid 2009; However I noticed a big increase in CPU temperatures, my computer normally sits at 55-60C when idle, now it's at 70-75C, is this normal? Any suggestions?
Is this a good question?

I exchanged the SSD to the optical bay and the HDD to the main bay and it seems it worked. The temperature dropped to an amazing 45C. Hope it stays that way.
Thanks Dan.

Sorry if a i"m a bit stubborn, but in the Activity Monitor the Finder process didn't seem to be working any extra or anything, and if you don't mind am asking, why the HDD is suposed to be in the optical drive?.
Thanks
Not a problem ;-} The I/O on the systems HD connector is faster SATA-III Vs SATA-II, some systems also have problems with the SDD booting from the optical bay I/O. You could double check your EFI firmware here's the TN on it: http://support.apple.com/kb/HT1237. For the CPU to get hot in one config vs the other there has to be something running to cause it to be processing. The only thing would be Spotlight indexing as the I/O port had been changed. Most people don't notice it as they don't have a as full a drive or one that is highly fragmented.
Thanks a lot for the explanation, it makes a lot of sense. However if I'm not wrong the MBP 13'' mid-2009 ports are both SATA II in optical and main bay, if this is correct it would not matter in which bay the HDD is connected?
As long as it works as you expect it doesn't matter which way you set it up.

The only thing would be spotlight re-indexing but that should take to long to do. You could try looking at the processes running to double check.
Otherwise it sounds like you dislodged some dust in the process that is now causing the CPU to heat up. The best thing here is to open up the system again and do a through job of cleaning up the dust buildup on the logic board, fan's and heat sink grills. I would also make the effort on re-greasing the heat sinks (cleaning off all of the old grease throughly).

The activity monitor looks normal and the processes are also behaving normally, I'll try reopening the computer to make sure everything is clean
If that is the case then it sounds like spotlight was running as the indexer needed to switch between the port ID's the drive is not connected to and since you reverted it only has to reindex what it had changed back. It sounds like you have a very full disk and you may infact need to do some house keeping getting rid of some old stuff, testing for bad blocks & defraging the disk. Make sure you have a good full back up and do that now then swap the disks back so the HD is in the optical carrier (best place for it) and let it run the indexer.

How did you setup your HD & SSD, did you put the HD into the optical carrier?
by Dan
Yep, the SSD in the original HDD bay and the HDD in the optical bay. However the HDD is running in smooth temperature (35C according to iStat)
