SSD on MacBook Pro (early 2008) heat?

I've upgraded my HD with a Samsung 830 SSD. The operation was made by an authorized apple tech that told me that everything was working fine.

Then I restored my system and installed Trim Enabler as suggested.

I noticed that my CPU temp is higher than before (now 60-70 C°) and when it boots, sometimes I hear fans increase their speed. What's wrong? I've already did a PRAM and a SMC reset without results. I'll discuss this on Monday with the tech that did the job but in the meantime I'd like to have your opinion.

Thank you

 MacBook Pro 2.4GHz (Penryn), Mac OS X (10.6.8)

When first moving, reinstalling, the OS Spotlight will index the new/moved install and that can take a period of time for it to complete. While that is happening you will get higher then normal CPU activity which will cause more heat to be generated. If it continues for days then you may have some other problem, some software may be hung in some way sucking up CPU cycles.

Check Activity Monitor to see what is using the CPU cycles.

Thanks. Activity Monitor looks normal and Spotlight has already indexed my disk.

It's strange, though. The MBP was turned off for 2h and now right after boot, CPU's temp is 45-50° and it is doing nothing special. Usually it should be around 25-30 at this moment...

Any ideas?

UPDATE

My MacBook seems to be running ok... temp is fine, fans are all right (round 2000) and the battery looks slightly improved. I really don't know what happened but I hope to figure it out on Monday at the Apple store.

do you use a macbookpro4,1 (15" early 2008)? I just bought a Samsung 830 SSD, too and my dealer told me to check the forums first before I open the SSD package, because some macbooks don't work with all SSD's..

Thanks!

Yes, MBP 4,1 with Samsung SSD 830.

It's running fine, consider that we have SATA 1.5Gb/s so with a more recent Mac you'll take full speed (6G).

I've installed Trimenabler utility and I had no problems so far.

awesome, thanks for the quick reply.

Did you make a clean install of Snow Leopard with the install DVD after putting the SSD in the MBP or did you copy your old HDD to the Samsung in an external enclosure and made the installation in the MBP afterwards?

Or did you use a Lion DVD/USB Stick?

At first I've restored a carbon copy of SL but then I performed a clean install because I had a messy system.

Now I've upgraded to Mountain Lion and it runs great!

ok, but too bad that we don't get AirPlay Mirroring to the Apple TV

Did the tests. Everything looks ok at the Apple Store too.

Now I've also upgraded to ML and the computer is running fine, maybe even cooler than Lion.

I just installed the SSD (and a 1 TB HDD at the SuperDrive Bay with an Adapter and migrated my old harddrive to these two drives (User Dir on HDD, System and Programs on SSD), runs smooth and without any problems yet

Another thing to keep in mind, with an SSD, the CPU is going to spend a lot more time waiting for disk i/o, and so, for some tasks, like reindexing spotlight, it will run hotter, but the task won't take as long.
