Recently I replaced my MBP Mid-2010 HDD with a Zotac 480G Premium SSD. Things are really faster now, but one thing I noticed is that the CPU rises to peaks quite unprecedented with my original HDD. In video conversion, the CPU temperature soars to 95 degrees Celsius but the fans seem sluggish to kick in before the CPU temperature is 85 or so. The GPU temperature is also quite high. Of course, after they start spinning up they both work around 6000, but they cannot lower the CPU temperature below 92 degrees Celsius. I have stared to think of putting the HDD back. In idle mode while I am not working with my mac, the CPU temp is around 49, but on startup and when working with apps like pages the temperature is around 66 degrees.
What do think? When do your fans usually kick in while you are having a cpu-intensive process running in your mac?
Update: Here are two images related to CPU usage and temperature. I hope it helps.

It is not a problem that your CPU is at 95 degrees celcicus for a short period of time.
The mid-2010 MacBook Pro with Core i5 processor is specified to withstand up to 105 degrees.
So unless you have some kind of practical problem (for example the underside of the laptop being too hot to handle), there's really nothing to worry about.
