I use the Titan Ideal (500-850mhz) and normaly i don't have any problems due to heat or bad crashes.
Though i noticed 2 major crashes. After a 5 minute videocall on skype phone reboots and the videorecording aplication crahes after 1-2 minutes of video capturing.
I just wanted to know if anyone of you had the same issues...

I am thinking of going back to a non titan kernel or going to up to 900mhz. What do you think of that? (I had the customs kernels from Unlockr for a month and worked fine)

Update: After changing the limits on Titan to (500-900mhz) videorecording didn't even crash after recording 6++ minutes. (Normaly crashed after a minute or so) After 6 minutes of recording i stopped the recording myself.
