With older CD Recoders, I 've cut-out a hole in the bottom, of the drive, and mounted a CPU fan to pull the heat from inside the drive unit out. All problems were corrected.
With the LTR -52327S, I couldn't do a successful overburn, after system was on for more than a half-an-hour, or if I burned a few CD's. So I would turn the system off, for a half-an-hour let it cool down, start the system up and do a successful overburn up to 99minutes, regardless the size of video.
So I adapted the above method, by cutting a hole with four little mounting holes, put a 3200 RPM CPU fan, to pull the heat from within the drive unit out. Now I can Overburn as many CD's I desire.
I believe Lite-on has a engineering flaw in their design.
I experienced this with other CD Burners.
