I don’t knwo what’s the aim of the question. Do you think your Notebook will “overheat” (CPU, HDD,…) or do you think the burner will overheat if you burn one disk after the other for a longer period?
Basically there is an possibility of overheating a CD/DVD brive by using it. I converted my CD collection to MP3 and my CD Burner was really HOT. This is as far as I know normal, CD and DVD drives are not designed for a 24h / 365 day usage with no pause. This is by design.
When I remember correct CDex or was it EAC has a feature that makes after ripping a specified number of CDs a break to cool down the drive.
But if you are burning 3 or 4 disks with no break there should be no problem, I did it with my Samsung P35 Notebook and with my Plextir drives also. I did not burn CDs or DVD for hours and hours.
This cooling devices are not very effective since only the outer case of the notebook will be cooled. I know there are people saying there is nothing better for a Notebook to cool it down, but in my opinion it is waste of money. It is more effective to open the Notebook and clean the fan and heatsink in case the Notebook is getting too hot. A lot of dust will be in the heatsink and at the fan and the cooling is therefore not very efficient.
