Overheating: BIOS vs T4x Fan Controller?

[dav1129]

I first came across TP4x Fan Control utility inadvertently after my T23 started to cut out from time to time and I had no idea why. As I learnt why this maybe happening I went back and replaced the thermal grease between the CPU and the fan which following the T23 Hardware manual I removed while replacing the LCD backlight (which is now fixed).
The reapplication of thermal grease has certainly improved the heat levels and I am no longer running T4x Fan Control as I did before (heat is my only concern, not noise).
However left to the Embedded Controller I just witnessed the CPU temperature rise to 99C and the thermal protection as expected, cut in.

Is there no permanent fix or do I need to adjust the settings to suit and run TP Fan Control permanently?

But then given that TP4x Fan Control while in SMART mode hands back control to the BIOS at 70C AND as I just experienced my BIOS didn't manage the rising temperature why would running TP Fan Control help?

Or is Artic Silver paste which I was unable to get here much better than other pastes?

If the answer is that I have to run Fan Control permanently to avoid temperatures as high as 99C again, these are the settings I am using at the moment.

Level=30 0
Level=35 1
Level=40 2
Level=45 3
Level=50 4
Level=55 5
Level=60 6
Level=65 7
Level=70 128

Thanks for reading or replying to my post

PS I am not a gamer, this T23 is just for general office use, sending email, browing the Internet and watching movies and has already upgraded to the latest official BIOS version.
