HP Pavilion dv7-4083cl (w/ Intel Core i5 and ATI GPU): Which is its normal temperature?

Question

Hello,
I have a question about HP Pavilion dv7-4083cl (w/ Intel Core i5 and ATI GPU):
Which is its normal temperature?
Environment: 24 °C (Celcius)
HWMonitor and Real Temp agrees with the numbers find below.
The two CPU Cores starts at 37 °C and in about an hour are at 53 °C, with CPU usage under 10%.
The GPU starts at 34 °C and easly goes to 57 °C, with some peaks at 72 °C
Regarding "Hewlett-Packard 144B": (under low/idle CPU usage)
TZ01: starts at 40 °C and very fast goes to 55 °C or 65 °C (and more, under CPU load)
PCH starts at 59 °C and very fast goes to 76 °C (and stays there)
GMCH: starts at 40 °C and very fast goes to 55 °C or 65 °C
ATI Mobility Radeon HD 5470 (TMPIN0): Starts at 34 °C and easily goes and stays at 57-58 °C
Note: I'm also using a cooler (two fans, under its base)
If I run Real Temp (v. 3.6) "Sensor Test", the cores goes up to 100 °C , and even a bit more.
Which is the normal / expected behavior / operational range?
Steady PCH at 76 °C is it normal?
TZ01, GMCH at 55 - 65 °C is it normal?
i5 Cores at 55 °C is it normal? (and easily going to 70 °C or more)
GPU (ATI) at 57 °C is it normal?
is it normal to climb up to 100-105 °C under a 5 minutes high CPU usage operation?
Thanks!

i roll back to bios F.25 which is the older version of bios that support my device but still suffering from same D90 system overheating error.
i can't contact hp support or send it to offical hp center currently coz i am from Egypt and i live in far town
