Do the temperatures indicate my laptop healthy?

The temperatures of my Thinkpad T400 are:

acpitz-virtual-0
Adapter: Virtual device
CPU_0:        +57.0°C  (crit = +127.0°C)
CPU_1:        +56.0°C  (crit = +100.0°C)

thinkpad-isa-0000
Adapter: ISA adapter
Fan:                                                   2939 RPM
CPU neighbourhood (also via ACPI THM0):                 +57.0°C  
Ultrabay:                                               +51.0°C  
Express card:                                           +38.0°C  
ATI graphics module:                                    +73.0°C  
Main battery (always around 50°C):                     +36.0°C  
n/a (probably ultrabay battery):                            N/A  
Main Battery (fits about the value reported by smapi):  +33.0°C  
n/a (probably ultrabay battery):                            N/A  
Hard disc:                                              +40.0°C  
Intel graphics module:                                  +48.0°C  
Heatsink?:                                              +46.0°C  
n/a:                                                        N/A  
n/a:                                                        N/A  
n/a:                                                        N/A  
n/a:                                                        N/A  
n/a:                                                        N/A

I wonder why ATI graphics module has the highest temperature +73.0°C?

Do the temperatures indicate my laptop healthy? Do I have to worry about them?

What steps shall I take to make it healthy?

Note: They are achieved when I use a cooler and scale the cpu frequency to the lowest 0.8GHz. WIthout a cooler, the highest temperature will be over 80 celcius. If further without cpu freq scaling, the highest can be 90 and 100 celcius.

Thanks.

173 isn't bad at all, unless you're only editing excel spreadsheets or surfing. Make sure the airflow is dust-free, strip the heatsink & replace the thermal paste with high-quality if in any doubt [not a job for a beginner] – Tetsujin – 2014-10-19T17:22:24.200

(1) How high temperatures will I need to worry about? (2) the reported temperatures are when I am opening 100 tabs in chrome browser now. They are achieved when I use a cooler and scale the cpu frequency to the lowest 0.8GHz. WIhtout a cooler, the highest temperature will be over 80 celcius. If further without cpu freq scaling, the highest can be 90 and 100 celcius. – Tim – 2014-10-19T17:23:43.843

I'd reallyworry at 100; but I would have done something about it long before that. 2) Chrome will eat CPU, not GPU. Only the front-most window should eat GPU, eg if it's running video [& still not much] CPU frequency has no bearing on it. Cheap thermal paste has a lot to answer for.

Is "ATI graphics module" GPU? How can I scale GPU frequency under ubuntu? – Tim – 2014-10-19T17:37:33.467

idk, sorry. Never used Ubuntu. – Tetsujin – 2014-10-19T17:38:34.133

Without cpu freq scaling, the max is achieved by CPU. I guess "ATI graphics module" is GPU? – Tim – 2014-10-19T17:43:14.813

GPU == Graphical processing Unit == "ATI graphics module" – Tetsujin – 2014-10-19T17:44:36.277

Try installing the FGLRX driver.My laptop idled at 65C before installing and after installing it idles at 49C (and GPU is 47C , GPU is the APU integrated graphics) – Suici Doga – 2016-07-30T04:54:52.983
