is my laptop heating?

i have a hp compaq 6720s laptop with 1.6 dual core processor,1Gb RAM with 120 Gb harddisk.
i use speedfan to monitor my laptop temperature. so at room temperature of 25-28, here is what i get from speedfan.

local temp:- 42C
remote temp:- 48C
HD0:- 42C
temp1:- 42C
temp2:- 29C
temp3:- 21C
temp4:- 53C (this is my concern)
temp5:- 50C (this too)
core0:-50C (this too)

is these temperatures normal? i am concerned about temp4,temp5 and core0 temperatures. please help me.thanks

 

I use HWMonitor

I have a inspiron 530 desktop.
intel core 2 quad 6600 2.4ghz
gpu XFX 9600 gt
A thermaltake power supply 550wats
6GB ram
600gb HD
a windows vista home premium 64bit


My TMPIN0 at the HWMONITOR shows 85C at startup and stays around that even while I'm playing.
I've being like that for about 3 months with no problems at all, I think the program is crazy, tried speedfan also and it shows the same temperature.

How do I make sure it's true?
I play BF2 every day and Crysis also, my system never froze, start up fast and turn off fast.

If true how do I fix it without damaging the airflow in the case?
I clean the case every three months for dust build up, so it's really clean.


I spoke to a dell representative and he said not to worry because they didn't know if the reading on the software were true and it shouldn't be because the system runs great. but still I'm concerned. I'll post a picture of the readings larter.

I appreciate any help.
thanks!

 

what is the problem with my laptop temperature?

i have a core2 dual processor 1.6. the problem is this that the temperature of the cores change each second. like if it is 45 then 54 then 53 then 45 then 50........like this it changes continuously....is this normal or is there any problem with my temperature sensors.
any kind of help will be appreciated.
P.S. i use speedfan, HW monitor to check my temperatures. and my laptop is new.

 

My laptop runs about the same if i leave it on a flat surface but all i do is raise the back of the laptop about 1 inch by placing a book under the back and this allows a better airflow.
