CPU's normal temperature

Hi everybody,I have some questions about the temperature of CPU.
My Acer Aspire 1642wlmi is 2 months old and i am worried about the temperatures.Normal temperature of CPU is 52-54'C and in full load goes up to 70'C.
The CPU is a Pentium M 740 and i have 1Gb RAM.Is it normal to be so hot?
And one more thing,I have Notebook Hardware Control software to monitor the temps,so I have decreased the voltages so it won't be so hot.
So it's like this: 6x=0.780v; 8x=0,812v; 9x=0,924v; 10x=0,972v;11x=1,020v;12x=1,068v;13x=1,132v.
Is it good what i did? Can everybody give me some answers?

Thank you very much,re5pect Danutz.

 

As far as I know, pentium m is very well known to run extremely hot,also my ASUS W3J with the Core Duo (1.66 T2300) CPU once reached the 70 degress under extremely heavy load.Refer to your CPU specs in Intel site , I think the 100 degrees is the limit,if the temps worry you, you might want to use a cooling pad at home.

 

Those are not particularly hot temperatures. I think you should be fine with that.

 

That undervolt sounds about right, assuming it's about 0.2 volts below the default for each step.

I'd say that the idle temp is ok but the load temp is on the hot side. This barely gets above 60 on full load! The undervolt should help but I'd also recomment a cooling pad if you intend to do a lot og gaming. Long periods at 70C will do your cpu no good at all.

 

I also think the load temperature is quite a bit high, as jess_paws has pointed out. 70 C is within thermal limits, but it is quite hot for the processor to reach. Make sure that inlet and outlet vents for the fans are blocked.

As the other members have said, it will be worth it to invest in a cooling pad. They reduce temperatures, and will also prolong the life of many components in your notebook.

 

Those temperatures are fine for your notebook; Acers are known to run warm.

Undervolting as posted can help your temperatures and will reduce power consumption; take a look at the cooling guide, where I showed how to do some Pentium M overclocking. I never had any problems with my underclocked Pentium M 750.

 

Thank you very much everybody!
If I change the voltages with 0.200v under the normal,the temperatures are in normal use 48-50'C and in maxim load(cca 5 min in max load),it's 57-59'C.
If you think that there's no problem,I think I will leave it like this.

 

As long as your OS run stable, there is no reason for not using undervolte whatsoever. I use it all the time, and never gives me any trouble. My normal use temp never higher than 50C. The Pentium M is know to have good undervolte result than others. Core Duo and Core 2 Duo locked their minimum voltage, can't do much about them.

 

Your temperatures were fine as noted. Acer's are known to run a little warm anyway. Chaz's cooling guide is definitely worth reading through--if not just for the fan cleaning section. You should do that regularly anyway.

 

Rule #1: If the computer does not crash or is otherwise unstable, it is not overheating.
Rule #2: See #1.

 

Intel's TAT program products the highest CPU temps on my dv9000t. 39% C for CPU and 34% for HDD. I use the Valmam NC-1000 cooler. This cooler smokes.

I found a REAL and SIMPLE solution to my
HIGH-TEMPERATURE problems in Notebooks:

200°F / 93°C was reached when I really got nervous.

At first I thought, my new harddisk or even Linux
is to blame (my first Linux installation in years),
but then the same problem occured in Windows, too.

My "test" was simple, I compressed 4GB of files
(a copied XP installation) from an external drive
into a ZIP file on the built-in harddisk
- that heats up the harddisk AND the CPU.

The only way to lower the CPU temperature was to
decrease the CPU-speed to 25%/50% - but that also
decreased the fan-speed. Then I downloaded several
fan/CPU-manipulators, none of them was able to
decrease CPU-speed while increasing fan-speed.

When I read about someone who renewed the "toasted"
thermal compound between heatsink and processor,
I actually opened my notebook (after switching OFF!!!),
and tryed to unscrew everything. Fortunately, one screw
refused! I would have broken the waranty seal later...


Then the idea: Blow IN air!
From the outside, INTO the opened notebook bottom.

The fan started to turn with a rather beautiful sound
(turning backwards), and a HUGE amount of dust came
out. 20 months of usage pressed so much dust into the
grating, that the fan could not push out air anymore!

I repeated the above test.

63°C / 145°F is the maximum at which CPU temp stagnates now.

30 degrees Celsius less! The easiest "repair" of my life.
I guess I have just prolonged the life of my notebook.

Haaaappppyyy! I am a genius

So now, please repeat this test with your used notebook.
By how much can you decrease the temperature?
