Temperature Issues -- Long Live My Lap...

lolilolicon · 2009-05-10 01:25:03

I just couldn't stand it! My laptop was really hot! So I'm working around with power management / CPU control and stuff.
It's an asus laptop, just got cpufreq to work, reduced CPU temp from 70+C to ~60C, but I've seen some posts here showing CPU temp @ 30~40 C, and some consider 40+ to be hot... Though normally, laptops are bound to get hotter than dektops, I don know, just to make sure.

Besides buying a cooler, blowing with electric fans, or tug it into a fridge, do you guys have a easier cheaper solution just to cool my poor lap down?

CPU :: Intel(R) Core(TM)2 Duo CPU T5450 @ 1.66GHz ::

$ sensors
acpitz-virtual-0
Adapter: Virtual device
temp1:       +61.0°C  (crit = +105.0°C)                  

coretemp-isa-0000
Adapter: ISA adapter
Core 0:      +59.0°C  (high = +85.0°C, crit = +85.0°C)  

coretemp-isa-0001
Adapter: ISA adapter
Core 1:      +60.0°C  (high = +85.0°C, crit = +85.0°C)

BTW, why don't I get other stuff by sensors, like fan speed etc. Is there a way to get it for my asus laptop?
HDD

sudo hddtemp /dev/sda
/dev/sda: Hitachi HTS542512K9SA00: 50°C

(I set "$ hdparm -B 255 /dev/sda" to turn off APM immediately, after I checked my Load_Cycle_Count which was 230000+*horrible!*)
GPU :: nVidia Geforce 8600M GT ::

nvidia-settings -q GPUCoreTemp | grep Attrib 
  Attribute 'GPUCoreTemp' (D.:0.0): 69.

Running:firefox with about 20+ tabs opened but none loading anyway ; several urxvt along with ncmpcpp in screen ; WM: Musca.

What about your temperatures? post it !;)
I especially worry about the HDD temp, since it is DATA. I hear it is dangerous to stay 50+C...
It'd be rather a pleasure if the CPU temp could get down to ~40...then I'd be satisfied

Unless you're in the middle of the Sahara, your HDD temp is almost bonkers and pretty close to the limit in most cases (55C). You definitely might want to invest in a decent cooling pad. For a more "temporary" solution, try stacking up a couple of books on either side to create airflow underneath the laptop.

How old is your laptop? It's possible that the thermal paste on the CPU has just worn out or disappeared. Download a service manual from the ASUS web site (or google around) and follow the instructions to remove the heat sink. Apply a tiny amount of good quality thermal grease like Arctic Silver 5 or Tuniq TX2 for about $5 (Newegg stocks them) after cleaning the surface of the heatspreader die and heatsink with rubbing alcohol. Doing this made the temperatures in my T42 drop by almost 5 degrees.

While you're at it, use an airblower to remove all the dust that might be blocking the path of heatflow.

The Core2Duo T9400 @ 2.5Ghz in my Thinkpad T400 idles at 35C. The Pentium-M 1.8Ghz in my 4 year old Thinkpad T42 idles at 43C. The HDDs fluctuate between 38 and 45 depending on the load.

Edit:
That GPU is running quite hot as well although it shouldn't be a major concern.

Those seem quite normal to me ....
My previous laptop/notebook was an ASUS A6K and those are quite normal temperatures (during summer at least).
For the cpu and gpu I would get similar temperatures as you have (during summer or winter), even when reducing and keeping the speeds to a minimum.

The HD temperature would only get close to 50C when under heavy load or during summer (this with windoze, at the time that was I was using as primary OS and I hadn't discovered how to monitor that within ubuntu at the time).
A HD temperature of 50+ would be a warning sign that I should back of a bit a let it work slower, you need to check the datasheet of your HD and see what is the maximum working temperature for your HD and then try not to get past it (you can but it's not recommended). Pay special attention to the absolute maximum rating that should be the final limit, if you go ever it bye bye HD (or it will loose a lot of performance and data loss may occur).

A friend of mine bought an asus notebook after I did and he said that his got even hotter than mine .... so it may be a design problem and not exactly a software configuration problem ... my notebook lasted for 3 years without any major problems, the HD temperature would always be between 40C and 50C and I've never experienced any problems, the notebook suddenly died and the HD is still working in an external box and it would work around 12 hours a day for 3 years .... may be I was just lucky.

Try to check other forums and see if anyone else complains about overheating problems, you may not be alone on this one.

As for the HD temperature I would try to set the Advanced Power Management to 128 and the acoustic management to 128, this will slow your HD while not making it stop with small periods of inactivity, this should help it run a little bit cooler, don't expect major improvements though.

Thanks guys, My HD is hot. really!

I'll do some cooling, absolutely.

Dead Asus A6K, New Packard Bell Easynote MX61 (gets too hot hmm )

lol

R00KIE · 2009-05-11 12:54:55

Yeah, it has good cpu and hard disk cooling, better than the Asus but during the summer my fingers are going to get burned I'm sure. Another con just in case you are wondering is the keyboard (apart from getting quite hot) it is a full size one, not a "traditional" notebook keyboard .... I find it to be less comfortable to work with than a "traditional" notebook keyboard

lolilolicon · 2009-05-12 20:21:20

It looks cool, tough it's hot :-p
15.4 inch, that's a big one, and the keyboard looks just like a desktop keyboard. Just get used to the layout, it's fine.

CPU shouldn't go further then 60ºC... consider 55ºC as HOT and 70ºC as melting down... (pentium M can reach 100ºC... but others can't)
GPU normal themperatures are bettween 50 and 70ºC.... 90ºC is the maximum recomended level, but they can reach 140ºC without causing problems.
HDD must be always below 50ºC

Every laptop that i've fixed (cleaned) has 10 to 30ºC less more heat.(dust blocks air out). CPU 30-45ºC max, hdd 30-40ºC, gpu 60ºC its the normal values that I see.

I've opened several laptops because of thermal issues... the problems are almost always the same: DUST! Open your laptop, remove the fan, clean everything on it, replace thermal conpound and you are done for 1 more year.

Some laptops are hot by (bad) design. Temperatures don't matter though as long as you don't get system lockups or errors in stability/stress tests. The CPU and the Hard Disk are very resistant and it is very unlikely to completely break/fail because of temps.

Especially for Hard Disks, better cooling imo is completely useless, it doesn't increase stability or lifetime.

Your GPU though is a problem
The whole line of NVIDIA Mobility 8xxx series (and also Quadro NVS 1xx I think they are the same) is considered the worst quality of mobile graphics cards in history with very high percentage of failures. If you didn't had that card, I would have suggested to ignore the temps (or just clean the laptop from dust), but high temps on the NVIDIA 8xxx is the road to a dead laptop.

Search for some laptop cooling solutions, because that graphics card line has a usual 1-2 years lifetime. It would also help if you could underclock.

kumyco · 2009-05-13 09:56:56

you might wanna make sure the air flow is clean, i.e no dust, etc.
i've had my laptop for close to 2 years, and always thought the heating problem was normal
the a week ago i had to start capping it at 800mhz, finally checked out the air vent or whatever it's called
and it was full op dust blocking the air flow, just blew it out and i hardly hear the fan anymore even with cpu at 1.6ghz it doesn't go above 65C for hours un-end

thunderogg · 2009-05-13 10:02:36

You could try something I did to lower temperature of my harddisk. It might not work for your Hitachi, but it works fine for my Seagate. It lowered the operating temperature from 54C to 49C. The only thing I did was to change "hdparm -B 255 /dev/sda" to "hdparm -B 200 /dev/sda". It's sounds like magic, but it works for me. Give it a try. There is a post somewhere in this forum about it, but I don't think people took it seriously.

Lol, my laptop cpu reaches 80+ during a kernel compile... stupid POS.

LoL, if i'm using windows i have ~ 40-45C
using archlinux i'm getting 60C with pure console and 75+ in kde+running music player. coolers are mad.
sometimes i'm thinking that my laptop will fly away from me

Guys, any suggestions?
Thanks!

PS. Asus M51se. Core 2 duo T5750

That sounds like you need to use cpufreq Did you set that up?

Edit:
corrected a typo

SShin0bi · 2009-05-21 19:36:33

i don't think i need to use it, cause my hardware is fine and it don't requires to set freq lower or upper
btw, using SUSE i didn't have such problems.
is there anything that i missed?
Thanks in advance

R00KIE · 2009-05-21 19:42:47

You either choose to keep you laptop running at frying pan temperatures or you choose to use cpufreq to automatically lower the speed of your cpu when there isn't any load and consequently lower the temperature and raise the cpu speed again when needed.

As for suse it automagically configures cpufreq related stuff for you.
