W2V gets too hot

Hi,

I was just playing Titan Quest (a game) when my Asus W2V shut down instantly (i.e. complete power off without warning). After rebooting I saw that Notebookhardware control denoted over 70 degrees Celcius CPU temperature. So I started gaming again while monitoring the CPU temperature and it went up to 80 to 90 degrees! So this explained the sudden shutdown (which is set at 95 degrees Celcius!). After lifting the back of the notebook a bit and aiming a large fan on it (so air can blow underneath), CPU temperature remainded stable at around 70 degrees during gameplay.
This doesn't sound right does it? I knew it ran hot during intensive use, but I never had an emergency shutdown. I have to say that is was quite hot here in the Netherlands the last days, so current ambient temperature is around 25 degrees inside, but this shouldn't be a problem... Should I call Asus about this or is this normal? The CPU is a P-M 770 (2,13 GHz).

 

If all else fails, would spending your money in a cooling fan be ok (mounted underneath the notebook)?

 

do you have speed fan running. if so do not use it thats the problem. but 90 degresss is not normal for that machine.

 

Check to see if something is blocking the vents or if a fan has failed.

If it just shutdown on you for no reason, and you are SURE that it's overheating then send it back to where you got it from.

They'll fix her up, but be sure to include a letter or something with a list of problems and be specific.

My experiences with Asus techs so far here in Toronto hasn't been too great.

 

No I don't have speedfan or anything running (and the fan control in NHC is not compatible or something), so no tampering with the fans. The fan was also running at full speed so I don't think it's blocked. Furthermore, I have undervolted the CPU to 1.132V on 2133MHz, which runs stable ever since I got this notebook. I do know that it never got this hot before (90 degrees is really insane) and I don't think that the 5 degress difference in ambient temperature should be a problem (normally it's around 20 degrees Celcius inside)...

Well I'll see if it happens again and if so I'll contact Asus about it.

 

send it in for repair now. thats not normal. it has to be a faulty fan or temp sensor controlling the fan.

 

Could it also be that his BIOS is not updated?

 

No because it was working fine with your first got it. i had the first batch of w2vs that hit the US. i did not ever get temps like that. 90 should be very hard to reach. i never got that even when running 3dmarks on full speed with the w2v sitting on a bed.

 

Another update, I tested some more. I took off the lid above the cpu and fan to check if the fan runned properly, this was the case and I removed a little bit of dust. After placing the lid back I tried a 3D mark 2005 run to check whether it was not a problem with the game (which doubted), results were the same, after completion, the cpu temperature was no less than 85 degrees Celcius!
Prime95 torture test also resulted in a temperature of 82 to 83 degrees, measured by Notebookhardware control and Mobilemeter. I think I'll call Asus tomorrow...

 

what is the ambient room temp where you are?

 

24 degrees Celcius...

btw: in idle state the cpu temperature is now around 62 degrees, I remember that it was around 43 degrees before...

 

I wonder how often temp sensors give false readings. Does the vented air coming out feel dramatically warmer than other laptops you've had in the past?

 

I've had an Asus M6800 before this one, but it's hard to compare, the air coming out my current laptop is always hot under full load, but I can't tell whether it's hotter than before...
I also put my finger on the copper heatpipes (not when the laptop was on) connected to the cpu and they feel really hot, although I don't know whether I could feel the difference between 50 and 70 degrees Celcius. But even if you're right (the sensor might be broken), I still have the problem that the laptop shuts down because it 'thinks' the cpu gets too hot. Besides, even if I could disable the emergency poweroff, I don't want to take the risk that the sensors are right...

 

first of all: sorry for my english. i live in germany and i had exactly the same problem but 97C cpu overheating.

after reading this thread i removed the casing (over the cpu) to check the "dust issue". there was nearly no dust around the fan.

BUT: i removed also the 4 screws around the cpu (for the heat pipes). after removing them you can pull the pipes out very easy. now you can check the cooling rips and _they where blocked by dust_. i cleaned them and put em back.

now i am back to 60c and happy. i hope this works for you.

Quadword- You have nothing to apologize for, your English is fine

Dust (and dirt, and dander, and food crumbs, and skin particles, and eyelashes, and boogers) can cripple your notebook's cooling capabilities! Stay clean, y'all. Canned air is your friend.

Chevron, can you pull out the pipes and check for schmutz like Quadword describes? Do you have a pet or something that could contribute to a lot of particles in the air?

Probably best to check before you send it in for repair; if the repair guy opens up your machine and finds a clump of cat hair he'll think less of you.

 

Hmmz this could be the problem, I tried a vacuum cleaner on the air outlet and I have to admit it's better now (although not completely over). We do have a labrador dog in the house... I think I'll try Quadword's option, but doesn't it mean taking of the cooler of the cpu? I guess there's cooling paste or something between the point of contact of the heatpipes and the cpu? Normally you have to apply new cooling paste when you have taken of the cpu cooler, am I right?

 

Just wanted to let you know that removing the entire heatpipe and using the vacuum cleaner to clean the attached heatsink (which isn't possible without removing it entirely) worked! In idle state the cpu gets around 45 degrees (although this is slightly higher than before, probably because less optimal contact with the cpu because I didn't apply new cooling paste). Thnx for the help everyone!
