Laptop Temperatures

[jamesriley94]

Hi,

Been using my laptop more recently and I'm a little concerned over the tempertures.

The laptop is a Toshiba P750-114, with an i7 (2630QM) with a GT540m. It has Nvidia optimus so runs on integrated graphics unless under load...

But Idle temps are around 65 degrees on the CPU - GPU doesn't really matter at idle.
Under load, the CPU and GPU are both around 98 degrees C.
This was while running Unigine.

Anything I can do about this aside from getting a desktop cooling stand or similar?
If it was possible to replace the fan inside, I probably would.

Also, does anyone know anyway to find out if the 540m is a separate card? ie - would I be able to buy something like a GT660m: http://www.ebay.co.uk/itm/GDDR5-nVi...raphics_Video_TV_Cards_TW&hash=item27cf4018ae
and replace it?
No idea how these things work for laptops

Thanks!

Could try taking it apart and putting some decent thermal paste on there? other than that one of those cooling stands would be the only other thing i can think of.

Clean the dust out of it, and then get some new thermal paste on it. Have done that whit my laptop and that worked lovely all the way

I've taken it apart, cleaned the dust out, and done a TIM change...

This was the state of the TIM when I got the heatsink off:

Little too much I think

Temps are about 15 degrees lower at idle now. I'll run unigine and see what load's like.

I do a complete cleaning job for my laptop every 6-9 months. No other way around it, and when the radiators are clogged by dust, unless you get a military grade turbo-jet under there, no laptop cooler will help.

thermal paste is shit at normal. thats because they use the cheapest and worst thermal paste ever. My laptop(Clevo W150HRM also runs hot(99c). but that is with replaced thermal paste! But i don't really care about it anymore. My GPU is onboard so i think yours is too.

Impressive results

Good job and good luck.

My Ex wife has a Toshiba (I forget the model number) and it started running hot on her. I tore into it about 3 months ago and found the same situation with the heat sink compound, maybe even more. I wiped it down and cleaned it with a 99% isopropyl alcohol. I also had to clean the fan and used a drop of graphite based super light oil on the bearing. It was dragging. We left a while for lunch and I had a small fan blow on it to be sure all the alcohol had dissipated, not hard with 99%, but I wanted to be 100% sure. Lower percentage has too much water and can cause a POOF! It ran much cooler and you could not hear the fan running. Still the same she tells me. Hope it goes as well for you.

i had the same with our toshiba satelite pro win 7 pro etc i had to change the thermalpaste.

i used artic clean to remove and replaced the tim with some ic7 diamond cleaned the gpu fan and after dropped over 15c at idle instead of being 57c idle it now runs at 41c on all cores underload it used to hit the high 90s now hits just over 75c

what i need now is to repair the laptop again is a new keyboard and motherboard as my kids managed to break all the usb inputs and lose half the keys off the keyboard but it still works lol

Sounds like a possible issue for Toshiba then. Her's is a Satellite Pro with Win Pro 7, just don't remember the exact model.

Got similar temps on my HP Elitebook 8540p. I tried changing the thermal paste and the fan but the temps went from ~90ºc to ~80ºc under max load and on idle it's something like ~45ºc. The idle temps didn't change at all and by my head, losing 10ºc are far from enough.

So I had this crazy idea that maybe I could change the internal cooler. I don't know if this is possible or I just have to stick to a clumsy and stupid laptop cooler...

You are not going to find anything to switch to. Sometimes it is hard to get original parts without buying whole assemblies that at times cost as much as a new laptop. Years ago I had an HP when they made a big step up in processing power in laptops. It was a mistake looking back, it was HOT! It was an AMD Athlon XP 3000+. After warranty I modded the case. I did the paste change. The narrow slots for air intake I cut out, covered the hole with a fiberglass widow screen material.

I also cut out the exhaust vents and the way they were I left it as is. That helped a lot with allowing free air flow. HP was absolutely no help, just said, "Those run hot, it is okay."

The step-up back then was this was the first full fledged processor, not a trimmed down processor just for laptops.

Looks like I have to get creative to get it down to an acceptable level..

Heh. My MBP is at 97*C 24/7 a day

Damn that is hot!!! But on the other hand there's nothing wrong with torturing a Macbook :lol:
