Overheating GPU???? X205 Sli3

y2khardtop · 05-03-2008, 09:00 PM

Was playing Trackmania Nations last night...which always pushes my laptop to really high temps, and it just SHUT DOWN instantly to black. I removed the battery, disconnected the power, an let it sit a few minutes. It restarted fine, and has been working fine since.

I'm running XP and 169.09 drivers, but have done NO overclocking of anything. I see around 85deg C GPU temps at idle, and it hits 105deg C running the game. That seems high, but laptop GPU's are always hotter than desktop.

Any ideas if this is reasonable??? None of the other games (Bioshock, Portal, even limit Crysis) caused the machine to actually shut down.

Thanks!

Yes, your system is overheating and automatically shuts down as a precaution. 105C is quite high and should be a concern. How long have you had your x205? It might be a good time to clean the fan and grills in your laptop. You can also try downclocking your GPU to see if that solves the problem. Buying a cooling pad is another option.

I would contact toshiba and see what they have to say.
Cleaning the vents will probably help also.

The system wont shut down when your GPU temps get high, it will shut down when your CPU temps reach a certain threshhold. You should be looking at your CPU temps not GPU. Maybe since they're on the same heatsink your cpu is also getting hot.

had the computer since September, and it's always been hot, but never to the point of shutting down. Now it's just done it again.

I ran the game with Speedfan running, and the GPU gets right up to 104C, and the CPU's go up to 84C. It didn't fail while I was monitoring it, so I don't know at what point it crashes.

Anyway, my vents are clean (done regularly), and other than running XP, the chips are all running at stock speeds.

Since my CPU HOT temps are about the same as my GPU Idle temps, do you still think the CPU is causing the failure???? I know how to slow down the GPU's, but I don't know how to underclock the cpu's.

Any advice appreciated, but a Gaming PC that can't play games is pretty useless. btw, it's nice an cool in my kitchen, and the computer is sitting on clean, cool granite.

I put a little fan behind my laptop, and that knocks a good bit of temperature doewn (91gpu, 60 cpu), but that isn't very practical.

even lowering the GPU speeds to the minimum (using Nvidias control panel), I still see 85deg GPU temps, and 55C CPU temps at IDLE.

This never bothered me until it actually started shutting down. Do all Sli3's run this hot?? I'm thinking of selling it and getting a fast desktop and a portable laptop. I love the machine, but it doesn't travel well, and I have room for a desktop now that I've moved.

Now I don't have the SLI3, but I gotta say the case its built in (same as mine) is amazing at removing heat.

I'd be more than willing to bet you have lost/locked up a fan somewhere inside and that is why you get overheated.

both visible fans (from the bottom) are working, but they don't seem to vary in speed. The Nvidia control panel doesn't give me the option of changing speeds. I wonder if there is an issue with the XP drivers not being properly set to control the fans on my dual 8600 setup??????

Anybody else?? I'm thinking of restoring VISTA just to see if the temps are similar, or going to an older video driver that "officially" supports the dual video cards.

installed old 165.01 drivers, and the GPU temps are about 10deg cooler, however, they still get up to around 95 while playing the game. The fans don't seem to be any more aggressive, I think these drivers just push the cards less.
