Insane temps and WEIRD problem with my 9880 - Page 2

I grabbed the box the laptop shipped in and placed it on it and tilted it directly onto its right hand side (onto the dvd tray). The only place I touched it was at the base of the right side hinge on the screen and the front right corner of the laptop. The exact same thing happened.

I just tilted my 9860 from left to right lifted up the card reader side while i kept the cd drive down to an approx 50degree angle... using get thermal i was idle at 44-45, and when tilted temp climbed to 85 degrees + and did the critical shut down. Interesting, the temp (felt by hand) was not getting any hotter at all. My suspiscion is that, if the temp sending unit is like mercury based, by tilting it, may just be a false reading. But, it also happens on the 9860 as well. weird

You got a critical shut down? I think we need to hear from someone at PCTorque if this is a known issue or one that they will contact sager on.

Mercury would make sense, but do they use it in laptops... they are portable and not always on a flat surface.

yes, I did get the critical shutdown. I was getting a bit nervous watching the temp keeping increasing, but the exhaust was not even warming up at all. So, I kept letting it rise to see what it will do. The critical shut down is set at 85C and once it read that temp, it did the critical shutdown. I quickly restarted and temps back to norm. Im not sure if it is mercury or some other liquid or not, but it kinda makes sense to me. but I dont really know for sure. Oh, btw, I only noticed the cpu temp increaseing, the system and GPU temps remained fairly constant. Although the GPU actually drop a degree, probably due to better air flow being lifted up in the air like that..

I suspect it's simple gravity. Maybe when the lappy is on its side heat rises into places it's not meant to or places where the fans can't effectively cool or wisk the hot air away.... <shrug>

Thread Starter 
Where is the CPU temp sensor located? If it's on the CPU, as it most likely is, it's just an IC. In that case, it means something is either interfering with the heat pipes, which I doubt because they use capillary action, or something is causing the heatsink to come away from the CPU. Or maybe something gravity based, like a flap or something, is restricting the air flow to the CPU heatsink. There are so many possibilities :/

maybe when u do that ur actually makes it difficult for the air to come out of the unit. It gets in and gets stck somewhere inside )coz u know hotter air is less dense and rises up) and thus the hot air goes up to the left making something hotter(maybe some heat dectecting chip or smth) and this temp detecting piece gets hotter tho the system by all does not.

Just another way of seeing this problem, i have no laptop to give specific info !

Hot air rises. It's possible that hot air from the heat sink rises directly onto the sensor when at that angle. So instead of a true reading from "heat soak" from the heat sink, hot air hits the sensor showing a false reading.

It is a weird problem though...

what program are you useing to measure the GPU temp?

happens to me then I open it up to a "V" and set it on the side.

I bet he is using ATI Tray Tools... - http://www.radeon2.ru/atitray/

Id rather not risk blowing up my *desktop replacement* by doing some stupid shit like that.

Same here... I wont do that to my DTR either but i dont mind OCing it to hell and back...

NO, And ill tell you why... ATI fanboys are h8ers same thing with nvidia fanboys... the ATI's thought of it first and nvidia's dont want to have anthing like what they got...

get your facts before you talk. i haven't overclocked anything on my laptop.

Maybe they didn't put the screws in the heat-sink all the way down to avoid cracking the CPU, and they were alittle bit too cautious in doing it. Resulting in it not sitting tight enough and when you are tilting the notebook it moves the heatsink of the CPU (somewhat) and makes it every so sligtly less snugg fit with the heatspreader.

I think the temp sensor is just giving a false reading in that position. I can understand the readings climbing that fast but it comes down even fast. Its got to be false. When its on its side/angle the temp from the CPU must be radiating directly on the sensor instead of its normal path.
