How High Is Too High?

[DLS2008]

Well, I think I've just seen the highest temperature I've ever seen for a CPU. The Core2Extreme X9000 in my Dell XPS M1730 just hit 100C!!! I about . my pants, I couldn't believe the readings I was getting from Core Temp. It runs stock at 2.8 GHz and I decided to see what it could do at 3.0 GHz. I used the built-in overclock step from Dell. They give four CPU speed options in the BIOS and I just upped it a notch. I used to run at ~65C under load from Orthos. Once I upped it, it hit 100C under Orthos! At that point I reverted to the 2.8 GHz. I didn't think it could handle those chips. Plus CPU-z was recording like 1.415 volts to it, a little too much for my liking. Anyways, what does everyone think about this?

 

P.S. It is resting on a Cooler Master Notepal cooling pad, one of the few I could find for a 17" notebook.

Damn son! Those are some high temperaturetes, that's not safe. I would think a laptop CPU is about the same as a desktop related cpu (temperature wise).

So do the temperatures so up to 100C all the time?

Also instead of using core temp try Real Temp, it's great for 45nm processors.

I'm pretty sure laptop processors can sustain more heat than their desktop counterparts, but 100C is pretty damn hot

Inte's thermal spec on the T9300 says 105c but if I ever saw my CPU(Hell, even my GPU) get that hot, regardless of it being a desktop or laptop, my rig would be shut down without a moments hesitation. If that were my laptop, it would stay at stock. Can't imagine the performance gain between 2.5GHz and 2.8GHz being justified by the extra heat your CPU is going to be tossing at everything in the laptops tiny body...

That's pretty crazy, what are the volts set in BIOS for 2.8?

bah your fine, push it the highest it will go! just kidding, but in normal operation, even gaming you should never hit full 100% load like you will in orthose, therefore you should be ok, also did you replace the thermal pase and make sure the scfrews are all tight for the heatsink? maybe even take the bottom plate off all together and let that cooling pad directly cool the heatpipes, my laptop runs about 15-20c cooler when I do that.

1.415v on a 45nm mobile... But anyway, 1 you don't have a T9300, 2, if you read your own signature or CPUz it's the X9000 aka the extremely overpriced unlocked mobile CPU.

When I read that topic name I was like ....

OK, OP edited to reflect an error from just trying to get this up quickly. Anyways, the X9000 has a thermal spec of 105C. So it's close to the limit. The laptop was not allowed to run that hot. The instant is hit 100C was the moment my mouse clicked "Shutdown". It runs stock at 2.8 GHz with 1.313V by CPU-z. The Dell BIOS does not allow any adjustments other than selecting your clock speed, up to 3.4 GHz by 0.2 GHz increments. I just decided to give it a shot at 3.0 GHz to see what it could do. It idled at ~75C upon loading Vista. To whomever suggested opening my case, I'll pass and keep the warranty because it's about to need it anyways. So it's staying at 2.8 GHz, it's just too hot otherwise. It hits ~65C under Orthos at 2.8.

Whoops, dunno where I got T9300 from(was it in his original post because I don't remember...)

 

Either way, even though it says 105c I would personally never run it that hot. That is unless you're looking for a cheap way to sterilize yourself which, if you actually put that beast on your lap, may be a good thing to look into.

Yes, it was in the original post, it was a typo on my part from trying to do too much at once. Actually, there is no way I'd ever put this thing on my lap. I can barely touch the back of it at 2.8 GHz under load. It burns my fingers. It's running around ~60C right now under ~50% load (F@H running) It'll go up to ~65C or 70C under 100% load because the fans kick up a notch.
