Is my 3ghz notebook too hot/throttling?

OK, time to let you guy's chew on this one a little.

I've got a Sager with a 3.06ghz, a cpu that model was never sold with by anyone other than Alienware.
I believe it's running too hot.

For a long, long time, there was no way to monitor CPU temps on this little rig, till some pretty smart assembly language fellow
worked it out and now we can all see our temps. What I see, and about what other see, is high 70's to low 80's under hard use.
This is the few of us running the 3.06 and the 2.4ghz or so crowd as well.

The bios will shut this rig down at 85C, but there's a catch. It will only do this if you disable ACPI in the registry, which is necesary to use the afore mentioned
temp monitoring program. If you leave it enabled, it never shuts down, and you never know there's a problem.

So the situation is this.. I can run CPU Burn, game's, RC5, you name it, and see no noticable slowdown and it never shuts down, WITH ACPI enabled.

I can change the reg entry and disable ACPI, allowing the temp monitor to work, and do the exact same test's and it will shut down at 85C every, single time.

My conclusion is that XP has something to do with throttling the P4, otherwise it should shut down in both cases.

And yes this is a Desktop CPU in this notebook, and no the battery life isnt very good.. 🙂

The man also wrote a program to manually, on demand, throttle the P4 for increased battery life and lower heat production, that was pretty darn cool.

Anyway, thoughts? Am I right about there being some interaction between XP and the P4 via ACPI?

I'm going to downgrade to loose some heat or something at any rate, but I'd like to know anyway.

Thanks..

 
The cpu in my sig came out of a sager laptop
those things run hot

I definately couldn't sit comfortably with it on my lap for long

i think P4 notebooks produce too much heat to have ever been made anything but small form factor desktop pc's



but yeah the P4 can throttle itself when it reaches too much heat
tomshardware has a video of this happening when he took the heatsink off during Q3 game play
it prob is ACPI having something to do with it




in any event you got a pretty powerfull desktop with an lcd screen and a battery there

sorry it's so hot



if you do downgrade like your saying i would suggest keeping your eye opened towards transmeta and the nforce3
laptops based on their newest proc and nvidia's chipset sound interesting
otherwise centrino would prob be the only bet right this second for reasonably high performance at low heat dissipation




good luck
