I just downloaded Coretemp and Speedfan out of interest to see what sort of readings my laptop gives off when crunching SETI.
I was "blown back" in a sense to see that Core0 was 64C and Core1 was 66C! Both Speedfan and Coretemp gave near same readings... is that high for a laptop in general?

It is not overclocked and has no cooler... the one advantage my laptop has is that the battery at the back of the unit is "raised" to let air circulate freely to the fan.

Any suggestions, comments, ideas?

Sounds higher to me than I'd want my laptop to be. For a start, depending on how long you've had it, might be time to open it up and clean it out, if that's an option.

Hi, Luke.

What CPU has your Dell got? It does seem high, but I'm pretty sure that it is within spec. The problem is that laptops with the reduced airflow do tend to run hotter. I know you've been running this one for a while, so if it isn't failing at all, and you keep the dust bunnies out, I see no reason for it failing. I'm sure the guys and gals round here will be chipping in with their ideas as well (as soon as they wake up, lol!)

Hi Luke, I have a HP with a T2400 (1.83GHz), crunching 24/7 and has temps off 60 and 58, since it has very little cooling,I make sure that there's enough airflow under the LT, the fan is also on the bottom.
I run an opti-app for MB, AK_V8_winx86_SSE3.
About 60C is still safe, my OC'ed Q6600 ran a week @ 82,81,81,80, onetime even 88C, but shut's down :(, switched stock cooler with a ThermalRight120, temps are now in the 60's.
The only thing I blew was a stick off DDR2 RAM, it couldn't stand 102C, even burnt my finger.
Can't find much info on the T5800 CPU (?)

Hi

I just bought a new Dell XPS M1530 Laptop last week and was interested to see the temps. Mine is the Intel(R) Core(TM)2 Duo CPU T7250 @ 2.00GHz and has been running S@H for the last 18 hours

Core 0=58C
Core 1=60C

A little lower but it will only be a week old on tomorrow!

OK thanks for all the replies so fa from all of you!

I purchased it roughly 6 months ago, it is running on a Core 2 Duo T9300 2.5Ghz CPU...

Would it be a dust problem?

- Luke.

The host shows a T9300 CPU, and the specs from Intel list Thermal Specification: 105°C so temperatures near 65°C are not terribly high. But if the fan is running at high speed to maintain that temperature its life may be shortened, and replacing a fan is at the very least a nuisance. Ensuring minimal hindrance to airflow, internal as well as external, is obviously sensible for any laptop being run near 100% capacity. I like undervolting as a way to inprove the situation at the source, it reduces the heat produced by the CPU and reduces power usage.

                                                                  Joe

Related to this, I just downloaded Notebook Hardware Control. I turned down my voltage from 1.225 to 1.18, it did cool down to 61 fom 64 or so it had been running. The program says to be careful how low you set the voltage. How low is too low? Or do you just have to try to lower i until the system becomes unstable?

Processor: 2 GenuineIntel Intel(R) Core(TM)2 CPU T5500 @ 1.66GHz [x86 Family 6 Model 15 Stepping 6]

Yep, like overclocking you're finding out how much your processor differs from the worst case for which the manufacturer's specs are given.

                                                                Joe

i run my laptop 24/7 and it has core 2 T 5500, and temperatures are 63 celsius, so your temperature are quite similar, on hot day mine will go 67, and to keep bottom
up from tablecloth, i have two 30 cm woodsticks about 1,5 cm diameter and the laptop sits on them, no other cooling.

Yep- Mine were running arund 64-67 generally- worse on hotter days when I usually just turned BOINC off to cool it. Now I have "notebook hardware control" which allows you to turn down the voltage to processors. I am trying 1.00 volts at this point, and have the temps donw to 55. So far it seems stable too- knock on wood. . .

Just be careful that you don't reduce the voltage too much, because I'm not sure what the recovery options are if you reduce it so much that it won't boot. Us 'big' computer people have a CMOS reset jumper or switch, but I've never seen one on a laptop.

That doesn't mean to say that it's not there tho!

Obviously the bios options are limited because they don't want people mucking about too much, they try to make you use the stock options. And if you reduce it too much, you might not be able to boot into windows to bump it up again if it becomes unstable.

Good Luck! (Sorry Luke, if we've hijacked your thread! Just hope all the information will come in useful!)

I'm not sure about the software already listed, but I use RMClock to undervolt the CPU which uses software methods to change the voltage. This means that on reboot the voltage settings are cleared, unless you have RMClock run on startup. In that case one should be able to boot into safe mode to prevent startup programs from running and change the RMClock settings from there.

Notebook Hardware Control re-sets when you reboot also, so you have to run program before it sets the voltage. And since it does not start automatically when Windows boots, it will not run unless you want it to. I do not think I will go lower. The fan is barely running now and a ten degree drop is all I was trying for.

i will try notebook etc when they release updated version, vista in mind

NHC 2 pre-release 06 does list Vista support. I have Vista, and I am currently using it. Certain items do no work, but the CPU voltage settings do.
