oops sorry - obviously you have done it before. 2:45 AM here and I'm as sharp as a bag of hammers right now.

Without love, breath is just a clock ... ticking.
Equilibrium

Even with overclocking the temp. of this Pro.

runs at only 30'C

What is the ambient temperature?

Ambient temp. is on average.26'C

Ambient temp. is on average.26'C

Then i'd suggest that the temperature readings for the CPU are incorrect (not unusual).
A CPU at idle even with water cooling would struggle to be only 4°C above ambient, let alone one running at full load.

And to stop it alarming has been upgraded to a Zalman heatpipe with 120mm fan, but it still runs close to 70C in mid summer, in north UK not hottest place in the world.

Assuming there isn't excessive heatsink compund, the heatsink has been fitted correctly, the CPU fan is blowing not sucking etc, etc i'd suggest the problem is with the BOIS.
One of my previous motherboards used to show the CPU around the 68°C mark, after updating the BIOS (for a different problem) the temperature readings came back down to the high 50s.

At the moment cannot see the reason for 64 bit cpu's, there is very, very little software yet, even in the games market. And some of the 64 bit s/ware actually runs slower than 32bit version. Next year it may be different.

On the desktop maybe, but for serious number crunching & database work there is 64bit software out there & it makes a significant difference in performance, for the better.

Have recently upgraded to the latest BIOS release, this has made no difference to the temp. reading. If anything the temp.actually went up 1-2 'C and I wasn't dully concerned about that!

You can only get a pretty close reading, as the accuracy of it depends on the programming in the BIOS.
I'm pretty sure all x86 CPUs these days have in internal temperature sensor, if it gets above a certain point speed throttling occurs (Intel) or the CPU shuts down (AMD).
Previously it used to just be a sensor on the motherboard touching the bottom of the CPU- much, much less accurate.


Updating yor BIOS may give a more accurate reading, but if the system is running OK, i wouldn't worry about it.



Edit- fixed up yet more typos.

I wasn't worrying about it! I was otherwise quite impressed by how cool it ran.

Is it possible (of course anythings possible) that EasyTune4 is missreading the temp. values?

@ Jim : No worries, good information on that site you recommended BTW.

One of my previous motherboards used to show the CPU around the 68°C mark, after updating the BIOS (for a different problem) the temperature readings came back down to the high 50s.

@ Grant (SSSF) : I noticed that after updating the BIOS in mine it had the opposite result, temp readings increased. Prior to that it was reporting 42C to 47 under load. So I guess they are not always accurate.

GA-K8NSC-939 + Athlon 64 3500+ + 1GB DDR400

Air Cooled - akasa EVO33

Default settings
Bus Speed - 210Mhz
Pro. Speed - 2200Mhz

OverClock
Bus Speed - 235MHz
Pro. Speed - 2584.59MHz
Pro. running @ 1-2%
Temp - Idle - 25'C
Pro. running - Full Load - 30'C

Even with overclocking the temp. of this Pro.

runs at only 30'C.

@ Lord Tedric : Those are very good operating temps indeed.

I have seen my XP's run warmer than that readily under full load your are doing fine there.

With the full load that Seti places (ie your CPU never goes idle) I've seen XP's run into the 50's readily.

@ BarryAZ : Appreciate the feedback

Those temps are good - assuming that they are true readings.
For many reasons discussed elewhere on the net, these 'absolute' readings are to say the least not absolute.

I find that better indication of heat handling are (a) the temp difference between idle and loaded and (b) is the rise-fall time when going from idle to full load and back to idle. Going off load, the temp should drop back quickly to the idle temp.

@MikeSW17 : So noted, did not even occur to me to see the differences between idle and loaded.

Thanks for the feedback.

Ni newly returned, not newly knighted! Ni

Then is it possible to obtain an accurate reading and how?

Only with a great amount of difficulty. About the best I can offer is look for one of those infrared, remote temperature meters, as you're in UK you can get them from Maplin, Infrared thermometer They also have special offer on Mains measurement plugs at £12.49, see home page special offers.

You should see temps on any of the P4's that are Prescott based....ouch they are like ovens.

Prescotts are a real pain. The one I'm using right now (3.0GHz, not oc'd) is crunching only SETI (2 wu's at once) at a cpu temp of 57C full load. To keep it that 'cool' it has an extra case fan and a Zalman 7000Cu.

I don't believe actual temps above 75C... There must be something wrong, one way or the other.

I'm with Speedy67 & friends- the Pentium M, with adequate cooling, shouldn't get nearly that hot. The maximum thermal dissapation for any Pentium M CPU is less than 30W. So if something that produces 30W of heat was to reach 75 degrees C there'd have to be something wrong IMHO.
Either a cooling problem (but as it's still running OK that's pretty unlikely) or the BIOS just isn't giving the correct readings.

Having said that, i just looked up the specs for the CPUs & all of Intels Mobile CPUs are rated for 100 degrees c Case temperature.

However they only give you the temperature of what you're looking at- eg the heatsink. The core temperature of the CPU can be much higher- especially if the heatsink hasn't been fitted correctly.

So when they retire from crunching, they can get jobs in coffee makers, boiling the water... great...

I have an AMD XP 3000+ and it runs (min load) arround 48.5 deg C

but when it is punding out some of my engineering simulatiosn i have hit 75 deg C, the only reason that i haven't gone above 75 is because i have a safe guard in plance where if the temp gets jumps to 75.1 deg C the computer shuts down and restarts
