Normal temps on a Pentium 4 2.8E (1MB L2, H.T. & 800FSB)

[grss1982]

First of all specs:
P4 2.8E
Intel 865GBF Mobo
512mb DDR400 (2x256)
32mb TNT2 M64
60gb Maxtor HDD
ATX Case with 2 Fans0 (1 front & 1 rear)
Enermax (Dual Fan) 350W PSU

My question:

Under Intel's Active Monitor thingy I get a 62 C on the Processor Temp with nothing running!!! :-o

Is that normal for this processor? OR is my cooling setup inadequete?

Any help is deeply appreciated.

THANKS. :mrgreen:

Is that with a stock heatsink and fan? Sound kinds of hot. You may want to check it with another method in case the sensor is wrong. I just put a new fancy heatsink on my new pc and it really made a difference. Also used Arctic Ceramic heat sink compound.

Yep, its stock.

Although it quite different from the stock fans of earlier p4's since the one I have now has a copper base?

Bottom Part of my heatsink is similar to this:

I just checked my readings on my other pc. Intel board that I just pulled a Celeron 2.4 P4 out and replaced with a Prescott 3.0 P4 and luckily I jotted down before temps (at idle I think) and here is what I got:

Processor zone:
Before: 46c-114f
After: 61c-141f

Zone 1:
Before: 37c-98f
After: 41c-105f

Zone 2:
Before:39c-104f
After: 45c-113f

So I guess I better get another Zalman 9500LED cooler as that thing keeps my Core 2 Duo at room temp! I guess the Celeron ran pretty cool after all. No wonder its hot in here

@dungbeetle:

AMAZING!!!

That's the same reading I was geting as well.

So is my setup in danger of getting roasted? IIRC, Before this the onlly high temp i've ever seen from a rig was 52c on my Sempron 2500+/ECS N2U400A Combo and that was at FULL LOAD!!!

Re: Normal temps on a Pentium 4 2.8E (1MB L2, H.T. & 800FSB)

I don't think you have to worry but I would definitely invest in a good heatsink-cooling option like a Zalman from NewEgg. I got those readings from my bios and now I just installed the Intel Active Monitor (latest version) and my processor is running at 54c. I think I read the Prescotts run hot and the max range is around 70c so that said, I would still get some better cooling The Zalman 9500LED on my other system is most excellent.
Added: Its also 88 degrees fahrenheit in my room right now. Time to turn on the AC!

Re: Normal temps on a Pentium 4 2.8E (1MB L2, H.T. & 800FSB)

Just a followup with my AC turned on in my room to 78 degrees. My current readings are:

48 Processor (about the same as before proccessor change 1 degree hotter)
33 Zone 1 (much better 4 degrees cooler)
38 Zone 2 (1 degree cooler)

which is almost back to my Celeron temps. Ambient temperature is an important part of the equation My Core 2 Duo runs at about room temp And you have to remember the fan speed is controlled by the motherboard for the cpu so those reading can and will change.

Prescotts run very hot, hence the earned nickname of Preshotts.
IMHO, I've not had or seen satisfactory performance from Cu/Al sandwiched heatsinks.
Improvement is only marginal. Go with an all Cu heatsink.

I did, did'nt do much. The all Cu heatsink was a TT Volcano 7+, IIRC.

Re: Normal temps on a Pentium 4 2.8E (1MB L2, H.T. & 800FSB)

that prescott CPU is actually running at average temp. mine runs about that too (maybe 75% that with a gigabyte rocket cpu cooler). my brother's Prescott also runs at that hot. But with those cooling devices you shouldn't worry, unless you live in a humid and hot area like southeast asia.

Uhmmm....

Yeah I do live in Southeast Asia.

The Philippines to be exact.

Anyways are saying that 57c to 60c temp when your first log in to windows XP is normal, and that 66c to 67c at full load is normal for the prescotts?

My Presler doesn't run THAT hot :o

Re: Normal temps on a Pentium 4 2.8E (1MB L2, H.T. & 800FSB)

Uhmm...

I just realized that i might have been quite a n00b when applying the paste to the processor.

Reading through the net i found out something about a rice grain or BB size blob of Thermal paste to be applied on the center of the IHS of the P4 proc.

I actually applied something like 4 times the size of 1 rice grain.

Well do another re-apply tonite, and see what happens. :-)

Re: Normal temps on a Pentium 4 2.8E (1MB L2, H.T. & 800FSB)

Arctic Silver Ceramic is what I use and you are correct, the size of a grain of uncooked rice or 1/2 of a bb is all you need. For more detailed instructions look here:

@dungbeetle:

uhmm...

Cpu-z if it helps:


Just curiuos why is it running at 1.7v????

don't this this run like 1.4v or something?

A bios check though revealed taht its was running rought 1.4v to 1.3v.

Incidentally when I checked the bios, the proc is identified as a 2.8 "C" not a 2.8 "E."

Bios upgrade perhaps?

Re: Normal temps on a Pentium 4 2.8E (1MB L2, H.T. & 800FSB)

If you go to Intels site and select your motherboard you should be able to see if it will run that processor and if so, sometimes its a BIOS upgrade to fully support it. I had to look at the serial number on a white sticker to verify mine would run the 3.0 Prescott. Definitely check for a BIOS update.

I just ran CPU_z and mine is running at 0.800 volts there. Are you running the default settings on your BIOS?

Yes I am.

Also I did the "rice grain or BB size" thermal paste application and temps have dropped to 58c at startup down from 60c.

0.800 volts? O_o I guess CPU-Z really isn't that accurate when it comes to voltages, huh?

[dungbeetle]

Re: Normal temps on a Pentium 4 2.8E (1MB L2, H.T. & 800FSB)

CPU-Z isn't very good. I deleted it already I checked my reading in my BIOS and they are as follows:

+1.5V in: 1.467V
Vccp: 1.329V
+3.3V in: 3.327V
+5V in: 5.236V
+12V in: 11.937V

I was in the middle of e-baying so I just posted what CPU-Z showed Now I had a minute to reboot... It seems like CPU-Z may conflict with the Intel Active Monitor too.
Hope that helps, I am running a D865PERL with a Prescott 3.0 proc.

Re: Normal temps on a Pentium 4 2.8E (1MB L2, H.T. & 800FSB)

@dungbeetle: Thanks for the data.

Anyways, just wondering which one is actually the vocre?

"Vccp" or +"1.5V in"?

Thats exactly the same reading arrangement I have with the 865GBF, but i'm still confused which on is processor vcore?

Anyways, I'm gonna do another re-seat of the heatsink once again, but I will try to use a different thermal paste.

maybe that would help. I HOPE!!!

Re: Normal temps on a Pentium 4 2.8E (1MB L2, H.T. & 800FSB)

Vccp is the power supply voltage for the processor core.
