I would like to put together a table/listing of Precott CPU temps for comparison. It's a given that these chips run alot hotter than the Northwoods but trying to find info on the "Norm" is hard to do. I think it would help alot of us Prescott users to see where we stand with our operating temps.

If everyone will post their info, I will make a table listing the responces in an easy to compare format. Please use SpeedFan or Motherboard Monitor5 to find your temps. All responses will be greatly appreciated.

Please submit the following info:

CPU type and Stepping - Prescott ONLY
CPU Rated speed
Current FSB setting
Type heatsink used
Board brand, model and chipset:
Bios Version:

Room temperature in degrees C ((farenheight - 32) / 1.8)
CPU Idle temp. in degrees C
CPU Gaming or Benchmarking temp. in degrees C
System temp. at Idle in degrees C
System temp Gaming or Benchmarking in degrees C

CPU type: Intel Pentium 4 3.4GHz 478 (Prescott)
3.4GHz
800MHz FSB
Stock Fan/Cooler
ASUS P4P800SE
i865PE
BIOS: Latest Beta
Room Temp: 25 C

CPU
Idle Temp: 36 C
Full Load: 47 C

Your numbers may be wrong. I cant see how you can use 40c air through a fan to cool a heater (any cpu acts as a heater) to 36c. It just isn't possible.

I would have to agree about the temps being swapped. Which of the programs are you using to get the info? Also what tpye of chip is reported as giving you the temp reading ( should be the same in each program)? Usually the #2 chip is the CPU.

My physics (and especially my thermodynamics) are more than a bit rusty, but if I'm not mistaken, it is possible (well, in theory). It would imply nearly supersonic airspeeds and/or pretty impressive pressures though :p

Here is a pretty useless piece of aerodynamics for you. At mach 3, most metals get so heated ( air friction) that they flex to the point of being incabable of structural use. I think that at that speed, the exterior of jets reach temps in excess of 1000c. Even below sonic speeds, air friction will cause an object in motion to heat.

It depends on which way the fan is facing! Normally I prefer the fan to blow downward due to directional flow, but in this case, having the fan blow supersonic airspeed AWAY from the core would cause a low pressure center BEHIND it...cooling the CPU!

there's little differance between the tempsof CPU and MB, I hardly doubt I switched them.

Someone asked,
I used ASUS pobe, Speed Fan, some bios for support, MBM 5, Sisoft Sandra 2004 Std. and an infrared temp probe for confirming correct MB temp. (Northbridge is passivly cooled)

I have a 2.8E Prescott

Idle: 47C
Load: 51C

When on load, my mobo increases the fan speed if needed.

A 2.8C will run idle at around 35C and around 47C under full load, with a slower fan and less effective cooler. A D0 or later stepping Prescott would also be cooler than typical Prescotts most people already own. And I'd need those moderate temperatures for overclocking.

Correct me if I'm wrong but the only 800MHz 478 prescott(according ito Intel's web site)that has a DO stepping is the 3.2E. Of coarse there is the 2.8A at 533MHz. It seems that if you want a DO stepping 800MHZ Prescott that you have to go with the 775 package.

I really miss my 2.4C with the stock fan running at 30C idle and 44C full load.
August 3, 2004 12:52:55 AM

i didnt say YOU switched them, i said that the monitoring programs did

it happens often. besides, i highly doubt your northbridge is running at 50c, but your cpu running at 50 is more realistic

Intel WILL do exactly 1 of 2 things: Either quit making the 2.8E or switch it to a newer stepping. Intel updates their entire line to a new stepping, so that the only way a 2.8E D0 or newer will never be available is if they stop making the 2.8E very soon.

CPU: Prescott C0 Stepping (Spec SL7B8)
CPU Speed: 3.2GHz
FSB: 800MHz
Heatsink: Retail Boxed
Motherboard: Intel D875PBZLK
Bios: Intel P27

Room Temperature: 23C
CPU Idle: 53C
CPU Full Load: 63C
System Temp Idle: 38C
System Temp Full Load: 43C

The three hottest components in my system are:
The ATi 9800XT video card which averages 71C.
The CPU and the 875 northbridge.

I tried using an aftermarket heatsink fan on my CPU. It made no improvement and the fan made more noise. Intel bundles a high quality heatsink fan with the Prescott.

I am currently getting my spreadsheet together and will post it soon. I have been collecting this same data from 3 different forums.

A big THANKS to everyone that has responded so far. The more replies I get, the easier it is to get a real average for the Prescott.
August 4, 2004 2:41:53 AM

Sorry about that, the program seems fine.
When I put the computer on load, temps labeled "CPU" rises much faster than the one labled "MB"
sometimes 3-4 degrees a second. MB temp rises slowly so my conclusions are that the temps are correct.

I found the fan very noisy, especially when at full load. I found a great hsf aftermarket called Zalman CNPS7000A. its pricey, but well worth it. It comes with 92mm fan 2500rpm only dB25. Very quiet , best part is the temps, it went down, only 43c idle and 65c full.

I still like to see that my full load temp is your idle temp! And that my cpu is outperforming yours in everything xept maybe DoomIII!!!
And above all mine is 1year old and considerably cheaper.
Of course I am <b>cheating</b> by overclocking it! ;-)

what were your temps before the new heatsink?

my temps on intel 3.0e stock cooler was 47.6c, 62c full. dB 41.

my temps on intel 3.2e with Zalman CNPS7000a was 43c, 65c full load. dB 15 silent mode, dB 25 in normal mode.
