Northwood 1.8's run this cool ???

[resinboy]

Hi everyone:
running my new rig this week ( see sig below), and noticed the Asus software temp. monitor always reported 40 celsius, so I loaded MBM5, and was suprised by the following temps: 27' c idle, 36' c full load,( 1 hour of cpu burn). I realize this is a new core ( .15 core I think), and am used to my tbird 1 gig@1400, but since I am overclocking this chip as well, and have increased voltage from 1.5 to 1.7 for the overclock, I was suprised at the temps. Do these sound right?????( stock HSF, btw). Also, the idle temp is BELOW the motherboard temp sensor by 1 degree!!!

Awesome! Mine should be arriving today! Be happy, those temps are excellent....esp. for 1.70v. Seems correct to me but my rigs not up yet, lol.

btw - Northwood is 0.13µ

resin,

Yep, the new Northwood P4 processors run fairly cool....you'll need to overclock @ 2650-2700MHz to get a P4 that produces as much heat as a stock Athlon XP 2000+. That's why Intel can suffice with such a quiet heatsink...

When AMD does finally make the move to its .13um process with the release of the Thoroughbred in June, the Athlon's should see a big drop in temperatures as well.

Yes the Northwoods do run cool. 1.7 V seems dangerously high for a Northwood, I'd read up on it if I were you.

1.7V is just fine. The P4 doesn't produce much heat until you hit 1.8V...then the heat goes up dramatically.

There is no danger to the processor, because if it gets hot, the P4 will just throttle (slow down). If heat reaches critical levels, the system will shut down to protect the processor. And, of course, Intel always has that 3-year no-questions-asked return policy, should you accidentally spill lighter fluid on your mainboard while running a few benchmarks.

This is almost totally wrong. The "heat issue" is only part of the problem. Running .13um processors that far above spec can lead to gate dielectric breakdown or a permanent highly resistive path through the FET resulting in a damaged transistor(s). High enough voltages will lead to a dead chip once the breakdown voltage of the weakest FET on the chip is reached.

PM pointed this as well as other factors out in this thread

Just finish running 3dmark 2k1. Checked the temps with sandra and its at 32 C.

I don't think you're going to see much stress with 3DMark2001. It stressed the video card at least as much as the CPU. Better off downloading SETI@home or UD Cancer agent and run that for an hour or more. That will max out your temps if anything will.

All P4B266 boards read 40c, it's a bios glitch, just use MBM.

Although your temps appear to be excellent, I highly doubt they are correct. Asus temps have a history of being unreliable.
