are these northwood temps correct?

[EdipisReks]

i just replaced the intel stock cooling plus arctic alumina that i was using on my processor (1.6a@2.32 with 1.55 volts) with an AVC sunflower and arctic silver3. the temps with the sunflower are exactly the same as they were with stock cooling. i understand that arctic silver has a curing process, but i was really expecting a reduction in temps. my ambient case temp is about 28-30*c, the idle is 40-42* and the load is 52-54*c. these temps are with motherboard monitor 5, and sisoft and the bios both give the same temps. my motherboard is an EPoX EP-4BDA. i know that some pentium IV boards don't report temps correctly, but i haven't heard about that problem with the EPoX board. if someone could shed some light on this i would really appreciate it.

those temps do not seem incorrect...

comparison:

p4 1.8@2.25ghz at 1.55v....36-38c idle 45-47c load system 25-27c...avc sunflower

p4 1.8@2.4ghz at 1.65v....38-39c idle 50-51c load stsem 25-27c...avc sunflower

my system/ambient temps are better which could be better case airflow and cooling for me or just a cooler room temp...generally 73f or 22.7c

Most do not notice a huge idle difference when switching to avc sunflower...the stock is usually more then sufficient in this range...you were using AS paste anyways so you should have seen darn near 0c-1c difference at idle...where you potentially should have seen the difference is at full load where the 1300+ more rpm of the fan should help dissiapte heat better off of the fins of the HSF...maybe a 3-4c max difference there....

you could also look at making sure you cleaned the surface well of any old AS paste and didn't apply to thick of a layer....

i had cleaned the processor with 99% acetone which completely dissolved the arctic alumina, and i cleaned up any residue with 91% isoprobyl alcohol. i suspected that i had put too much as3, but when i cleaned it off and made sure that i had only put a thin smear (my processor is lapped, so it doesn't require much paste) my temps didn't change at all. i didn't expect much of a drop at idle, but the complete lack of change at load was weird. well, maybe i'll just get the alpha heatsink when i get new ram. it's not like my temps are bad for the speed i'm running, but i know that my processor can run at over 2.6 gHz, and i don't think the sunflower will be able to handle those speeds once i get ram that doesn't hold me back.

I think i read somewhere that one of the epox boards temps shows some sort of average, but isnt right. The guy was saying it didnt change when he overclocked it or at stock speeds. Kinda what your seeing.

I would look for a bios update.

yeah, i think that might be right. i just went to 2.48 with 1.7 volts, and my temps aren't any different than they were at 2.32 with 1.55 volts. hmmmmm maybe i'll mosey on down to the EPoX website.

thanks!
