i might switch my AthlonMP to a Northwood P4

I hope you realize that P4s run mighty hot too....even the Northwoods. The reason? Die shrinks only dramatically reduce power consumption if it allows the voltage to drop a bit, and if the frequency doesn't jump too much. Both AMD and Intel have their chips jump in frequency a LOT...
You might get better times out of the northwood though

<< That's what basements are for man!
>>how bout an apartment with the computer sitting by your head?

>>don't ruin it for me...
besides, with better times, i'll be able to tolerate it A LOT better. my 1.0ghz pally is running at 1.49ghz, 8.5x175mhz fsb, 8-8-7-2-2-2-2 ram timings, using a taisol cgk760092 and sunon 26cfm combo.
using 4 case fans, 2x80mm for intake and 2x80mm for exhaust. i tried using my 120mm panaflos, and although the fans themselves are quiet you can hear the sound of the air moving through the case.

<< Have you chopped off the fan grills on the case? I've heard they can make a lot of noise. >>
yeah, i did. not a lot of difference. the antec sx1030b is pretty well designed.
Ahhh, the quest for quietness! It is a difficult task, but can be accomplished.
First thing is that there is no reason to have 100+CFM going through your case. As long as you have a good 30-40CFM with an absence of "hot spots" then you are good to go. You probably don't need as much airflow on your heatsink either.
I've currently got my Enlight 7237 case running a good bit quieter than my roommate's Celeron 633 E*Machine(POS) after getting a tad anal about noise.
Here's what I would do.
1. Wire 2 3W rheostats in the 12V lines before each group of 80mm fans. You can just change the fan speed with a twist of the knob. This means you don't have to shell out anymore money for more fans, and the rheostats themselves are pretty cheap. I've got just 2 92mm Panaflo L1A's exhaust on my case(with a HUGE hole cut in the front for a future radiator) with a rheostat turned all the way down. My case temps are 1C over ambient and I can't even hear the fans 6" away in a silent room. The only fan I can kinda hear is my 28dB Sanyo Denki fan, and that is muffled from the sound insulation in my case.
2. I'd get a Sunon 23CFM 33dB fan for your heatsink. You'll be surprised with how much "whine" is gone but I'd suspect your temps will only go up 1-2C.
3. You could also get two even quieter 60mm fans and adapt them on your particular heatsink. Here it makes for good cooling with a total noise of less than 25-26dB possible.
I have other suggestions, but those would really make you sleep sounder at night. I'd expect your temps to rise a total of about 2-3C, but your chip can probably still run your current speed. If worse comes to worse and you experience instability, just knock the FSB down 1-2Mhz. I doubt you'd really notice much of an increase in your Seti times then.

Def - it wouldn't really work. with the stock 19cfm fan, i could only reach 171mhz fsb. the new sunon is actually quieter that the old slim delta. the chip puts out A LOT of power. i'd say that it's close to 80w.
If 171 FSB is stable then it is good if you don't have all that noise. I bet letting is run 24/7 is better overall than runnning at 175FSB if you have to turn off during your sleep hours.
actually, running at 175mhz fsb with the sunon is QUIETER than running at 171mhz fsb with the stock delta.
The slim Delta that came on the Tiasol heatsink was 19CFM @ 36dB. The 60x25 Sunon I was refering to puts out 23.5CFM @ 33dB. Quite a bit quieter and a bit more airflow.
As I said, another option is to attach two 60mm fans to the heatsink. I'd say you could get by with two 19CFM 28dB Sanyo Denki fans and easily get the same or better cooling at a lower noise level.
I really bet the majority of the noise is coming from your case fans, and you've probably got more case ventilation than you really need. While the heatload is pretty high for a single chip, 40CFM in and out should be more than enough total airflow for your needs. With 2 80mm fans putting out a combined 40CFM, expect ~20-22dB for each pair of fans. That's just barely above a whisper.
With a little bit of work, it's amazing how quiet you can make your computer if that's what you're going after.

Hey TuffGuy,
Ever think of not OCing it so high? or even trying it with a little less cooling to see how she does?
Im running my 1ghzMP@1324 with a PEP66. I dont think its my cooling stoping me from going as higher, but my CPU. Wont even post @ 1400 ....8(
Consider trying the fan on it now @7V instead of 12. Might help.
