Here's a link for an online power comsumption calculator. It's quite good.

If all else fails, this will work.

I just have to visit every CPU that fits, and find the one with the lowest "recommended" power supply rating.

I was hoping to just find a table that gives the raw numbers....

Thanks -- Ned

I'm running the stock fan and heatsink that came with my boxed 3.06Ghz Prescott and your temps are the same as mine. I've had no problems as long as I keep the heatsink free of dust. I have run SETI and Flight sim and TV all at the same time with no problem as the fans just max out at 153 degrees F and CPU stays at that temp. With just SETI running 145 to 148 degrees (F). Idle it runs ~127 deg. (F).

I also use the stock fan and heatsink. Glad to hear this temp is normal then. ;)
Now I overclocked it 10% just to fool around and it runs at 64ºC (3.30 Ghz).

A Prescott is just barely getting warmed up at 62°C... I think your temps are fine. Mine goes as high as 63°C on a hot day and I've not had a single hiccup in the year and a half I've been running BOINC on it 24/7. In fact it almost seems to prefer the higher temps, although that could just be my imagination :)
That Prescott would throttle itself back before it got damaged anyway.
I use stock cooling only, but got annoyed at the fans kicking on hi/lo all the time so I downloaded SpeedFan. It has allowed me to set my fans to run at a more constant speed all the time and that's been keeping my temps much more even. I think it saves wear and tear on the fans as well. They still kick into high gear if the temps go above the threshhold I set but it happens infrequently, not every couple minutes like it used to. It's a great program if you know a little bit about what you are doing.

Yeah they are quite the hotties, heh.
I believe the "danger" threshold is 75ºC for the Prescott 630. Although I'm not 100% sure, and I can't find the temperature and power tables at the Intel site.
I'll check out that prog., Speedfan. Thanks!

Hi Scott,

I use the Processor Spec Finder at the Intel site to look up information on my Prescott. The thermal specification is listed on the first page that comes up, and if you need additional info you can download all the datasheets for your processor as well. I have my system setup to kick the fans up to maximum if the cpu temp goes above 63°C and the alarm sounds if it hits 70°C. Haven't had any problems and it's well burned-in by now. Your specs may be way different than mine though.

Ned, that link may lead to the information you are looking for as well, but I haven't checked that aspect of it.

Hehe, It was me who said that. I guess my double quote was confusing.
Thanks for the link, I've checked it out and bookmark'ed it. Apparently the "temperature specification" for my Prescott 630 is 67.7 C. Is that supposed to be the safety threshold?

When you say you have your "system set up" you mean using SpeedFan together with another external program?

According to Intel:

"Thermal Specification: (Also referred to as Thermal Temp) The Thermal Specification is the temperature at the critical point on the die and usually represents the hottest point on the processor. Therefore, the Thermal Specification represents the maximum temperature for reliable operation of the processor."

So yes, I would regard that number as your safety threshold. I've heard from many Prescott owners who say they've seen much higher temps than that without the cpu throttling back or behaving erratically, but I would play it safe and stick to the Intel number.

Regarding my system setup, I've only used SpeedFan but there are probably similar programs out there. I have the maximum 'desired' temperature for my CPU set at 63°C at which point all the fans kick up to maximum and cool everything down. Then I have my 'warning' temperature set to 70°C at which point SpeedFan will sound an audible alarm and execute a system shutdown. That's never happened though.

It's a handy utility if you are careful with it and put some thought into what you are doing. It seems to be very popular with overclockers although I am not one myself.

Yep, I've downloaded it and installed it. Checking it out now.

I wonder what is the maximun RPM the stock CPU fan is capable of achieving.
Hmm..

Regards and thanks again.

Hi Scott,

I suppose the quickest practical way would be to bump it up to 100% for a few seconds in SpeedFan and note the RPM. You could also get the model number off the fan itself and look it up, but where is the fun in that? :-)

I simply watched SpeedFan for a few days, averaged out the hi/lo's for each fan, and then set each fan to run at it's average speed all the time. My machine is slightly more noisy that it would be in low-rpm mode, but much much quieter than it was when it was constantly shifting from 700 to 5000 rpm every few minutes. That was driving me buggy.

One last thing I need to do to improve my system's cooling is a little re-arranging of the drive bays. HP mounted my hard drive vertically, right smack dab in front of the air intake slots. It keeps my drive nice and chilly but seriously impedes the overall air flow. Not sure why they mounted it that way when there are two empty drive bays up top. I think I'll see at least a few degrees drop in system temps by moving it.

Have fun,

Heh, precisely, and that's what I did. The max RPM I saw it achieve was 2500.
I used Speedfan and it's good, but after using it for a while I decided to configure and use my MB's Q-fan control, and use the Asus Probe program. It's an Asus P5GDC Deluxe mb.
It works well, and it's pretty configurable. I've decided to stick with that. ;)

Yes you are right about that. In my case I put together my box from scratch, part by part, so I arranged things nicely and the way I wanted from the beginning. ;)

On last thing: Why do you keep calling me Scott? :p

Ooops!

Do you know... I have NO idea why I've been doing that? LOL. That's pretty scary actually. There must have been someone named Scott I was posting to recently and just kept quoting that name. Sorry about that! I hope this doesn't mean I have officially lost my mind now. I really was trying to hang onto it as long as I could.

Lol. I believe it started happening after you replied to the user Scott in this same thread.
Or maybe it was all the talk about Prescotts.

If we went by the common standard, I'm guessing all of us would be tagged as clinically insane. So don't worry, at least you're not alone.
