running at about 67 degrees under full load..maybe even a tad more... Too hot? Intel 3.0 hyperthreaded ,1.2 gigs pc3200 400 mhz ram, xp pro sp2 etc etc...
I'm using a stock heatsink and fan and had to apply the thermal paste myself...
I really need to know if she's running way too hot and what level would be considered dangerous...
Thanks

It does seem a tad hot, although still within tolerances (without looking it up, I seem to remember 75 being the max recommended by Intel)
I'm running a 2.6@3.38, 100% utilization all night long with 2x instances of folding, and I'm tween 54-57 right now, cuz we have the heat on for winter. Usually below 50 in the spring/summer/fall, when windows are open.
Also using stock HSF, and the thermal pad that came with it.

yeah that is very hot. If your temps are that high i would a) get some case fans b) get some artic silver 5, c) get a new heatsink.

I agree with YoSC and ub3r_n00b, that's too hot IMO. I think YoSC is right on the 75* thing but I wouldn't want to run my processor as hot as yours is getting.
With Ceramique and a CoolerMaster HSF (IHC-HC7, I think it is), I'm running 41-42* with 100% utilization on a P4 2.4C OC'd at 3.0 GHz. It sounds like a server but that's music to my ears. :D

Bummer..... I wonder if it is a thermal paste issue. I have 2 intake case fans on the front , 2 exhaust fans blowing out the rear and of course the power supply fan as well.
I'm just not convinced it's the heatsink and cpu fan but more likely the amount of thermal paste I used. I thought it was to be paper thin....I think I used just enough so the paste was almost (pretty much) transparent. It was white in color... eeesh.... I'm concerned now...
Must find tutorial on applying thermal paste...
Any tips?
BTW your input is greatly appreciated and I regard most members of speedguide very highly. It's a privelage to be a part of this community. :nod:

i think its the other way for paste.. i dont think it should be all that thin. I know for as3/5 it has to be really thin. What i usually do when i apply as3 is get a plastic bag or something, or some plastic wrap.. and wrap it around my finger.. then i put on a little dot on the core and then spread it around nice and thinly, then i rub whatever is on the plastic on the bottom of the heatsink.. but i rub it in.
Thats how i do it.

After some studying and investigating I am concluding (for now...) that the silicone based thermal paste in combination with not cleaning it as well as I probably should have is most likely the cause. I'll get some arctic silver or a similar "grease" and clean the snot outta both the contact surfaces and re-apply. Also I will most definately purchase a quality heatsink at the same time. I have put far too much money into this rig to take any chances on cooking something.
As well I have always liked the idea of water cooling but can't justify it unless I overclock the cpu...which I am hesitant to do...
I'll post back when I get a chance to do this and will let you guys know how it went.
Follow the manufacturer's instructions regarding how much to put on (I think there's a tutorial at the Arctic Silver site).
I just place a small drop, about half the size of a BB, on the center of the processor. That's it! All you want to do is even the contact patch between the processor and the heatsink by filling in the microscopic pores in the metal and evening out any irregularities on the mating surfaces. Just use a small amount! Based on your description above, you put WAY too much on and now the paste is acting as a thermal barrier! The paste will spread out over time to cover the appropriate area.
If you go to the Smithsonian you can see a sheet of gold foil, around 5 FEET by 5 FEET square that was made by simply flattening out a piece of gold the size of a BB! A little goes a LONG way.

Thanks, I'm sure I applied just a tad too much which from what I've learned (in the past 2 days) can make a big impact.... Just gotta hold out for a few more days to get the arctic silver.

Intel P4
3E GHz 800 MHz Bus - 1MB L2 Cache - PGA-478 Pkg (that's what it says on the box of the CPU)
The mobo is a 865PE Neo2-P (on the box it says "Prescott Ready") as well as Northwood/Prescott Socket 478
I have no idea if it is a Northwood or a Prescott though...Can you tell by the above description?
What's the difference?

That is a Prescott, that's part of the reason it's running a little hotter than normal because they generate more heat than Northwoods. Still sounds a little bit on the warm side though.

:nod: Im at 30 C on Idle and mabey 36-38 when Im gamin....on a regular 2.4 tho :(
Make sure you use a xylene based compund (ie brake cleaner or goof-off) to clean the heatsink as the stuff sticks in the pores in the metal. Clean the core with acetone.

I went to my local computer store to see if the had anything besides the standard silicone based thermal paste they gave me previously...they don'y though. But to seperate people in the store said running @ 70 degrees under full load is normal and nothing to worry about. Hmmm.....
My old processor, a p4 2.4c, was always running hot. i had it running at 3.1 and it hovered just under 70C. I dont think it ever ran under 55-60C, such is life.
What motherboard are you running? There are a number of motherboards that incorrectly report the temperature and the companies dont bother to fix it.
My p4 3.0c is running at 3.65 and maintains a temp in the upper 50's.

I'm not up on the temp range of Prescotts....but I do know they are substantially higher than the earlier P4s. So comparing your temps, to other P4 users like myself who have prior versions of P4s...is not the thing to do.

70 under load would be the max, and I would not allow that on my system
u can get atrctic silver online.
Did u add thermal paste on top of the pad on the heatsink or did u remove the pad?

thats good, removing it and cleaning it well and letting the thermal grease soak in and add a drop on the heatspreader on the core would be a good idea.

I didn't clean it as well as I should have. As soon as I get my hands on some good thermal grease I'll do it like I should have in the first place.

I didn't find the temp specs for the Prescott on Intels site in the couple of minutes I have right now, but a quick Google on Prescott temps (which I don't have temp ranges memorized yet), to commonly be in the mid to upper 70's (C)/170-180's (F) range, under load, with quite a few sites having it run even hotter.
The thing runs on almost 20 more watts under load than the Northwoods. I am SURE the max recommended temps for the Prescott are much higher than the 75 for the Northwood, so even less to worry about.
Here's a good read about Northwood vs. Prescott, it mentions higher temps for the Prescott core as well:

Whew....I feel better now. Thanks Guys.
Most importantly, the PR runs quite a bit hotter than the NW. This is due to the smaller manufacturing process and the strained silicon which lets more heat escape. However, the PR has a higher temperature threshold than the NW. 70C-75C(PR) compared to 55C-60C(NW). The current stock cooler is, I believe, a temporary solution taken from the NW which is why it makes the PR run hotter. however, temps like 63C are not worrying for a PR.
Be that as it may, you'd be wise to invest in an aftermarket HS/F combo that allows you to run as cool as possible. I know I would, regardless of how hot they're "supposed to run." ;)

Be assured I'm going to ASAP! See I have a little problem called "havetomakecomputerbetterallthetimeitus".
I'm just not so worried that damage is going to occur, but will without a doubt get her running as cool as possible.....and once that happens I'll need handcuffs to stop me from overclocking....

OK so I got some new thermal paste. I tried to get a good thermal grease but not one store stocked it. I bought some goof off to give the surfaces a good cleaning first and then re-applied the thermal paste. I put way more on this time as last time I didn't put on very much. I managed to get it about 5-10 degrees cooler which is good. I was seeing temps go as high as 76 degrees before and now I have yet to see it break 70.
Whew...

I thought last time you put on too much? Remember, you only need a small, BB-sized or less drop.
How long ago did you put it together?
If you did it a day or so ago, give it a couple more days...
It is a bit hot though. The problem with it running that hot as a norm, it when it gets dust in there, or your house heater is turned up too high (by accident even), etc.
I only put a thin layer, as too much will squeeze it out onto the processor, so if you do re-seat it, please do not put too much... The purpose of the paste is to eliminate any small (basically microscopic) airpockets that would be between them, thus giving as much transfer of heat as possible...

In all reviews I've read for the p4E's if your using the stock heatsink you will get better results with the thermaql pad over basic compound
The chassis temp must remain below a reference 38 Cel.
You may look at the Inter Chassi Air Guide reference sheet regarding ducting cold air directly to the processor.

I'm waiting on a new board to fire up my 3.2e and am reviewing cooling solutions now to control case temps. This appears to be critical to the big p4's

And yet the temps are lower now, but will give it another go when I get the new heatsink...

The Chassis temp is usually about 32 cel. and I can't see it going above that, or close....
I did do some research on my P4 3EGHz and I am definately not the only one concerned with the operating temps. But this Prescott does run hotter than you would expect from what I have gathered.
The hard thing about seating the heatsink on the cpu is that when the mobo is in the case you cant check to see how well it actually seats. I guess the only way is to take the mobo right out first. :cry:
Well....I will go for when Last try when I get a new heatsink...I like the one Chris recommends...looks kinda like something you'd see on a Harley Davidson.

NICE LINK! thx. I already have a flame design in the side for a case mod I'm working on and can incorporate that into it. (will plasma cut the flames at work) Metal fab shop :)
Got he 3.2E together today on the p4p800SE
Temps are ok
52 cel under full load and System at 42 cel.
This is with Hyperthreading enabled and two instances of Folding running.
Not worried about the processor at all. this is with the stock heatsink and Nanotherm (http://www.8ballshardware.com/articles/thermalpaste2/page3.cfm) XTC silver paste. But the system temp is too high for my liking.
Thinking the ducting mod may be the way to go, but I have a side blowhole right beside where the Duct would need to be but.
So I will have to think on this for a clear path for the duct.
http://nanotherm.com/
Well reversed the direction of the case side fan, have it blowing in instead of out, System temp dropped to 29 cel, CPU stayed the same at 52 still under full load.
I think the duct mod is in order to feed the CPU cool refreshing air......
Well bumped the FSB up to 840, running at 3352 and its cooler again
49 CPU and 28 system.
Wierd, would have expected the opposite
