Woo forums back! Nice to see yous all :D
Celeron 1gig coppermine @ stock 100FSB @ about 55 degrees depending on room temp and load. This is with the stock cooler which has quite a decent sized heatsink and a 4200 rpm fan and cellys ares sposed to run cool :(
I bought it for $130 from a mate of Fraz(OCNZ member) and at that price I would expect it to not run so hot I will have to buy a fricken bigass cooler, I am displeased :mad:
With the case off I can lose about 5 degrees but I shouldn't have to put up with the noise so does anyone know any cheap and quiet skt 370/skt A coolers? I have plenty of headroom for a real bigass heatsink if there any u know of.
The wretch who sold me this piece of junk wont assist needless to say.
Will the cpu just not last nearly as long at this temp, the PC seems stable so far but I dont know if its affecting performance at all.


I installed it myself on a new skt 370 mobo which has autodetect voltage and it says its running at 1.75V(stock) and the FSB is at stock 100FSB so I think the cpu has just been thrashed unless there is anything else I could be doing wrong. This was my 1st PC build of any sort.

Can I ask you just one question:

WTF are you on about re: the CPU being thrashed so it runs hotter?

Sounds like a load of BS that.. You bought a 1gig Celeron and thats what you got..

Did you use thermal paste?

I would also get a couple of case fans if i was you

:-/

$0.02

Yep I used basic thermal paste, I shouldnt need arctic silver with a celeron. Seeing as I paid $130 I would expect the stock cooler to be more than adequate like it usually is, I shouldnt have to buy an aftermarket cooler for that price, if he sold it for say $60 or $80 or something I could live with it running too hot but 55 degrees idle in a cool system is bull****
I think Ill only do priv sales with OCNZ people now.
I thought about getting a case fan but system temp is only 25 degrees, maybe I just need a really humungous heatsink, Whetu just to check did u mean Volcano 7 or 7+?

Regarding cpu being thrashed, lol I dunno I just thought if it had ben OCd a lot over time the silicon or whatever might have degraded a little bah, I dont see how its running so hot unless the cpu itself is stuffed cos Im thinking cellys should be 25-35 degrees stock. I dont think it has been OCd much anyway as it would be unlikely to get more than 133FSB out of a 1gig coppermine, I could only get 115fsb with the Gigabyte easytune thing. So no big voltages or anything like that cooking it.

And yet you STILL aren't suspicious that those temperature readings MAY NOT be 100% accurate?

And I suppose if the ambient temp is 15°C, and it's been off for hours, then you turn it on, go into BIOS, get a temp of 55°C - I suppose you'd then BELIEVE that temp??
:confused:

You MAY want to make sure those temps aren't straight out of your mobo's @ss first! I'd suggest checking the BIOS readings straight after POST after it's been off for a few hours....

Yep KJ after checking everything my 1st thought was that the sensor was stuffed so I got a computer guy to feel the heatsink and he thought yep it was too hot.
Before that I checked temp in all those situations, I checked in windows with SiSoftSandra then rebooted into BIOS and temp was almost the same.
In a cold room at boot after being off for hours its about 40 degrees in BIOS and climbs to about 47 after a coupla mins.
Having the case off is about 5 degrees dif.

At the mo its 49 degrees with case off in normal room temp after doing windows stuff, the heatsink is not warm, its barely even lukewarm,its just not cold ;)
The RAM is slightly warm.
When the temp gets around 60, the heatsink is definitely warm but never hot.
I dont know if anyone with experience of the fc-pga celly heatsink thinks this means my sensor is likely accurate or not:)
The computer guy thought it was but I dont know how much experience he had of this stuff.

If I meant 7+, i would have said 7+ ;)

You'll see why I have come to this conclusion (best bang for the buck silence HSF IMO is the volcano7) soon enough ;)

heh heh heh *chuckles evilly*

Sounds to me like your sink aint contacting your CPU properly: If your CPU was around 50, then your Heatsink should at least be warm to touch, if not quite hot. Seeing as its not, then its obviously thermally insulated from your CPU core: either not sitting straight or the Themal goop aint doing its job. :(

Whetu: I take it by those comments you have a review on its way? Huh? :)

chuck it on a another mobo and see what temps you get there,

also i had my 850@1250 @1.9V and it was only doing about 10°C above the room temp with a volcano 2 i think it was,

either, your heatsink is not on properly or i don't know,

remember that the stock intel heatsink is made so that the CPU runs below 60°C, they don't care,

there something wrong with something else apart from teh CPU, can't be 55°C, unless you have a fan heater blowing into it? (I've seen this happen, the guy was like, oh, silicon chips can run up to 120C, no need to worry about it :mad: )

The heatsink is def on properly, I mean u just clip it on and the paste is all smudged so its def contacting the cpu, I took the tinfoil square that has black smudgy stuff on the bottom of the heatsink off just now to see and its about 5 degrees hotter so erm better put it back aye.
How long should the cpu take to lose all its heat after shutdown? Ill try again and if its reading crazy temps right off the bat like KJ says the temp sensor may be stuffed.
Id love to try the cpu in another mobo or suchlike but the only computer geeks I know are the ones that charge me $65/hr :(
How long would the cpu take from cold boot to get up to normal idle temp? Would 50 degrees in BIOS, 20 secs after being off for hours be abnormal?
If my mobo is reading temps wrong fine no prob, if not the worse I can do is wear out a cpu quick right?

I got no heaters or anything dumb like that making it hot, case temp @25 when cpu@60 so thats not it. The paste Im using is those little packets u get with new cpus, someone gave me a whole lot, ok so its not as good as Arctic silver but it shouldnt make that much diff.

Take the heatsink off

Clean the bottom with something like isopropyl, meths, or your sisters/mums/gf's nail polish remover

Clean it up real good.

Then take a real good look at the bottom of the heatsink.. is it flat..?

Clean up the cpu and take a real good look at the core.. is that flat? I mean really flat.. no slight dip in the middle..?

If either is not flat use google and do a seach for "CPU lapping" or "heatsink lapping" or even just "lapping"

Yes to both Ragnor, both are flat as a pancake.

Sandra came up with this in "Mainboard Info"

Notice N2527 - A compensation value (calibration constant) was added to external temperature sensors. Depending on the CPU type, a compensating value must be added if the temperature sensor does not actually touch the CPU. This correction is not defined for all CPUs and there are exceptions to the rule. Don't compare the BIOS that is tuned for your board with Sandra which must work on ALL boards!

Fix: Right-click module, select Options and uncheck Use temperature compensation for external sensors. See the System Monitor topic in the FAQ for more information.

Warning W2528 - System monitor device implementation is known to vary. System monitoring devices can be used in different ways on different mainboards (e.g. sensor 1 measures CPU temperature instead of board temperature or Vin1 measures +5V instead of +12V) rather than using the manufacturer’s implementation guidelines that we’re using. The software will show incorrect data in this case as it cannot know the specific implementation details.

Fix: Let us know so we can attempt to support your board. As always, assume the BIOS is right as it is tuned specifically for your board rather than being generic like Sandra which supports thousands of different boards.



Anyway, been @ 55-60 for 20 mins now and heatsink is not even warm, RAM is very slightly warm, guess the sensor is wrong.

Oh well if teh sensor is wrong I apologise to Daniel Roberts who sold me the cpu for abusing him :rolleyes:

yep,

tell ya what,

run your cpu in idle and touch with your finger the heatsink and see the temp,

then,

run it at full load, and see the temp on the probe, and touch with your finger, if the heatsink is warm, then it's about 30°C, if it's getting hot and not comfortable, then it's about 40C,a dn if it's burning your finger then it's 50°C.

BTW, might pay to get a thermistor and measure the temp with it, do you have one, like a temp probe, eg, Jaycar sells a multimeter with temp probe for about 30-40$ and they are good.

OMG I just read Whetu and MirdOCs excellent Cooling FAQ (yep shoulda done b4 sorry) and link to a link to a link there got this excellent CPU IDLE app http://www.cpuidle.de/ which reduced my cpu temp from 70 to 35 in seconds WTF!!:eek:
Anyway prob solved I think as my HSF and RAM actually feel cooler:)

BTW My temp sensor is a probe that sticks out of mobo into underside of cpu

your lucky, i can't run idle programs, they don't work for me :(
