Is this too hot?

[gremlin]

I've just installed lm-sensors on a Linux box, which is running a Celeron P2-366. It's reporting the temperature as 89c. Does this seem a tad high to anyone? It's just got a regular heat sink and fan on it, but I would've thought it'd be lower?

 

[gremlin]

Oh N/M, according to this site the FPGA Celeron 366 is expected to run at 100c anyway!

Eggs a la Intel, anyone?

 

[Durzel]

100c is almost certainly the maximum (a.k.a hysteresis) temperature the processor should run at. It also usually denotes the temperature at which silicon migration would take place (i.e. irreversable hardware damage to the core).

89c is NOT a healthy temperature for ANY processor.

Burn, baby, burn!
Intel inferno!

etc...

Celly 366s used to be brill little overclockers with just the regular fan. Can't imagine it would clock that far if it's at 89 now

My P3-1gig gets too hot all the time. I've got the cpu warning set at 60 C and it goes off really often if I'm running at 1gig. Currently underclocked (hardcore underclocking skillz ) to 860 ish :/

I'm sure it shouldn't get to 60. I think my Alpha cooler is fucked. It used to work fine on my p3-650. Kept it under 40 C when under full stress and running at 780 ish. I've reseated it a squillion times but no better

Well thats not good then. There's no info on the CPU, the BIOS detects it as a 366, so I (possibly wrongly) assumed it was. Maybe i've overclocked it by accident? Could the clock multiplier be wrong?

fan1: 6750 RPM (min = 6000 RPM, div = 1)
fan2: 42187 RPM (min = 6000 RPM, div = 1)
fan3: 21093 RPM (min = 3000 RPM, div = 2)
temp: +89 C (limit = +60 C, hysteresis = +50 C)
vid: +3.50 V

I assume "temp" is CPU core temp.. not anything else? (The hysteresis value is set in a config file, not detected).

 

[Durzel]

Your best bet to be honest is to read the temperature values as reported in the BIOS (I assume it shows them somewhere) or find out whether or not the sensor settings you are using are correct.

Im a little confused as to the readings being given off for FAN2 and FAN3. If any of your fans truly did rotate at 40000+ rpm, your computer would shake itself to pieces (even the fastest Delta fan only operates at about 7000rpm).

My P3-1gig gets too hot all the time. I've got the cpu warning set at 60 C and it goes off really often if I'm running at 1gig. Currently underclocked (hardcore underclocking skillz ) to 860 ish :/

Your heatsink/fan is mounted incorrectly then. As a general rule of thumb processors (especially Intel procesors which are traditionally pretty cool) should operate within their specifications at their rated speed with no problems whatsoever. If you have to underclock your CPU to get it to run under 60c, then you have a heatsink/fan problem.

Stu might be able to offer some more info. on this, he has a P3 1Ghz as well.

...looks like you'll have to wait until the medication has worn off.

 

[Dimebag]

The reason fan2 and fan3 are showing such stupidly high rotation speeds is because the deviders are wrong

looks to me like you are using mbm5 right?

It says in there the deviders you should use for certain fan speeds.

Anyway, back to the 89 degrees celeron, and heres the statement of the century "Theres something wrong there lad"

Liek durz said check the bios and see if it gives a different reading to mbm5, 89 degrees is not a good temp to run at, i would have a fit if mine went anywhere near 60

Another thing to do (this wouldnt make the heat this high of course, but its worth changing) is see which way the fans are blowing on the heatsink. Make them blow down onto the chip.

Other than that I have no idea why it would run so high :|
If the BIOS has picked it up as a 366 then a 366 it is (if its auto detecting and not done with jumpers?).

----

Oh yeah just noticed... Your Vcore 2 is stupidly high isnt it? I remember back when i had a k6 2 and it used dual voltages but im sure one is meant to be lower than the other by a long way?

Also your 3.3V is a bit low, make it 3.4 for stability

It's not 89 Farenheit is it? that would be much more reasonable

Down? I thought the best thing was to always extract the hot air away and out? Let it draw cool air in from outside the case.

Heh heh. I bet it is...

 

[Dimebag]

/me looks at gremlin, its not F is it? Ill cut you if it is.



Btw ive always heard that best thing to do with a CPU fan is have it blowing down onto the chip, then the hot air shoots out the sides of the heat sink and dissapates? That is if you have a good air flow comming to the cpu in the first place, if you havent then I spose it doesnt really matter what way it points.

Dime

 

[Perplex]

Christ almighty you lamets. Fan should blow air ONTO the heatsink/cpu

 

[old.Anatoly]

the intel one that came with my procesor sucks it off.
Or are they just muppets at making fans?

 

[Perplex]

you got a shit fan then. the 3 intel HSF's I have all blow air ONTO the HS, as does every other HSF in the world

 

[gremlin]

Ok, I checked it in the BIOS, it says CPU core temp is 35 *phew*. I checked the lm-sensors config, it should definitely be reporting in celsius, must be sommat wrong with it.

I assumed the funky readings for fans 2 and 3 were due to the fact that the system doesn't have a fan 2 and 3.. but, you know, whatever

Whats a vcore2 when it's at home anyway?

 

[Summo]

Boh! Let's GET 'IM!

/me swaps fan round

 

[DAN200]

Ohhhh, when i saw the title of this thread i was expecting to see a bit more than processor temperatures!

 

[DAN200]

btw, to lower your temperature just coat the thing in heat sink gel.

 

[Testin da Cable]

Dan sez: "coat yer thing in gel"

 

[Durzel]

Ohhhh, when i saw the title of this thread i was expecting to see a bit more than processor temperatures!

Speaking of which.. Mmmmm.. Faith.

 

[old.TUG]

1) It wouldn't work @ 89c, no way would it be stable
2) I am an overclocking and cooling genius
3) If your CPU cooler uses a shroud, then you'll probably find the best results will come from having the fan sucking air AWAY from the CPU. Otherwise, have the fan blowing onto the heatsink as mentioned above
4) I 0wn j00 all
5) My ol' Celeron 366 did 616 with air cooling and me ol' C300a did 504 with the Intel retail HSF on.. coolskio.

 

[Durzel]

It doesn't require a degree in physics to be "good" at overclocking, any moderately competent person can achieve decent results.

 

[Summo]

Um... what's a 'shroud'

My fan (CoolerMaster Copper) is mounted on the heatsink the way it was delivered, logo up, sucking air away from the CPU. Why should I change it?

It can't be incorecctly mounted. I've done it about 6 times now and got the same result every time doing it how it says in the instructions

 

[Summo]

Have you added new gel, Mister Wij? CoolerMaster say you must add new gel or pad whenever you part the fan and heatsink.

Make it so.
