Recommended Temp?

[Redestium]

For a P4 3.0 Ghz? When I do DivX encodings the CPU temp gets to like 83 Celsius is that normal (it's around 56 when idle)?

[my name is ben]

wow! that sounds high my p4 3.0 (with intel heatsink/fan) is 31 celcius when idle and never goes above 45

[sciguy007]

if that temperature were true, your processor would be frying. something isnt right. thats VERY VERY HIGH.

[Redestium]

That's the temp I get from my motherboard (Asus P4C800 Deluxe-E)...:unsure:

[sciguy007]

check and make sure your heatsink is not angled on top of your cpu. that temperature is way high. is your comp unstable at all?

Been running fine for about 4 days now for extended period of times. When I installed the chip and HSF (boxed retail, btw) I made sure it was all secure and seated flat. I'm getting worried now though... :(

[OPaul]

The high and low operating temps are on Intel's website, I've found them before but can't seem to right now. However 83 does sound a little high.

Processor shouldn't' fry, it will melt around 100C though.

[sciguy007]

id say measure the temperature with any other means you have, like some sort of external temp probe. perhaps the board has a bad sensor because i think the thermal spec for p4s is around 75 C.

[episode]

Mine idles at 45 or so, 53 under load, when I turn my fan up (I have a Thermaltake Spark 7+ Xaser Edition) to about 3400 rpms, it idles at 37-38

[Redestium]

According to the Asus Probe software the CPU fan is at 5000 RPM and the CPU is at 55 C, and all I'm doing is typing this post....I don't see how I could have not seated the HSF correctly but I will have to check now to see.

So around 70C - 75C like sciguy007 said.

[KTamas]

50?C i think the normal

[Redestium]

Would having performance mode on (since I have the canterwood board) be a cause for the heat increase? It also reports that my mobo is 32 c, just some more information.

[sciguy007]

the performance mode (PAT right?) shouldnt increase the temperature at all, since thats a feature of the i875 chipset and not the processor.

Yeah that's what I was talking about.

How would I know if the HSF is not seated right? When I installed it I tried jiggling it to make sure it was secure and it didn't budge and looked flat as far as I could tell. If it was angled in any way it would move, correct? :unsure: :unsure:

it would probably wiggle if it were not on right. the stock heatsink really latches down securely, so it should be relatively easy to tell if its on right or not. if it looks to be alright, then maybe your board just has a bad temp probe, but you cant really verify that without a measurement from somewhere else. if your computer is stable and everything is secured down, id say the board is reporting the temp wrong.

When I was locking down the HSF I could tell it wasn't seated right when I would try to move it slightly a corner would feel loose. Then I just pressed a little harder and everything clicked and when I tried to move it again it was solid and wouldn't budge. Since I've built it I haven't had any lockups or crashes and have been playing a fair share of WarCraft III in addition to some encoding. So I'm not really sure what's going on anymore, lol. I think I'll try contacting Asus to see what they have to say. I'm running the latest BIOS as well for that board.

edit:

Just emailed Asus and I'll see if they have anything to add. Is it possible that I somehow damaged the CPU probe during the installation of the HSF? The CPU and Mobo probes are separate right? The mobo temp is around 30C, which is about right I think. Damn I'm going nuts.... :wacko: :wacko: :wacko:

Well I tried emailing Asus but they haven't responded (actually I got a delivery failure :angry: ). I also found when trying to use the BIOS update utility that it told me that it didn't find an Asus motherboard! How the **** does that happen?! Something is royally screwed from what I can tell. I also touched the heatsink when it was reported at being 82C and it wasn't even warm. I am interested to find out what Asus will tell me (if I can ever get through), I am thinking about just RMA-ing the board back to newegg but damn that's a hassle considering I can't really afford the downtime...

Also does the P4 throttle down when it reaches (or thinks it reaches) certain temps? I?m trying to figure out why my DivX encoding is slow when I have all the settings set up for speed. I was also wondering where the thermal probes for the motherboard and CPU are located. The motherboard temp seems correct (30-32C) so I can?t figure out why the CPU is so messed up.

Don't trust your motherboard!

If you're monitoring your CPU temperature with some sort of software utility that reads a motherboard sensor, beware. It's better than using a sensor stuck to a heat sink, but it isn't necessarily a lot better.

Socket A motherboards that can monitor CPU temperature usually have a probe behind the CPU itself, in the middle of the socket. If the probe's touching the back of the chip package, it'll pretty much tell you how hot the chip package is.

Unfortunately, the hardware that reads the probe output may or may not be reliable. People's hardware-monitor temperature readings sometimes change drastically when they update the BIOS version of their computer. The temperature, of course, has stayed the same; it's the calibration of the monitoring hardware that's changed.

And many behind-the-chip probes don't quite touch the CPU.

And probe readings are susceptible to changes in ambient temperature that soak through the motherboard.

A better way yet to monitor CPU temperature is with a thermal sensor inside the chip package itself. All current Intel CPUs have a thermal sensor, which better motherboards can read; the new breed of AMD "Athlon 4" processors apparently have an internal sensor as well.

Internal sensors aren't right smack dab in the middle of the CPU core, but they nonetheless give you a quite good idea of the chip temperature. They're still at the mercy of the monitoring hardware calibration, though.

Is it possible that the BIOS update that I did (to the latest version) screw up the calibration of the CPU sensor? I don't remember the temp prior to updating the BIOS though. :unsure: :unsure:

[A10]

Most newer Socket A motherboards read the cpu temps from the internal diode inside Athlon XP's older processors need a probe Athlon 4's haven't heard that name in a year or so. Odds are either you aren't getting full contact with the cpu heatspreader you forgot to remove the tape covering the thermal pad or you have a bad bios flash. On most motherboards the motherboard temp sensor is either located in between the pci slots or sometimes oddly inside the northbridge. The thermal probe or probably diode is located in the center of the socket. Another possibility is the heatsink bracket isn't holding the heatsink in right you might want to look at it.

IIRC it reads it directly from the processor, so you shouldn't have to worry about damaging an external probe. Also if it's not even warm, are you sure it's not 80? F?

I don't get it...

I am sure that there is flat contact with the CPU, there was nothing to peal off on the bottom, it was just a gray slab, and the heatsink is secured very tightly. The only thing I can tell is that the sensor is misreporting (C/F)...:wacko:: :wacko:: :blink:: :unsure::

[darkmark327]

The applied goop is only good for one attachment of the heatsink...if you remove the heatsink, you need to apply new stuff.

[youm0nt Veteran]

maybe asus probe isnt very accurate? :huh: you could try getting a infrared thermometer or get one of those 5.25" temperature displays that use a thermal probe you place on the cpu,gpu,chipset etc.

[uniacidz]

Hmm, Asus Update not reporting that you have a Asus Mobo. Very strange.

Does something like the System Properties show that you have a Asus Board? Eg, Start Menu/Run and type in msinfo32

Man, returning it looks pretty good to me.
