Cele-800 CPU temp and myterious loading in Windows ME

[Philip]

Hi,

I bought a Celeron 800 and FIC FS39 mobo last week. After putting everything together I found the CPU temp is like 48C at idle and 60C at full load, just wonder are these temp too high ? I'm using the standard heatsink and fan that came with the CPU.

Also, the OS is Windows ME, and there seems to be some myterious system load occupying 20-50% of CPU time, is there any way to locate what program is accounted for this? (in W2k, this is easy, but this is Windows ME !!!)

Thanks in advance.

YIKES !! Yes, those temps are way, way too high. Are you using the OEM intel heatsink/fan, or did you get an "aftermarket" replacement??

I'd have to say that the hsf isn't sitting on the chip squarely (ie level, flat against the chip's die). If you are using an alternative cooling arraingement, what did you use for a thermal compound between the chip and hsf??

Please post a bit more info on the componenets inside your rig...we can help a lot more if we know what parts you've used, what settings you are running at (core voltage, FSB, etc...).

Mr B

*silly me...missed the line about using the standard hsf.... you really might want to look into getting an Alpha or GlobalWin on that Celeron....and using some Arctic Silver thermal compound instead of the intel "heating pad" is a REALLY good idea.*

I have a Cele 800 and at stock everything(100Mhz fsb and 1.7v) it runs hotter than my cele 633 @ 1017(1.95v)...

Not quite as hot as yours but I get 37-40c under full load, and that is not overclocked! It will runn at 1066(133FSB @ 1.95) but I had to shut it down, it was WAY TOO HOT. I will have to put my watercooler on it.

Okay, I didn't overclock my Cele-800 so it would be running at 100FSB with 8x multipler. From the BIOS PC health screen I can see vcore is 1.7, vio is 3.39, these two voltages do look normal to me. I also thought the same that the HSF may be not touching the die well, but I touched the HSF with my fingers and it felt as hot as 50C I would say. The thermal compound that I used was the same kind that came with FOP32. I've got this HSF (FOP32) too but my chassis is micro-atx so it won't fit in.

Do you guys think the motherboard or power supply would made any difference? the mobo in use is from 'FIC' which isn't any big name in the market, and the power supply is a 150 watt one, this is very suspect to me !

Regarding the myterious system load, I tried installing w2k on the same computer and the CPU is normal, so I think this problem is specific to Windows ME. Any thoughts?

[outhouse]

Ive heard that if you use a power supply unit that is not strong enough that it can cause temps to increase i think 150 is a little small even if your just using a stripped system you may want to get a bigger PSU if your using allot of hardware then you really need a bigger one. This may not solve your heat problem but it would be a good place to start.

Also what are your ambient temps? do you have good case cooling? these will definatly contribute to high CPU temps.

As far as windows goes have you got into your startup settings going through msconfig and cleaned out the programs you dont need at startup? also hit Crtl Alt and Delete once and look and see what you have running in the background, have you set your PC as a network server? system restore also uses quite a bit of disk space and may use some of your system resourses you can try and disable it and see if that helps before i mess with any of this i would address your temps first get em down and keep her happy

good luck

I also got the same feeling that the heat may be generated from the power supply indeed. I ran another Celeron 400 on the same chassis before, at 400Mhz the heat was okay, but every time I overclock that to 550 the whole thing would become as hot as it is right now (50C).

[Philip]

My problem should be PSU related. I tried giving the mobo a 300Watt PSU to work with then ran the system at 117x8, the CPU temp went down to 48C (from ~60C a day ago) after 5 minutes of heavy load. At idle time the temp became 44C.

I also tried inverting my computer case so that the PSU position became higher than the CPU (was below the CPU before), the temp at full load came up to 55C this way. I guessed when the PSU was below the CPU, the hot air came out simply ran through the CPU thus made it hotter.

Regarding the myterious CPU usage under Windows ME. I found that happens in the KT7 mobo too, maybo this is common for such OS. Have you guys notice anything while running the CPU monitor program?

BTW, thanks for all your input so far.

Rgds,
Philip

Mine is mildly OCed right now (see my siggy) and it runs 24-26C idle and 33-35C under full load (seti running). I only got these low temps after re-seating my Alpha a few times! The last time I used thinner to clean the die and base of the heatsink and used a plastic bag (don't apply the paste with your bare finger!) to apply a thin coat of the silver paste that came with the Alpha. The coppermine-die is just soo tiny that it can be very rewarding to try and reseat your HSF a few times when you're in doubt about temps. I found that when you (accidentally bump against it or apply pressure when mounting the slocket on your mobo) move the heatsink for only a mm, half of the paste is gone! They didn't enlarge the thermal contact area on the new cDO chips for nothing!!!

I vaguely remember reading from somewhere that ME searches constantly tasks to process. This would then cause the constant processor load. Something like that...

I have noticed the same thing. Even every possible programs closed (only systray and explorer on) there is load. When moving mouse on desktop load drops to zero for a while! Could it be that Windows anticipates some action and stops whatever it is doing?

[Philip]

I observed the same thing, that is, as soon as I started moving the mouse the myterious load seem to be disappeared a while. So I guess ME must be using idled CPU time for doing something.

Probably decrypting stuff for the nsa, no big deal.

Are you sure this is flat on the core. I assumed mine was(don't say anything) but when I went to put my shim on and took the slocket out i noticed it was sitting like this( / ) on the CPU. Part of the core was not touching the heatsink. Everything had been fine, and I don't monitor temps(I am too lazy to install that probe thing they gave me with my MB) and now with the shim, things seem to be a little better. But I would check that.

[The Stickie]

I don't know why, but my impression is that some of thes PIII just run that hot...
I'v seen several with stock heatsinks (attached well) running til 60°C under load... and that's HOT... too hot...

seems like intel wants us to bow our cpu's...

[William]

I don't know, but those are too hot. I would go ahead and splurge for a good hsf. I would say the Alpha PAL6035 or the Fop32-1 would be great for a celeron. You should get plenty good temps with those. http://www.crazypc.com and http://www.2cooltek.com have them.
