Celeron Tualatin 1.4Ghz Load Temp of 51 degrees C?

[Mullzy]

I just picked up a Celeron Tualatin 1.4 and am surprised at its load temperature. I'm running it at stock specs with the stock hsf configuration. Either gaming or running a CPU load util I can easily get to 51 degrees Celcius. I haven't let it cook steady for 3 or 4 hours to see if it will get any higher. I don't have a case fan atm (just the psu fan is moving air) so my system temp hovers around 36 degrees celcius.

I'm going to add a case fan this weekend and hopefully drop 5+ degrees off my system temp, but I'm not sure if it will have any impact on the high load CPU temp. What's the *normal* load temp for a Tualatin 1.4 Ghz? Forgive me if this is trivial, but I thought I'd seen several posts here in the past with people running Tualatins at < 40 degrees (using better hsf configs, but nothing you can't buy at any pc shop). I thought some of the nicer hsf setups would drop 5 degrees for you, but not 10-15.

Input, suggestions? Thanks!

EDIT: Oh yeah I forgot... It idles around 45 degrees (after it's been heated up nicely). This morning I turned the PC on and immediately started a CPU load util. System Temp was still around 28 degrees C when the CPU hit 48 degrees. I shut it off and went to work before it could hit 51, but there was a full 20 degrees difference between CPU and Sytem temps.

That is very hot for a Tually.

OK thanks, it seemed high but I wasn't sure if I should be concerned.

My power supply fan isn't really moving a lot of air... well at least compared to my old C850 system case. Maybe a good case fan will help a ton. If not, I'll try re-seating my heat sink I guess.

 

[oldfart]

Make sure the HS is not on backwards. The notch lines up with the raised part of the socket.

Maybe your mbrd measures cpu temps via the internal thermal diode? ,if so then it'll show higher temps & react quickly to loads.
Either way though your case temp is on the high side ,fit that case fan ,also make sure your PSU fan is exhausting air ,some don't!

And yes lowering case temps will also lower cpu temps as a result

Just an update...

I popped in a case fan and dropped my case temp down to 25c depending on room temperature. My CPU still hits around 48c under load, but I do notice the temperature climb immediately as you mentioned. So maybe the temp I'm finding for my CPU is different than the standard people are using here?

For example:

- Idling my system temp will be about 25c, CPU around 43c
- I start running a CPU load program and the CPU will hit 45c in about 10 seconds, 50ish in around 2-3 minutes.


I tried using MBM to monitor my fans/cpu temp, but I couldn't find a sensor which would read the same as my bios (or the gigabyte mobo util). The highest MBM sensor temp I could find was around 38c (higher than my system temp but lower than my bios CPU temp). Is this maybe the sensor which is a better indication of temperature? In MBM I never found something that said "CPU Temperature", just 3 different settings all something like VIA234235 (completely made that up).

Do maybe I am looking at the internal thermal diode temp.... hopefully.

Just got a 1.3 Celeron as well. Using it in a not so well ventilated casing and the temp was like 51C idle. Haven't had time to do any stress testing. Using a MSI 815-EPT Pro-R mobo. Not sure if it's using an internal diode to measure the CPU.

BTW, anyone has any luck OC-ing a 1.3 Celery?

That sounds normal. You are fine.

These Celerons generally top out at around the 1.4-1.5GHz area ,some hit around 1.6GHz!:Q

Re MBM ,have you checked out MBMs site to see which setting you need to use for each sensor?
Also you may need to use some sensor 'compensation'

I've had (3) 1.4 Tuallys and all of them went to 1.6 @ default Vcore. One would go there undervolted to 1.35. The other two I never tried. 1.7 is usually where the ytop out.

 

[Assimilator1]

Wow!:Q ,I guess the latter ones do much better then
Most peoples reports I've seen say they can't hit much more than 1.5GHz

 

[oldfart]

That was on the early 1.0 - 1.2s. 1.4 ->1.6 @ default or less Vcore is a given. I dont think 1.7 would be very hard. The newer lower clocked CPUs are also doing well.

 

[Assimilator1]

Wierd ,I must of had a bad cpu then as it wouldn't go above 1.46GHz (133FSB) & I know the RAM & mbrd are good for 145FSB.
vcore is 1.55v ,I guess it could of gone a bit higher with higher voltage but I didn't try.

 

[oldfart]

Yeah, it always a gamble. I never tried a 1.1. I like the 1.4s since 1.6 is a given, and they come with a bigger HS/F. I've put them in as upgrades in BX boards. The lower FSB is good to keep the AGP closer to spec.

 

[ugh]

Any of you guys here use the thermal pad that comes with the CPU or do you apply AS2/3 on it?

 

[oldfart]

I prefer AS2/3.

 

[Assimilator1]

I've only got Silicon HS paste & I use that.

 

[ugh]

Any major differences between those two?

 

[Assimilator1]

Silver paste is better ,I believe it would knock off at least another 2-3C over Si?

 

[alkemyst]

Many times it's the other components not the Tualatin that's limiting....

51C is high regardless...I am at 33C case and get 41-42 at load with a slk-800, on my pep-66t 45 would be a high.

 

[ugh]

I guess I'll need to get the casing a bit cooler then

 

[alkemyst]

I would say case cooling doesn't hurt. I have a quiet set up with 5 case fans. I am using Power PC and Cooling's 80mm silencer's now and it's nice.

 

[ugh]

I've retried my 1.3Ghz Tually. It's idleing at 51C and my case temp is 47C. Argh... Don't know how it got so high. My other machine's case temp is only 32C and the CPU temp is 43C. This rig needs SERIOUS cooling....

 

[oldfart]

47C case temp?? Di d you case fans stop working? That is really high.

 

[Assimilator1]

Jesus thats high for case temps!:Q

Hottest I ever had was 42C & that was mid summer ,with a room temp of mid 30's & before I had 2 case fans.
