72 deg.C on P4 3Ghz with Abit IS7-E

[BespinReactorShaft]

Hi

Just got my new P4 rig last weekend. The CPU is a P4 3.0E GHz (the recent 1MB cache version) on the Abit IS7-E mobo.

I've been using the Abit "EQ" temp/voltage monitoring program (as well as the BIOS "PC Health" function) to check the temps and the "Core" temp is hovering around 72 deg.C or so., give or take a couple of degrees.

Fans are all spinning (heatsink, two for casing -- bottom front + top rear). The rig's been on all day long Sat and Sun, and overnight last night and there's been no random crashes so far. The load should not be 100% (only a single SETI@home thread is running).

The assembly was done by the vendor. Is this a faulty heatsink, or more due to buggy Abit monitoring software?

Thanks for any clarification.

p.s. I've also got a ATi Radeon 9800 Pro 128MB (256 bit mem width) installed, fan is running, in case this affects anything.

abit boards over read the temperatures by 5 degrees C or more. that temperature is high, but subtract 5 and it's not as bad as it might look.

Running a Prescott at 100% usage in a Abit IS7 72c sounds about right.

i wouldnt worry too much about it but 72 is getting kinda high.

here's a little reading you might find interesting...

My 3ghz northwood sits at 72C when it's folding with an Abit IC7-G. Mine is tested to report around 15C high. As long as your PC is stable, don't sweat it.

 

[Bumrush99]

that seems really high.. is that the "E" version of the p4? My P4 3.0C ran at 33C, 42-45C under full load.

 

[imported_michaelpatrick33]

If it doesn't crash or randomly reboot I wouldn't worry about it. The Prescott's do run hotter than the Northwood's and I have seen temps in the upper 60's under load.

I have a question that no-one has to answer if they feel it is off topic.

At what temperature does the Prescott cpu begin to throttle back (or does it at all)?

That seems high. In comparison, my P4 2.8C running at ~3.2GHz runs mid 40s idle and low 60s full load, and this is in tropical Singapore. If I take it up to ~3.4GHz I'll idle ~50C and fully loaded it'll go well into the 60s, but this is with 1.65Vcore. I have the Swiftech MCX4000 though.

Try updating the BIOS to the latest version, it fixes, or at lease reduces, the high temp "bug". Also, what HSF are you using and are you overclocking/volting?

 

[BespinReactorShaft]

My P4 ("E"-series) rig is also living under tropical conditions. Kuala Lumpur to be exact ;-)

My HSF is probably the Intel stock (came with the P4 box?).

And no overclocking whatsoever.

I believe it is most likely the Abit BIOS. Even so, to reach low 60's it'd have to have been offset by 10 or so deg.C, which is kind of a big jump, dontcha think?

But the rig I've left on with SETI@home (2 concurrent threads using HT) for two days running now. No random crashes or molten plastic anywhere. The heat dissipation has sorta raised my room temp though. ;-p

Still, I'm not totally satisfied with the "no random crash == hunky dory" philosophy. Maybe the extra degrees are giving a negative performance hit. I ran 3dmark03 last evening (Catalyst 4.6, AGP accel enabled, no AA/AF, 1024x768) and it came up to be just over 5800 points. Not sure if this score s*cks monkey balls for a non-OC'ed configuration.... ;=/

Pls do have a look at my current rig below for more info (as the "my rigs" links is still buggy):

P4 3.0E GHz, 1MB cache, 800MHz FSB
ABIT IS7-E
Kingston 400MHz DDR PC3200 2x512MB Dual Channel
ATi Radeon 9800 PRO 128MB (256-bit version)
Western Digital Caviar 200GB 7200RPM
WD4000 40GB Protege 5400 RPM (secondary)
Samsung SM-332 DVD+CDRW combo

 

[Goi]

5800 is quite a respectable 3DMark03 score for the 9800Pro I think, if everything's stock. I'm not sure of the normal operating temps of your CPU in hot countries like ours, perhaps you could post in some local hardware forums and ask around.

 

[Nebor]

No, the heat is not hurting your performance. Furthermore, the heat isn't even THERE. Feel your heatsink, that's what finally made me realize that there was no way my temperatures were accurate. Turns out my Abit reads about 15C off base. THey did release a BIOS flash that lowered reported Prescott temps for peace of mind though. I'm on a C chip though, and I'm reporting quite a bit hotter than you. Don't sweat it, I've been up for a year just fine.

Actually 72C is about right for a prescott. I've read that it pegs to 78C under heavy load with CPUBurn with ambient case temps of 20C.

You definitely need to get better HS/fan and have at least 7V to 12V for the fan to get temps around 45 - 65C range.

Why does he need his temps in that range? There's no reason they need to be... Does he need a 650W power supply too? :roll:

 

[BigBadBiologist]

You should feel the aluminum part of your HSF. If it doesn't feel at all warm, then your HSF may not be making proper contact with your CPU.

BUT, 72C doesn't seem all that far off for a Prescott.

 

[BespinReactorShaft]

I've just upgraded my bios to the latest version from Abit. Now the temps are in the low 60's (full load).

Yes, I just discovered some interesting facts about Prescott (boy I'm starting to regret getting this instead of the Northwood.... ), especially the Prescott-IS7 combination....

My 3.2e is at 55.5 on my external probe 62c with the mobo's reading. At idle. I had it at 4.016 yesterday running at 73c while gaming. No crashes, no issues at all. Just hot hot hot. I've got one hell of a water cooling setup too...

 

[BespinReactorShaft]

RGN, do you mean 4016 RPM fan speed?

If so, check these out (from my Abit EQ):

Fan speeds
- CPU 4218
- NB 5818

Temps (Celcius)
- SYS 48
- CPU 65
- PWM 57

I wonder if I should start taking some pride in owning a IS7+Prescott combo..... maybe I should start calling it the Greenhouse Goblin instead.

::LOL::

Heh, no I'm talking overclocked 25% to 4016Mhz. Since then, I've ran at lower speeds, but the temps are about the same... Still higher than I thought.
