Temp too high on new CPU?

[Philgag]

Hi, I just got a new XP 1700+ and a a7v333 for one of my friend. I have installed good themal grease, not too much, and a volcano 6 cu+ 7000 rpm fan...

The fact is that running normally in windows, the thing stays at 56/57! witch i tough was incredibly hot, it goes to 61 after 30 min of looping 3dmark demo. I have installed a enermax power supply witch have 2 fan + an exaust fan ... so i tough the cpu would run much cooler than that.

For comparaison, my own system, an athlon tbird 1200 barely goes beyond 50 degres under full load! however, my t-bird once reached 57 degres and boy the top of the case was HOT to the touch the case temp was at 41!, but at 57 for 2 hour the new system is not ever midly hot! (32 degre ) I dont know if it could be a problem whatsoever, but i noticed that at 57 degre, asus q-fan puts the fan at 5000 RPM... witch i tough could mean it was kinda normal. Also with the asus monitoring noticed me that the voltage 12v wat at like 13.180 and warned me that it went beyond treshold maybe thats why the cpu is quite hot. Beside that, nothing hangs, and like i said if i wasnt reading the temps id say the cpu is at 45!

can anyone help?

thanks

You said a mouthful. 😉 NP though.
The temps are a bit high. You didn't mention any Intake air. Is there an Intake fan on the case? The voltage seems way off also. Maybe a power supply problem is causing this overheating. If the top of your case was too hot to touch then YOU have a problem too. The case should never be that hot. That again could be an underpowered power supply. The volcano is not the best of HSF's either. However, you should take a good look at the power supply first. If the voltages are that far off then there could be something there causing the overheating. Then look at adding some additional Intake air to the system. After that you could look to a better HSF if need be.

 

[Philgag]

Alright,

Is there anyway I can lower my voltages in the bios ? I'm not really advanced in this field of configuration...

thanks for the help

Don't worry about the temps, Asus boards are well known for reporting them too high, usually by 10 or so C. As long as the system is stable, it's fine.

Asus boards are well known for reporting them too high

In some instances, that may hold up but 68 C is much higher than even "normal" or average ones that are seen; taking into account that ASUS boards are thrown into that "average" already. That argument just doesn't hold up. Besides, I've owned ASUS boards before (and do so currently) and even on an extremely hot day, I don't come anywhere near that. In fact, I've never topped 55-56 C under the worst conditions.
To say that it is "OK" as long as it is stable is nuts. You might as well put on blinders. That would be like driving a car around with hardly any fluid in the radiator that is running close to the "red line" on the temp guage. Since it is running OK would you keep driving it around?? Or would you add some coolant to preserve your engine?

 

[Vic]

Where did you get "68"? And notice how he said the cpu did not actually appear to be hot. Only 2 things can cause high temps readings AND a cool HSF. One is where the HSF is not seated properly and the thermal contact is poor. This is usually noticeable after running for a while, because heat will start radiating from underneath the socket. The other is that the mobo reads the temps too high which, due to Asus' track record in this case, is highly likely.
As for my "putting on blinders," I could say the same about yourself. The engine in my car costs thousands of dollars. I just bought a new 1800+ for $90 shipped from Newegg. Next year, my car will still have decent resale value. Next year, the 1800+ will be worth about $20, if that. Got another colorful analogy?
As for the volcano, I use a TT 6cu (not even the plus) as my test HSF (the Alpha8045 is a pain to install so I don't use it for testing), and I just put a new KT3 Ultra ARU and that 1800+ in my system today and was stress-testing. As I type, I'm torture-testing Prime95 at 1650MHz at 45-46C. So I don't think the problem is his HSF.

Now I would be worried about that 12v rail, that is way out of whack.

To say that it is "OK" as long as it is stable is nuts.

As always, guy, you're way off base. As long as a computer is stable it's fine. I'd be worried about the voltage but the temp is fine. Motherboards mis-report temperatures like crazy and they can be ignored if the system runs stable.

 

[Philgag]

Well thanks alot for the help, I ran the computer for a couple of hours and the cpu heat sink was hot, just like on my 1.2 t-bird. So i think the contact is made proprely. As for the voltage, it's worring me a little. I might check with a other PSU, but i think the one i have used is of good quality.

anyway, thanks alot

Where did you get "68"?

That was my mistake; confusing this with a previous thread. For that I apologize. However, the rest stands. The comparison to a car wasn't about price, it was about methods of dealing (or not dealing) with an obvious deficiency. It was pretty obvious but then again you don't seem to want to deal with the obvious. And by the way, he said the "system" was not hot (32 C) but that the CPU was at 57 C. Read it again!

As always, guy, you're way off base.

And opinions are like......... and everyone's got one. Off base is accepting something that is wrong and putting your head in the sand hoping it will not cause any trouble. Your quote, "Motherboards mis-report temperatures like crazy and they can be ignored if the system runs stable. " is a prime example of that. No one said that MB's report correct temps; they are just a guideline that can be used as a tool to analyze any potential problems. In this case he said his case was hot (41C), not the unit in question (32C). But to completely ignore something that is that far off (the 57- 61C cpu) is not only "off base" but irresponsible. At the very least it would require some scrutiny.
On the brighter side, we do agree on one thing; the power supply needs to be checked into.

Buzz2B and Philgag,

50-60C temps are normal on an asus motherbaord. It deals with how asus compensates the socket-thermistor reading upward. Which is why you can't compare socket-a temps between different motherboards. The only general guideline that can be used is the one versus the same motherboard.

If your case is 41C, and your CPU temp is 60C, that's only a 19C spread, which is excellent on an asus motherboard.

PSYWVic,

That's not accurate. IN fact, in detailed analysis of internal diode readings versus scoket-thermistor readings, the Asus socket-thermistor is still lower than die temperature.

Which goes to show you, if the asus is 3-5C too low, and everyone says its 8 to 10C too high, and there are motherboards that read 20C below asus level, that socket-thermistors can be off by some 25C.

But back to Asus, teh readings are not too high. They are the closest readings to int. diode outside of teh epox 8k3a series.

Yes, that's true. The best of way to decide if a temp is good or not is by putting a thermometer in the case. compare that to what the motherboard is reporting and then look at the spread. It's the spread that's important. Sorry for being mouthy. Don't know what got into me.

 

[Philgag]

Hehe, i didnt intended to start a mini flame war 😛

Well, my own system isnt at 42 all the time , it only went to that last week when it was 42 outside and we didnt have conditionned air.

as for my friend's, i'll try with another power supply and see what happen to the voltage.

thanks

 

[Philgag]

Well,

I tried the computer again today with the case shut, and the cpu temp was 55, now after 3 hour it dropped to 53 idle ( and that's with the 7000 rpm fan runing at 5000 ). Much better than 57/58 yesterday, my guess is that the thermal compound i have used is now starting to get optimal. I have also noted that in the BIOS, the 12+ voltage is marked at 12.6 while in asus PC probe its at 13.12. I don't know about that, but it seem that i thrust more the bios version.

anyway, it seems to be a fine computer

I have a self-owned A7V333-R with a 1700+ at work. It is cooled with an Alpha PAL8045 and a Panaflo L1A and has socket-thermistor readings of about 55C. Complete specs are here if you want to see what case/PSU, etc. I think your 56C readings are entirely normal. edit: by the way, I think there is something wrong with Asus Probe's voltage measurements, it claimed my 12V line was at 13.8V, while the BIOS did not.

More background on the A7V333, if you're interested:

My A7V333-R gives socket-thermistor temperature readings about 8C-10C higher than my ECS K7S5A does when using the same individual CPU/heatsink/fan/voltage. Asus has simply calibrated the A7V333's socket thermistor so the readings are closer to actual core readings. Before anyone asks, yes, the A7V333 monitors the on-core diode for overheat, but you will not have access to that reading, you get a socket-thermistor reading in BIOS and Asus Probe.

Also noteworthy: The A7V333 has Asus Q-Fan. We built an A7V333-R system with an XP1900+ and the retail AMD fan, for a new employee, and I enabled Q-Fan on it. It boots up with the CPU fan at full speed, then begins gradually lowering the fan's speed in order to hold a socket-thermistor reading of 60C. If the temperature falls below 60C it drops the fan speed some more. The system runs great and actually gets pretty quiet after about five minutes of sneaking the fan speed down. In the end, the CPU fan is making about the same noise as the Antec 80mm case fans that come with the PerformancePlus 880, which I would estimate in the ?30dB? area. It sounds like, even with Q-Fan reducing your fan speed as much as possible, you still run below 60C, which is good.

while in asus PC probe its at 13.12.

Wait a minute. After reading that and re-reading your original post I realize that part of the error may be in the reporting of the voltages. ASUS probe has never been noted for its accuracy. Have you tried using Motherboard Montitor 5 instead. I would really advise you to do so if you haven't. It is more accurate than the ASUS Probe.

 

[Philgag]

yeah i tried mbm5 and it report it has it is in the bios : 12.6 witch is more normal.

so everythink looks great after all.. cya all!

 

[paralazarguer]

Try getting 2.16.07. You can get it from other worldwide sites but no the US i think. I saved the installer locally so I wouldn't know 🙂 It reports the voltages fine

 

[Viditor]

Actually, I suspect that it's not a mobo issue at all, but that your new 1700 is a TBred, and the voltage IS too high...
Check the VCore voltage in the bios, and make sure it's set for 1.5 and not 1.75 (if it will allow you). This is a problem I have been finding on a number of mobos and the new TBred (many of the mobos do not have settings for the new TBred in their bios yet...)

Cheers,
Charles

 

[Philgag]

How do i know if its a tbred or not? are the tbred the new 0.13 micron? what exacly is a tbred ( dont tell me to remove the hsf 🙂

Tbred is Thoroughbred, the variant of AthlonXP with the physically-smaller CPU core. It's visually different: comparison.

Notice the black label at the edge of the Palomino. You could peek under the edge of the heatsink and see if it's present.
