XP 1800 at 50C without playing games..???

GEShields · Dec 6, 2001

I just put together my Asus A7V266A with the Athlon 1800 and an SK6 with sunon fan (blowing onto HS). I have Artic Silver 1 (NOT 2) applied to the HSF and cpu as per their instructions and the cpu temp starts at about 33C and starts to climb and then stays around 50-55 without playing games or pushing it. Just surfing the net, etc.

I want independent confirmation of this so where do I get Motherboard Monitor from? And also, should I be concerned?

it depends if you are stable or not. the core can handle up to 90 C. of course the temps are off and don't reflect the core temp accurately.

GEShields · Dec 6, 2001

So far everything has been stable..up and running now for about 5 hours...

Mikewarrior2 · Dec 6, 2001

Which jumper setting are you using with teh A7V266e? The T-bird/duron or REserved?

What's your case cooling like, and how's your case temp?

I thought it was 60 C. I know that's what it was for Thunderbirds and Durons (Spitfire).

No, AMD max "DIE" temps are 90-95C for t-birds/durons depending on the speed. THe problem is, Very few mbs read DIE temp.

sorry about using the word core instead of die. my bad.

If its stable...i say don't bother. 50C idle still OK.

Thats a pretty horrible temp IMO, but it could just be your mobo reporting a inacurate temp. My stays in the low 30C's with a pretty poor HSF but good ventalation. Try reinstalling the hsf, you may have bad contact with your thermal paste or something

I have already reinstalled HSF. Same. Case ventilation is a stock Lian Li Case with 2 80MM input fans lower front set to high. Enermax PSU fan and 1 80MM exhaust fan..

Case temp is around 78F-81F

Asus monitor is notorious for giving temp readings of 10 C over real temp. Get a third party harware monitor if you're worried, but if you are stable then let it go. You might also uninstall the Asus monitor software as it can be problematic if it becomes corrupt. Good luck -

"Thats a pretty horrible temp IMO, but it could just be your mobo reporting a inacurate temp"

what i find unusual is that it is generally accepeted that mboards that show lower temps are more accurate. this may be true, but it seems very possible that the boards that report higher temps are actually more accurate also. The latter seems like it would be a safer approach IMO, since the cpu can't be too cool.

Mikewarrior2 · Dec 9, 2001

Lower reading mb's should not be regarded as more accurate. SOcket-thermistor's under-read temperature, period. Looking at internal diode tests, there are times that even a mb like the kt7(with a thermistor that contacts cpu backside) still underreads by 40% of rise over ambient difference.

That being said, different mbs can read vastly different temps due to thermistor placement/heatsink/ambient case temp/bios compensation measures...

The Asus motherboards use a different method of temperature reading. I think they either read the core and give the temp, or for some reason they add 10-20 degrees celsius to the temps :Q

My friend just got an A7V266A-E and it reads his AXP 1600+ @ 60C idling in BIOS

Mikewarrior2 · Dec 9, 2001

the a7v266e doesn't read the core temp... yet....

Its important to realize that BIOS temps are neither idle or full load...

My A7V266-E + Athlon XP 1.4GHz + SK-6 reads 63C under load (Prime95), which has caused me to think that I should re-seat the HSF despite my initial visual confirmation that the SK-6 is making good contact with the CPU. Case temp is around 30C. Ambient is in the upper 20s C.

It is reassuring to see that others have reported such "high" temperatures and that it doesn't appear that I'm close to frying my Athlon.

Suggestion to Anandtech: come up with a chart to allow conversion of various CPU temps for the different motherboards.

Example:
Baseline: Athlon XP on-die 30C = Asus A7V266-E 60C = Epox 8KHA+ 40C
Increase/Decrease 1C for Athlon XP on-die = 1.1C Asus A7V266-E = 1.25C Epox 8KHA+
or something like this

Is this feasible? I'm not sure, but no doubt it would require extensive testing and lots of empirical work. I don't know what such a study would accomplish or if it would be worth the time involved, but it would be interesting to read.

My system:
ASUS A7V266-E
Athlon XP 1600+
Thermalright SK6 w/Sunon fan
512 MB Mushkin 2100 DDR CAS2 (256M x 2 = 512M)
Voodoo5 5500 PCI
Soundblaster Audigy
3Com 3C905B
Adaptec 2930
Kenwood 52X Zen CD-ROM (SCSI)
Yamaha CD-RW (SCSI)
2x Seagate ST320414A (20GB 7200 rpm) in RAID 0 array
Iomega Zip Drive
Superpower KS298 mid-tower case
PC Power & Cooling Silencer 400 ATX PSU

Gandalf90125,

That is near impossible to do.... First off, every socket-thermistor/heatsink combination behave differently. Cross-MB "semi-direct" comparisons are impossible due this issue.

IN addition, iN terms of actual DIE temp change, you'd look at a7v266E = .75C; 8kha+ =.65C; K7tPro266 = .5C versus every C the die changes. Socket-thermistors report less change, not more.

For a good quote, see this article:

Overclockers.com Heatsink Comparison

Particularly, pay attention to this quote: Last, remember that in-socket thermistors are not accurate measures of CPU temps. Every heatsink affects an in-socket thermistor differently, as does airflow over the motherboard. There is no consistency between motherboards as well. At a minimum, you can factor +/- 5 C to these temps.

However, I'd stretch the +-5C even further. IN most MB's, you're looking at least +5-10C, and in certain cases, +20-30C aren't uncommon (requires certain combination of heatsink + mb).

Lost Circuits also reports a higher than "average" temperature reading from the A7V266-E.

To summarize: He found the idle temperature to be 50C on the Asus board, whereas the same CPU/HSF combination came in at 35C on Epox, MSI, and Shuttle.

Mikewarrior2 · Dec 11, 2001

he *shouldn't* be getting 35C for the shuttle, epox and MSI...each reads temps a bit differently.

Does that mean that my ASUS CUSL2-C and TUSL2-C that both show 31 C for a full load with a 900@1008 in one and 933@1050 is really running at ~21C?

alee25 · Dec 11, 2001

im getting about 45C with an xp 1700 just on idle, using internet etc, havent really checked while playing a game though. My system seems to be pretty sable though, never really crashed yet. Im using an EPOX 8kha+.

I used to have a delta fan on the heatsink (went around 7000-8000 cpm) but it was way way too loud, so i switched it off with a stock heatsink that goes arbou 4000cpm. I think its a bit high, but im not worrying.
