NF7 series users...... My temps are freaked up. Help

~~DriveEuro~~ · Apr 16, 2003, 11:34 AM

So here we go... Yesturday the temps in my city were 80F. My CPU was at 52C full stress. Ambient was 25C. Night time came and our temps in the city dropped to 40F (damn Chicago weather) and my CPU dropped to 42C (with my window barely cracked)... Now this morning my window has been closed for quite some time (1-2 hours) and my temps are hovering around 46C. The problem is that this is with an ambient temp of 24C in the room? WTF. My CPU temps should be this low.. They just miraculously dropped 4C of what they were two weeks ago under the same conditions. Is there something freaked up the the NF7-S temp sensor where it likes to start reading accurately? I mean, this temperature is what it really should be.. Anyone get my drift?

can you post up these things:
1. idle cpu temp
2. idle mobo temp
3. load cpu temp
4. load mobo temp
5. ambient temp

maybe take these readings at 80F and at 40F.

and my v1.2 has been the same since I bought it... 43c idle and 48c full load. has not fluctuated. Even when it was 93F outside I still sat at 44 and 49. Taking into consideration my +7c reading I'm tickled pink

But really, you should not be getting any 10c variations liek that..... help us out with the requested readings when you get a chance..

Eh, well, the thing is the ambient temps (from the temp sensor to the right of the CPU) read 24-25C.... Today the temp in my house is more like 66-68F yesturday it was like 77-82F. Could that be the culprit? Just the fact that it was 40F hotter yesturday? It's just odd cuz my ambient temps have not changed. It's almost like I don't have that 7C skew anymore... Ya know?

but if your room temp stays basically the same, your pc temps *should* stay basically the same too!!! I mean who cares what the outside temp is if your ambient PC room temp is the same!! but first thing, stick up those temps m8..

~~DriveEuro~~ · Apr 16, 2003, 01:41 PM

I have to go to work in like 2 minutes... But hey, room temp is the same........ but why was my temp at 52C yesturday and just 46C now? get what I mean? Well, I'll get back to this in 5 hours after work.

man, listen, we can not go any further (at least I can't but maybe someone else can/will step up) until you post up for me the 5 temperatures from above.....

Stressed
CPU = 44
Ambient (sensor to the right of the CPU socket) = 22

Unstressed
CPU = 40
Ambient (sensor to the right of the CPU socket) = 21

House temps
Thermostat in the house is set to 68F (20C)
but my room is more like 70F so it's 21.111C

Outside temp is 42F (5.555C) and it's not like i can take temps at 80F cuz the weather isn't 80F

OK its a good start. Ambient temp is your room temp not any temp sensor inside pc.

so we have:
1. 40
2. 21
3. 44
4. 22
5. 21

Now you have some REALLY good airflow if your mobo temp is the same as ambient temp!! (which is just another name for temp of room). Right now my ambient (room) temp is 22, my mobo temp is 23 and my cpu is 43 - the 7c nf7 thing = 36. Thats 13c above my mobo temp and still a bit high. Generally we want cpu to be 8~10 above mobo temp (which it was on kx7 just not on this crazy nf7..

). Anyhow, your gap between mobo temp and cpu temp is better than mine by 1c! I have a 20c difference (which is NUTS

) and yours is 19c diff (though we take into account the 7c high reading at least and gives us a much better gap).

now to answer your question about the temps... only a couple things I can think of:
1. you have a variable fan on the hs that was down. or maybe an automatic fan that was running slow all night and the cpu just idled high.
2. I had thought maybe it was your airflow but obviously thats good! though next time you see 52c cpu, take note of the mobo temp as well
3. when it was 52c, ambient temp was 25c. and now at 21c you say cpu is 44c. so all things being equal, at 25c ambient you should have been at 48c not 52. Again, if you see 52 again, take note of the mobo temp (sensor right next to cpu). I still think it may be an airflow problem but we won't know until it hits 25c ambient again

Ha, right now it is 44C with case temp of 43C.
3)....When it was 52C the temp outside the house were 80F+........
1) my smart fan 2 is set by potentiometer at 4200rpm.

Euro, you using motherboard monitor 5 to get the temps?? Go with that! Sensor 1 and sensor 2. 2 is cpu and 1 is mobo if I remember correctly. And NO WAY your mobo temps can be 21c idle and now a few hours later 43c!!! set up mbm 5 and lets see what we get

I have a NF7-S v1.2 and my CPU temps are about 38'C with the case open and about 42'C with it closed (i need case fans!) SO does the above statement mean that the NF7-S reads temps 7'C too high? If so my cpus at 31'C??

SOme clarification on this would be parreciated and is there anyway to make the NF7-S read correctly??

I use both winbond and mbm5, and the BIOS to check temps, all seem pretty much the same as each other.

P.S. Winbond now causes my CPU fan to stop, i dont' use ti anymore.

shuki · Apr 17, 2003, 06:14 AM

not to get too far highjacked here but.... yeah, the nf7-s boards (and possible the nf7 non s as well...?) are at least 7c too high. I went same setup only changing mobo and got a 7c rise in temps.

what BIOS you using? I know this 7c is with the 16 BIOS not sure about previous BIOS'.

to correct the problem in mbm 5 just open up temperatures, select sensor that you have going with cpu sensor and scroll down under alarm side until you get to compensation for this sensor. set it -7 for a more accurate reading....

Schtopper · Apr 17, 2003, 06:33 AM

OK ta.
Just curious but what evidence do you have that this is a genuine error? Other than going from one motherbaord ot the other, have Abit admitted it? Only reason i ask is that i noticed the same sort of increase going from my KX7-333 to the NF7-S but what i also noticed is that in the NF7-S the sensor under the CPU touches the bottom of the CPU but in the KX7-333 its bent horizontal and doesn't quite touch the underneath of the CPU. Therefore the KX7-333 is only reading the surroundign air under the CPU and the NF7-S is reading the actual CPU bottom.
I hope it is a genuine error as i do find the CPU temp to be a little too high in comparison to system temp or ambient temp.

shuki · Apr 17, 2003, 07:35 AM

just head over to abit forums or amdforums (abit mobo section) and read up on it. you'll see that everyone that has upgraded to this board had a marked temp increase. whether all previous mobos just measured wrong or not, I'm sticking with everyone else on this one and saying nf7 is high.... others contend that all previous mobos measured low. really just whatever you prefer m8...

Schtopper · Apr 17, 2003, 08:02 AM

Cool. I have heard the NF7-S may be getting its temps from the on-die Diode. If this is the case then i would imagine the NF7-S recordings are more acurate than previous boards that use an on-board sensor. It would also explain why it shows temps higher than normal.
Who knows, I might add the -7 compensation just to make me feel better
