Kev has asked me a important question I need your help on. I am not a AMD expert. Heres what he emailed me:


I have an AMD Athlon 1Gz processor with Thermal Take
>Mini Super Orb (www.thermaltake.com) and with my case
>always open, the system run at 58C for processor and
>34C for chassis. I don't know that is high enough to
>damage processor or not. So I need your help by
>telling me what temperature your system is running
>now. More over did you use any special thermal
>compound or gel?

Thanx for helping Kev out
 
actually my T-bird 700 overclocked to 909Mhz is running at similar temps... with full load it's around 58C...

Therefore I would also like to know if that temp will damage the processor?
 
Depends on hte MB.. if its an a7v, no.

If its a kt7 with a UL or later bios, possible, but probably not.

If its another board, that temp is usually a big no no.

Can you explain a bit why there's a difference between those boards?

I personally have the Asus A7V? Why is the A7V fine while the others is a big no-no? Thanks!
 
Several things: With 1004 and later bios', coupled with Asus using their own chip for temp reading, they compensate the reading differently. Which is why you see Asus boards typically running quite a bit warmer than other ones(most socket-a boards use the VIA Southbrdige chip to read temps). If anything the Asus temps are more accurate than other boards(but still craptaculary for comparison purposes).

The KT7 UL and later bios also does some compensating in a effort to fix the poor temp readings. They add a +10 to the cpu temp reading. For a kt7, 55-60C is usally the cut-off range between stability and instability.

For other boards(notably, the MSI boards) who have thermistors(or smd-resistors) that don't touch cpu backside pcb, and also have no compensation, these MB's severely underread temp. Which is why you see a lot of MSI boards "running cooler" than comparable CPus with KT7s and A7Vs. So for an MSI board, the limit is usually 50C or so.

HOpe that isn't too confusing,

Mike:

Thanks for the detailed explanation! It's not too confusing at all!

You learn something new in these forums everyday... 🙂
 
that explains why my duron 650@1050 runs warmer than my bro-in-laws tbird 750@1050. My 41-49 compared to his 36-43. I am using a kt7-raid and he is using the MSI. Thanks for the info Mike I thought it was just something with my chip.
 
LilStevo,

No problem. You see that same type of thing on forums all the time, since the MSI boards "appear to run so cool".


Mike
 
I have an A7V133, and I also have a problem with my temps.
It's about 58C (idle) with the case closed...
I'm using a Tbird 900 (not overclocked yet) and an FOP32.
I haven't removed the thermal pad from the bottom of the heatsink.
Do you think this could be a problem? Should I replace it with thermal silicone or something else? Is it a normal or a high temprature for the particular system? (I know it's in spec, but it seems high....)

Thanks in advance.
 
It's the 1001C bios (it came with the board)
It's absolutely stable except with AGP 4x (turbo mode on via 4-in-1) and system temp is 30-40C (depends if case is open or not)
 
Then I wouldn't worry... I would add more case cooling if you are concerned about case temp, though, and that will help cool down the cpu a bit.


Mike
 
Yesterday I installed Sandra, and the CPU temp readings from sandra were 39C (open case) while the reading from ASUS probe was 53-54C. So, it is the program that compensates the readings of the probe.
That's all..
 
Sandra is almost always wrong... Sandra could very well be trying to read temps off the VIA southbrdige chip, something the A7V doesn't even try to do.
