2500@3200 or the last time I?ll believe a temp reading

[nimo]

Well to make a long story short my 2500+ at 2500 was running at 48C idle

I took a gamble and OCed it to 3200 to my surprise the temp reading is now 48/49 idle
I loaded prime95 and ran it for a few hours the load temp went up to 57C
with no errors.


Are temp ?gages? that unreliable?

It's not that they're unreliable, it's just that some people are very anal about low temps. If it's below whatever AMD recommends (I think it's around 85C) and it's stable, don't worry about it.

The problem is that there is no standard set for readings. Motherboard manufacturers often use different thermistors sometimes placed in different places and different algorithms to compute the temperature. Even within certain boards, the bios can have an effect on the measured temperature. The NF7-S was notorious for reading hot, but after a bios change, temperatures were miraculously lower! Then again they were raised! It's not so much that some people believe that anything over 50C is dangerous, but they're just hedging on the side of caution.

There was a board that actually read from the thermal diode on AMD chips, but it was so high compared to other boards that the manufacturer abandoned the accurate reading and "lowered" temperatures drastically.

We can dream when boards will not be judged by the reading of their thermistors but of the trueness of their reporting.

Anecdotally speaking, I have heard from others that you need to add at least 10 degrees to whatever your bios/mbm is giving you (sometimes as much as 20), to get more of an accurate idea of what the temp actually is. Personally, anything over 48 scares me.

...or subtract 10-15 in Abits case...

is that really really true. i would like to know the "real" temp of my computer but i always read that the ABIT report low and it's always different.

short of installing quality thermomter in a place i don't know .. what's the best way to know the real numbers?

if i subtracted 10-15C from my current temps i'd be at

22-27C CPU
9-14C system

those seem a bit too low but i wouldn't care anyhow. if it is true, then the Sonata is pretty good for cooling.

It varies from mobo to mobo. I've tried letting the winter air into the room and the temps are about 40c with a SLK and a panaflo 48Cfm in my pc with the case open. I gave up trying to conform to the crowd that believe temps are everything.

me too. but i just wanted to know the truth behind "abit mobos report lower temps"

If the computer restarts, then its overheating...
Otherwise you should be fine.

As a rule, the actual core temp is anywhere from 5-10 degrees C higher than the socket temp. That's assuming the socket temp sensor is reporting the correct temperate at the socket. I'm pretty sure all new motherboards are capable of reading diode temps from inside the core, so just go by that.

85C is way too high from what I've read. I believe 60C is where you start to worry.

I've heard that as well. Had an ASUS A7V that reported near 50C, but with the same innards running on an Abit KX7333, then KD7 and now an NF7, my temps dropped to the 30's or low 40's. I gave it the feel test and the base of the HS was only slightly warmer than the rest of the case. Actually, I had to touch it in several places just to confirm that it was pulling heat from the cpu. It almost wasn't even warm from what I could tell.

I have no idea what the true temp is but it reports cool, feels cool, and is 100% stable so I just quit wondering about it. I'm on my third Abit board and the temps have been the same as the one before.

woa scary.. i just opened up aida to check on my temps, clicked on sensor, looked down at cpu diode.. 111C!!!!! my brain goes "whaaaaaaaa?!??!!" then it refreshes itself and reads 43C.. phew! safe... although there is a funny burning smell

Nope... AMD says their processor will operate up to 85 degrees C without a problem.
