Temp probe

[Sub]

Ok with my w/c (even if by mistake) i got a temperature sensor probe thingamajig, anyhow it reads ambient accurate i guess..
and so i thought ok since i'm re-assembling the whole system (dont ask) i'll put it on the cpu, so i used some thermal tapey stuff and put it as close to the cpu die on my athlon as i could get it really. as i figured it's stupid putting it between core and block as thats stupid and i know you shouldn't really do that.
anyway
my board shows 22 amb 33 cpu and the temp sensor shows 26.6 (ish)
is there any possibility that this is accurate, and the mobo temp is WAY off.. or is the temp probe way off..? and should i take that as more or less water temperature?
i ask because i know the cpu temp sensor is under the chip in that little block thing gap uber the die.... thats a point.. how do 939 chips measure temperature? since theres no room for a probe underneath (sorry i have no idea where the probes are tbh just i can see myn on my mobo so thought i'd ask

cheers if you got this far :p

Sub is this a temp probe with two really tiny wires about 3cm long at the sensor end?

erm its like 2 little wires in a plastic sliver which is more or less about 3cm ish if i rememer rightly yea.

You just have to position the sensor as close to the core as you can without affecting the seating of the socket. Wherever you put it, it's not going to be 100% true reflection of the core temperature.

What motherboard are you running. I'd tend to rely more on the sensor reading that the bios reading. BIOS readings tend to not always be that accurate, and depending on your board theres known problems with a few boards that the temperatures are not accurate. My board(DFI nF3 250Gb) and a few other of the newer DFI boards have a known issue with the BIOS that the BIOS readings tend to be quite a bit higher than actual temperatures, there is a beta BIOS(which I am using) but DFI have not released an official uptdate

motherboard readings are known not always to be totally accurate.

i have read somewhere (i think it was micromart > they dont know too much i kno) and it said some pc programs can have errors as big as +/- 10 degrees!

but an example is that with my asus probe program, and old version said the cpu core was at 42 degrees, but when i upgraded it said 46, so they aint accurate!

me thinks cpu cores shud have onchip thermo sensors as in the gpus to give accurate readings

yea i mean it's like taped to the bit next to the core so i imagine thats as close as it gets tbh... ive got an
MSI K7N2 Delta, any problems with this? i know when i had my kt4av board that the temp was more "stable" as in it only went up and down a single degree at a time as it got hotter, and it stayed at one temp, but on this k7n2 the temp reading fluctuates all over the damn place.. like 32 35 32 33 32 37 32 32 33... it gets that bad.. and then when i load it out it used to (b4 water) go like 45 48 52 46 48 47 47 48 49 53 50 51.. within a 50 ms time of the reading, even on a 1 second gap reading it jumps all over the damn place on a graph the spikes are daft.

i'll just get a jpeg of it and i'll post what i mean in picture format might be easier to understand since i probably made no sense at all there

k pic of the output over like a few minutes... see what i mean about the cpu temp...

bumpage...

[muddyfox470]

if these readings you are talking about are from your own temperature probe, they will just be because of the temp probe itself, they are not gonna be perfect and the reading will never be 100%, its not jumping that much, so i would have no major reason to complain!

they are from the motherboard sensor. temp probe is a little screen...
