Accurate Temperatures?

[adamfelker]

Hi all. I recently installed MBM5 and was somewhat surprised to see the temperatures for my Athlon T'Bird 900: 23c idle and never goes above 30c. This is with a Vantec CCK6035 and a 30-something CFM Sunon fan. I don't think these temps are at all accurate. What do you think?

Sound pretty low, but what is the ambient temps in your room?

Sensor 1 isn't usually the CPU sensor (but it can be). You need to pick all the different sensors and use the high/low screen while running something that will load your CPU (SETI, Prime95, CPUBurn...etc.). The one that moves the most/fastest is your CPU sensor.

What motherboard do you have?

Looks like you've got a low-reading motherboard, which in combination with socket-thermistors makes for very inaccurate readings.

are the temperatures ur comp give u really accurate?? you no when u boot up?

I've got an MSI K7T Pro-2a, (KT133 chipset).

roncarter,

Accurate temperature readings:

Depends highly on how you're measuring temps... Whether you're in windows or the bios usually has no bearing on this... an inaccurate temp source will be inaccurate regardless of where you "read" the temp from. the overwhelming majority of amd motherboards range from bad to worse as far as temp readings. Socket-thermistors do not make for good/accurate readings. Even the motherboards that utilize the diode, such as the SOltek DRV5, do not actually show you the temps from the internal diode, rather with a socket-thermistor... One should really ask why they do this....


adamfelker,

that MSI board was really teh last "low-reading" MSI board... with later msi boards, the readings are both compensated more and from a better socket-thermistor location (misnomer ). So, no, the pro2a readings aren't accurate, they're actually very much on the low-side.

MikeWarrior2: Thanks for confirming what I'd expected. Any idea how far below the actual temperature these boards usually are?

 

[Mikewarrior2]

NP... IIRC, it was anywhere from 5-15C lower than projected "die" temperature... a lot of variables play into this, including CPU load, heatsink, etc...

But your temps are soo low that even if it were 15C off you're still fine

>are the temperatures ur comp give u really accurate??

the one thing I learned from the cpu Temp debate is that there is no difinitive answer or concensus to an accurate cpu temp reading.

The best way I have ever understood it was in this little known article over at Overclockers and just make sure you go on to page3.
