I recently upgraded my motherboard, currently i am running a Barton 2500 XP, 1gb kit of of Corsair 3200ddr and a Shuttle AN35N Ultra. MBM5 is giving me a temperature of 29C idle, about 41C under load and 26C as Case temperature. Temperature readings seems to be a bit too low for a CPU that is clocked at 2.2ghz (11X200).
I also checked in the "PC Health Status" section in the BIOS and found the same readings...
Is my mobo giving me false readings?

Thanks.....

Yeah. Keeping a 5-gram object at 41C with air cooling when it's generating about 70 watts of heat would take a heck of a cooling apparatus. It's probably somewhere closer to 65C-70C but don't let it bug you.

To put it into perspective, imagine wrapping your hand around a 75-watt lightbulb and switching it on. Your temperature is 35C initially... think it's going to top out at 41C? ;) Uhhh... no. You'll be letting go within five seconds. When you think about it, it's surprising that air cooling can keep that tiny CPU core down even to 70C, let alone 40C, considering the tiny contact surface available for the heat to be transferred to the heatsink.

Thanks for the reply mechBgon. Are there any other AN35N Ultra users out there experiencing the same thing ? Also, is there any known fix for it?

This will give you a good read on your temps, better than MBM IMO.

AIDA32 reports 52 C @1.7V with 97% load as I run F@H 24/7 on my AN35 Ultra 2500+ Barton. SK-6 w/ 7k Delta. MBM reports 49 C on the same rig.

AIDA32 reports 54 C @1.7V with 100% load F@H 24/7 on my Asus A7N8X Dlx with 2500+ Barton. Retail HSF. MBM reports 57 C on the same rig.

Abit NF7-S rev 1.2 here, with Tbred 2100@2.2GHz.
AIDA 32 reports:
47C CPU, 32C case

MBM5 reports:
47C CPU, 32C case
Even the voltages match.
:confused:

AIDA32 is giving me the same readings :( :confused: So is there another way to find out what my real system
temperatures are? MBM5 and AIDA32 are giving me the same results.

My System:

2500XP barton OC'd @2.2ghz (11x200) using stock HSF
AN35N Ultra (like the title says :) )
2 sticks of 512mb Corsair DDR 3200
ati 9500 pro

right at this very moment my temps are:

AIDA32
32 C MB
33 C CPU
29 C Aux

MBM5
32 C Case
33 C CPU

A couple of weeks ago I used an XP1800 with the same board using a Speeze Falcon Rock and have never recorded a cpu temp above 35C even under SETI. According to what I read at this site the2500 Barton has a typical power dissipation of 57.3W and 68.3W max. It *should* be running warmer than it shows but after hours of use I gave it the touch test and the HS and socket were just barely warmer than the rest of the hardware. My conclusion: I'm still not sure that I believe what I see but I know that it runs cooler than I expected. Overall it's been a very nice board so far. I don't fully trust the temp sensor, but I tried AIDA and got the same numbers. I know it's running cool and and solid as a stone so I gave up trying to figure it out. It's my first Shuttle board and so far I'm pretty happy with it.

My XP2400 \ NF7 stays near 40C using an SLK800.
