the joke is, when i run this CPU with correct parameters (FSB166, Multi and
Vcore Auto), the temp also goes up to 51 C in BIOS, but there is no
shutdown. The CPU ist not locked and the Cooler is an AeroCool Deep Impact.
I use NanoTherm as paste. Here are some links

Very strange! I use a Vantec Aeroflow and Arctic Silver Ceramique on my
XP2500 / AN35N combination. Currently I'm running tests with the CPU
undervolted. Just finished a successful Prime95 run (207x10 vcore 1.55v} and
the MBM5 indcated temperature never goes over 44C. If I run at 220x10 vcore
1.75v the temperature would get up to 51C. The case I use is an Antec SX-835
(350watt Antec power supply) with 2 80mm exhaust fans and room temperature
varies between 24~26C.

I still think you've got a heat problem. Like I said try MBM5 for real time
temperature monitoring. 51C at stock settings is way too hot for "idle".

I think there is no heat problem. Same temperature with 2500+ parameters
(166MHz, the rest on optimal and auto) and no shutdown.
But i have seen, it is a new release of this board. There is a new feature
"CPU burning proof" which couldn't be disabled. I tried it with standard
parameters, only changing the multiplier from auto to 11,5. Yo man - 33
Seconds - shutdown - overheated. I tried a Thermalright SLK900A with a Titan
92mm Fan - 41 C - overheated - shutdown. rofl. I think Shuttle did a great
Job in turning a fine board to f...... shit.

Btw. Chieftec Midi Tower CS601
PS Enermax 365AX-VE (+3.3V: 32A, +5V: 32A, +12V: 26A)
4 x Enermax 80mm Fan (front: 2 / rear: 2)

I also tried it with my own CPU, a unlocked Barton 2500+ too, working fine
on my Leadtek as 3200+ with FSB 200 and 1.725 Vcore. The result on this
AN35N is the same. Shutdown.

Hi Frank,

you are right, there was a heat problem. But it wasn't the heat sink. I have
changed the board and now i am grtting 39 C while running in BIOS and no
shutdown.

Was the AN35N motherboard the cause of the overheating? That would be
strange, but I'm glad all is well now.
