Asus P5B-Deluxe and INSANE temps

[casual7y]

hi all,

So before i start overclocking, i fired up speedfan to check out my stock temps and i was quite surprised, as everything looks normal, except for one temp.

*These temps are at idle

this has been bugging me for a few months now, and has stopped me from overclocking, but my computer has been running fine since christmas, since i got the board. and i am on stock cooling, as well.

My specs are as follows:
Intel Core 2 Duo E6400
Asus P5B-Deluxe/WiFi
2gb DDR2-800 OCZ RAM
GeForce 7900GT

I dont think i have a defective board because my friend has an identical rig except his video card is a 7800GTX and he uses a scythe ninja rev B tower, and yet he also gets an AUX value of over 90C.

The only thing i can think of is my Videocard, since it's fan sounds liek its about to crap out (its making really loud noises and sometimes takes a minute of two to start up when i turn on my computer)

EDIT1: yet dispite the high temp warning, my friend has been able to Overclock to over 3.2 Ghz on his rig. Ive been able to get to about 2.66Ghz but then i chickened out because i didnt want to risk hurting my computer.

EDIT2: Ive also touched the northbridge/south bridge heatsinks, as well as the CPU and video card heatsinks and none of them seem especially hot. so i dont think any part of my computer really is 100C...

I'm had the same situation as you. Speedfan showing 119C on the AUX temp module. I too am on an P5B-Deluxe/WiFi with e6600. I just ignored it. I am running Vista 64 and I just figured it got mixed up on the addresses or something.

lol well i'm running 32bit XP SP2 and it's still doing that. (I'm using a vista-wannabe skin)

It might be a bug with speedfan, although ive used speedfan 4.30, 4.31 and 4.32 and have always had this problem.

Not to scare you, but I went through 3 P5B Deluxes, the first two both went bad while doing a "minor" overclock of an E6600 to 3.2Ghz, something that most people seem to think is easily attainable with this chip and a good motherboard like the P5B Deluxe.

Two things stood out as problems:

1. When the board is mounted in the case, if the board flexes too much because it does not fit perfectly in the case or whatever -- there is a chance that the heatpipe will not touch properly anymore. This usually happens in the upper left hand corner area. If this is the case, temps for the mosfets may reach very high levels and could overheat -- especially when increasing voltage in the system.

2. The P5B Deluxe voltages when set to "auto" will automatically increase as you increase your overclock, to help with stability. I always assumed "auto" meant don't increase the voltage past stock, but this isn't the case with the P5B Deluxe.

Combine #1, and #2, and you increase your chances of damaging your P5B Deluxe because of the mosfets becoming much hotter when you increase voltage and poor contact with the heatpipe.

Just be sure when overclocking to set your voltages manually to their stock settings and only increase them if necessary and you should be fine. I'd also recommend using the "optional" fan that comes with the P5B Deluxe for the mosfet portion of the heatpipe, unless you have a better fan already dedicated to that heatsink.

I'm not sure if the temp reading you're getting for the AUX is accurate or not, I ended up getting rid of the P5B Deluxe after 2 bad ones but just be careful! This is the first time I've had any sort of hardware failure while attempting to overclock.
