Need An Expert Who Knows ASUS P3B-F Boards.

OK its not a rush but i need someone who has a board like that or other ASUS mobo what has a similar design. First of all if someone could tell me where (if possible) i can connect a fan to the mobo so it uses the power from the board to cool down the case inside. Secondly where is the temp sensor located for both the processor and the insides of the case (accorording to MBM 4, the prcessor's temp {higher#} is 56-61C!) I need to bring that down and the only thing i can think of is to replace the cooling system on the processor with a heatshink/dual fan combo. Im not ready to do that so i want a fan inside the damn case to cool it down better but i have not enough power cables and my last one will go to a new CD-RW. Is there a way to branch out alredy existing cables from the PS for more devises to be hooked up, small ones like fans. Im thinking of made connections like from Radio Shack, nothing home made (dont have nerves for that )
I have only 2 fans.. PS and proseccor and although everything is all spanking stable i want to bring down the heat cuz im thinking of overclocking to 600-650mhz max. Need help, so if someone with ideas and a P3B-f mobo manual has any that would be greatly appreciated.

So again the question is: How do i cool down the comp inside and the processor using fans on a 250W PS with no cables to spare.

PS: i already remuved all the PCI slot covers from the back of the comp to allow more air movement but that does jack...unless that MBM4 program is crap.

AGAIN thx to ALL of u!

Hello Toxic,
Ideal processor temps should run 30C or lower on a properly configured machine. Case cooling plays an important role, as you suggest.
I am not really a fan (pun intended) of attaching chassis fans to mb pinouts. Amperage overdraw will quickly burn those out and render them useless. Better to save it for a second processor fan.
Get a couple of 80mm case fans with pass through four pin connectors and you will not have a problem with running out of hookups. Personally, I shy away from tying into voltage to hard drives and use the cable to the cd rom if necessary.
Your temp is so high that I would question the integrity of the processor-heatsink interface. The efficiency of the fan may also be affected by a buildup of dust, same goes for the heatsink fins. Thus, a good cleanup may be in order.
Ambient temp is a consideration also, I keep my computer room @70F year round. I expect my case temps to run no more than ten degrees above ambient. Many folks strive to obtain temps equal to ambient in the case.
The P3b-f utilizes the on die thermal diode for temp measurement of the processor. I cannot tell you where on the m/b the chassis temp is taken.
Concerning mbm 4- as far as I know, it's ok. I use the Asus probe utility. It came with the board.
The manual for your board may be d/l from the Asus website.
Hope this is a help to ya

okay I have an Asus P3B-F (used to be in this comp) so I know it pretty well.
the fan headers are white, 3 pin, and are marked, cpufan, pwrfan and chafan i believe (chassis fan)
they're hard to miss

and also, the board uses the CPU for the thermal diode, Intel CPU's for i dunno how long have onboard thermal diodes so it gets their temp from there.
the temp reading you have of over 60C at times is probably false if you have BIOS 1004 or before
if you go on the asus site and go into the bios section of the P3B-F
there is a bios fix for the improper temp reading of that board. my CPU would always be in the 40's with my golden orb, 80MM fan blowing right onto my CPU and arctic silver paste to help
NOW it's at 30C on my 6BA+IV (same voltage) so it proved right away the temp reading is off.
hope this helps you out.
