i jus transplanted my motherboard, and its all working great other then the horrendous noise i hear now, the fans going about like maniacs, and also, the floppy drive isnt working with the light remaining on :(
it was a compaq 6263EA, upgraded sound card (Audigy) and graphix ( ati radeon 9800pro) and jus transplanted the motherboard with a ASUS P4R800VM....
i did have some problem attaching the fan on the heatsink on the processor, had to literally force it down to click into place, though unsure which fan is makin all that noise...any help or ideas to combat this noise are really needed

Open case, unplug floppy cable, and turn it around(and end with twist in it should be on floppy side). MIght take a coupla tries if you have to swap ends(ie if end with twist is atttached to motherboard right now).

For fans, while it's not best idea, I will takeside off of case(with computer off obviously), take a screwdriver or similar and put it in blades of first fan to hold it still, turn on computer, see if it still makes noise(if it makes noise, that's not the fan that was making noise), turn off quickly, as it's not particularly good for fan to have it trying to run with screwdriver stuck in there, and then repeat until you find fan making noise. I'd guess CPU fan(due to mproblems you mentioned installing it) or a cable of some sort(most likely power) hanging in a fan's blades are most likely causes of your noise problem

About the floppy!

1.) You know how, when you look at the back of your CD-ROM drive or hard drive, Pin1 (the side you'd allign the red stripe of the cable to) is on the right? Well, surprize surprize, for floppy's, it's on the LEFT!
2.) You know how some cables have external keys, and the key always faces up on your CD-ROM and hard drive? On a floppy, the key faces DOWN, and there's usually nothing to prevent you from putting it on the wrong way!
3.) Of course, most MOTHERBOARDS put Pin1 in the same orientation for all drives, just to confuse you when you get to the other end of the cable
4.) The center part of a floppy cable's ribbon is flipped at one end. That's the end you plug into the drive.
5.) A lot of guys argue about it, but in the end, the only way the floppy light stays on all the time is if one or both ends of the cable are reversed.

well, its working now (the floppy drive) had the wire the wrong way round :P

both the CPU and chasis fans are louder then usual, the chasis one being the one with the most noise coming from, and it with the air they're giving out, i think they're blowing as fast as they can, any way to sort this? or should i go and have some new ones installed by some one who knows what he's doin :P

Asus Probes tellin me:
Temp CPU: 31C/87F Motherboard: 22C/71F
Fan RPM CPU: 5445 Chasis: 3461
^^ is that good or bad?

Did you check to make sure there is nothing in the fan or touching the blades? I'd had times where i'd have a sata cable be touching a fan and it make a terribly loud noice. Try unplugging one fan at a time it you eliminate the ones that aren't causing noise. Or you could just have your fan speed set higher now. Maybe since it was once a compaq it may of had some form of fan control built in.

Does your mother board support asus Q-FAN?
If its disable enable it might help.
If its enable why not try to disable it.
QFAN is suppose to regulate your fan speed to reduce noise when cpu is not warm...
If its not enable it should help if it is it might be [-peep-]...
Also if you have a PSU like ANTEC that got some technology to reduce fan speed + QFAN it might give some weird results.

I should have asked first but is the sound only cuz the fan rev realy fast(my cpu fan is running at 3300RPM....)Or like if something is touching the fan?)

The pin 1 end of a cable is the end that is always oriented closest to a device's power connector, be it a floppy drive, hard drive, motherboard, anything. Applies to all cables, floppy cables, IDE cables, fan headers, PC case speaker connector, USB headers. That's the convention anyway.

Completely WRONG! Pin 1 is ALWAYS on the left as you face the rear of a Floppy drive. THERE IS NO CONVENTION! Panasonic floppy drives for example have the POWER connector on the RIGHT side of the drive, but Pin1 is still on left. Mitsumi drives often have the power pins ABOVE the floppy connector, but closer to the right side of that connector, and Pin1 is still on the left.

Don't repeat someone else's assumptions, THINK for yourself, OBSERVE what you find, you'll see that MYTHS do nothing to help anyone.

Panasonic drives, for example, are VERY COMMON and don't follow YOUR convention.

Oh, and to make matters worse, some Sony drives weren't notched for externally keyed cables, so you couldn't put the cable on properly if it had a key!

Your old board probably had fan speed control, you new one does too, but I'm not sure if it will work with your fans. You should try setting that up in BIOS.

If that doesn't do it for you, you could get slower fans, I prefer Panaflow's low speed fans. Or you could get one of those fancy Fanbus controllers Tom's keeps reviewing.

yup, asus did have that Q fan thingy in the bios, enabled it wid a ratio of 12/16 to keep fan noise low, is working nicely now, might go and buy some really quite yet cool fans as im gonna playing alot of games now...for now, all is good :)

That's a big OOPS! SORRY EVERYONE!

I never looked that carefully at floppy drives. I don't mean I was careless when installing floppy cables (OK a handful of times) but I mean I never really noticed that they don't follow the "convention".

Honest, I never witnessed it not working. I've been trusting that idea for 20+ years since an engineer told me that electronics are always designed that way, pin 1 toward the power supply. He wasn't a computer engineer though.

I guess I'm lucky that inverting floppy connectors doesn't hurt anything.

It's a widely held myth about drive cables as well, so widely held I've heard of it appearing in actual textbooks! Now, try telling a guy that YOU know more than the 3 doctoral grads who wrote his textbook, it's infuriating!
