1st best thing would've been not trying to power it on.

Measure for shorts, dremel the pcb out in that area a look if they're gone. Doesn't look like there are any traces you have to worry about.

it doesnot have traces there. i think it doesnot boot because of a short circuit on the last fan header pin.
can that be the problem?

I dont think it's only the pwm fan header pin, you have most likely connected multiple layers in there.

Just take a multimeter and check the pwm pin, 5v, 3.3v and 12v to ground

i am new to this stuff. but i know the basics. after the pwm fan header pin. what i should be do next? according to the location of the crack.

The board has 8 or more layers with traces (electrical paths). The break probably shorts some traces from different levels of the PCB.

Exactly this.

Usually you repair this by grinding away the PCB in this area, make sure the layers aren't connected anymore and if you're feeling fancy you cover it up with liquid soldermask afterwards.

what do you mean by connected multi layers? did you mean that the crack conected many things togather in the first layer. or the multilayers connected to each other.
if the multi layers connected. how i repair it?

after i am grinding away the PCB in this area and make sure the layers aren't connected anymore . if i have a trace may be in the 2nd or third layer how i connected again ?
if a trace is in 2nd or 3rd layer .could i see them ? because i dont see any trace there.

You start from the top to the bottom with grinding and just look if you find any traces while you go through. If you find something you need to figure out where it belongs with a multimeter, so you can solder the connection back together. But i'm not really concerned about alot of stuff going on in this area, you probabaly only have a few large copper layers.

But if you haven't done anything like that before, i really doubt that your sucessrate will be high. Especially if something's fryed because of the short.

I'd get a new board. You don't know how much that damaged in from the MB as well. After it is fixed, will you trust it? I'd get a new board and not waste the time and maybe the money if something shorts.

It is repairable. Did something very similar on a SM X10SRH CF

Since I find the explanations of the many before me rather good, correct and understandable, it seems as if might not be that able to do it and I won't recommend you to try fix it yourself.

On the other hand, I would be very interested in buying it from you in that condition, so that might also skew my recommendations ; )

what is the possibility of something fried due to the short ?

How dafuq should i know i don't have supermicros internal documents and know what exactly is in that area!

If you paid 600$ for a defective motherboard on ebay, i'll just hope God has mercy on your soul.

You seem to lack any knowledge whatsoever and probably also the right equipment. Do you seriously think i could do remote repair on a mainboard that has obviously a short through board???
