Im new to xbox360 moding, first off, would soldering on a 'piggy backed' sst bios chip to the dvd drive with a 15 watt iron fry the chips? My computers teaher says it will, But I disagree with him, and second, im going to install water cooling and I was wondering if there was a safe 12v source on the motherboard that would power a pump and 2 120mm fans.

Watercooling should be powered by a external source.
And why would you use the modchip. The firmware hack is Waay better.

I am fully internaly cooling my xbox 360 too and what i am going to do is use the power cable from the dvd drive and slice into that and hook the positives and negative 12v source up to power my pump, i know which wires to use on the dvd power cord from this great pdf i found. Then i am going to use two 6v 80mm fans to cool a dual 80mm radiator(i may decide though to use 12v fans), to power the fans i am going to sodder onto the mother board at this juncture

. And use the existing fan plug from the stock dual 60mm fans. (You need to use that juncture if you are running 12v fans because the plug for the stock fans has peak of 12v and idel at 6v. When i used me volt meter to check it, that point put out 12v continuosly no matter if the system was idel or playing a game or watching a hd dvd. Also i used that same pdf to look at that juncture and found out that the ampage will be able to handle the pull from at least two 80mm fans. I strongly dont recomend drawing all your power from just one of either the ways just mentioned. For this will most likely result in you frying your mother board at the connection points or less seriously just preventing a component from not funstioning how it should. But Im going with that youll fry something if you do that though.

Yes, your teacher is an idiot. How does he think those chips were soldered onto the board? Obviously not with an iron but heat is definetly involved. Components like that can usually withstand like 200'C for a few minutes and then it potentially fries the chip. There is no way that your 15w iron will fully heat the tsop to that point and cause damage. I did all my desoldering and resoldering of NAND's (360's tsop) with a 25w iron and didnt do any damage. Ask him what his basis for that statment is...
