Hi guys , my friend has asked me to take a look at his console as it was over heating , turns out the fan no longer works , ive tried anther fan and that doesnt work , the jtag thing he had done by someone on ebay has never worked from day one not sure what he was on about but he said when he had it back he had to put a code in and he did it wrong and wouldnt work from then on ? Anyways would the wiring for the jtag have any thing to do with this ? and can i rewire the fan else where ?

thanks
