Heres the story,
Brought a YLod ps3, When the power button was pressed 3 beeps and a quick flash of the power light, reflowed it using proper methods no hair driers and other junk, It now boots to dash and can use games, watch br etc, but the fans ramp up really quick, so stripped it down checked where the new heatsink compound was on both the chips and the heatsinks getting a full face to face patten, tried again getting fast fans, brought two copper shims to go between the faces, re-compounded all faces and rebuilt, same results.
It's my first ps3 i've had the pleasure to play with so have i missed anything ?
checked the heatsink pad on the south bridge that is touching the mating faces and have renewed the pads on the four little chips that go on their own little heat sinks.
Tried another reflow just incase, made no difference.
They air blowing out the rear is not warm so its no too hot.
I'm thinking the chips heatspreader the metal part bonded to the chip, this must not be contacting the chip correctly.
Think i'll stick to xboxes, I know the idiosyncrasy on them.
