WebMar 1, 2012 · The Solutions: Reflow Method Repair - A reflow repair is when the system is taken apart, down to the bare motherboard. The GPU chip is then subjected to heating temperatures of about 300-450 degrees. The high heat is necessary for the solder points underneath the chip to become liquid so that it remolds back into place.
