Repairing a GTX 560, GTX 580 and more GPU with heat gun and fix square artifacts

This tutorial is your last chance in repairing your broken GTX graphic card that got an overheat issue, before proceed with this tutorial please make sure that your problem is not a PSU, driver or any external problem of the graphic card.

The concept behind heating a GPU or Vram is simply to Reflow and Soldering some very small balls under the GPU or VRAM.

Commercial Electric circuit boars are made of SMT IC’s (Surface Mount Technology). These IC’s are soldered on the board by placing a layer of solder on the board, placing the ic’s and then passing the entire thing through a Oven or a hot air blower. The places of electrical contacts get attached, while the rest of the solder melts and flows away.

Over time, these electrical contacts may develop “HairLine Fractures or cracks” that are not visible to the naked eye. If any such crack disconnects a electrical line or a chip’s pin, then errors occur, depending on the place/chip on the board.

Graphic cards, and Laptop Motherboards are very prone to this, because of the stresses they take, but this can happen to any electrical item.

What you need:

• Heat Gun.
• Flux.
• Thermal past.
• time and patience.
