Hi All,
Here’s the story. I bought an AMD Radeon R9 290 video card which was very loud with the fan turned on, so I tried to change the default factory fan with an aftermarket Accelero Xtreme III. After changing the fan when I boot the computer the video card fried. Analyzing the card it seems that the piece which broke was an IRF6811 component from International Rectifier. You can see why I suspect this particular piece due to the following picture showing how smoke came out of it:
As this card was about 400 EUR I thought it is okay to try and fix it by replacing the piece, which is a power MOSFET. I ordered the piece and here’s how it looks like:
And this is the piece to be replaced:
The tools I have is a Weller WESD51, solder Multicore Sn62 0.46 mm from Multicore or 60/40 0.6 mm solder from Super Solder Wire, and the following Weller tips:
I don’t have big expectations in trying to fix this but I though it worth a shot.
I do have the following questions:
1. How to remove the old piece from the board? As you can see it is soldered underneath the piece itself.
2. What temperature to fix the Weller tip?
3. Which tip to use?
Thanks,
Codrut
