Ya, I know how to take care of electronic devices.
I'm a programmer in the embedded world so ya
I bought my PS3 in nov. 2007. my 1st PS3 was making alot of noise (really inane) and it died after 11 days due to an firmware update. It stopped reading discs. I had warranty so got a new one right away. That one worked untill march 2010. That's when I got my 1st YLOD. Didn't have warranty anymore so i decided to have a go myself since I have some knowledge myself.
The PS3 has always been vertically and placed in an open area. I must say I started using the built-in Wifi since 2010 (used a wired connection/X-cable for 2 years). Maybe that's the cause of it? Because that's a part that also produces quite some heat.
anyway I've always been reflowing around the cores itself and around the System Bus etc, but as you can see in the picture below the heat marks are completely somewhere else.
Can someone tell me what parts those are? Used for what? PSU? Wifi?
