Say, card been working fine until recently. If I blow if cool with a strong fan it works fine.
Any ideas what has happened to it?
It has an I2C connector that I've never bothered to connect - what does this control?
There is a large cable with several Sata cables - these go to the hard drives. With it is a soft and long thin core cable - what is this used for and where do I connect it? Is this the I2C?
