Omri open this thread for me actually,
the problem is the cooler that makes terrible noises so i un-plugged the fan and set it off, from then the problems appear, I would like recommendation how to cool the card without the fan the came with it, I mean different way - thanks.
i forget telling the fan part to omri, sorry
Purchase an aftermarket cooling kit. There are lots of overclockin sites/stores that will offer the correct cooling. It comes down to what you prefer really. You can go liquid cooling for the whole pc and use water blocks or you could stay with air and get an arctic cooling or other manufacturers cooling.
Personally I have arctic cooling and it is serving me really well. Tricky and fiddly to put together but sooooooooo worth it.
