Im upgrading my pc and i have crossed a problem the grahics card it has a fan. But the pc i have already has a fan pre installed. So do i NEED the pre installed fan or is my pc good with just my grahics card fan. Thx
I can just imagine some idiot removing the fan from their graphics card because they already have a fan on their PC and I just cringe...
I guess you mean your case already has a fan. It is completely independent of the CPU and graphic card fans. The case fan can be removed, but if you remove the graphic card fan it will probably burn in 3-4 seconds.
It won't. All GPUs throttle down when reaching a certain temperature now, and if it increases even more, it shuts down. The R9 290, for example shuts down at 105 C or so. (and begins throttling at 94 C)
Some cards won't even turn on the fans until they reach a certain temperature. I had a GTX 970 that had the fans off in 2D mode. Removing the CPU fan, on the other hand, will most likely lead to an emergency shutdown immediately after turning on the power.
