i have recently changed pc case as the old one was too small for my 6870 GPU, the only problem i have is that the rear fan in the new case is a molex conection, which is fine but everytime i boot my pc its saying no rear fan press f1 to continue and its getting annoying now, i could just leave the old fan in but then the bigger case is not getting the correct airflow i need to keep temps down as its only a small fan from the old case. Any help would be greatly appreciated, even if theres a way to turn the warning off would be helpful.

I think there's usually a setting in your BIOS to set it to not check for a fan. Just run through the BIOS until you find it and set it to "No Fan" or "Do not check" or something like that.
