FPS issues, possible hardware issue?

Hello there, well for a while my computer has been having FPS problems just after my motherboard and CPU had both died. We replaced both of them with the same Motherboard(970A-D3P by GIGABYTE) and CPU(Intel(R) Core(TM)2 Quad). My fans used to run at a much faster speed then they do now, I even upgraded to a liquid cooling system yet the fan speed is basically the same. I even went into BIOS with the latest version of it and tried to max out the fan speeds, but nothing changed at all. My temperatures are great yet my FPS just drops, but I still think that my fans are running too slow. If it's not a problem with the fans, then is it a problem with some new hardware? I only have had FPS problems, specifically drops, after both of those had died.
