Dell "System Fan Failure"

[AydenTPC]

So one of my used PC reselling projects consisted of recasing a Dell Inspiron 660 into a Bitfenix Prodigy M Case. The process wasn't too hard as the Inspiron 660 motherboard has a surprisingly standard design. The mounting process was fine and even the front panel headers could be installed easily. However, whenever I turn on the PC, I get an error message saying "System Fan Failure" and it directs me to press F1 to continue (And it goes to Windows right after). I checked and all of my fans were spinning just fine, even the CPU cooler seemed to be lacking of any alarming dust. I suspect maybe because the chassis fans are not Dell fans, they are not compatible? The fan attached to the fan header is actually a 4-way PWM fan hub that I use for the two included Bitfenix fans. They spin normally but cause an error message and sometimes shut down the PC when running Unigine Heaven. Any way to at least disable this error message?

Replace the fan with the correct fan the motherboard was using.
