My mobo is the MSI z97 gaming 5 and case is NZXT H440 dont want to use the fan hub on back of case and was looking at plugging the fans direct into the mobo but fans are 3 pin and the fan connectors on mobo are 4 pin if i connect the fans to the mobo will it still control the pwm or will they still just run at 100% with them being 3 pin like they do on the fan hub or will the mobo control the pwm just like it does with 4 pin fans. Thanks for reading.
