Last replyBest Answer
i just ordered a new case that has fan with a four pin connector , but my motherboard has three pin is it safe to pluge the four pin into the three pin?
Are you sure it's a 4 pin fan connector and not a 4 pin molex connector ? If yes , the notch will still line-up, your fan just won't be PWM controlled. If not, you'll need a 4 pin to 3 pin fan adapter, they sometimes come with the case.
