Will it still work?
I don't think so. But you may be able to purchase an adapter.
That 4-pin connector is a so-called PWM connector. It's basically a normal fan connector which has one extra pin, so that it can change speeds depending on how hot the CPU or whatever it's cooling gets. It'll work just fine plugged onto a normal 3-pin fan connector, the fan will just run at max speed all the time. (PS. I'm using an old 92mm PWM fan as a casefan on an older PC connected to a 3-pin connector, and that's been working perfectly for a few months now)
