That information helps, but we need a bit more.

1. What is the maker of your motherboard, and exactly the Model Number (or name) of it? Then we can look up its complete manual and specs to see what its fan headers can do.

2. Cooler Master makes many fans, and their website for that case does not make it clear which fans it includes. Do you have that case already, so you can examine it? We need to know these things about the fans. Look closely at all the fans. There are three in the front that all should be exactly the same. The one in the rear may be the same, but the manual says it is slightly different.
(a) Look at the connectors on the ends of each fan's wires. For the three at the front, they may all be connected to an adapter. The fan wires will each have a connector about 8mm wide with two ridges running down one side. How many wires are there at that connector - 3 or 4? IF these fans are all plugged into an adapter, its connector on the other end will look different. It will be about 2cm wide with space for four round pins inside a shroud, but actually only 2 pins are in it. That end may already be plugged into an output from the Power Supply Module. That is a way to connect all those front fans to a constant 12 VDC power source so they run at full speed all the time with no control. But we will try to find a way to remove that adapter and connect each of the front fans to a mobo fan header that can provode BOTH power and speed control for you. To do that we need to know whether the wires coming from each fan are 3 or 4.
(b) Now for the rear fan, same question: are there 3 wires from it to a connector that has 3 holes, or are there 4 wires and holes?
(c) Just from the appearance, is the rear fan exactly the same as the three at the front, or slightly different?
(d) IF you can see labels on the fans, tell us what name or model number they say.
