Installing a custom fan is a problem for any newbie although it’s simple as 1,2…3. But still a lot of people don’t know how to do it. They either get confused with the fan placement or with connecting the cable. Today I am going to show you how you can do this in just under 10 minutes. I will show you step by step process and you can install a new fan right now after reading this short guide.
Step 1: Pick up your fan and a screwdriver
Unbox your fan and it’s accessories such as screws from it’s box. Take a screw driver which can be used for those screws. It’s generally of the same size which is used to install other components in a computer case.
Step 2: Unscrew your case side panel and remove it
Remove all the power cables from your case and put it on a table to remove side panel. If you have thumb screws on your case side panel then it will be easy to remove the panle Or you can use a screw driver to do it. Note that you have to remove the left hand side panel in order to access the inside of your system.
Step 3: Try to put screws in your fan before mounting
After removing your side panel, it’s now time to install the fan. But before proceeding try to put the screws inside the screw holes of your fan to make the spirals inside it to ease the process. You may have to put a lot of force to put screws into the holes because these fans come with plain holes without any spirals and you have to make them manually. Do this before mounting the fan.
Step 4: Mount the Fan
After trying to screw the fans outside the case, now it’s time to mount the fan in the correct location. Suppose you have to mount the fan for exhaust, mount the fan with the front side inside or you can simply figure out the side from where the air will be blown from seeing the blades. Some fans come with arrow marks on one side indicating the sides of intake and exhaust. But here the case is different. I am using a Corsair AF 120mm fan which doesn’t have any arrow marks. But you can see how I mounted the fan for exhaust at the rear.
If you mount the fan for intake just flip the fan to the other side.
Step 5: Screwing
Use the screw driver and then put screws in one of the top holes. Then put the second screw in the diagonal hole. This is important to make proper alignment and the screws will hold your fan tightly.
Step 6: Connect the cable
Now it’s time for wiring. Your fan will come with either a 3/4 pin power connector or a 2 pin molex connector. Modern pc case fans come with a single 3/4 pin power connector. You can either power a fan with 4 pin molex connector from your power supply in case you want to use the 2 pin molex connector from your fan Or if you don’t have the molex 2 pin connector on your fan, you have to use the 3/4 pin power connector that will be connected on the motherboard.
Locate a 4 pin or 3 pin power port on your motherboard which is generally present on the middle left/right, top or bottom of the motherboard. Each motherboard has it’s own 3/4 pin power ports locations differently on the PCB. If your power port is far away on your motherboard, then untie the fan cable and connect it on the port. The connector will go in one direction only and you don’t have to worry about putting it wrong.
Step 7: Finally check if it works
Now connect all the power cables to your case but do not put your side panel before making sure that your fan works.
Switch ON the Power button and see if the fan spins. If it spins, then congratulations, you did it right way and if not. Then recheck your wiring. There can be only a single reason if your fan doesn’t works if it’s completely new, which is faulty motherboard power port.
If the 3/4 pin power port on motherboard is not powering up the fan, then try to use the other ports present on the motherboard. If it still doesn’t works, then there is a possibility that your fan is faulty from the beginning. You can return it to the vendor.
I hope now you can install your fan inside the case easily and in case you have any doubt in installing your case fan, you can ask me in the comments section below. Cheers!
