How to install fan in dell 2400 desktop computer
Rear computer case fan?
This is going to be a fairly long solution. Advising you in advance.
1) Computer off, and unplugged from power.
2) Open the computer case, TOUCH the metal frame BEFORE you reach inside. Your body carries Static electricity. Touching the metal case will relieve your body of Static.
3) Remove the Processor Air Shroud.
This is the plastic U shaped part that covers the Processor, and Heatsink. It's at the back of the computer next to the computer case, and the fan in the rear.
First, unplug the fan's power cable from the motherboard connector.
(J30 connector on motherboard.
In-between Ram slot 1, and the Processor)
Second, you may have to disconnect the power cable for the Processor, in order to remove the Air Shroud. Disconnect the Processor power cable from the motherboard.
(J10 connector. Square connector on the motherboard to the left of the Processor, and down. There is a power cable from the power supply that goes to it, with a square connector, and has four wires in the cable. Two Yellow, two Black wires)
You may have to disconnect the 20-pin ATX main power cable also, in order to have room to remove the Air Shroud.
(J21 connector on motherboard. Long connector with 20 socket holes in it. It's on the outside edge of the motherboard, to the right of the ram slots.
The power cable connector is a Male connector. The connector on the motherboard is a Female connector.
The Male connector has a lock tab on the side of it. The tab is hinged so that it pivots. The top of the tab is squeezed in to release the lock.
This action draws a hooked end of the tab, out of the Female connector on the motherboard. While keeping the tab squeezed, the Male connector is gently wiggled side to side, while pulling up, and out.
Do Not pull on the wires, pull on the Male connector only. Use a gentle force)
The Air Shroud is gently squeezed in on the sides, with your fingers, and thumb. (Side that is towards the Front of the computer)
Then the side of the Air Shroud that is towards the front of the computer, is lifted up.
The Air Shroud pivots towards the rear of the computer.
The Air Shroud pivots on two round pins. Pins are made into the plastic shroud itself.
Each side of the air shroud, is gently pried out on the bottom where the round pivot pin is, and this action draws the pin out of the rear fan's mounting flange.
Remove the Air Shroud, sit it aside.
Now you can look more closely as to how the fan's mounting flange is attached to the computer case.
At this point I cannot lead you directly, only guide you.
The fan's mounting flange, may have small flat protrusions coming out of it, that go through the rectangular ventilation holes, in the rear of the computer case.
The flat protrusions has a hooked end on them, that hooks on the edge of the ventilation hole. Usual style, requires that you push the hooked end, towards the inside.
(Reference is made in relation to the outside edge of the computer case. The hooked end is pushed towards the middle of the computer case)
It may be a style of mounting flange, where the flange's edge has a lock tang that sticks up.
This lock tang is part of the plastic mounting flange itself.
The lock tang is depressed towards the computer case, and the fan is slid up, and out of a metal bracket.
(May be more than one locking tang)
Observing the mounting flange for the fan, you should be able to see how the fan itself, is attached to the mounting flange.
Usually it's another form of locking tang that is used.
The locking tang, or tangs, are depressed, and the fan slides out of the mounting flange.
If you did not buy a replacement fan directly from Dell, (Don't even know if you can), observe the fan's power cable connector.
Observe where the wires go in the connector. Look at the color code of the insulation of the wires. Match this wire color code, to the original Dell computer case fan.
Are the wires in the same place as the Dell fan?
If not, tell me. Post in a comment.
