The heat sink dissipates the heat generated during the operation of the chip. When operating electronic devices, situations often arise in which standard cooling is not enough. It is especially important to provide good heat dissipation for "overclocked" chips operating at frequencies higher than nominal.
Necessary
- - screwdriver
- - hair dryer
- - plastic ruler
Instructions
Step 1
Examine the heatsink and its attachment to the board. The most common fastening is with plastic caps or latches. You can also find fastening with a clamping bracket. This is the best option for fixing the radiator, it provides strong uniform pressure and ease of dismantling. In cheap devices, the cooling system is glued to the chip with special hot melt glue. It is most difficult to dismantle such a structure, besides, hot melt has mediocre thermal conductivity.
Step 2
To dismantle the heatsink installed on the chip using latches, you will need access to the back of the board. You need to remove the board from the computer case. Then gently squeeze the tendrils of the piston and press down on the tip. The piston should come out of the hole in the board. The same operation must be repeated with the rest of the latches. After removing all the caps, the radiator will easily detach from the chip. If this does not happen, try to carefully rotate the radiator around the axis. The thickened thermal paste can hold the cooling system fairly firmly.
Step 3
Use a screwdriver or other handy tool to dismantle a radiator that is secured with a clamping bracket. The task is to bend the bracket and disengage it from the mounting device on the board. Removing the staple can be physically demanding. In doing so, do not damage the board with the jumped off screwdriver.
Step 4
Dismantling radiators installed on hot melt adhesive is a rather risky operation. There is a great chance of damaging the chip. Therefore, dismantling should be resorted to only if it is impossible to do without it. To soften the hot melt glue, you need to heat it up. It is best to do this with an ordinary household hairdryer at medium power. Please note that overheating can permanently damage the chip.
Step 5
After heating, pick up the radiator with a sharpened plastic ruler. Be very careful to gradually swing the cooling system. If you press too hard, you can chip off a piece of the chip, and then it will no longer need any radiator.
