How to remove the Intel CPU cooler from the motherboard? First, ensure that your motherboard is unplugged
from the power supply unit. Then, locate the CPU fan connector on the
motherboard. Grab the connector on both ends with your thumb and index finger. Wiggle the
connector until it disconnects. Next, locate the 4 plastic knobs that have
arrow symbols on them. Turn each of the knobs in the direction of the arrow. Then gently pull them towards you. You should hear a click sound. Once all 4 knobs have been disconnected from
the board, give the cooler a wiggle and remove it from the motherboard.
