I have one of the below-mentioned kits and it works well. Aside from having small-diameter probes, the adapter to the standard vacuum hose has an adjustable air bleed, which permits decreasing the suction if using this device on your powerful shop-vac is too "fierce."
If you have a thermally controlled fan, dust accumulated on the heat sink for the CPU will inhibit heat transfer and cause the fan to run faster, thus producing more noise, even if the bearings are good. When I have sucked up as much of the dust as I can, my final cleaning step is to attach the hose to the exhaust of the cannister vac and use the air to blow the remaining dust out. You especially need to reverse flush the fins on the heat sink. You don't want to start with blowing if there is a lot of dust. Gets all over the place. If you have a special source of dust/hair, e.g., cats in the house, it can accumulate in the box very quickly. I don't really know what an iMac is, but if it is a tower unit that is kept on the floor, units kept on the floor seem to accumulate dust much more rapidly than desktop units.
