For me they don't vaporize the wax or remove it, they warm the ear drum and softens the build up of wax in it. If you place them right (it is best if someone else does it for you) the suction that is caused through the vacuum of the candle and the ear drum, can move the wax or dislodge a stubborn hard bit of wax. Us men get ear problems the worst, as when you hit 30, you end up with a forest growing out of your ears, which can slow down the natural process the ear does to remove the wax. One small hair, pointing backwards can cause all sorts of problems, Ear ringing, whistling, dizziness, nausea, off balance and even speech problems. Which is why sticking anything in your ears is bad, Cotton buds are the worst, like what KeiKei said and that they do leave small strands of cotton in the ear, which adds to wax build up. Skynet! Can I ask, is your cpu cooler a stock one or do you have one of them turbo high power coolers? I bought a corsair hydro dual radiator one with two 120 fans on it, and I have to say its the best thing I ever bought for cooling the cpu, is silent and my cpu has never gone above 31°C. Plus it is multi connectable with all the cpu's so it will last future upgrades.
