Ho Ho Ho Happy Holidays everyone. Recently I just got a new IKEA desk. Somehow this desk has a very different resonate from my old beat up solid oak desk. I put my iMac on it, now it makes a very low pitch (around 60Hz) humming noise, it is not very noticeable in daytime. But at night when it's very quiet, it gives me a headache!!! One of those thing once you noticed, it will just bug you. Does anyone know if there is something like a pad that I can put under the iMac to absorb this vibration?
