Advertisements Hi - I have been dealing with a noisy fan in my Roamio OTA, for a couple of years. I do see a slotted area that repeats in the fan casing. I do not want to remove or replace the fan. Did you drop the oil in one of those slots that surround the fan? Or one specific slot or other place? I'm not clear if it could be any of them, or I'm looking at the wrong place. Can anyone help by clarifying or sending a pic? Did this fix continue to keep your fan quiet? I have already dried canned air many times, and cotton swabs for cleaning, but the noise continues. Thank you so much!
