hi FanMan, et al. glad to find this thread. i have a OTA that is 2 years old. it's never been very quiet, and more recently, its gotten very noisy so that i can hear it in the kitchen even though the Roamio is in the family room next door. i followed the online video of using Deoxit, and it actually helped, but 3 weeks later, the noise is back to where it was previously. FanMan: what are the advantages of the silicon mounts? is it meant to damp vibrations? or is just a way to avoid using the original screws/bolts. i'm not opposed to spending a few extra bucks, but want i want is a quiet fan that lasts. is the kit going to give me and advantage on these two issues over the standard evercool fan? thanks!
