Noise from Xfinity cable box

I just installed an Xfinity X1 cable box in my rack with my audio and video gear and it is the noisiest piece I have ever had in my system. I think it is a fan, but it runs constantly, even with the power switched off (standby mode?). I had been using a simple little digital converter from Comcast in the system that worked fine for HD video and audio, and was dead quite.  I am thinking of going back to it and ditching the DVR and voice capabilities.  Anybody else have this problem with new X1 cable boxes?

I went through the X1 fan noise issue about a year ago. There are two manufacturers/ models of the X1. You want the quiet one:

Every XG1-P I tried had a noisy fan.  I kept calling Comcast checking for a XG1-A and had them hold it for me so I could pick it up.

I had to put isolation feet under my Xfinity cable box to quiet the fan noise down. Doesn't eliminate it but does quiet it down quite a bit. Hope this tip helps you.

Thanks slbenz, I went back to Xfinity, complained and got a different (earlier?) version of the X1 box which is much quieter.  Now I can only hear the fan when I am within a few feet of the gear.
