Bad Fan on 622 receiver

[ronjohn]

Has anyone had the fan go bad on a 622?

Mine is still working, but every so often the fan bearings sound like a bicycle with playing cards in the spokes. The sound goes away after about a minute, but it makes me think that the receiver might fail sometime soon. The maximum temperature is 138, which I don't think is terrible.

The sound you hear is when the fan is actually running. 622 fan only runs if the unit overheats or at reboot, 99.9% of the time it is not running.

No, I hear the fan running quite frequently and can feel the airflow.

The extra sound that I hear is definately not a normal fan sound. I will try to record it at some point.

722 fan runs all the time but not at full power like it does after a reboot. 622 might be the same.

Better read that long thread about hot 622 - no need to guess for some question answered there.

Well here is an mp3 of the sound. I could not get a good recording, there is a lot of background noise.

The recording makes it sound like a pop, but it is actually more like an electric pencil sharpener for a second or two.

Not that loud as I expected from your posts.

I recorded it with my laptop. The recording quality is very bad. The sound is actually about the same as my daughters battery powered pencil sharpener. It is happening more often now, about half the time.

You can find in that "622 hot" thread what's settings FW doing to LM75 and comparing to you 138° F, I can say your DVR hitting the threshold.

Thanks, I put a small 120V fan pointed at the receiver and haven't heard the fan try to start and rattle since. If the average temp drops, I will probably try the usb fan in the thread you mentioned.
