Thread: HD DVR Internal Temperature

Just got an HR23-700 and I noticed it's running at 127*F, although I'm currently downloading OD content and watching a recording of Flash Forward. Is this normal? The old DVR ran about 115*F on average.

They vary, my HR20's all run between 116* and 127*, so yes, this is normal.
If it goes any higher, I would be concerned though.

Raise the unit an inch and see if the temp goes down.

Is it in a cabinet or on top of something else warm?

My hr20-100's run at 100 degrees. I did put a little sticky felt pad under each rubber foot to raise it up a bit as jdspencer recommended.

I believe the -100's ran a little cooler.
Mine is in the entertainment center, but has a big Yamaha recvr on the shelf below it, but it also has plenty of access for air.

Mines currently running at 120* and has been on since around 5 tonight.

Yeah, it's in a cabinet on top of the Onkyo for now. When I upgrade the TV I'm gonna get a new stand with an open front. For now it's trapped behind a glass door. I thought it was a little warm, but I'm just curious if 127 can damage it.

I used to run a little 12v computer fan on mine when it was in a closed cabinet. Made a huge difference.

Sounds like other folks are running them that hot, but who knows what difference it makes to the mortality rate.

Closed cabinet is generally not a great idea. On top of a receiver is also not a great idea.

How fast is the receivers internal fan running? Can you hear it from a couple of feet away? If its audible at that distance, the receiver is running the fan pretty fast trying to keep itself cool. Mine are barely audible at more than a few inches away.
