One of my receivers is an HR20-100 hooked with WHDVR and internet. Over the last 3 days or so the fan has been constantly running on it and when I checked the setttings for the internal temperature it was 113 degrees. I did have a Playstation 3 sitting on top of it but no vents were blocked. I removed the Playstation 3 this morning and the temperature did drop some but the fan was still running. Is this HDDVR about to die? Will Directv send a replacement for it running hot without any other issues? I have been wanting it replaced for a long time now since it is so old but each time I call with a problem they seem to patch it up and keep it working. Any suggestions or thoughts?
