I want to order an OTA DVR for my daughter and the Quad looked good but as an engineer I am concerned about all the HEAT on the HDD or SSD drive. That can’t be good and it poses a potential fire risk. Does anyone know if all of the Tablo tuners/dvr’s run that hot. We were looking for a 4-tuner model rather that the less expensive 2-tuner model. It appears that they may not be making the 4-tuner Tablo OTA DVR anymore as only refurbished ones are available. I wonder if those ran hot also?
