When I checked mine last night the high temp was 122F and low was 106F the average was 112F mine is on a open sides front and back glass shelving unit its the only thing on the shelf located aprox 3 foot off the floor. My hard drive has not died yet but I have been getting more and more hard drive dignostics operations error 599 almost any time I do a search or change or create more than one timer or dish pass. I have been thinking on investing it a usb powered note book cooler to see it that will help the cooler the hard drive the better I would think. And without putting the unit in the frigerator or opening the unit to add additonal fans or cooling devices that is about the only option.
