prpr said:Why don't you just look at the Smart data (on the Diag. page) and see what it says the max. temp. of the disk has been and what it is now?
What tipped me off to the overheating issue is that at its worst last summer, I put my hand on the case above the HDD and it was so hot I couldn't keep my hand there.
As for the fan itself... I've had the sysmon package installed for some time and while monitoring during a HD recording and playback the temperature rose into a 'fan on' region (dark blue) and did no observe any spin up of the fan.
The hard drive is no longer in the HDR as I've replaced it, but out of interest I plugged the HDD into my PC and used SpeedFan to look at the SMART info. The peak temperature was not that high at 64 degrees... however, there was an "airflow temperature" warning in addition to a dire warning of imminent HDD failure. I don't think these values are directly in Celsius, but the current value was 72, the warning value 45 and the worst value 38.
