I have just upgraded the HD in my Sky+ PVR2 with a Samsung Spin Point 7200rpm unit. The install went like a dream and only took about 20 minutes, the new HD is working flawlessly and is whisper quiet. The only fly in the ointment is the fan which is now on all the time. It's not as if the box isn't getting plenty of air flow around it as it sits in a well ventilated position. In fact now the fan is running constantly the Sky box is quite literally cold to the touch. Is there no way of regulating this fan so that it isn't running all the time?
