According to this site: http://forum.digitalspy.co.uk/board/showthread.php?t=156344 under section 9, QUOTE: A lot of upgraders have noticed that the Fan in the upgraded Sky+ box stays on for a long time, if not all the time. It is the belief of many that this is due to the firmware. The fan on the Sky+ machines are quite robust and in most cases the fan noise isnt noticeable, even if you sleep in the same room as the Sky+ unit. END QUOTE: Not noticeable, is he kidding. It makes more noise than a fog horn & wakes me up if sleeping. Anyway, i have not yet had time to open the box however i am wondering what is the best drive to upgrade to is. With regards to drives that make less noise & generate less heat than the stock 40gig drive. I see peeps are using Maxtor but what about Seagate ? as these make less noise & i would assume generate less heat maybe. What about the fan, has anyone manage to change the fan for one that can do the same job if not better & make less noise ? At present i don't have the quad LNB or twin cable anyway so cannot properly use the record feature, so can i just take the hdd out & thus the fan will not come on ?
