I have successfully used this method before, but it is a bit hit & miss. Someone else that I suggested this to on this forum also put bags of frozen peas around the drive to keep it cool while retrieving data and got a much greater time to enable him to do it. My method is to wrap drive in absorbant tissue and place in plastic bag and seal it. Leave in freezer for an hour or so then connect up and try to get data off. Personally I prop mine up outside the case but connected as an internal drive. If you leave it in the wrapping. with the connections made through the mouth of the bag, you should be able to try the frozen peas as well, though I should imagine a frozen joint of beef will do just as wel. Usual warnings apply as regards 'don't try this at home unless you are as desperate as I was' and disconnect from mains while you are inside computer.
