split the risk
get a spare few old paper packages, and label what you put in them with masking tape. Make a deal with food services, to put the largest part of your stash in the commercial refridgerators, and then only go and ask to get it out every two weeks of so.
Work from the smaller unchilled stock kept in your dorm. If it is B&W don't worry.
If it is in the north part of the northern hemisphere, find a room with a north facing window, and put the paper on the window ledge. That is almost almays the clodest part of any dorm I ever lived in or saw, and usually even colder than the measly little bar fridges fund in most dorm rooms.
