In reply to Julian Prieto:
anywhere facing W / NW would be a good choice although N aspects don't seem too bad in the cairngorms.
Obvious crags:
Aonach Mor West Face
West Face Aonach Dubh (could be in it may have been cold enough)
The northern corries (mostly Face NNW, avoid fiacall ridge area in Coire an t'Sneachda, Mess of pottage should be more scoured again than the main corries).
Lurchers Crag (I'm not sure on safe approaches to this crag so you may want to look in to this further)
erm I'm sure there are more options too, you can do an advanced search on here
