The Ravenloft Monster books, Denizens of Darkness/Dread have corrupt elementals such as the pyre, grave, blood, and mist.
I know the Penumbra Fantasy Bestiary has ice elementals (I wrote them), as well as tiny elementals and I think mischievous small fire ones called sparklings
IIRC.
EN Critters has a tundra terrain themed monster book that should have some cold elemental themed monsters in it. It is currently on sale for $1 until the end of the week.
