How do you see this effect?
It looks like you've got the right Arts and base + R/T/D.
The discription of the effect is somewhat lost on me, however.
Well, the rules say that any fatigue lost means one hour more of unconsciousness before to recover the first recover, so many level are really lost. Many hours are unconscious.
@Lasse, the spell causes the loss of 5 fatigue levels in 5 rounds due to extreme cold. You cannot recover them for Sun duration.
I do not think the spell works well. Such extreme cold art such speed would cause death, not just loss of fatigue.
Ignem already has a peIg soell that causes the loss of ONE fatigue level at around level 20, IIRC, so losing FIVE at 5 levels less seems to be somewhat out of sync to me. Extreme cold that makes you tremeble A LOT (concentration rolls to do anything) and loss a fatigue level for each diameter would be OK, but this is too sharp to be possible IMS.

Thanks Xavi - that was a big help 
I do not like the interpretation of game mechanics in this spell.
To me it is the same as inventing a Pillum of Fire with Sun duration so that the taget is constantly engulfed in flames that cannot be quenched, causing +15 damage every round. To cause more damage with one spell, you should not increase duration, but increase Base effect IMO. What you are looking at here, is a spell of a much higher magnitude, if possible.
The level of the PeIg spell to make lose fatigue is 15, just because the range is voice; is because the other spell is Range voice. This can't be used during one fight, one thing more, spells or help can prevent more heavey problems. One duration spell have the disadvantage/advantage of can be dispelled.
Actually, you can use pilum of fire with duration to burn a person round after round (as long as they stay in one place.
Same for the fatigue spell. It can cost a fatigue a round until person passes out and then add extra hours but only as long as the target stays exactly where they got hit by the cold.
Remember, you are not casting something that is attached to the person. You are creating a fire or cold spot in some location. It doesn't move once created even if it lasts 5 rounds or 100 rounds. Even if the spell is touch, you touch the person and create where they are standing. they then can take a long step and be out of the area of cold and no longer taking damage or fatigue.
It is one of the limitations to using ignem. You could create it duration and then create a ReIg spell wtih a duration to move it around to burn a person for multiple rounds or cause fatigue multiple rounds.
So... he can be moved by one ally and the effect of the spell ceases. Well, by me it's fine. And it'ld be covered by "the help" that i say.

Just a quick note.
The guideline says "freezing" the target (at Momentary Duration) causes the loss of 1 Fatigue Level.
I'm not sure one can extrapolate that sustaining the PeIg effect for a longer Duration will inflict 1 Fatigue Level/round, rather than simply preventing the Target from recovering that single Fatigue Level.
Considering that not everyone is convinced that being the target of multiple castings of Winter's Icy Touch will cost you multiple fatigue levels*, the extrapolation is non-trivial.
