Either works but I personally really enjoy /Fiery paired with Ice Control. The extra damage and the endurance cushion in Consume really helps out. However, Power Boost is very nice power in its own right. If Chilling Embrace worked on Dominators the way it does on other archetypes I think I'd have a harder time picking.
Ice Control itself is usually regarded as somewhat weaker than the other Control sets, although the weakest Control sets are still pretty effective. I like the set because it is different and, compared to a few other sets, relies less on fighting statues.
O_T,
Hey, I like figjting statues, thanks. Tho there are enough things that resist control that its really not always like that. But Ice and Illusion might as well be fighting statues. The fact that the bad guys wiggle around is just an illusion. 
M,
Icy Assault is fine. If it fits your concept, go for it.
If you wanted to have an alternative that you colored blue, consider Psychic Assault. Pretend that the modified blue effects are "cold energy" or something. And Drain Psyche can be Leech Heat.
Anyway, just an option. Ice/Ice should be fine.

I have an idea for an ice themed character - I love the ice primary - but do you think I'd be better off with the Ice or Fire secondary?
I'll be doing a 50/50 mix of team and solo. I just want a secondary that is effective and contributes. I like Ice but the forums seem to unanimously favor Fire for AoE and single target DPS. I figure I can just color the fire attacks blue to fit the theme.
Any thoughts? Also, if Ice is a really bad primary and hated on teams please let me know
Thanks
