I have used Safale 05 at room temp for other brews.
Honestly though this is the best way I hae found to lower my fermenting temps without a ferm chamber:
This is simply a shelf, placed against the concrete wall in my basement. I have encased the shelf with sheets of pink foam insulation. You can see the insulation in the pic. I can only control the temp a small amount, but more importantly, temp is consistant and light free.
I think keeping it from light and consistant temps as low as possible is the best bet.
