hi all.  im new and looking to dip into the bitcoin pool.  ive recently ordered parts to setup an entry level rig.  im not trying to get rich, just want to earn a few coins and see what happens. 

im setting up a ASICminer block eruptor blade.  ive got the electricity and internet part figured out.  i will be keeping the rig in a garage and while the ambient temperature stays around 60F, ive had thoughts of taking advantage of this winter and may pipe in some sub-freezing air.  i know computers like to stay cold, but how cold is "too cold"?  will keeping it this cold help with performance?  will it damage my blade? 

any insight will be helpful

thanks guys
