add a lil DeoxIT and trouble free, wet locations i use Corriosion X and their HD (literly can submerge almost any electrical product under water and yes it will work) Caution: WARNING!!! use and do at your own risk.
And yeah, Yeah Racing Fans are good, i use others but this size for esc's works well for mine.
