Oh yes you will. Air will transmit heat just as easily as water in a closed environment such as a water passage.
I have a 16" Kenlowe fan fitted in front of the rad. The standard fan has been junked, along with it's shroud. The fan is switched via a thermo couple screwed into the head outlet elbow. This TC opens at 100deg.C and closes at 95deg. C. In normal driving, even on hot days, the fan does not come on. The gauge stays just below half way. Only on steep climbs "off-road" or ditto deep mud will the fan operate. I have fitted a manual switch for emergencies i.e. the TC fails or if I want to drop the temp. before wading. This latter is really unnecessary, as wading will inevitably partially submerge the rad. and that will cool the system far more than a fan!
