[Standard R33 Intercooler]

i have a skyline r33 series 1 and i have the standard side mount intercooler i was wondering if i attach a thermo fan to the front of it will it give me colder air and keep the turbo cooler and will i increase the horspower ? or will it restrist the air flow through the cooler when driving at faster speeds when more air could pass through ? can any one help me thanks .
