Narrative:
Prior to departure; blower/extract system faulted on the ground. Maintenance reset the system prior to leaving. First officer walkaround found nothing unusual. Shortly after takeoff; the system faulted again. This fault resulted in the triggering of the avionics smoke ECAM as well. We opted to return rather than fly to ZZZ with the system compromised. The QRH and fom procedures were followed as the situation dictated including overweight landing procedures. As this was a repeat of the problem we had on the ground; we did not declare an emergency. We landed at 160000 pounds and a sink rate at touchdown of 100 FPM. Maintenance replaced a computer and filter in the system.

Title: AN A320 FLIGHT CREW EXPERIENCED AN EQUIPMENT COOLING FAN FAULT; FOLLOWED BY ECAM FOR AVIONICS SMOKE. THEY ELECTED TO RETURN TO THEIR DEPARTURE AIRPORT.
Narrative: PRIOR TO DEP; BLOWER/EXTRACT SYSTEM FAULTED ON THE GND. MAINT RESET THE SYSTEM PRIOR TO LEAVING. FO WALKAROUND FOUND NOTHING UNUSUAL. SHORTLY AFTER TKOF; THE SYSTEM FAULTED AGAIN. THIS FAULT RESULTED IN THE TRIGGERING OF THE AVIONICS SMOKE ECAM AS WELL. WE OPTED TO RETURN RATHER THAN FLY TO ZZZ WITH THE SYS COMPROMISED. THE QRH AND FOM PROCS WERE FOLLOWED AS THE SITUATION DICTATED INCLUDING OVERWT LNDG PROCS. AS THIS WAS A REPEAT OF THE PROB WE HAD ON THE GND; WE DID NOT DECLARE AN EMER. WE LANDED AT 160000 LBS AND A SINK RATE AT TOUCHDOWN OF 100 FPM. MAINT REPLACED A COMPUTER AND FILTER IN THE SYSTEM.
