This study aim to determine the influence of the combination of sprinkler and fan on the microclimate condition of the pen, physiological condition of cattle and feed consumption of Friesian Holland (FH) dairy cattle. A total of eight dairy lactating cows were used, four (4) in their first lactation and the other four in their third lactation. Experimental animals had an average body weight of 409.13±19.02 kg and were divided into two groups. The experimental method was a simple balanced crossover design with two treatments; the sprinkler fan (P) and non sprinkler and fans (TP) as a control. Implementation of the research was conducted in two phases. Before the first treatment period, an early stage research was conducted to observe the critical points of the appropriate time to carry out sprinkling. The pre-study obtained critical points at 10.00, 12.00, 13.00, 14.00 and 16.00. At the beginning of the treatment, experimental animals underwent an adaptation period in the first week. The parameters observed were microclimate of pen, the physiological conditions of the cows and dry matter feed intake. Data were analyzed using analysis of variance. The results showed the pen temperature conditions were significantly different (P≤0.01between the treated group P and TP i.e. 27.91±1.58 and 29.41±2.34oC respectively, humidity of enclosure were significantly different (P≤0.05) i.e. 73.64±8.73 and 71.40±10.35% respectively and Temperature-Humidity Index were significantly different (P≤0.01) 76.42±1.23 and 78.03±1.99. While the physiological condition and rectal temperature were significantly different (P≤0.05) between the treated group P and TP at 38.58±0.35 and 38.82±0.41oC respectively, pulse rate was significantly different (P≤0.05) at 64.12±5.96 and 68.44±5.85 beats/minute, respiration rate were also significantly different (P≤0.01) at 23.56±3.36 and 33.56±8.02 grunts/minute. Treatment with sprinkler fan for 10 minutes can reduce the temperature inside the pen,
