TA140 The TA140 is the most powerful 140mm cooler. We use the premium fin on the top and the extra premium heat pipe. The wide spacing of the aluminum fins and the large cooling surface guarantee a far-above-average performance, even at the lowest fan speed and noise. The special air symmetrical design of the cooling lamellas serves to minimize the air resistance and contributes measurably to efficient heat dissipation.
