Alpenföhn Brocken 4 Review

Alpenfohn Brocken 4 dual-tower air cooler, 6 heatpipes, dual 120mm and 140mm fans, 160mm height, 250W TDP, AM4/AM5/LGA1700 support, quiet German-engineered design.

Brocken 4 continues Alpenfohn's long-running dual-tower line with mismatched fan sizes, a 140mm intake and 120mm exhaust, tuned to keep noise low while still moving enough air through six heatpipes to handle a genuinely warm CPU. It's a niche European brand in most markets, but the engineering focus on acoustics over branding shows in its noise ratings against similarly sized dual-tower coolers.

Comparison to Alternatives

Against the be quiet! Dark Rock 5 in this catalog, both prioritize acoustics over aggressive marketing, with Brocken 4 undercutting it on price while landing close on noise-at-load figures. Compared to the DeepCool Assassin IV, Brocken 4 gives up some outright thermal ceiling for a quieter operating profile at equivalent fan speeds.
