Quote from: skey on June 14, 2006, 11:36:54 PMNeither of the above heatsinks above seem to take advantage of thermal airflow. Sometimes smaller is better if it's less bulky. Is there any convenient way to figure out a useful minimal size you'd need?
Quote from: RDV on June 15, 2006, 07:14:06 AMThe one in the 1st picture does not take advantage of thermal airflow(though it's big enough to not need it), but the 2nd one is outside the cabinet. How much airflow do you need? It's in free air.

Quote from: teemuk on June 15, 2006, 11:39:37 AMI wouldn't trust only on heatsinking a high power amplifier in gig situations. The ambient temperature on stage is huge. It's safe to assume the power dissipation might start from heatsink temp of 40 degrees of celcius not nominal 25.
