I can attest to the 5805 and 5805Z cards running a little hot, the ones we're running tend to run in the high 60s and
low70s Celsius with fairly good airflow over them.
I've been running some 5805s for 3 years now, and 5805Zs for a year and they've been really good, stable, fast cards.
Imonitor everything on them (including temperature) with nagios and a simple script that uses the arcconf utility.
