Hello, I've a question about the fan configuration of supermicro barebones, which I don't understand.

For the example I take 2 "almost idententically" products:

5019S-L - E3, 45W and 2xFAN-0106L4 (34dba, 8.500rpm)
for an 80w CPU you should use FAN-0147L4 (57.5dba, 17.500rpm)

5018D-FN8T - Xeon D-1518, 35W and 3x FAN-0065L4 (52.5dba, 13.000rpm)


If I take the 5019S with a 45W-CPU, why do I need for the 5018D, which has a 10W lower CPU more/louder fans with more throughput/spin?

I mean, sure, I could change the fans, but I'd like to understand this barebone decission(s) from SM.

Some forethoughts:

- greater heatsink for the E3 -> better cooling effect
- backside-FANs need more throughput because the airflow way is (a bit) longer
