Aurora R4, chassis fans question
R4 motherboard has three fan headers per manual pic: cpu fan, sys fan1, sys fan 2.
top lighting board has sys fan, cpu fan, mem fan
afaik, the cpu fan header on lighting board is not used if the stock liquid cooler is used.
is this extraneous cpu header on lighting board reserved for air cpu cooler to replace the liquid cooler? It would help to know if one upgrades motherboard and decides to use air cooler.
there appear to be 5 fans: front pci fan (to MIO), hdd fan (to MIO), radiator fan (?to lighting board sys fan), mem fan (to lighting board), VRM fan (?to where).
someone said that MIO sends sense wire to motherboard cpu fan header.
what wires connect exactly to motherboard fan headers (cpu fan, sys fan1, sys fan 2)
it seems HWmonitor app can sense rpm on all these headers.
Wrong connection in this photo. Per Tesla
Asetek cooler's radiator fan should instead use SYS_FAN header.
"Top Lighting Board" Connections:
CPU_Pump (Asetek Cooler) pump
Sys_Fan (Asetek Cooler) radiator or main system fan
CPU_Fan - No connection

Thanks for the tips! I just acquired the R4 and it serves more as a piece of collection for the time being as I consider it to be one of the most beautiful tower ever and certainly more expressive than the following iterations.
I tried to optimize the airflow as I wasn't impressed by the original configuration. I inversed hdd fan, biggest chipset fan, memory fan so the most air is evacuated. I must precise that I use a blower-style GPU controlled by MSI Afterburner. Let's see if I'm satisfied with the noise & temps.
Your fan upgrade is great. I owned before a Scythe Shogun cpu cooler and it was as efficient and silent as water-cooling
The only reason why I am a bit reluctant to put a 12 cm fan above the small chipset fan blowing on the radiator, as you did, is because in my mind both airflows work against themselves, so it would be better to disconnect the small chipset fan.
