Hi,
I recently get a R610 with two E5540, 32GB and iDrac 6 enterprise to replace my old server.
I upgraded all components firmware so iDrac 6 is v1.95 and all work fine and silently until I add an expansion card (SAS controller).
Without PCIe card FANs all run at about 4200 RPM with ambient temp around 20°C but after I added the card, FANs 1A to 6A only jump to 6200 RPM even with ambient temp as low as 15°C !
So I have three questions :
- Why both group of FAN don't run at the same speed ? the low rpm fan prevent air flow implied by the faster fan, in my mind it's a nonsense.
- Why FAN are'nt slowed when ambient temp falls ?
- Why FAN speed is not manageable thru iDrac ?
