Hi all,

I have Poweredge 2970 running ESXi4 server.

It have DRAC5, PERC6, 2x Quad port NICs installed.

It's located in a ventilated environment, where temperature wont never go higher than 25 celsius degrees.

Problem is it's fan noise, it's too high now, after I attached two NICs.

I did some testing and find this:

Only DRAC5 attached. Fans: 4350 rpm.

DRAC5 + PERC6 attached. Fans: 5700 rpm.

DRAC5 + PERC6 + 1 NIC attached. Fans: 6300 rpm.

DRAC5 + PERC6 + 2 NIC attached. Fans: 8700 rpm.

When I run this tests, system board probe temperature was 21 celsius degrees.

Is there anything to turn fans down, (I'm sure, 4350 rpm will keep it cool and happy)?

Please let me know.

 

Regards

Petteri
