4U Chassis Question

[dev_null]

Hello,
This is my first server build using enterprise level equipment. I am thinking of using this case:

I would like to if a cpu fan is necessary with the Xeon E5-2620 or if I could get away with a passive HS in a 4U case.

Thanks!

I'm sure you can but the question is why? If your concerned about noise level focus on those case fans. They make more noise then you can imagine and if you remove those guys a passive heatsink is out unless you replace them with something with a lot of cfm.

It depends on the heatsink. Check how many watts its rated to dissipate.

Pick the heat sink to match your CPU, that case comes with a shroud over the CPU area to direct airflow through the heat sinks without actually putting fans on them

Case is large enough to use any A/M HSF without reliance on case/chassis fans.

System noise will not be from CPU though. Chassis and PSU fans will drive you nuts first.

With the air shroud present in that case, you can use a passive 2U heatsink with no issues.
