Supermicro e300-8d low noise cooling upgrade & remove passive heatsink

[Sunnu]

My study room is a small space, the tiny 6U rack integrated with the bookshelf.
It requires some silent device. But while the server with high load, the fan noise is unacceptable.



So I bought three Noctua NF-A4x20 PWM. Replaced original 40x28 fan.



Test result:

ESXi 6.7 U1 with empty VM load:



With vCenter (10G RAM) and Cisco CSR1000v (4G RAM), 2 Hours load:



Result:
It's very silent when the fan with 4000rpm speed.
But I want to swap the passive heatsink to active fan heatsink.


After I removed the four screws, I found the E300-8d passive heatsink it's hard to remove from CPU.

I did not try to use more power, because it may be damage the CPU on the motherboard.

Is there anyone who has the idea how to remove it?

Hi Sunnu,

In order to remove it you need to have it a little hot. So after a you have put some load on the server, wait a little and you will be able to remove.
You cannot remove it if your CPU is cold.

I tried this setup but the noctua are not enough even with active cooling.

@Sunnu , attempting to create a home network setup that looks like yours. Can I use your picture to ask in chassis thread?

I got the e300-9d and it's also loud. I'm thinking about finding a bigger case to use bigger fans, to try and reduce the volume.

Please post back here anything you try and how it works out !
