Supplemental Cooling for my Gen8 MicroServer and P222

By: John Stutsman


In preparation for the Home Server Show Meetup on September 20, 2014 (see “Meetup 2014 Registration and Info”) I wanted to show participants modifications I had made to my HP ProLiant Gen8 MicroServer as well as, “hopefully”, an interesting demonstration of how it all works together. This blog posting is intended to summarize the basics of what I’ve done with my Machine as demonstrated at the #BestMeetUpEver.


Cooling the CPU Heat Sink


4 Evercool EC3007M12CA installed on CPU Heat Sink

After installing my Xeon E3-1265Lv2 and lapping my warped heat sink I ran some of my own and reviewed other’s Temperature Tests and decided, at least for myself, that I was more comfortable running with the BIOS fan settings on Increased Cooling, but there were times when I wanted to be able to test things at the Optimal Cooling BIOS fan setting. To increase my comfort level I looked at different ways to add additional cooling to the CPU.

I tried to mount 2 Noctua 40x40x10mm but found I lacked adequate clearance to reload the system board in the MicroServer so I ended up just mounting 1 Evercool 30x30x7mm EC3007M12CA on the CPU Heat Sink .

Later, with additional Evercool’s, I mounted 4 Evercool 30x30x7mm EC3007M12CA fans on the CPU Heat Sink on my HP ProLiant Gen8 MicroServer. For power to the 4 Evercool fans I modified a Molex to 3 pin Fan power adapter with 3 additional 3 pin Fan connectors soldered on.

Cooling the Broadcom Chip at Location 13-LOM


Enzotech BMR-C1 installed on Broadcom Chip

HSS Forum member “FireBaall” outlined a process to apply the BMR-C1 to the Broadcom Chip on his Gen8 MicroServer in the HSS Thread “G8 Sensor Location?”.

Following the “FireBaall process” I used an Enzotech BMR-C1 to cool the Broadcom Chip at Location 13-LOM on my Gen8 MicroServer.

Cooling the P222


Supplemental fans cooling P222

HSS Forum member Tangcla started a Thread P222 Temperature in Gen8?”.


During the back and forth in this thread Schoondoggy noted in message #18 that on page 32 of the “HP Smart Array Controllers For HP ProLiant Servers User Guide” (HP Part Number: 469988-009, August 2012, Edition: 9) that the operating range of the Smart Array Controllers is 10C to 55C.


With that information, many of us in the Forums started looking for ways to bring down the temperatures on our P222’s. I was encouraged by the performance I saw with a 2nd BFB0512LD directed towards the P222 Heat Sink that brought the 10-PCI1 down close to 50C range.

Resulting in:

Fans Used:

2 Schoondoggy Blower Fans – one directed to the back of the SDM and the other directed towards the P222 Heat Sink: Delta Electronics BFB0512LD

30mm Fan: EverCOOL FAN-EC3007M12CA

40mm Fan: Noctua NF-A4x10
