We just got a couple of HP DL360 G7′s, and I notice it has vents on the top. More hot air seems to exit through these vents than it does anywhere on the back. All our servers in the past have always vented all the hot air through the back.
How are these servers with top vents supposed to be mounted? Everyone always says airflow is best by not leaving gaps on the rack, but it seems like a server right on top of it would receive a lot of heat.
I really wouldn’t worry too much about this. The HP ProLiant DL360 G7 has a small series of perforations along the rear 7-8 inches of the chassis lid (see the center-left of the photo below). This is just to provide ventilation for the full-height and half-height PCIe slots in the system.
It’s quite okay to stack these systems in a rack. Cold air is drawn-in from the front and exhausted out the rear of the chassis. ProLiant server have a high thermal tolerance, so unless your systems are full of RAM+disks+PCIe cards and your ambient temperature is consistently over 85 degrees Fahrenheit (30 degrees Celsius), you’re fine with the default setup.
NOTE – if any of the aforementioned do apply, there is a BIOS switch to enable “Increased Cooling” that will force a higher system fan speed.
