With the warmer summer days starting to hit, my server is increasingly going into thermal protection shutdown due to temp sensor #21 reaching critical level (58*C), as reported in ILO.
The fans are all running fine but unfortunately, the server is not in a climate controlled room and there isn't much I can do about the ambient temperature. However, if I know where sensor #21 is, I can try to improve the airflow around that area. And if it's an IC, I can add/beef up the heatsink to improve cooling.
Does anybody know where that sensor is?

Does it matter which sensor #21 is? What would you actually do about it?
Can you check your ambient temperature? What can you control about your environment to keep that within a reasonable range? Are you absolutely sure you don't have a failed fan?
--edit--
It makes sense to ensure the firmware of ALL of your components is up-to-date. For you, that means your system BIOS, ILO, RAID controller, NIC, backplane and disks. These can all be covered by the HP Support Pack for ProLiant bootable DVD. Please download and run.
Check the internal health LED on the server. If you're running a supported version of Linux or Windows, install the HP management agents and check the output of
hplog -tto get temperature sensor information. The output of a standard DL180 G6 config looks like the following. Correlate your results with mine:note: there are four fans in this system
