Hi,
Power - You can use HP Power Advisor at "https://paonline56.itcs.hpe.com/?Page=Index" , to calculate power usuages and based on that you can decide whether you need power supply upgrade.
Fan/cooling - Ensure that you have required fans installed for proper functioning of the server, One processor models include four fans and for second processor you should install two additional fans,
