A Intel E2180? Thats a lower end CPU and according to some reviews on NewEgg, it runs at 56c stock.
I have a Q6600 and runs at 31c-38c idle and 45c-50c under load with a Zalman CPNS 9700 cooler.
I would suggest getting a new aftermarket cooler because at the temperature I am sure it will burn out pretty fast and normaly the BIOS is not off by much. The same cooler I got is about 49-60 bucks but worth every penny.
I will admit its strange that it show that temp for the CPU but the mobo is running very cool.
