I have done some research on the average and maximum temperatures of CPUs, but I could not find information specifically for Intel Core i7-5820k.
Here are the relevant parts:

  • CPU: Intel Core i7-5820k
    CPU COOLER: CORSAIR Hydro Series H110
    THERMAL COMPOUND: Antec Formula 7 Nano Diamond Thermal Compound (applied as a thin line across the CPU)
According to the BIOS screen, my CPU remained at a stable temperature of 19 to 22 degrees Celsius for several minutes, until I turned off the computer. Is this a good idle temperature? Thank you.

Farwger - in that case don't bother much with what motherboard says. After You install Your OS, get CoreTemp RC7 and OCCT, run the Linpack benchmark, or Prime95/Aida64 and burn it up, and see what'll it do.

What is your ambient temperature? All computer temperatures are based on ambient.

Also, BIOS is not an accurate means of determining idle temperature. BIOS runs the processor at boot voltage, which is relatively high to assure that the processor will initialize under any circumstances. Further, BIOS does not utilize power saving features, so processor temperature in BIOS is higher than it is in Windows at idle.

Try Core Temp or Real Temp GT to see what your core temperatures are at idle. Make sure that your processor usage is less than 2% under the Performance tab in Windows Task Manager.

Farwger - holy molly, You live in a fridge? The BiOS readings are biased most likely, 5820k doesn't run with SpeedStep in BiOS, it runs on it's full clock and full voltage [not the TurboBoost clock/voltage though], so You should be hanging around 25-30°C at least. The other options is You have some badass case with lots and lots of fans and You come from Sweden, Norway or Finland and vent Your room a lot :)

P.S.: What motherboard do You have? And what BiOS version is it running?

Well, it is an average night (temperature wise), and I live in northwest Washington State. Unfortunately, I don’t have a thermometer on hand, so I can’t measure the ambient temperature.
My case is Corsair 650D. The only aftermarket chassis fans I’m using are two 140mm fans on the top (these are the fans that come with Corsair H110).
My motherboard is ASUS X99-A LGA 2011-v3, and it runs UEFI.
I should point out that this is my first PC build, and I have yet to install any software on it. I’ve only turned it on and monitored the BIOS for a few minutes to make sure that it was running smoothly. Tomorrow, I’m going to install Windows, download the latest drivers, and try to hook up an internet connection.

Thank you for the advice. Once I install Windows, download the latest drivers, and get an Internet connection, I will look into Core Temp.
Tomorrow, I’ll find or buy a thermometer to measure the ambient temperature. I like to keep my room cold, so ambient temperature won’t be a problem for me. Would you recommend pointing a household fan at my case?

A household fan might bed necessary in the summer if you don't have A/C. As for ambient, whatever your thermostat is set to should give you a rough idea. Most are in hallways, so if your room is a little warmer or cooler, you might be able to guesstimate what your computer's intake temperature might be.

Temperature is a major portion of my work here at Tom's. Keeping an eye on ambient temperature is vital when you're trying to compare apples to apples, so it's always important to be able to measure your intake temperature.

I agree. Too low is bad for ESD and too high is bad for condensation, long term corrosive effects such as on connectors and commponents, as well as the effects on cooling efficiency.
