I looked twice last night and could not find it and this morning, upon a third inspection of the site, I did find the measurements I was originally seeking out so I guess third times a charm?!
 
I feel quite stupid that I couldn't find measurements for a simple ATX motherboard yet I can configure and build a fully liquid cooled rig.
 
 
 

So your on stock bios ?
 
with +20deg CPU heat reporting for 1800x and wondering about 60-70deg which is actually 40-50.
 
What was you problem ?
 
Yes you should update to latest bios from gigabyte website for your motherboard.

Download HWiNFO64 and look at the Sensors. Scroll down and find two temperatures, CPU Tctl and CPU Tdie. I believe they'll be on two separate lines. Tctl should be 20c higher than Tdie. Ignore Tctl. Your concern should be the Tdie temperature. That will correspond to the "CPU Diode" temperature in Aida64, "Package Temperature" in HWMonitor, and the temperature Ryzen Master shows. Like the previous comment mentioned, Ryzen X series have a +20c offset, but let's double check.
 
I'm also concerned with the Hyper 212 Evo. The reason they offer an AM4 mounting bracket is because it's not compatible with AM4 boards out-of-the-box. At least that's my understanding. I don't have one, but I'm surprised you got it to work without it. Just because it's making contact doesn't mean it's applying proper pressure. Oh, and "fully cooked" grain of rice. Size matters. 
 
You may be able to adjust the fan curve in the bios for something more aggressive. I've never used Corsair Link, so have no idea what it does. The fans should be spinning much faster than 30% at those temps. For the record, I usually recommend not exceeding 80c while overclocking, but at stock settings, I can't see another reason for your temperatures to be that high. There's also the possibility the 212 Evo just isn't good enough for eight cores/sixteen threads, regardless of its 180w TDP rating, but I would crank those fans up to make sure, first.
