Have you updated the Bios???  I've heard you must flash your bios with the older chip so the 3000 series chips will work.

NVM, Misread you updated the Bios already, buddy had a B450-F motherboard. 

Chips run hot, and I think it has to do with not having AVX.  I don't really wanna push it since it shouldn't matter if it's 3.8 or 4 ghz.
I had a corsair H75 and MasterAir MA610P but the system just runs to hot for my liking.  
 

I'm thinking about doing a new rig sometime this month.  Asus AM4 TUF Gaming X570-Plus /w a 3900X Ryzen…  Maybe a 5700XT Graphics,  DDR4 memory   

You can stream pretty good with 6 cores using OBS: Open Broadcaster Software.  Most games use 4 cores still.

Stay with the i7 9700F.  You wouldn't really see an improvement. 

Call of Duty warzone wouldn't let me play on my Xeon w3670 /w a 970 GTX video card.  It's hard to believe that Intel Core i3-4340, 2 core / 4 thread (Intel's fourth gen cores) is somehow able to run warzone.  The i3-4340 is the minimum requirement for CoD Warzone. 

Basically warzones requires Intel fourth generation chip or higher.

i7-9xx series and the Xeon 35xx, 36xx, 55xx, and 56xx / LGA 1366 sockets slowly becoming obsolete in the high end gaming world.  My x58 gigabyte board is going to be retired.

I'm thinking about going with a Asus AM4 TUF Gaming X570-Plus /w a 3900X Ryzen...
