My apologies for coming in so late.
I have 5 fans, two on front blowing out, and the two on the side and one in back blowing into the case.
I think that is (was) much of your problem. It is important to note it is the case's responsibility to provide a sufficient supply of cool air flow through the case. And generally, you want a front-to-back flow through the case.
What puzzles me is Antec factory installed case fans ARE installed for front-to-back at the factory (I've been using Antec cases almost exclusively for 20+ years). So how did your rear and front fans get reversed?
For side panel fans, I have found they sometimes help, but sometimes they disrupt the front-to-back flow. Typically I don't use side panel fans UNLESS they connect to a tube that directs the fan's flow directly onto the CPU or GPU.
Some chipsets come with small fans and they typically are lousy quality (noisy and seize up easily). I used to replace the chipset fans but replacements became harder to find (and were typically of same lousy quality) so I just removed the fan, cleaned the heatsink, ensured I had excellent front-to-back flow of cool air and surprisingly, no chipset overheating problems.
While true some CPUs are rated for temps higher than 60°C, I do not let my CPUs sit at or above that temp for more than a few seconds. While no harm to the CPU is expected, stability issues (like system reboots, freezes, and unexpected shutdowns) can occur. So when my CPU temps start touching 60°C, it is usually a sign I have a layer of heat-trapping dust blanketing the innards and it is time for some housecleaning.
Stock AMD and Intel HSF assemblies are excellent! Don't let anyone suggest otherwise. The only time you need to replace the stock fan is if it fails (rare - and they have 3 year warranties), with extreme overclocking (not recommended unless you really know what you are doing and have properly addressed cooling), or when setting up a HTPC (home theater PC) and you need "passive" (no fan) cooling for "silent running" (often done with "underclocking" for even cooler operation).
I note your first Speccy dump shows the motherboard's "System Temperature" is a nice, low 30°C. So I am not sure I am buying HW monitors 90°C readings.
I recommend a couple things. What are your temps in Safe Mode? What are they in your BIOS Setup Menu? Note when checking temps in the BIOS Setup Menu, your temps should be about as low as they can go because running the BIOS Setup Menu is about the least demanding task we can ask of our systems.
Finally, I recommend running (at least while troubleshooting) Gigabyte's own HW monitor, EasyTune6 (as found on your motherboard utilities disk or from your motherboard's download page, then check the HW Monitor tab. If your System temp there is show as high, then that's a problem as you can expect Gigabyte HW monitor properly sets reading to sensor.
