Do you have any side fans installed? You can also try to run the heatsink fan as pull and leave fan top side panel off too allow air to pass through.
Lower side is mainly for GPU, which is in the wrong spot and mostly blow out the rear.

If you can mod your case to remove the optical bay and affix some more fans in that area, which modding the optical bay plates so air can get through.

the one behind the cage only has 2 ssd's and 1 hdd in front of it and I can feel a good amount of air passing through.
I just starting having the temp problem the last few weeks, thats why as other have suggested I am going to replace the cpu thermal paste.
I even removed the restrictive front grill years ago, and as I also said everything else is running cool.

Low cost and easy way to monitor cooler intake and other case temps is something like this.

I have added a new fan which lowered my gpu temp 4c which lowered the cpu 1c due to the hot air rising up from the gpu to the cpu cooler is not as hot with the extra fan, now just waiting on the new
thermal paste and I should be good.
I will report back on my results Saturday as the paste won't arrive until Friday evening.
thanks for everyones input.

Edit: if anyone would like to see these are my idle temps.

I really don't think new thermal paste is going to change anything significantly. Applied thermal paste should last well beyond 3 years if the seal between the CPU and cooler isn't broken. If you removed the cooler in the last 3 years and didn't reapply paste then you should have.

Also I think people get to up on arms over fan configurations. The air moves very fast and with how open your case is and how many fans there are I don't think this an issue. Maybe you could have better "balance" of intake and outtake but, before somebody complains, he was fine not too long ago.

True the heat sink seems very unlikely to degrade and it is good to still check paste and the fans, but it remains a new cooler would like solve the issue if all else fails.

Think long and hard on what changed. For example, new hardware or maybe ambient temps.

You are entitled to our opinion.
The facts are that after a couple of years it is not uncommon for TIM to degrade. Remove and replace generally lowers temps, sometime by a large amount.

How many fans and how fast the air moves does not mean the airflow is optimized. But the fact he had good temps before with same fan setup indicates case airflow is okay.

The chances of it being cooler degrading are 1 in a 1000000. Cooler may be dirty and a good washing may be in order. A couple of years use in a house with smokers can put a film on fins that requires hot soapy water washing. I often do this in kitchen sink. Fill sink with hot soapy water and soak cooler in that for awhile .. agitating it every 5 minutes or so, then rinse. A final rinse with distilled water helps eliminate water spots when dry. (I have plenty of distilled water from dehumidifier) Dry with a hair blow dryer or set in a nice warm place.

The cooler has been in place for 3 years 4 months, as for the paste issue I was told directly by a Noctua tech that thermal paste will and can go bad after 3 years of constant use.
My system runs 24/7 and half that time is Folding, I only turn it off once a year when I go on vacation.
Nothing has changed in my system except a new gpu which runs 18c cooler than the gpu it replaced.
the temp issue isn't really severe as the temp change has only been around a 10c increase and only while folding, I believe replacing the thermal paste is a smart decision and I will be doing it Friday evening when the new thermal paste arrives via UPS. and I keep my system very clean and there is and never has been smoking in my home.
I have also added a new fan to my setup, it's the one sitting on the hdd rack and is pulling air from the front intake fans. there is one behind the hdd rack and the rack has large openings for air flow and there is only 2 small ssd's and 1 thin WD VelociRaptor hdd. Edit: when I have the cooler off I will give it a good inspection and make sure it's super clean as the style does make it hard to inspect when installed, I own a data vac and I use often as I hate anything to be dirty, including my vehicles and home.

Didn't know you replaced the GPU! That could be the reason for your temperature increase as well - your new GPU blows heat into the chassis with its aftermarket cooler and axial fans. Perhaps,you were using a "reference," blower style GPU with a radial fan that would exhaust air out of the case before?

I mean, of course replace the TIM, but this may have had an effect as well.

No the gpu I replaced was a Gigabyte G1 Gaming GTX 970 which ran 8c to 10c hotter. it'salmost Friday, tracking shows my new thermal paste is in my state now so sometime tomorrow (Friday) I will get it and post my results.

One thing I did which you might consider: remove the rear grill. This is the 2d case I did it with. The 1st case is in item 2 of my sig.
