A new CPU cooler will only have a limited effect. It's the fact that the CPU uses solder and not paste that is responsible for the problem. That being said, switch it anyways, as the stock cooler isn't good. Even assuming an ambient temperature of 22C, and no overclock, the stock cooler will throttle under IBT.
82C is pretty normal for CPUs that don't use solder and use paste. You'll have until I believe 105C until shutdown, and throttle a few degrees below that. The HW Monitor is likely correct.
Only the HEDT CPUs come with solder these days. The other option is to switch that 4790K and the motherboard for a 5820K and an X99.
I reseated the cooler and replaced the paste with some mx-2 I borrowed (it was almost 2 years old too, does this have any impact ?). Temps went down by a few degrees but that's all, although now I'm measuring with higher temp in my room than yesterday since it's 5 PM and the day is hot. The results I gave you were from yesterday night.
I'll replace the cooling since 3 out of 10 heatpipes on my TR120 are rusty. One is real bad, two other have 2-3mm stains. Must've been from the time I spilled the coffee on my PC, might've been a few drops getting inside and landing on the pipes.

26c right now. 60c is what I'd consider hot in a game. This is at stock settings with a H100i. Ambient temperatures are 70f/21.1c. Sounds like even your ambient is high, or, you need a better cooler. As for stress testing, I've only used approved stress tests such as "Asus RealBench", and "AIDA64 ". Prime95 and intel burn will run these CPU too hot and was not recommended last I checked.
comparing a 240mm CLC to a 120mm air cooler, I'd say 20 degrees difference in gaming temps is about right given the fact it's around 25 degrees in my room (possibly more). Idling at 31-35 (coolest to warmest core). Our delta temp in idle seems not so different.
Can't wait for my Noctua D15S, love the looks of that cooling
edit: I told you my idle went down a bit, now get ready to hear this. In FC4 I'm running below 65 all the time, I was hitting 84 in the same game yesterday. That's actually the same as my 3570k 4.5GHz 1.264v Boy, did I screw this up yesterday
HWmonitor shows max temp of 80 degrees on core 1 but it must've been a short spike cause I saw nothing higher than 65 in afterburner OSD.I suppose those milisecond temp spikes are a thing on Devil's Canyon, only yesterday they ranged from 92 to 98 degrees
