Higher ambient temps = Cooling fans less efficient? Liquid cooling necessary? Liquid nitrogen?

[HumbleWayfarer]

My desktop sits in a room with higher than normal ambient temps due to not having a proper ventilation system connected to the central A/C unit. I can't change this and window cooling units are also not an option. Right now it's morning, and the ambient temp is roughly 31-32°C. It will probably go up a few degrees by mid-afternoon.

I run an i7-4790K stock-clocked with a Noctua NH-U14S fan cooler, and under heavy gaming load temps would reach 82-86°C pretty regularly, and one or two cores had at one point reached 90-91°C. The GPU died a week or so ago overnight while not under heavy load, but it was a stock-clocked Gigabye G1 GTX 970 and would generally reach 79-81°C under heavy load. I am currently sitting on integrated graphics while I search the 1070-1080ti market prices leading up the 2080 release. I use this PC for gaming, video editing and rendering, and occasionally live-broadcasting while doing both of those things. I have a few photography lights that certainly add to heating up the room even more during those live broadcasting sessions as well, so I'm worried about doing some damage to my components over time.

In this situation, aside from lowering clock speeds, would CPU and GPU liquid cooling be the undisputably superior solution to getting cooler temps? Would cooling fans be innately less effective due to these ambient temps? How viable is liquid nitrogen cooling in a consumer PC in a hot environment (assuming I could find someone with experience to set up that system for me)?

Thanks for any guidance you can give.

Those are some really bad temps. Liquid cooling is definitely going to get it cooler, but not because of your ambient temperature. The effect that has on things is negligible unless conditions are really extreme. I still wouldn't recommend the upgrade to liquid for you, though, as your temps shouldn't be nearly that high in the first place. Noctua makes some fantastic coolers, and unless you have a crazy overclock you should be doing way better than that. You've reapplied thermal paste and whatnot, no?

I have not reapplied thermal paste since its installment. Do you think that is the likely culprit for temps that high, then? I'll shamelessly admit there's a lot of ignorance on my end when it comes to maintenance of components and I wasn't aware that paste needed to be re-applied at all. I will look at grabbing some Same-Day off Amazon and doing that this afternoon.

I guess I had just assumed the ambient temps were fairly extreme on their own. What about the GPU temps of 79-81C? I was reading through benchmarks on some of the current-gen cards and they seemed to be much lower than this even under really heavy load, and Windforce is a decent cooling system as far as I understand. Would liquid cooling a GPU be reasonable at those levels, or perhaps some other aftermarket cooling solution? I don't think that's what killed my 970 since it wasn't under load, but I'm just in paranoid mode because I did not expect to have the expense of looking for a new GPU this soon.
