CPU Heat spikes and also new case/ cooler compatibility

I recently upgraded my computer to an I7 7700k and MSI z270 M5 Gaming motherboard.
I never bothered to upgrade my cooler which is a Corsair h80i (not the v2 (the cooler is about 4 years old)).

I don't understand the temperature sometimes as when it's idle it will be between 40-50 and it will spike up to 80+. This is when it's running at 4.2ghz - not even overclocked. When I do overclock it ends up spiking up to around 91 degrees. Whilst gaming I get temperatures between 70 and 80. is this normal? I reapplied the thermal paste for my cooler and it didn't make much difference in temperature.

Are these normal temperatures? If not, should I upgrade my cooler? I want to get the lowest temperature as possible with an AIO cooler. Would more intake/ exhaust fans work?

I was looking into AIO cooler upgrades and I would prefer to get a 240mm/ 280mm RAD that I can mount at the top/ front of a case. However, I have a corsair 300r gaming case (mid-tower) and the motherboards size does not allow me to mount a 280mm / 240mm to the top. And It would require modding to install it at the front.

I'd prefer not to purchase a new case just to install a bigger cooler.. My PC is underneath a desk in a corner just so you can get an idea of the airflow. Currently the fans are setup as 2 front intakes and the back exhaust push/pull radiator. Would buying a new 140mm back exhaust rad suffice or would it be better to upgrade to a 280mm? Such as a corsair h80i v2. are there better ones? This is all dependant if the temperatures are abnormal.

If you suggest a 280mm rad - are there any mid-tower cases that provides enough room from the top to the motherboard that will allow me to install a radiator of this size to the top of the case.

Thank you for reading! Any advice/ information would be greatly appreciated!!

To address temps first, 90 is pretty high. Anything above a 75, in my opinion, is pretty high but when it hits 80-85 or more it actually becomes a slight issue. It will cause thermal throttling which will pretty much make your cpu run worse than it normally should because of inadequate cooling. As for the case fans, they seem fine. More than adequate. I would suggest getting a better air cooler but if that fails then look into water cooling. This does seem weird as it is a 7700k not even a ryzen. Either way, try getting a hyper 212 evo. It should serve you well both with or without overclocking.
