Well, that's your issue. Rear locations are for exhaust. Cooling flows from front to rear. Front, bottom and side locations should be used as intake. Top and rear locations should be used as exhaust. The only exception is when a radiator is used in the top location, some configurations use those as intake. Aside from that, there should be no deviation unless you have a top rear mounted PSU, which most case designs do not use anymore.

I'd move the radiator to the front or top, configured as intake in either location in a push configuration. Use the front location if at the top, bottom if at the front. Use the two remaining top locations as exhaust if top mounted with the rear as an exhaust as well. The rear exhaust is the most important...

Radiator is in push configuration at the rear as an intake. Enthoo Luxe case. The fan that's used with the radiator is the original one that comes with the H80i. 2 140mm and 1 120mm exhaust on the top of the case. one 200mm fan intake at the front and 1 120mm intake at the bottom.

Prime95 I usually just run a blend test. I'm new to CPU overclocking though so I just followed the settings from here.

Though even under Asus automatic overclock settings, my idle temps still reach 80+ 90+ during Prime95 testing, and 40+ on idle.

Use the two remaining top locations as exhaust if top mounted with the rear as an exhaust as well. The rear exhaust is the most important fan in the case and is the area of the case where the most heat tends to accumulate due to the CPU, GPU and PSU heat all rising to that spot. This is why even cheap cases that come with only one or two fan locations will ALWAYS have an included fan in that location.

OR, leave the radiator where it is but flip the fan as an exhaust. It's not the most efficient method since you'll be using already heated air to run through the radiator, but plenty of systems use it that way. I'd personally put the radiator in the front or bottom, which is where the coolest air will be found, and use all the other fan locations as they were intended to be used with front intakes and top/rear exhaust.

Well I'm gonna upgrade my cooler to the 280mm H110i so I would convert the rear fan into an exhaust instead. Probably going to mount it to the top of the case with a pull configuration as an intake so that I have positive pressure in my case. Will update once I have the parts. Thanks for your help
