I am looking to upgrade my existing AMD R7 3700x with RTX 3090 and 750w PSU to a 5900x and 1000w PSU.

I'm worried about the increased temps and would like to upgrade my air cooler from my Alpenfohn Brocken ECO Advanced CPU Cooler.

Is a Dark Rock Pro 4 a worthwhile upgrade? I don't know enough about PC building to go down the water cooled route.
 
The Dark rock pro 4 is an excllent cooler aLong with the nocthua nh d15 are probablly the best 2 air coolers, they are 165mm+ tall. The Alphenon brocken 3 is a beast for the money and is within a few degrees of the above.

What case fo you have ?

I have a I have a Lian-Li Lancool One Digital Midi Tower.

I am worried about the size of the Dark Rock. Do you think I should just stick with the Alphenon? I get like low 70s when gaming at the moment.

Your case takes coolers up to a 175mm tall so no worries there but the Brocken eco is cutting it close for a 12 core cpu. Try it see what temps ypu get.
 
So I have my new psu, cpu and cooler. The cpu seems to fluctuate wildly when idle (45-60) and went to 89 during a back-to-back Heaven and Cineworld R23 bench (room temp was 26/27 though). Are these normal? I feel like I installed everything correctly.

It is normal for a 5000 series cpu. Welcome to Amd. You will find if you leave it to idle and finish any background tasks it will settle but minute you load anything it goes up and down and can even cause the cpu fans to ramp up and down, so you may want to set a fan profile that is not annoying on the cpu.

When gaming it ramps up to 90 and sits there. Is that normal? With a Dark Rock Pro 4 I was expecting better performance.

90 is too high. Could be the cooler isn’t installed quite correctly or the fan profile isn’t working properly.

Thanks @Trick

I had someone from Fiverr look at my pc. He has optimised it, overclocked it, and changed some volatges. Up shot is better performance and temps have dropped to 45-50C at idle and 79/80C in game. I still feel like this is high for the cooler and I have 3 front intakes, 1 rear exhaust and 1 roof mounted exhaust fan.

The fan profile seems fine, so I can only assume it's the cooler? It looks fine to me and there is thermal paste on the bottom, suggesting it has contact with the cpu fine. My concern was it is very snug with the gpu and ram. Is it worth me trying an AIO cooler?
 
If you are using a quality air cooler than an AIO will only improve things marginally. Idle temps will be lower for sure but the temp under load may only drop slightly. On my 5900x it runs at 72C and 5950x it also runs at 72C and I use an AIO when playing BFV. As many people have said these chips runs hot and even though it does not sit well with me (although the 5950x doesn't bother me as it has more cores/threads) this is something you will have to accept or not.
 
Even using a custom loop, you won't see low temperatures. Sorry.
My 3900x which runs cooler than your 5900x wasn't any better from a triple 360mm rad setup than it is with the Arctic Freezer II 360.
Even if doing a custom loop for the CPU, the only way to reduce a bit of the temperatures is undervolting or similar thing for 5000 series Ryzen (voltage curve I guess).
 
I recently changed from a noctua NH-D15 on my 9900k & 3090 to a 280mm AIO Kraken Z thing I think and my temps on both cpu & gpu reduced significantly but I am sure it was due to the massive amount of space that the noctua took up trapping hot air
 
The AIO works as exhaust, and pretty much all heat is dumped straight of the case, unless for any odd reason yours is as intake. 99% of the cases, I would use the AIO as exhaust, at the top.
