5090PC with custom loop suggestions

[DomPC]

Budget (including currency): 9000USD

Country: Washington 

Games, programs or workloads that it will be used for: Blender, MSFS2024, GTA, Cyberpunk 2077, etc. 

Other details (existing parts lists, whether any peripherals are needed, what you're upgrading from, when you're going to buy, what resolution and refresh rate you want to play at, etc):  I have specked out a custom loop with a RTX 5090 and ryzen 9 9950x3d.I was looking for some feedback / anything I have missed or might be incompatible. Thanks! https://pcpartpicker.com/list/prHW6Q

1. Get a native 2x32 kit, youre not going to have fun balancing those 2 kits to get it to run at full speed. https://pcpartpicker.com/product/j7XMnQ/gskill-trident-z5-neo-rgb-64-gb-2-x-32-gb-ddr5-6000-cl26-memory-f5-6000j2636g32gx2-tz5nr
2. You can only fit 9 fans in the O11 Dynamic. Pick one or the other between RGB or the iPPC fans. And even then, considering all the money, i would consider other alternative RGB fans for maximum performance. Consider something like Phanteks D30 line or Lian Li's own SL line. For the Noctua iPPC alternative, i would recommend the classic on this one, Arctic P12 PST. There's also P12 Max but the price bump is going to be noticeable because AFAIK Arctic doesnt sell 5 packers of that.
3. You can get away with 1x420 for those 2 CPU and GPU. Going 3 radiator is insanely overkill.

Okay that's sounds great, thanks, but I was thinking to go push pull on the radiators, if I do the radiators push pull for the top and bottom of the case and add a distribution plate to the side do you think everything would fit? Thanks so much!

But again, why? 1x420 is more than enough for cooling a 5090 and 9950X3D as long as you dont have cavitation in the system.

Pushpull isnt needed at all. Adds maybe 1c of differnce if you are using good fans.

 

Prime tip with a loop. DO NOT make it more complex than it needs to be.

 

Secondly DO NOT!!!!! get software controlledpumps or fans (speed) throw that icue pos thing against concrete now.

 

3rd stick to one brand for rgb. At most use multiple if they support the STANDARD rgb connector

2 radiators would most likely perform better and I have a high budget. I can use one radiator but is there anything else I would need? THANKS A LOT!
