I'm planning on building a gaming PC to run at around 9000' elevation in CO.

An interesting problem I discovered with my gaming laptop is that at that elevation cooling is a real problem due to the thinner air.

So I'm going to build a desktop system for this location.

I'm going to approach this from two angles. One is I'm considering liquid cooling, even on the GPU, the other is a computer that is more thermally efficient due to lower power consumption and lower power draw. Or I could just run a massive air cooler and accept the earlier CPU throttling.

I'd like to throw a big GPU at it. Maybe a 3080 or even a 3080ti but I'm worried about temps. Anyone have any experience with liquid cooling a high end GPU?

Pretty confident in my building skills. Just want to make sure I get quality components that can do the job.

All input is appreciated.
