It sounds like you have a similar setup to mine, except I don't compile all the time so the CPU fan hardly ever makes noise (it runs at a low speed all the time on mine)

Another alternative would be to locate it elsewhere in the house, and either do your compiles off a low power PC/laptop via ssh to the "server", or run wires to it. You can use ordinary twisted pair for HDMI and another one for the USB to a USB hub for keyboard/mouse/etc. For an unrelated purpose I bought two super cheap little blue dongles off eBay with a cat5e connector on one end and HDMI on the other, and they work fine for 1080p60 at 60 feet or so. Amazing how well they work for something so small and costing under $10. You need something more expensive and cat6a for 4K, and might need two wires, but its doable.
