theory: f(x) = x
practice: f(x) = -8 + 16/(1+e^-10x)
Maybe it’s just mine but can we agree that a lot of showers do that?

Get a thermostatic mixer valve. You’ll never go back…
Remember when those boring old two-tap showers never had this problem?
Turn your hot water heater down or replace your shower valve
No its just that our ideal water temperature is very very narrow
You can plot my shower in three dimensions with water pressure.
The hotter the water, the weaker the pressure.I drop the pressure, the water gets hotter :)
Based on the sounds from my computer, that’s exactly the same curve the fans on my GPU and CPU uses, except for the X axis being temperature starting from 0°C going to 100°C and Y axis being fan power in percentage.
I think the problem there is that GPU temps are spiky themselves.
True. But I also tested when my GPU fans would turn on and it seems like the cut-off point was 45%, below that and they’d just stop completely. And normal idle temperature is around 40°C, and with the curve on the left it makes sense that even a 5°C increase would rev the fans up from 0% to 45% making it sound like a jet fighter about to take off.
If you’re on windows, look up the program/github fancontrol. Nice easy way to adjust the settings, set custom curves based off different temp sensors (and combinations of temp sensors) all without having to muck around in your BIOS.
A lot of showers need a new mixer valve…
I have this issue in a home built just barely pre-lockdown. So the issue isn’t wear and tear.
What should I be looking for to fix this?
Sometimes even new(er) valves fail. If you have hard water then that is plenty of time to mess one up. In a best case scenario, you can lookup your make/model of faucet to buy a ‘cartridge’ for it and find the instructions on how to replace that. In more extreme cases / poor designs, you could have to tear into the wall and replace the entire thing.
