Not sure about "good quality" but I've used one of these
eBay# 123242334050
It's been controlling the temperature of a small pot of water 24/7 for about 2yrs now.
That’ll probably do the job I’m putting my 3D printer in a enclosure so I just want a way to make shure it won’t over heat
I was looking at them but ideally it needs to be 12volt so it can run of the power supply for the fans and control them directly instead of constantly switching the psu on and off all the timeCould consider an INKBIRD ITC 308, I use it to control temperature of my beer fermentation. Uses a probe to detect temp and turn off or on cooling devices (fridge in my case)

So can you set what they come on at or notIn that case, you could just use cheap pwm temperature controlled fan drivers. Plenty on eBay, they're cheap, small and work well.
They come with basic control parameters so that they ramp up/turn off at different temperature thresholds. I've used a couple to aid a wind turbine inverter that was only passively cooled. Again, they've been on, 24/7 for, recon close to 5yrs now

I've had a look at the description but they don't say so my consern would be them cooling it down too muchSome, kind of.
They generally come with 2 or 3; 0/1 switchs that, given different combinations, allow different temperature control parameters. Have a look around, the descriptions may/should hint at what they do.
Think they're primarily used for cooling electronics though so I'd think a sensible thing to use in you design
No but I'd like a one where I can take the power of my printer plus if it's 12 volt it'll only be turning the fan on and of not the psu as wellThe controller doesn’t need to be 12 volt!!
