This sounds like a good idea, but would like a switch, as fan is very noisy to have on all the time

right, the fan may be noisy but remember it's a necessity, if you don't turn it on, you could fuck your car.
buy a switch, wire it up the the plug at bottom of fan on LH side if you at front of car, wire that up to battery, with an in-line fuse, add a fuse that suits and test your new fan using switch.
good luck, i prefer using the automatic 96 degrees computer system though.

I would prefer it worked by itself too, how did you get it to come on at 96 degrees

As he said - it's automatic, it's how it was designed to work from factory, so as long as you have everything working correctly and connected up as standard, it will come on between 96-98 degrees.

Oh ok, I always thought it kicked in later than that anyway. What should I start with?

You unplug the switch and bridge the two pins on the plug.
It will spark and your fan will spin. You then know the fan works.
Replace the fan switch that screws into the radiator and it'll come on at 96/98 degrees.

If you want an in-line fuse then try a motor shop, maybe an audio shop will have one but make sure it's 12 volt wire and not speaker wire or owt dumb lol

trust me mate, it's an old corsa...it does overheat in traffic. as long as the fan kicks in at 98 degrees latest. It's fine...if it doesn't, that's the only reason you need to wire in a fan unless a big c20let is melting your fan or some shit but i doubt that.
Let your car idle until 100 degrees. If it actually reaches 100 without the fan coming on (you will hear it), then turn your car off immediately. You'll most likely need a new thermo or some kinda sensor. Don't worry about wiring up a manual switch for the fan because how fucking annoying would it be to have to constantly switch it on and off?
Just see if your fan kicks in before 100 degrees, if it does...all is perfect. They are old cars and do 'overheat' in traffic. Despite it being called overheating, the fan kicks in to make it cooler, it cures the problem, although it's not a problem. Basically if your fan works, don't worry yourself. If it doesn't, I'll draw you a simple diagram. It's not difficult. Just think about it...The plug goes into the fan...cut the wire, through rubber grommit, put a switch on dash, make sure it's a switch, pos, neg, switch wire, wire it onto the battery with a fuse in the middle so you don't fuxor your fan....thinking about it though, your fan has a built-in relay. So if you wanted to do it you will probably have to even build a relay into the wiring..not worth it IMO.

Just repair it before you think about making a manual switch, what engine is in your corsa?
check the relay and fuse
