In my view after playing with a simple cooler is that using it to cool a small desk area not worth the effort.
To get any cool one has to dissipate a huge amount of waste heat. In your case this waste heat build up will end up overwhelming the cooler and make your shop hotter then before experiment. ?

Hi abpccpba
Welcome to the forum! I moved this to the "Electronics Components" section as it really isn't a robotics post.
I'm sure you're correct, the Peltier Effect device was an impulse buy that I couldn't resist. It was 15 Canadian dollars on eBay, that's about 11 US dollars, and it included a 5-volt, 6-amp power supply and power cord. The power supply is worth more than that, so even if it turns out to be a flop I still have that, as well as a few fans and a heatsink!
But actually, I still have high hopes for it. If it can blow cold air on my face it would be a success. Even if it's a complete flop it will make for an interesting video and article.
And it isn't for the workshop - it's for my computer desk. So it's in a much larger area than the workshop.

I use a similar setup to cool my astro cam. I use an old CPU cooler and a temp monitor board with a relay to control the fan. It works ok but I'm thinking of a water/Peltier system now to get the vibration of the fan off the camera.

I agree with abpccpba.
A long time ago someone suggested buying a cheap stand-alone air cooler. But when I explained that unless the heat is dissipated outside the room that you are cooling, you are just adding to the heat in the room due to the conversion of electrical energy into mechanical energy that is driving the fan.
We quickly forget the "laws of conservation of energy".
It might just be a better idea to blow air into the room with the intake on the north side of the house.
