hello folks,
i just realized that my stepper drivers, vfd and PSU are running at their peak temperatures and the stepper drivers trips due to thermal limit also. I touched them and they were really hot (i have just replaced my psu power mosfets that i think got fried due to heat).

i have tried using fans and filters but no luck ( a lot of conductive dust is always around it that blocks the air filters so fast) I am thinking about a mini Air conditioner now as used in commercial cnc machines. I just came across this
Mini USB PC Fridge Beverage Drink Cans Food Cooler New! | eBay

it is a 12V air chiller based on "peltier thermoelectric coolers". Will it work? what you guys think? Any web links for cabinet coolers below $200 ?????
Not all my electronics have thermal protection and i run the machine regularly 8 to 9 hrs a day. So be fast this time please (before i fry something else)
