I did some digging up and found a article in a forum that discussed what the Nyko Intercooler does to your Xbox 360 power brick.
"All people who are thinking about the new intercooler what ever you do DO NOT BUY AN INTERCOOLER.....EVER! I have had personal expierence with the intercooler and nyko. First off let me say that the company nyko is a very bad one in general. They rush their products out to the public so they can make more money. But what they dont have is customer service! When i bought my 360 march of last year i had heard about the overheating problems and decided a month later that i would pick up one of the new intercoolers that nyko makes. I haerd great reviews about it and thought to myself, well they say it will extend the life of your 360 so why not? right i mean get the most of your money.
What nyko doesnt want to tell you is that every game console ever made requires a precise amount of watts/volts going into the system to power it. I believe the 360 takes about 110v to power it. They leave i think 1-2 volts of power to power any add on accesories such as the wireless adapter or to charge a wireless controller. But the nyko intercooler requires 3 volts! Exceeding the limit the 360 has to offer.
So in lamen's term, the intercooler was taking 1 too many volts away from the 360 to power nyko's fan that they had. So what happens is over time (about 4-5 months) the intercooler slowly starts to literally burn your 360! What happened to mine is i started to notice a burning smell in my room and what was happening is the ac adapter that the intercooler had had been completley fried. It was a charcoaled with black and then my 360 broke along with it. The technician said that the intercooler had fried my dvd power supply, the cpu processor itself and most importantly the ac adapter!"
I took mine off immediately. I only had it on my Xbox 360 since Wednesday. So just a warning throw those Nyko Intercoolers in the trash!!!!
