I bought my XBOX360 in March. Been playing it a lot, and usually have no problems. Bought a NYCO INTERCOOLER for it after hearing how much they helped.
True, it did help keep it cooler..... Noticably so, but I started having probs not long after with the FANS not running right. They would occasionally "grind" and make odd nopises to where I'd just turn them off sometimes. This stopped a few months ago, and all was well........
Then, I got the "3 red lights of doom" Only happened briefly, and I was able to restart without any issues.
Then, the 3 red lights became more frequent, usually a jiggle to the main power would take care of it and I could get more gaming in.... Until last week, when the 360 went poof.... 3 red lights, no rebooting helped at all. So, I sent in for my return tag from Circuit City (I got the 3 year warranty) and they instructed me to pack it up, and send it back for a new one.

As I disassemble it, I pulled off the INTERCOOLER and noticed it wass BURNED. Yes, BURNED on the connectors... So thinkiing THIS may be the issue, I removed the intercooler, took some alcolhol and cleaned the XBOX contacts, and put it all back together (minus the intercooler of course) and have had ZERO problems....
I think I'll be contacting NYCO with this issue, as this could have been much worse. It could have seriously damamged my console, or perhaps even started a fire.
So if you have an INTERCOOLER, I suggest taking it off, and examining it for burns/shorts etc........
