Koolance recently released an Xbox 360 version of their liquid cooler. The kit comes with everything you need to prevent your 360 from getting the red ring of death. It’s a hefty $289 bucks but for some, it might be worth the investment.
The Exos-LT liquid cooler is external. It requires some modification to your 360 internals and will void your warranty. It’s an easy mod if you have the aptitude but it’s a lot of hardware just to keep your system cool. Would like to see some temperature charts with the Exos as compared to a Nyko Intercooler.
