Please tell us some basic information before asking for help:
You want to destroy it and you burn? give it to me instead, I don't want to root mine yet to play with the sources kindly made available by Asus, but I'm dying for it.
it would use a different cooling, when starting what would not be detected Asus fan would be a big warning in case of a ball fault turning on x mode without using cooling the warranty expires, so I think
You can if you want but I not recommend it because it can burn your internal phone
Can I know how to get around it? There will always be a better cooler used
