vTxMoDz wrote so heres the problem:

I turn my rgh on, it works fine, i can go into xex menu, i can change the dashboard,
but after about 10 minutes the fans start to go very loud for about 5 seconds then it goes straight to 2 rrod,

i heard its something to do with the HANA chip by the fans,

just need to know the problem so i can sort it out,

ill give a free 10th/unlock all to who ever gives me good advice.

You need a reball of the console because its overheating. Have you tried replacing the thermal paste?
