okay, i had my 360 for 2.5 months now. i got it off locally as a modded system. he did the xclamps, 12v mod, fan shroud. well it worked for 4 days, then rrod. i opened the system open, he already done the xclamps and 12v mod, (he didnt tell me, i found out myself). well i redid the xlcamps and did the baking trick. it worked great for 2 months.
august 1st, rrod. did the baking trick, worked for 2-3 days.
august 6th, i did some radioshack shopping. got me some fans, ram heatsinks and a pc fan controller for my pc
i took out my dvd rom outside, i extend my power wire, bought a sata cable (6ft). i redid the xclamp, a snug tight torque on it. i had a fan on the cpu and gpu. worked great for a week. just one freeze during that week. hours of fun
yesturday, rrod on me playing gta 4. i probably was playing for almost three hours. then the screen turned completely black. rtight on, im like WTF FAWK U 360
wat i noticed during these xclamps. if u do too tight of torque on the gpu, u will get artfiacts and a checkered screen within 10-30 mins. im doing the xclamp version bolts on the mobo not through chasis.
right now, i disconnected my exhaust fan. having only a fan to the cpu and no fan to gpu. having it idle. it might freeze within 45 mins or so.
i also had a fan on both gpu and cpu, had gears of war on. just replaying the intro video, the screen starting gettin artfiacts. can too much gpu cooling not good?
ill be doing some more testing and what not. please chime in. thanks
