host4u wrote wait quick question 2 umm i have a xenon with no led or fan mod noda have had for bout 2 yrs and i use it ALL the TIME because its fun but it hasint rrod i guess i got a really good one right??????

Wow dude, I can't believe you haven't got RROD, especially since it's a Xenon

it all depends as i boosted my fan speed to 90% and i play it for an average of 2hrs and sometimes 4hrs, nothing so far, buts its only been a month, but my room is always very hot for my whole life, so it depends if you get a really good one.

i can play mine for hours an hours. Ive had it on once for 15 hours and it stays in the 50's for the gpu and in the 40's for the cpu. The only upgrade its got are whisper fans.
Guess im one of the lucky ones

If you have a 12 volt fan, it could last for 10 to 12 hours.

If you don't have one, it could last for about 5 to 6 hours.

Fracious

All depends, just make sue it doesn't mke wird sounds, and idk 4 hours maybe, then ake a break

Depends how cool you keep it and the condition of the board, I wouldnt expect too long, but some Xenons exceed their life expectancy, I had some that last 5 minutes and some that last 1 year...

Lol at the 1 hour comments!

If you don't have the 12Vfan mod, use FSD to up the fan speed. Then you should be good for a while, just keep an eye on the temp, if it does start to go up, just take a twenty minute break, go have a cuppa or something

as long as you want lol

bit of a dum question

Quite a long time, but just don't let it overheat.
