Is it safe to leave the PS3 folding for 24/7?
- Yes. There's no indication that the PS3 has problems over long periods of folding... but of course, you should ventilate the darn thing so it won't overheat.
- No. It shouldn't need a cooling period. You know that whirring thing? It's a fan. It regulates the internal temperature. [note: PS3Fanboy added some "attitude" to this response, because we like attitude]
- The Cell processor. Luckily, it's a high-performance processor built for things just like this. Folding@Home shouldn't have any adverse affects on the PlayStation 3's stability.
That's all that we think pertains to running the program on your PS3. Don't worry, guys! Your system is completely safe and that's a good thing. Waiting for those warranty replacements or whatever aren't the best... plus you only get a refurbished system (read: previously broken) instead of a new one.
