I'm not sure if anyone else is having PC issues.  Mine was making a racket when I was rendering.

My PC is an ROG mother board, fast fast fast 16GB RAM, and a 3.8Ghz processor with a stock CPU FAN, and Geforce 560Ti (2GB) video card.

The stock fan would go into overdrive when I was rendering.  Given that my last bunch of renders are chewing in excess of 10GB of RAM, with FLM saves > 1.2GB, its no wonder my PC was chugging...  for 3 days through some of these renders.

 

I just upgraded to water cooling. I put in a Corsair H6O. ('cause thats more than H2O?)

Overall my PC is louder, but it hardly breaks a sweat when I'm rendering. CPU temperature is topping at 70C and holding there.  The loud turbo fan sound is long gone.
