Yes, it is a Lenovo IdeaCentre H420. I will try the full load test shortly.
So, under full load (both cores, I did multithreaded WinRar, it gave 1.2MB/s in the benchmark), I could not hear any increase in noise.
I a completely silent room, you can hear the fan a bit, but the HDD is louder when it reads/writes
If you have any bit of background noise (TV, radio, people talking in next room, street behind window), you will probably hear nothing.
Well, the Sandy Bridge Pentiums are in reality 35W TDP parts, although for marketing reasons (so they can sell more expensive "low-power" CPUs), they are branded as 65W. There are several sites out there that investigated the actual power consumption of these parts under full load and the results were between 31-37W. This means they don't get very hot and you can probably even underclock them, lowering power consumption even further and consequently noise as well.
