Alright, the pictures from my Sandy Bridge i5 2500K system :
The CPU heatsink - A CoolerMaster V6 GT :
This is a single-core multiple-finned heatsink with two fans - one on either side of it. The air-flow is from front backwards - air get sucked from the front, passses through the heatsink and is sucked and pushed away by the second fan on the other side of the heatsink, which in turn, is sucked by the 3rd fan fixed on the chassis at the back, and is pushed out.
And the views when I usually play at night with lights off :
The fan above is the same size as the huge fan seen in my classic system, which I posted in Marvin under Overclocking...Heat Thread.
It looks small here because of the relatively larger case. This casing also has another of that huge fan (without light) on the top, inside.
The temperature, after 30mins of playing Borderlands with crossfire enabled at 1920x1080 with all settings set to max (which will include the heat produced by the twin 6950s):
Though I am not a hardcore cooler, I'm still very much particular about the system and cpu temperature. I still haven't done any studies on the effects of temperature and multipliers and FSBs and so on, though.
The noise is remarkably quiet. It's even quieter than my classic system posted in marvin - mostly due to the noise produced by the socket 370 cooler's fan fixed on the socket 7 in that system.
