Radeon HD 6850 & 6870 reviews...

1-Hot air gets sucked in by those big fans, and heats up you GPU too. So it's debatable if you get a cooler GPU.
2-You NB and SB are really closed by, and they get toasted.
3- Hot air will limit your OC on CPU, for sure, and would affect your RAM-OC too.


Better case-ventilation needs more fans, and it means more noise, and we should try to eliminate the source of heat for 24/7 first, and then add more fans.

1. You don't have hot air with 3-4 12cm fans, well pozitionated, they will suck fresh, cold air from outside the case, and exhaust the hot air.
2. P55/H55 for example don't have NB and ICH10R on 45nm is a small and cold chip. And also applies p. 1.
3., see p. 1 for Cpu, and if we speek about DDR3 memorys, DDR3 memory is very cold compared to DDR2 so no problem.
4. There are 1200-1300RPM fans with 21-26db noise, so there are very silent, silent than your VGA.

Open cooler are in VGA industry from many years, is not as they introduced them, now.
It's not about cooler , it's more about TDP card, a GTX 480(TDP 250w) open cooler produces much more heat, a GTX 460(TDP 160W) produce a little. And you not judge that even with EE cooler you dump heat in case because PCB is hoter, and it heat the air in case, to.
With an open cooler you have lower temperatures of the pcb.

Sam_oslo, you don't keep the gpu load to 100%all time, 24/7, you use him only when you play games...In idle the voltage of Gpu lower from 1.0v to 0.875v, i have with my GTX 460(Gigabyte-windforce), 35C in idle, lower temperatures than on cpu with stock cooler.
And the heat will vanish when you don't play games, so your sistem will not increase in temperature forever. Temperature into the case will lower to normal in idle periods.

Please try to keep it real, and on topic, and tell me why do you want that hot air inside the case when a good cooler could dump it outside?

For an user with so many posts, you speak nonsenses. GTX 460 isn't 8800GTX...or 9800GX2....or GTX 280...
And you are offtopic, too...this thread isn't about vga coolers. Evga has some GTX 460 external exhaust cooler models(EE), buy that to be with peace in your mind.
