I have a reference 670 by msi, im thinking of asking dwood to make a bracket with a fan bracket attached, but im not sure if itll be ok. If someone here can confirm that itll be fine, ill go for it.

Sure, Just make sure u have some airflow from casefans or whatever running over them. If not, they are no good smile.gif Hot air will remain there if u have no airflow.

Makes sense. The video DAC (digital to analog converter) will draw extra current. It's very likely shut down for DVI or HDMI.
The extra processing power will also raise the temperature.

I have always kept the original base plate on the card as it is also a heat sink complete with the heat sink tape/pads. It fits like a glove, of course, and eliminates some of the worry (and fun).

Heat sinks just make it easier to catch the wind. Some chips may be awkwardly placed for a small individual heat sinks. Some parts would not have enough surface area without a heat sink.

No matter what the model, or the method, it will require some air movement to carry away the heat. It doesn't take much air movement. If the VRMs (buck switchers) are 80%-90% efficient, you got roughly 10 to 60 watts plus the VRAM heat to get rid of.

that explains that then i think, b/c i started noticing the temp increases after i got the second monitor.

i dont game on the two screens at once tho, just use 1 still.

always use dual monitors. 27" widescreen primary and a smaller 19" square one for extra info and all. When I am gaming on my primary, i got hwmonitor open on the second one for temps and sometimes ventrilo or teamspeak or so...

yeah i have the second monitor open with a browser and some widgets that track CPU and GPU usage/temps. makes multi-tasking a million times easier

Very well, my heatsinks should arrive tommorow, I am thinking about reducing the voltage of my fan currently cooling the VRM's even further. My case is a Define R4, with 2x 140mm Fractal R2 fans, at 7 volts they produce a very decent amount of air, and 12 volts is just amazing, not sure if they can reach my VRM's, since the air is blocked by the H70 waterblock.....

U have air intake in the front too right?
Those big 140mm's should be able to create enough airflow even around the H70 waterblock.
