Once the 5710 is mounted the fan can be reattached. Because of how it mounts you will likely need a small phillips screwdriver in order to reach through the top hole to the screw on the bottom. After the fan is replaced the video card can be reinstalled. On an SLI board the card is much closer to the CPU socket than on most non-SLI boards. There weren't any clearance issues but if you have a GPU cooler that wraps over to the back side of the card you may have to install the 5710 fan on the opposite side of the heatsink. It's nice that GlacialTech has thought ahead and provided holes there.
The 5710 could be rigged for either a push or pull configuration however I reinstalled the fan as it was received, pushing up through the cooler towards the top of the case. On some motherboards the socket mounting may allow for a sideways flow, and the cooler could be installed so that air is directed through the fins towards the exhaust fans at the rear of the case. You have several options here so although I did not perform any experimenting to see which method might work best, you may want to. The only thing left to do is plug in the fan. Nearly all motherboards should have at least a 3-pin connector for the CPU fan and the current draw on the Silent model is very low, so there should be no problems running it from the board. The PWM fan includes a 4th wire for the pulse width modulation signaling, if your motherboard/BIOS supports this. PWM allows for smart fan control and enables you to specify certain temperature triggers in the BIOS to tell the fan when to turn on and when to ramp up speed to counter rising CPU temps. This is very useful for providing an automatic balance between silence and performance when needed.
Continue ahead to testing and conclusion.
