I'm using Asus P5Q Pro in Cooler Master Elite 335.
I know Elite 335 is not exactly easy in cable management but I'll have to do the best I can.

OK, my question:
1. I've tried to mount a 40mm fan on top of the NB heatsink using screws but I found the fan is a little bit bigger than the heatsink so I can screw the four corner. Is there a cheap and simple way to mount the fan? Is it recommended to mount the fan sideway with cable-tie?

2. Since I have no place to hide those cable, is twirling the sata cable a good idea so that I can make some room for psu cable?

3. I salvaged a fan speed controller from my old Thermaltake Volcano 7+, it has a low>medium>high switch and a spliter for motherboard fan connector to monitor fan speed. May I use this controller on any other case fan or only certain type of fan?

4. I have my SB X-Fi Titanium Fatal1ty Pro (the one with EMI shield) sitting extremely close to my HD4870 in 1st PCI-E x16 slot, is this bad? Does the back of graphic card PCB need to be cleared for better cooling? Shall I move the graphic card to 2nd PCI-E x16 slot?

5. Which is better to connect the case fan? Motherboard fan connector, fan controller or psu directly?
