LOL- 29's would have been complete overkill. So you're only pushing 1000ma into the 5600K's? Is that with LDD-1000H's or are you simply PWMing the heck out of the 1600ma drivers that I sent you?;)

LOL- I'd been thinking that I'd screwed up by purchasing the 5000K 70CRI Vero 18's. Now with what you're saying- I got it right? I guess I'll hold off on those 90 CRI 5600K units for now.:wink:

There's no room inside the power supply for a larger fan. I actually enlarged the hole (meant for the stock fan) and bolted the larger 90mm fan to the outside of the power supply. I cut the power...

Gus-

If space permits- use all four fans. It may be overkill but a little extra redundancy is a good thing. If a fan were to ever fail, you'll still have enough air flow to adequately cool the...
