So I have a question. I finally completed my rig and my new fans are "blinking" if you might. I only have a 530 watt PSU so I was afraid that I didn't have adequate power. So my LEDs in my fans will now run at max brightness then flicker down once in a while under load. Not shut off, just kind of lose brightness. I am also running a FAM controller. Is the fan controller, fans or the PSU to blame? I'm betting the PSU and is it a negative to run near max load consistently? I don't care if the PSU dies after a whole. I just don't want to blow up my CPU or something.

The leds on the fan only eat a little voltage from your PSU. I think it's the fan controller's fault here. You also plug a power cord from the PSU to the fan controller right? Try changing the molex connector.
If its a known good brand psu you will need a huge gpu to max 530 watts out or two ordinary ones. I doubt your new psu is at fault.
