Looks awesome. I'm going to have to get some of those. I never run my Sanyo Denki's higher than 5V anymore, so I might as well downgrade to something a little quieter to go with my new MCP350 that should be arriving shortly.

So are you going to integrate a fan controller into the box you're making?

I haven't really deceided entirely yet, but I think I'll probably run a power line from the case to the radiator box, then split it 4 ways to power each fan. I'm going to try the fans at first with full 12V to see how loud it is (they only spin at about 1300 RPM at 12V). If they are too noisy, which will probably be the case, I'll add a 1W Zener diode on the 12V line on each of the fans to drop their voltage to 7V. Those fans have been reported to be completely silent at that voltage, though they don't move much air. I'm probablt going to try to figure out a way to integrate a pump enclosure in the radiator box as well to make things a little neater, quieter, and more compact. I haven't really decided on which pump to use, though I think an Eheim 1048 will do the job, and I can always add another one inline if I switch componentas and need more head/flow. I would use a Laing DDC, but I hear those are not quiet enough for my application.

How do most people integrate power for multiple fans into their radiator box? I've considered using a small independent power supplywith a fan controller, or just running power from the PC to a fan controller. I think the diodes are better though, as they're cheaper, and I don't think I'll ever change the fan speed once it's set to a quiet level.

Used a 12v brick from radioshack in series with a pot. Originally it was going to be used for powering 2 80mm fans. Think the max amperage it could put out was like 1A. Course thats passive now so all that thing is doing is powering an LED in the power switch :D


Im sure you could find a 5v brick that can give 1-2As just as easily. Just put them on 5v from a PSU and make sure they move enough air.

I did consider using a small brick like that, among other hare-brained ideas like installing a small power supply in the rad box :p I've finally decided on using a 3.5 inch black Vantec Nexus fanbus. I'll run the power along the coolant hose between the PC and the radiator to help keep things clean-looking. The benefit here is that the fans will tun on with the PC, and I can control the speed of each fan individually. It's more expensive than using diodes, but it offers much more control over fan speed/noise.

Those damn Yate Loon fans are out of stock everywhere. Stop taunting us with those kick ass pictures. I might have to settle with the medium speed transparent blue Yate Loon fans (1650rpm, also used in Forton quiet PSUs) and just undervolt them.
