Well as some of you may know I've been playing with my PSU lately, sleeved it and added VRs to the voltage sense wires so I can change my voltage rails, and am now sitting happily at 3.65v on the 3.3 line, and about 5.1v and 12.1v on the other two. This board sucks a lot of power out of each of them, they're set to about 3.9/5.35/12.5 at the molex. But that's not the point, I've managed to damage my Vantec Nexus rheobus somehow. When I was sleeving it, I managed to get the 12v and 5v pins the wrong way round on one molex (just the one, I checked all the others after I found this), and this one happened to be the one that feeds two 12" cathodes, two 80mm fan cathodes, and the rheobus. So when I turned everything on, the cathodes didn't work, and the fanbus was only putting out 5v fixed on each channel (it's meant to vary 7v-12v). Eeeek. So I turned it off, found the problem, and fixed it, but when I plugged everything back in I found that while all my cathodes survive, the fanbus will only put 12v through each channel, no matter what the knobs are set to. It's probably broken, but can anyone give me any ideas as to what I could do to be sure? There's no evidence of anything burned out on the PCB, it just refused to change the voltage when I tell it to. Looks like I'll be in the market for another
Yer, I pulled it out and plugged it into t'other computer, same thing. Had a look on the underside of the PCB and there was some odd orange stuff between the 5v and ground contacts, scraped it off but still no go. I reckon the 5v must be shorted to ground, so changing from using ground as ground (12v) to 5v as ground (supposedly 7v) isn't gonna make a difference. But on the upside, at least I didn't plug the dodgy molex into my hard drives or my Radeon, I'd be a lot more unhappy than now, getting to shop for a new fanbus [/eternal optimism] What I really want is a Vantec Nexus that does 5v-12v and off, for each channel, still with the clean looks. I think the Coolermaster Aerogate I is the closest to that, it looks like I'll be able to get it out of its shell and put it in a Lian-Li blanking panel easily enough, and it goes down to 5v, if not off.
