After weeks of sitting around in a box, I finally got it installed. For those of you that are running a similar setup, have you noticed that it produces a fan whining noise? At first I thought it was the GTX 780 but that is surprisingly quiet.
Hmm, interesting. When I took apart mine last week just to see how it was put together before installing it, I noticed the fans have 2-leads soldered to the board. The Noctua's are 3-wire, right? Could that be the problem? Were they soldered in correctly?Well, after some minor surgery I got my two Noctura fans installed. But unfortunately they're not spinning. Have no idea why, all the cables seemed to be connected properly.
Not using 4 wire PWM fans, still stuck in the '80s ....Noctuas are indeed 3 wires, but they included an adapter which only has two wires for custom fits. They even include this handy 3M widget that allows you to connect two wires without soldering.
The yellow cable, supposedly for RPM connection, is not connected.
The vast majority of PWM controlled fans are horrible. They generate all kinds of noises at low RPMs. (most commonly ticking)
If you want to sell it, please put it on eBay. I would be the first one to bid for itI bought an FSP Booster X5 last year to power two older GPUs. Between the GPU fans and the Booster fan, it got pretty loud in my office. I measured the sound level at 50-52 dB. When I got a GTX970 to replace the two legacy GPUs, I disconnected the Booster power cord but left it installed in case I ever need it again. These changes made a 12 dB drop in ambient noise level, bringing it down to a whisper-quiet 38 dB.
I don't know what I'll do with the Booster - maybe sell it on eBay?
