February 24, 201115 yr Author One of the reasons I opted for a modular psu was so that I could feed each set of 5 molex from a different 12V cable on the PSU so if one cable/connection failed the backplane would not loose power. Not sure if this works in practice, the psu should arrive today. Each Molex powers a different backplane, so if one of your cables "dies" that backplane goes down. I also not sure if you are going to be able to fit 5 seperate braided PSU cables through the hole where the molex need to go. And if you do, theres not alot of space between the fanplate and the backplane for anything to just "sit" in there. But either way, let me know how it goes.

And if you do, theres not alot of space between the fanplate and the backplane for anything to just "sit" in there. But either way, let me know how it goes. I have installed the PSU and I was able to fit 10x Molex through the opening. I am using the Corsair modular PSU and it comes with 3x cables with 4 Molex on each (daisy-chained). I plugged 1 of the cables to the 4 Molex sockets (top down) on the left, a 2nd cable the 4 Molex sockets (top down) on the right, and the 3rd cable plugged in the Molex sockets (left & right) on the 5th (bottom) backplane. I installed the 3x 120mm fan bracket with the replacement fans on the 2nd (further away from backplane) row of pre-drilled holes, this gave me a little more room between the fans and the backplane but its still pretty tight!! The cables/connectors are only about 5mm from the fan. I am running a preclear on 4 Hitachi 2Tb 7200rpm drives. They are running a bit hot though; 38c ~ 44c. The fan replacements are much more quite than the original ones. I know it's not the fans keeping temp high because I was getting similar temp readings with the stock fans. Will keep you posted..
February 25, 201115 yr Author You were stating you were going to use a single cable for each molex. That is why I said it would be a tight fit. As far as the temps, you are using 7200 hard drives and they are going to run alot hotter than the green drives.

As far as the temps, you are using 7200 hard drives and they are going to run alot hotter than the green drives. Sorry, I should have been clearer, I meant a single molex daisey-chain cable per column of molex sockets, that way if one daisey-chain cable fails, hopefully the other daisey-chain cable keeps the backplanes powered as either of the molex connectors on each backplane can power that backplane. As far temps go, I still think they are too high, I have a cooler master case with 2x 4 in 3 drive cage running 6x Hitachi 7200rpm drives. They run mostly in the low 30's even high 20's. I think in trying to keep nosie down I may have under spec'd the 120mm fans. I think I should have got 2000rpm not 1400!! Once the preclear is over I shall try a few things to see if I can get it to run cooler. May be while preclear is running would not be the best time asses drive temps!
February 26, 201115 yr Author May be while preclear is running would not be the best time asses drive temps! I am actually running preclear on my drives as well and 3 of them are at 23 degrees and the forth is at a scorching 24 degrees. lol.
