When a Turbocool just isn't enough...

...well, here's the deal. I have a Turbocool 510, and the air in the back gets pretty warm, even though the case has excellent airfow. (15K hard drives barely get warm, 7.2K's are room temp.) I think I may be putting too much power on it, or I may be overloading one of the wires, as I use Molex splitters like mad. My Chieftec case is filled, and I mean filled. I have:

4x 120GB 7.2K IDE drives on an Adaptec AAA-UDMA
3x 18GB Hitachi (the power pig ones, 36Z15 or some such) and
2x 36GB Maxtor Atlas (new) on an Adaptec 2100S
1x Opteron 142 and
Tyan mobo, 1GB RAM, DVD+/-RW, yadda yadda.

Now, since I have entirely too many drives in this case, is there a way I can get a new molex lead from the PSU? My RAID array on the AAA gets all messed up all the time. Sometimes the drives go "down" on the array, and sometimes they say "unused" when it's a 4-port controller with a 4-drive array. Come on here. Anyway, the whole array is one one splitter after another, and I think that's the problem. Every time I try to rebuild it, the server reboots after a while (I never watched the whole thing, it takes 6-8 hours) and sometimes another drive goes "down" or "unused" like the other one.

The long and short is, how can I solder on more molex connectors? Do I just solder them where the others go into the PCB or should I just use AC adapters and rig me up some more power?
 
Contact PCP&C and ask how much it would cost for them to solder on the connections. It is pretty inexpensive and (i believe) would not violate the warrenty. Also, the power draw from all those HDD's sounds enormous. Have you thought about backing up data onto CD and losing a few HDD's?
 
my 510 has 6 different wire strands (with assorted molex connectors & 2 SATA) how many does yours have?

you have a single optical with those?

your not likely exceeding the amps the supply is capable of
consider that after the drives have spun up they are individually drawing about half an amp each, but require 2A to spinup are you employing a delayed spinup? (idle curiosity, again your not taxing that supply in all likelyhood even if you arent)

it certainly wont hurt to spread the load more, but Im not convinced its the root cause of your problem, I employ splitters myself (on the rig in my sig and in my NAS) and with say upto 4 drives per strand you should be just fine

are you using hotswap caddies?
If so Id say its far more likely the root cause (you should see my error logs)
 
no delayed spinup. I don't think I went over the total amperage (although maybe I'm close) but I think it is too much for the few Molex connectors I'm using. I'll try to switch it up a little and post back. I don't think it has 6 separate leads, but maybe 6 of the large Molex connectors. I haven't really counted, though... No hot swap box, either.
