Well I am super happy with the Velocitor build so far. I have 4 200mm fans coming from Antec...planning to make a push pull rad box for ICE...but that's another thread LOL.
But I thought I would go ahead and fix the broken fan in V and maybe make a shroud from a part of the side panel of a V600 Lian Li I am hacking to bits...it might make the case look bad to build up the protruberance any further...but a push pull on that PA160 would basically guarantee optimal exchange and then I could work on lowering the fan noise from all other areas.
I did put a controller on the top 7800gt fan--the reason it is so noisy is because the slots on the DFI are so close together. In reality the fan would be hiting the knurled thumbscrew on the back of the Zalmanated 7800gt below it--but I made a little spacer from a screw and some nylon tubing and gave the fan blade about a 1/16" clearance...LOL So there is that nasty nattering cavitation noise to deal with. the lower 7800gt sounds completely innocuous. The side panel fan is aimed right over the top card so oddly enough the two card run at exactly the same temps at idel and load...LOL--meant to be I guess. So having eliminated that noise I was still annoyed by a mystery fan--after pressing my ear hear and there on the case I finally found the culprit...
Turns out that the #1 noise factor is now the PC Power & Cooling TurboCool510 SLI. PC Power got famous not just for making a stout PSU--but for having one of the first PSUs with a wicked loud and powerful 80mm fan that helped cool the case.
Back in the day most cases were coming with 80mm fans due to the FF and the the wierd locations of the CPU (slots even). Also most cases were midtowers and had terrible ventilation. So a powerful fan on the PSU was like WOW.
Nowadays the PSU really just needs to cool itself and be quiet about that!
So the TurboCool is pretty much a throwback--although it still pumps out a decent rail. However it is driving me batty listening to the rush of hot air from the 510 so I will soon be refitting it with a Silverstone 560 I pulled from Crunch. The 560 bests the PC Power is stability on the rails too. Although I do not have a scope to look at the noise signatures judgng from the stability of my OverClocks with the 560 and the ability to run 24/7 for several months at maximum output (calculated online according to the components) I have complete faith in Silverstone PSUs. And the Silverstone is dead quiet.
So it is a bother--but in the long run will make Velocitor much better house broken. After losing a couple of rigs to the intense humidity this fall I am loathe to place any favorites out on the porch ATM. Only naughty, lazy rigs get the Porch...excepting Crunch. Crunch is built for the great outdoors.
I thought I would post some screenies here and show you what Velocitor can do so far.
Still learning how to OC a pair of Gts...
The first one is where I am at right now prepping for more benches. I am Folding on both cores while benching--it makes no real impact on the score. I also ran two instances of SP2004 overnight and ran them again just now while folding--they stopped after about 20 minutes. Best so far is listed in the Fmark screenie....
