Note: First post updated pic of rig with shot of latest front view. Here's a mini version:
Will get a side/quarter view posted ASAP.
I'm finally getting around to doing a little updating, after having my devastating romp with sleeving my PSU. It was a real tragedy -- I sleeved the entire PSU, and was pleased with how it looked. But I could not get my computer to start up. No beep at all. It would just click on very quickly and immediately turn off, and then I couldn't get it to do the same thing unless I unplugged and let the PSU sit for a while. I checked all the connections, and made sure all the pins were seated well. I started to think that maybe I had pulled a connection loose inside the PSU itself. Finally, I decided that it must have been one of the pins on the 24 pin connector, because I had squished a couple of them, not even a lot, but enough that it made me suspicious.
So one at a time, on each wire, I pulled the sleeving and carefully shrinked heat shrink pieces back about 4" down, clamped it, then cut off the connector and the last 2" of wire. I had a pristine connector with fresh clean pins and wires from an extension cable. I cut that off with 2" of wire, and soldered each wire together very carefully, heat shrunk all those solder joints, and plugged everything back in -- of course with the same result!! And at that point I had made a real mess of my careful 8-hour sleeve job.
I unplugged everything except the 24 pin & 8 pin, and what do you know? The PSU powered on, and of course beeped about having no HD or GPU, but still, that was progress! I was sure the same test earlier had failed, but most likely, I hadn't seated the 24 pin properly earlier. So then I attached the modular dual PCIE cable I had sleeved, and it still powered on, and I got the "No HD" post beep. Great! I plugged in the modular SATA power cable that I had so beautifully (or at least, adequately) sleeved weeks earlier. Aha! No boot!! Upon inspection I realized my mistake -- when I was moving the crimp-on connectors, I had flipped them around, and the five wires were then incorrectly joined to the pins of the connector.
I swapped that out with a stock Corsair modular PSU cable, rigged in a molex-SATA adapter for the final drive, and voila, boot success!!!
But I was so depressed about $Q#^$QW# my sleeve job on the 24 pin that I haven't wanted to move forward and fix it. I probably will undertake that in the next few days, though. It was a crushing blow, just when things were going well.
Anyway.... enough of that drama!
The other day I took the plunge and decided to use Permatex "Form A Gasket" sealant to seal any air between the rad/shroud and the shroud/fans. It is a non-permanent, removable sealant, black, and it was pretty easy to apply. I am not sure about my temps, though, because I am running 2 Gentle Typhoon AP-14's at full speed, 1450 RPM, in a pull configuration, pulling cool air in through the top, so it's like
RRRRR < rad
It seems like temps are actually higher than before, when I was not using a shroud. It's hard to tell, though, because I've been folding on both my CPU & GPU since I could boot again, for the Chimpin Challenge. I'll be able to tell better on Monday. I can say, though, that with RX240 and the fans attached directly to the rad, I had the lowest temps ever on my rig: down to 23 deg and a normal operating temp of just 26/27 with a light workload (I run a custom Cool 'N Quiet, so CPU is just @ about 800-1200 ghz when I browse, etc).
I am on the list for 2 of the GT 2150's, though, so since those are high speed, I'll probably switch the setup to Push through the shroud, and we'll see. I would even consider doing Push Pull with all 4, pairing the 2 2150's on the front and back of the lower half of the rad, and then having the 1450's across from each other on the upper half... we'll see. It's fun to adjust and monitor the results.
I had a spare SMD LED strip, but I must have fried it, so instead, I am going to put a string of 6 green LEDs along the back edge of the shroud and it should shine nicely.
I need to update some more, about the fan situation (pos/neg pressure, realized I had a big issue) and some other stuff... but this post is way long enough already!Edited by cyclometric - 5/14/11 at 5:12pm
