I contacted Jab-Tech support and they helped me talk to XSPC to get a replacement pump, it should hopefully get here soon for me to try out and send my old one back in, so crossing fingers that everything works well. I'll post results here, and when satisfied some final pics of my build along with changing my specs
what are your gtx 580 temps with the block? im thinking of getting one for my 580 aswell
well I haven't benchmarked, but after boot up my gpu is at about 24C (room temp is roughly 20C, I think). It only really goes up to about 27C during normal use unless I start gaming. The highest I've seen it after a couple hours of gaming has been 48C, this being with my 3 GT-15s at a still inaudible level, I'm sure I'd get better temps if I cranked the fan controller but I'm very pleased with that kind of performance. When I'm done gaming, the temp drops pretty quickly, but doesn't seem to drop back down past 27C, though I haven't left the pc idle for an extended period of time to see if it'll ever go back to 24C. Highest cpu core I've seen was 55C, overclocked to 3.6 Ghz.
Also remember that I had the RS240 kit, and added a RX120 and each with a GT-15. I'm extremely happy with the build, awesome recommendations when I started this thread.
