its a Qpack of course. most specs are in my sig.
the ram sinks on my video card came with one of these, which is cooling my northbridge after some filing to fit around some capacitors. I also put a little fan on the southbridge heatsink.
those titan ramsinks alumimum, but twice as large as the ones that come with a zalman cooler. and the glue is excellent.
I'm using this LG burner
and this powersupply (I've had it for like 6 months, its been excellent) it has a giant 135mm fan on the bottom of it that exhausts hot air out the back.
everything is thermalpasted with arctic silver ceramique.
video card idles at 33 and loads at 57 max. that's down from 39 and 67 with the stock cooler and in my coolermaster centurion mid tower with the fan at 89% speed (VERY LOUD).
the ceramique isn't set in yet.
