Hi, I bought a brand new system about 4 or 5 months ago, took me on an Antec P-180-case to keep the noise down a bit. This is where we got our first problems. The top-mounted outtake fan regularly rattles, though a reboot or a good solid hitting the case a few times gets it zooming along quiet-ish again. I still want to replace it, though, because the rattling is horribly annoying. What brand/type of fans are great for silent, reliable outtake while compatible with the case?
Second problem: the PSU. I bought an OCZ 450W Modsteam, thinking the modular design would really work for my system. Oh, how wrong was I. It comes with EMI-shielded cables, which are WAY to fat to fit through the P-180 somewhat decently. I had to remove the bottom compartiment throughput fan etc. just to make it all fit somewhat. So, I want a PSU that will fit in my case while making me take advantage of the whole "shield two compartiments for airflow"-thing. Something extremely reliable (I had a brand new PSU burn through my system once before, so it needs all kinds of safeties built in before I can trust it), with normal cables and an output that powers my system with a bit of room for expansion.
Thirdly, my graphics card. It makes a helluvalot of noise. Are there any silencing-solutions available yet for a factory-oc'ed XFX 7900GT (last time I checked, they were still working on it, but I can't remember what or where)? What are the effects of such a solution on other aspects of the system next to silence? And most importantly, is it doable for somewhat of a layman when it comes to computer building? I mean, I can cram parts in a box, but I've never been anywhere near a soldering iron or the likes.
Bonus problem: AMD Cool'n'Quiet doesn't seem to work on my system (see specs below). I asked Asrock tech support, they said it only works with the stock AMD cooler. Shouldn't it work with any cooler, seeing as how (if I got this right) the motherboard is supposed to simply cut down on fan voltage when clockspeeds cut back? I installed everything you're supposed to install (the AMD driver, BIOS updates and the likes), but it doesn't seem to work. Also, I keep hearing my processor is supposed to idle at 800mhz, while it never goes below 1000mhz, possibly related?
There, that's it. Thanks in advance.
