I am currently running an AMD2500+ OC'd to 2.1Ghz cooled by a Thermaltake Extreme12+. The MOBO resides in an Antec SLK3700AMB (Solution Series Mid Tower) I have 2 case fans to bring air in and out, but I think I may be blocking some airflow to the PSU. The case runs really hot right now its at 41 C idle, which (when I asked some people) is still ok, but I would be more comfortable if it ran cooler, then I could turn down my fan (which sounds like a freaking airplane) and enjoy multimedia a little more. I know my setup is generating a lot of heat cuz I am running an ATI Radeon9800 pro, along with almost all of my PCI slots full (Leadtek TV Tuner Card, Wireless NIC, Audigy2, System Status Monitor Cables (Comes with k7n2delta). I am contemplating cutting holes in to add a side fan to take out heat, but I don't want to do anything to hasty... My friend was telling me to cut off the grill on the back, as it sticks out a little, so I am thinking about that, and I tried a little cablefolding and organizing, which makes the case neater, but where I situated the mass of cables makes it a little hotter. Does anyone else have this case, and would be able to help me out a little? I have worked on this setup quite a bit and it is really nice, but the heat (and noise to regulate it) are getting to be quite troublesome.
