I'm trying to build a mid-range-ish living room game system because of reasons. I modded a USB hub and notebook DVD drive in to the 5.25" bay for extra-easy gamepad and flash drive plug-ins. It's kind of ugly but it's a nice feel for something that's meant to be console-like.
I have a Cooler Master Elite 120, a 35W Ivy Bridge i3, 240GB SSD and a whole bunch of different graphics cards to try out, ranging from a Radeon 6850, GT650, 6670, (DDR5) Radeon 5570 down to a GT630 of unknown and clearly worst specification. PSU is a 360W Gold-series Seasonic that's never given me any trouble.
I can't do a whole hell of a lot about the CPU without switching to a CULV chip and I'm already using a cooler sized for an i7 rather than the one it came with, but seemingly the moment I bring up a game that touches the 3D hardware - even something ridiculously light for a modern hardware machine like Q3A - I get a crash within perhaps 10 minutes. It's clearly temperature related, but the CPU is usually under 60C when I check the BIOS and the actual enclosure is supposedly designed to support even dual-slot high-end cards.
I had hoped to use my passively cooled 6670 for this rig but even my low-end cards can't stay running inside that box.
Anyone have ideas for further temperature management in an ITX rig?
