I turned it off, and just played Q3 for around two hours in a hot room with no crashes. I'll try AGPMode "2" to see if it crashes with that as well, but it definitely looks like there are some problems on my ASUS P2B-DS (BX chipset) and 4x AGP. Err, maybe it's not even officially supported, which would explain why it doesn't work properly. :) > > Actually, I'm running the bus at 100 MHz.

Two fans on each CPU and duct-tape around the top of all of the fins to keep air inside the sink until near the bottom rather than having the air mostly go out the sides at the top, like Alpha does (but with metal :)). The duct tape actually made a big difference. To reduce ambient, I cut off the stupid air-blocking grills on the exhaust and inlet fan mounts on the case. Then, I took a bunch of old 80mm fans that had died, ripped out guts, and used double-sided tape and duct tape to stick them together to form a "tunnel" through which air flows. This made it suck air out of the case from right above the CPUs, rather than near the edge of the case. Right out the heat sinks and straight out the back -- nice. All of that and a custom dremmel-cut hard drive mount to put the hard drive near the inlet fan (grill also removed) to keep the HDs cool as well as bring in cool air over the PCI cards. Now if only it were a bit more quiet. :) With this double-walled case, most of the noise still goes out the tunnel at the back. Oh well. :) Not bad for about CDN$120 for the CPUs each many years back. One thing I've found is that instead of using screws to mount case fans, use double-sided mounting tape (I use the 3M/scotch stuff). Sometimes it sticks too well, but the padding reduces vibrations which transfer to the case and thus reduces the noise a lot. Also, removing poorly-made grills built into the case often reduce noise a lot, even though air flow increases. This is because both the grill can makes noise, but even more so, most fans are designed to operate quietly at a minimum airflow and become louder with airflow is restricted. Uh, anyway, this is a bit off-topic now. :) Simon- [ Stormix Technologies Inc. ][ NetNation Communications Inc. ] [ [EMAIL PROTECTED] ][ [EMAIL PROTECTED] ] [ Opinions expressed are not necessarily those of my employers. ] _______________________________________________ Dri-devel mailing list [EMAIL PROTECTED] http://lists.sourceforge.net/lists/listinfo/dri-devel
