A Few Hardware Bits
Zygo writes "Most people seemed to like the hardware bites so here's another edition:
A small HD @ GideonTech, the VapoChill PE @ [H]ard|OCP, a big GPU cooler @ OCAddiction, PSU Relay Timer guide @ Virtual-Hideout, a water cooling kit on OverClocker Café, Heat spreaders on OCIA , and to end a PSU at Exteme Overclocking"

I dunno about the details of VapoChill, but in principle a refrigerator could have its 'hot end' glowing red, thereby increasing heat transfer rate. Remember that the refrigerator only moves the heat around, it doesn't eliminate it. The hot end must be cooled somehow. But unlike the processor, its temperature is not limited by the silicon.
Escher was the first MC and Giger invented the HR department.
Windows 2000 picks up one CPU with HT as two _real_ cpu's, XP/Pro detect it as a CPU with HT.
As such, Win2k needs double the number of cpu licenses (so for a dual processor HT Xeon box, you need the next version of Win2k up, with 4 processor support.)
There are a few cheaper models which don't come with a power adapter, expecting to be powered off the USB bus. The thing is, they report their peak load demand to the system's USB power manager, which is the hard drive spinup wattage. This is higher than most USB power busses can deliver, and the result is a current over limit warning and the inability to use the drive.
The fun comes in, because several of these use nonstandard power jacks (and in at least one case, the model hasn't an external power jack at all). You'll be left modifying the case yourself, trying to find the nonstandard power adapter, or trying to find one of the cheaper USB 2.0 cards without limit protection.
What puzzles me is the way these sites all seem to be 'Extreme Overclocking' or 'Overclocking to the Max'. Where are the sites promising Moderate Overclocking or Careful Now Overclocking or Just A Little Overclocking? This area isn't provided for by current sites. I expect there is a whole mod community competing to get the smallest possible overclock.

My simple way of dealing with case cooling is:
Vantec stealth 80x25 fans. They are cheap as sin,
and really quiet. Also, I don't pull air out of the
case at all, other than what the powersupply fans
do. I push air into the case, and mount filters in
front of all my fans. You can usually fit two fans
in the front of the case pulling air in, and wedge
a 1 dollar air conditioning filter in between the
front fascade and the front of the case. If I need
more cooling, I'll do a side or top fan with an
aluminum mesh screen and trimmed air conditioner
filter over the mesh blowing in as well. If all
the air is blowing into the case, and it's all
filtered, you have a lot less dust. You can get
60mm to 80mm fan adapter kits for your processors
and use the same vantec stealth fans to keep them
cool. Piggy back all this with a thermaltake
silent 360w, remove your rear fan that pulls air
out of the case, and you have very quiet system
that blows air out the back like a hair dryer.
The most important thing any republican needs to know.
