Some might call this cheating but hey it works great, cost me nothing and allowed me to use my stock heat sink and fan and reach well below -1c with no mods to my any of my part of my system.
My personal experience is that cooling is everything. And I don’t mean dropping your system down from 35c to 25c I mean getting really cool!
My pIII 700e hit 933 right out of the box with factory settings for the 933 and stock fan and heat sink. And it was running at 39c. I thought hey this was way to easy I'll go for 1gig. I managed to boot up into windows a few times at 1 gig but always with reg errors. I figured I had to cool things off a bit more. If it would hit 933 at 39c it would probably hit 1 gig at 25c. I cooled it down to 25, got errors 20c got errors, 15c and I was still getting errors. I thought if Im still getting errors it must be one of my other cards or the ram.
I swapped everything out and tried again. Still I got errors. Then I got really aggressive with the cooling. I dropped it down to -1c. Presto running rock stable at 1001mhz under all conditions with all my hardware and cards installed.
So here's the big picture. From 700 - 933 was no problem even with the stock fan. But to go that extra 70 mhz required me to cool the chip by 40c.

Ok I hear the sirens from the physics police approaching fast so I had better show you what I did.
Here's a picture of my computer room.

Notice the big bay doors behind the desk. Well I live in Canada and it gets well below freezing for at lest 6 months out of the year. In addition where Im from the air is very dry so little to no humidity.
Now have a close look at this next picture.

notice somthing missing?<Like the case
> Notice a small crack in the doors and wires leading out the doors. Notice an outline of a computer case on the opposite side of the glass.
Thats my chill box. On the night I hit 1001mhz it was -13c outside.
So the question is how practicle is this? Well as I mentioned before Its below zero for more than half the year, there is very little moister and best of all no mods to the system. its a double pane door so the crack lets in a bit of cold air but its nothing this Canadian girl can't handle. Now you dont want to leave your system sitting outside for weeks on end without checking it. But for testing your system to see how it will preform under such circumstances this is great.
I did it becuase I wanted to build a self contained cooling case and wanted to test how my complete system would react to the extream cold. The CD Roms were sluggish but everything else seemed fine. The positionioning of the case directly outside the window also gives me the option of relocating the drives inside with a couple of 24" ide cables.
Oh I should also mention that the overall cooling effect allowed me to use my cheap ram $75 Canadian for 128mb<apacer generic set at turbo and cas 2> and ati rage 128 expert video card.
