Ultimate Cooling System
OCGeek writes "This should be interesting for the overclockers as
VR-Zone has an article up on building a
cascade cooling system that
cools chips down to -110C. The guide shows you the components that are required
for the cascade cooling system such as the compressors, condensers,
refrigerants, evaporators, heat exchangers, oil separators etc. and the tools
you would need. It allows hot chip like Prescott to reach over 5.1Ghz and ATi
Radeon 9800 XT card to reach over 660Mhz core."
In a controlled situation, you wouldn't have any problems with condensation. I imagine when they turn the coolers off, they would want to bring the temperature back up to room temperature via a controlled sequence. You will get condensation if you go from that cold to warm rather quickly.

your eye has 2 parts, rods and cones.
cones are the colour receptors (iirc) and do have a "refresh rate" of about 30fps.
rods, on the other hand, are the b&w receptors. the rods "refresh" at closer to 60 fps.
this is why most people can see a flicker with a 60hz monitor but not with 75hz and up. its also why people can see the flicker from flourescent lights.
your eye has a higher density of cones near the center of your vision, but a higher density of rods near the peripheral. this makes your peripheral vision more sensitive to flicker (one of my old bosses cant see 60hz flicker if he is looking at it, but can if he is looking beside it).
honestly i would say that if you could do 75hz refresh on the monitor with a video card capable of doing a consistent 75 fps throughout the game (which currently is not the case) then you would have about as perfect of a look at the game as you can get.
i can see a big difference between 30 fps and 60 fps, but beyond the 60fps i cant hardly tell anything different at all (even with 120hz refresh)
60 feels ALOT smoother than 30 (was tested using a game where keeping 60fps was not an issue given the hardware that was being used) but both are playable.
a bigger issue is probably the fact that on a modern game if you peak at 30 you hit lows of 5, so peaking at 150 would give you a low of higher than 30.
