Cooling your Computer [Projects]


cold 220x220 Cooling your Computer [Projects]Last time I addressed this topic it was to come up with
a few things that can make your computer running smoother. This time I’ve found
a series of projects of the more experimental kind. Keeping your computer clean,
is something anyone can do, but rebuilding (partly or complete) it might be out
of your league. But a fun read still. You’ve probably heard about water cooling
systems, but what about mineral oil, or liquid nitrogen ? I didn’t think so…


I recently came across a picture where someone had built an entire PC-case
out of fans. I have lost that photo, but I imagine you would need quite the
power running all those fans. Not very economical perhaps. The fun part about
all the following projects is that they can actually be performed at home. And
it doesn’t take much know-how to do so either. I post links for further reading
for those interested. Also, Should any of you decide to try one of these
projects, we would LOVE to publish an article about you and that project, here
at Mintywhite.

Water Cooling system

Water Chilled Heat sink

Remove the old Heat sink, replace it with a water chilled one. Add some
tubes, a pump, a radiator, a valve, a fan and a small water tank. Assemble it
all inside your Desktop Cabinet. Boot your computer. Enjoy a slient, cool

Pros: It’s a well-tested system that works well. It is easy to get
all the parts you need, both as loose components but also as a building kit.
Reducing high-load temperatures by as much as 40°C (104°F). Relative
inexpensive, though you should expect between $100-200, depending on your kit of

Cons: Modification of the case is needed. The case also need to be a
large High Tower variant. Water leakage will cause serious problems, so regular
maintenance is a must.

Verdict: Possible

Submerged in Oil

Submerged007 500x375 Cooling your Computer [Projects]Yes, I am not kidding. You take a tub of sorts, remove
the hard drive, and power supply, add about 8 gallons of a liquid, and you
should be good to go. There has been many projects on the subjects with a lots
of different approaches. Many kinds of liquids have been tested, among these are
de-ionized water (caused blackout after about 5 minutes), motor oil, vegetable
oil and synthetic oils. It seems the best results comes from using clear mineral
oil. Oil does not lead electricity while it keeps the components cool. Tests
show components may live longer than normal.

Pros: Total silence. No noise what so ever (except from the hard
drive and power supply, which of course shouldn’t be submerged - even though it
seems that the project shown on the right have succeeded in doing so). The only
rebuild necessary is to remove the CPU fan, and seal the Processor. You can use
any tank you choose, from a tub to an old aquarium. It’s a very cheap and
inexpensive solution.

Cons: Choosing the wrong oil, will cause a distinct odor. If leakage
should occur the results will be about 8 gallons worth of oil running out on
your desk and furniture.

Verdict: Possible

Using Liquid Nitrogen

cpu pipe Cooling your Computer [Projects]This is the ultimate in home-built PC Cooling. Little rebuilding
is necessary, but you do need an open case. Remove the CPU heat sink. detach the
fan, and weld on a copper tube to the heat sink. Insulate the tube with proper
material. Re attach the modified heat sink. Fill it up with liquid Nitrogen and
Boot the computer.

Sounds like utopia ? Well not quite. Back in 2003, a few guys did this
project to be able to squeeze at least 5 GHz from an Intel P4, without causing
system crash or overheating. They achieved to overclock 200 MHz (factory
setting) to the record speed of 5255 MHz. Not very strange as the Liquid
Nitrogen kept the processor and surrounding units at about -190°C (-310°F).

Pros: Extreme overclocking capabilities. Little or no

Cons: Where to get Liquid Nitrogen? It needs constant refueling.
Extreme safety precautions are necessary. Expensive.

Verdict: Don’t try this at home
