Introducing VapoChill !

VapoChill Condensation Problems ?
As one of the first sites we reviewed "slot" VapoChill more than a year ago and we
achieved some pretty amazing results with the 0.25 micron "Mendocino" core
Celerons in VapoChill.
The climax - and the highest overclock we ever have done was with a Celeron 366A which we
managed to take all the way to 760Mhz -100% stable - which is a overclock of more than
100%. All the 0,25 micron Celeron results are here.
VapoChill at that time did not have any electronic device
to halt the power up of the mainboard - they used a dos program to halt the boot
This way of halting the boot is not good enough when you "overbuss" processors
as much as we did - the result was that we ended up with two powersupplies : one dedicated
for the compressor so we could start it and let it run for a while before we started the
If we didn't do it like this the system would lock up at once and we could risk to fry the
processor since we on some of the Celerons used a corevoltage of 2,9Volt. Default VCore
for 0.25 Celerons is 2,0Volt and upping it up nearly a volt more than it is designed for
without some serious cooling is kinda risky !
So I sent a mail to André S Eriksen which is the inventor
of VapoChill and suggested he did halt the power to the mainboard. This mail was the
beginning of a endless stream of mails with exchange of ideas and toughts.
The biggest drawback I found with the "slot" VapoChill was the cabinet which wasn't
especially fancy and it also had only two 5,25" drive bays.
Asetek did at that time deliver the barebone system with a 235Watt powersupply which was
too small - we changed it too a 300Watt and some strange reboots we had disappeared.
And at last Asetek hadn't polished the evaporator - it was milled and was pretty coarse.
Another problem with subzero cooling is to find a heatsink
compound which don't freeze and maintains good heattransfer at low temperatures.
We have tried a lot of them and most of them did freeze and pushed the CPU core away from
the evaporator. This again caused the heat transfer from the CPU to the evaporator to be
inadequate since ice is a lousy heatconductor.
Some compounds we have tested did freeze before -20'C ,one of them were even
"guaranteed" to -50'C.....
VapoChill is now delivered with one of the best compounds we have tested.
New Generation VapoChill:
This is how Asetek themselves present socket VapoChill :
·A progressive and daring design of the
new front bezel provides a monumental enclosure for the proprietary VapoChill technology.
·Original placement and visual presentation of the LED display shows
·LED display transparent cover available in various colors.
·Strengthened metal clips for mounting now allows for continuous
disassembly and rebuilds, and decreasing shipping damages to the front bezel.
·Internal steel parts are powder painted (black) to boost visual appeal
and eliminate all sharp corners and edges.
·Improved airflow in top section including custom cutout for the new
·Separate metal enclosure for cooling unit, designed for improved
airflow and heat release. With this improvement, the cooling unit is effectively separated
from other computer components. This means that apart from facilitating CPU performance
enhancement alone, the heat from the CPU is completely removed from the overall computer
·Extra 5 1/4" drive bay - now total of three.
·Reset switch has been added to the case.
·Extra Ø120mm fan hole placed at the bottom of the case.
Integrated LED display and
·The integration of the ChillControl with a LED display has given the
end user a constant visual confirmation of the functionality of the VapoChill by showing
evaporator temperature. Additionally, the LED display signals limits for boot and shut
·For end user customization and system fine-tuning the LED display /
ChillControl gives easy access for programming of temperature limits and hysteresis.
Socket type CPU kit
·Evaporator, casing and retention clip
for the standard Intel S370 and the AMD Socket A CPU systems.
·Reduced in outside dimensions the patented evaporator technology is
capable of removing even more heat than our earlier design at the same evaporator
temperatures: -20 to -10 degrees Celsius, depending on CPU.
·The overall CPU kit is preassembled for easy installation - No harder
to install than an ordinary heat sink solution.
·When mounted the design of the new CPU kit ensures a 100% even and
permanent pressure of the evaporator on the CPU.
·The evaporator enclosure is metalized to effectively reduce
·Heat sink compound, the high efficiency thermal paste, which is now
part of the standard VapoChill Socket package, provides for maximum thermal acceleration
and correct assembly of the CPU-kit.
·A larger condensing area and more
tubing, yet reduced outside dimensions has allowed for better structural design, improved
efficiency and enhanced slack capacity of the condenser.
·New pipe structure has eliminated the formation of moist and
condensation build-up on the compressor outlet in situations of non-stop (24 hour) uptime.
·The compressor's electrical unit is wired to accommodate variable
(compressor) speed control. This means that it is possible to adjust cooling performance
according to heat dissipation of the CPU. The speed control is based on resistance
·Enclosure of insulation tube with shrink hose to avoid tearing and to
increase capacity has been added to the new generation VapoChill.
