|Hardcore chipset cooling #2|
In my last article "The ultimate chipsetcooler" I showed you how to rebuild your Intel boxed cooler to fit the Abit KT7A and possible many other mainboards (using the same technique).
This time I will take it further and use a peltier-element in combination
with the Intel-cooler.
But in order to start using the peltier, I had to make some preparations.
The picture above shows the chipset before treatment.
Here you see the chipset after it has been polished with very fine grit-paper,
this is done in order
The next thing I did, was to make some "anti-slippers" to make sure that the peltier never comes out of position. These can be made of most anything plastic. I made mine with some "rubble" I had laying around. It doesn't matter what you use, as long as it serves it`s purpose!
Superglue the "anti-slippers" to the chipset`s edges...
...and the result should look like this!
The 30x30mm peltier is a perfect fit since the KT133 chipset measures
are the same. The 20x20mm peltier was ordered to support other chipset`s
like the Intel850 with a smaller "core"
The picture above shows the peltier safe in it`s "bay", insuring that everything lays were it should be after the finishing mounting has taken place. Just remember to get the cold side of the peltier downwards, or else your in for a disaster. Apply thermal-paste.
When dealing with low temperatures there is always a risk of condensation,
and to eliminate this
The backside of the mainboard will also be at risk of condensation, so isolation must be added here to.
Before I apply thermal-paste on the top of the peltier, I do one last
check to see if the isolation
After this we apply a thin layer of thermal-paste on both the cooler and peltier, as done bellow...
...place the cooler on top, reverse the board and start tightening the screws.
Picture above show the heatsink before mounting the fan.
The first thing I did after firing up the system, was to check the temperature
of the cooler, it was not so hot that I had feared it may be. The Intel-cooler
is not exactly the biggest heatsink on the market, but it was sufficient
enough for the "peltier on chipset" combo. The good thing about
it is that it`s very silent!
I went in the BIOS again and raised the FSB to160MHz and I/O voltage
to 3,7V, rebooted and the same thing happened, 160MHz FSB and still loading
Windows without crashing afterwards.
But I could still post the BIOS all the way up to 164MHz!
My RAM is made by Mosel Vitelic, it`s not the best SD-RAM on the market,
but is a fairly good for use when overclocking. The chips is rated 7ns,
and most people can push them up to 150MHz [email protected] with a some luck.
But my next question was: what if we also tried cooling the RAM?
So I e-mailed OcShoot for some Artic Silver, and a few days later it arrived! Supplyed our sponsor: 3DfxCool
RAM-cooling solutions can be bought, but I wanted to make my own heatspreaders. So at work I cut some thin copperplates in matching lengths for my Mosel chips.
In order to fasten the heatspreaders I had to use Artic Silver.
After the gluing, I applied some pressure for a hour.
Pictures bellow shows the finished product.
Simple is best!
After some experimenting, I concluded that RAM-cooling does not offer
much speed increase.
But anyway, have fun!
