So, once again I'm just sittin' here, drinkin' warm soda. Once every few
hours I head into the kitchen to throw my hot soda down the drain and refill my
cup with cold soda. What a waste. I'm thinkin to myself, I could build my
computer inside a fridge! Nah, who wants to deal with the condensation. I find it hard to justify buying a fridge just to cut apart for my
machine (not to mention how my wife would feel about it!). There has to be a way to keep my soda
I could use a peltier! Check this out.
I started to get my stuff together...
- One cheap waterblock ( I recommend the tidal pool aluminum universal,
available at www.2cooltek.com)
- 2 pieces 3" diam. dryer duct
- 1 3x5 tie plate ( simpson strong tie #TP35 )
- foil tape
- 4 inches of 3 1/2 inch diameter abs pipe
- tin snips or something to cut metal
- 72 WATT TEC ( Peltier )
- cheap 5 dollar copper cold plate
I didn't have a clue how a peltier worked. I knew they got
very cold. That was it. Thankfully I was referred to an expert on water cooling
and TEC devices, Tom R. over at www.ocmojo.com.
He patiently answered hundreds of questions, many of which must have seemed
insane at the time. Many thanks dude!
My first big mistake was trying to convert an old
heatsink to a waterblock. It actually worked okay, until it got dropped and then
no matter what I did it was a leaker. I would suggest you just buy one. It
makes the whole thing much easier and not that much more expensive.
The first thing I wanted to do was get the cup holder
assembly put together while everything was fresh in my mind. I headed to home
depot and browsed for a while to see what my options were. This is what I came
Above you can see Dryer Duct's and Foil Tape and Tie Plate.
The first step is to pop, drill or cut out the rivets holding one of the
pieces of dryer duct together, like so.
Slide the piece that you just cut inside the second piece
of duct. Decide how tall you want the can holder to be and tape the duct pieces
together. Now for the base. You'll need to cut the the tie plate to the
approximate size of the can holder. Then make 2 notches to use to connect the
waterblock hold down ends. Here's how my first one looked. I made another
"cleaner" base after this but this one worked fine and should
give you a general idea of what I made.
Tape the tie plate (aluminum tape is STRONG!, don't
substitute with another kind of tape!) to the bottom of the can holder. Use
narrow strips of tape, this makes it stronger. Place your waterblock hold down
in place and use some pliers to bend the ends through the holes in the hold
down. (note: don't put any tape on the base of the can holder on the inside, the
stuff makes a great heat and cold shield)
Now we can add some thermal compound. Go ahead put the
water block, coldplate and peltier into place and tighten everything down.
Now slide the whole thing into the ABS pipe. Sand down
the edges, rounding them a little and VOIS LA! Sweet eh?
One thing that became painfully obvious as I got ready
to put this in my case was the lack of space. After all the work I had put into
making my old case work no matter what there was just no way to squeeze all the
parts I needed into a mid case. So I went to Compucare and whined at Brian who
was nice enough to give me a deal on a demo supercase. This thing should have
room enough for everything.
Now I cut my hole. I traced the contraption onto the top of the case
and then cut. I wish I had been paying more attention. After I cut
the hole I lifted my jigsaw to examine my handy work and found a nice 4 inch
long gouge in the top of my case. BUMMER. Oh well, to prevent this tape down
some thick paper that the jigsaw table can rest on.
I then took the can holder, found the height I wanted the
assembly to protrude above the top of the case and used a book to hold the top
of the case in place while I did the tape trick once again.
Now that it is where it's supposed to be lets take a look at some temps. First I used
tap water, not very cold either. ( Shown Below )
I put the temp probe in the can holder after about 10
minutes and got the reading below.
Then I waited like an hour, maybe an hour and a half
and tried again ( after putting it into the cooler ).
And then in the can holder again
Then I put it all back together
WOOHOO! I would definitely say that was a success. And there it is. What? You
say you have no water cooling system and they're kinda spendy? Well it
just so happens that I didn't have one either. Ill show you how I put one
together on the cheap.
UPDATE! After I was done with everything I went back to
the way I run my machine normally and for the heck of it tried to get a temp one
last time. Here you see me holding the temp probe down on the base of the can
holder with a thermometer. How's that for a temp?!
