Systm over at revision 3 has just released a vid tut on this.

Thanks, that was informative, especially on the dangers.. I wasn't really told about these when I learned the process.. I was told: "see that yellow line on the floor? someone used a metal pan, it got etched too and then he ran with the pan outside.. " as a warning that FeCl is a bad thing that stains

About my circuit: I don't have a laser printer, nor transfer paper. I used photoshop to make a smaller version of a print screen of the program I am using (layout plus, not free, almost infringing on the professional side, part of a very complex package of electronics testing and making program. got it from school, and just for educational purposes, so I don't have all features.. e.g. can't make my own components>limited, foot prints and stuff) and mirrored it on paper. After making the paper mask (cut black lines with sharp blade), I used a black marker to trace the circuit... Here is where I f-ed up a bit: I forgot a line or two in the process and also miss-aligned some components. The board is semi-functional as I've lost one of the output stages.. D'Oh! But I did get my led fired up and it is always on, as expected, and I can power one fan, with minor (really minor) speed adjustments. I had to drill the holes, solder the components then redrill some other holes.. I kinda messed up, but one thing did happen: I learned. What? The timing circuit is getting really hot after extended usage and it shouldn't. The utility I used to make the circuit wasn't very precise at estimating heat output, as it was running in a tweaked and skewed mode to allow for the pulses to be correctly interpreted.. usually, a jump from 0V to 12V is seen as a "convergence error" and you have to loosen the precise nature of the math part... So, I am back to the drawing board.. and gonna put more protections and safety measures on the board.. I wish I had an oscilloscope to see if I nailed the signal shape.. My multimeter can't tell me much in that area... So, long rant.. this is more of an electronic forum material, but as it is a fan controller, I will put this in from time to time..

On the side of the real mod: Can anyone help me with the following?
I plan on using a peltier to cool the liquid in my water cooling loop by using a low-flow, low-restriction in-line block mounted on a big chunk of aluminum, running on the side of the case (the back of the pc, behind the mobo), as big as possible.. This will make my PC heavier, but I can leave with that.. I don't plan on giving too much juice to the peltier so as not tho freeze the liquid.. but I was wondering how to calculate the temperature differential that will be created.. I'm gonna dome some 3d mocking later.. (I'm sick as hell right now.. my nose is like a bunch of slugs having a party, if that's possible, and my eyes are like disco balls.. can't even model without messing up.. darn flu..)

I would have: loop=|waterblock|peltier|huge_radiator The water coming out of the cooled waterblock would go straight into the cpu block and then to other components.. Then into the radiators and finally back to the cooled waterblock. Is this a good idea from your experience?

Gonna go eat some hot soup.. bye..

That looks good.
If it's any help this is what my loop will be.
res - pump - cpu - 80mm rad - gpu -120mm rad - res

[dgrmkrp]

That's what I was thinking to do a loop like, with waterblock and radiators alternating, but that way, in my case and arrangement, there would be too many tubes
And I would like the thing to be cool and have the components as visible as possible, so a nice tubing layout is a must.. Plus, I use less money in the process if I use the minimum amount of tubing

[The boy 4rm oz]

This loop suites my case perfectly but for you you will have to do something slightly different. May I suggest the new black coolant that Danger Den sells, it would go perfectly with your mod. My tubing cost me $15 a meter and I bought 3 meters.

[dgrmkrp]

uuu... black coolant? this is the first time I hear about this... Tubing here is less expensive, put it is PVC tubing.. about 2$ per meter, but it is only 10mm.. so are all the fittings.. europe.. Black coolant would be intriguing and nice... especially what I'm planning next.. I think I'm gonna save some money (need about 10 more bucks) and buy myself some new stuff.. Then, some sheet metal! and in the second half of september, when I'll have lots and lots of free time, I'll be doing the N0name a big make over Really big.. Of course, that is not a promise

10ks for the tip, I'll be sure to look into it..

[The boy 4rm oz]

If you have a look on the Danger Den site you will find the coolant fairly easily, I think it looks cool but ended up going for UV Green.

[dgrmkrp]

I found it but it is a bit expensive for a coolant I payed 10 bucks for the uv die (not really.. hihi..) and 10 bucks for the water treatment (anti corrosion+water wetter+anti-algae).. And the bottles I got are concentrated and could do 2L of water.. But there has to be an alternative and they give it to you: food coloring.. They use, so I should find a suitable die myself I'll edit this post later for some pics..

EDIT: like I said, I'm gonna put some nice pics here of why I wanted to post some posts ago.. I don't wanna make this thread a really long list of journal entries.. some too short, so I'm gonna try to reuse the posts more off topic

So, I'm sticking to my plans for this case: as black as possible, black leather outside.. eventually, lots of cooling and should be silent too. After seeing some things I just couldn't say no to and then thinking how I could incorporate them (lol), I got here:

You should be able to spot something strange in the middle of the case: a waterblock attached to nothing.. It is where I plan to mount the peltier so as to have a variable degree of a cooling boost at my touch Straight out of the pump, straight into the cpu block.. Cool water or anti-freezing liquid (depends on how much the peltier can cool)..

..on the other side, disconnected as much as possible from the case, a huge radiator from audio amplifiers, with a slight modification: the fan carved into it.. Fan could run in 5V mode, as I saw with my 400W amp.. cools it just perfectly and the peltier is only 150W It would be interesting to see if there is no need for other fans..

..for the inside cooling.. I "sketched" the 3x120mm holder and guestimatted the area of the side openings is enough for them in 5V mode.

..as for the hard drives.. I would like to keep the visible side of the rack screw-free.. so I'm gonna glue some L shaped parts to help as guides and screw the drives only from the invisible side.. Plus, I like flames and they should continue on inside, matching the side panel and etch..

More to come.. as I plan my next mod-a-thon

[The boy 4rm oz]

I thought about buying the additives and making my own coolant but just ended up buying it purely because I couldn't find any reviews to show if bought or mixed was better. I spent a lot on my coolant $30 per liter (alpha cool) and I bought 2 liters.

this is going to be nice ... but could you do a render without wireframe?... would maybe look better, but nice moddeling :O
looking forward to se how its gonna look with leather on the outside xD

I could do a render, but now it far from that point.. I don't really have the entire case digitized and I could change my mind on what I'm doing anytime..
that's the advantage of not screwing anything in real life I shouldn't have said that, came out wrong I mean I don't have every part which goes in the model.. But maybe I will.. night time fun..

I bought a 100 pack of aluminum rivets and the peltier is in he post.. office, have to wait till next week to pick it up.. jerks.. the customs are open only for 4 hours, one day a week.. and I'll bet they'll charge me with a storing tax.. plus 40% on the 3$ I paid for the product itself.. sheesh.. I need a cheap rivet gun now, and a drill is very important, as I don't see myself making holes in steel with a screwdriver (works on aluminum!)...

I'm gathering funds to either buy a new video adapter (decided I should get a quadro fx, not an 8800 series.. suits me better) or change the loop I have with 1/2" stuff: apogee gt, mcw30, 1/2" tygon, dangerden hi-flow fittings and an OVV block for the peltier.. so I'm have some stuff remaining that I won't use.. lol.. more for the closet


Buying will have to wait after the 13th of September, of course, cause of the exams I have.. Which remind me I should either pick up the dremel, or continue studying electromagnetic fields!
