good day everyone! i've finally decided to take the plunge into watercooling. but not any watercooling, thats too easy. you guys and your fancy ass fuzion blocks....HAH! i'm building my own! i'm just that crazy i guess.

actually theres several very good reasons for doing this. going water anyways.

- i've got a heat problem. take a look at the pic of my rig below. its a small cramped case but for some crazy reason i've grown quite attached to it since it was once a beige POS. those two video cards are 7900 GTO's which although nothing too powerful anymore they tend to dump a lot of heat on the heatpipe on the mainboard. thats an asus A8N32-SLI btw. that heats up both the south and northbridges. i get the odd random restart if i dont keep the cover off, its quite sad.

- i want to push my opteron 165 beyond 2.4Ghz. it gets warm, but does it very very undervolted so i'd like to think this thing has the potential to hit at least 2.8Ghz on water.

- i'm sick of the fucking noise!! DIE FANS!!!

- i'm batshit crazy and getting bored so new project time.

now onto the pics!!

mmm theres daemon in that mess of my desk. i gotta clean up.

so here's the inside of the case. i'm quite happy with the cabling job i've done. the layout of this watercooling is going to be the tricky part. the pump is going to go where the lower 120mm fan is....only place for it. theres a 80mm howler fan behind that in the white plastic cover, what a piece of crap. its going to be removed and the 80mm is going in its place somehow with some fun modification. a 120mm will just barely fit where there is a 80mm right behind the cpu if i knock a few more holes into the case.

theres going to be a res in the drive bay and the rad is a problem....its actually going to be mounted on top of the case since this case is just too small for it internally or even for a radbox.

ohhh look at my titties...

now heres all my fun stuff! in no particular order heres what i got: swiftech 320 rad, swiftech MCP665 pump, DD drive bay reservoir, masterkleer tubing (great stuff, fuck the hardware store vynal crap), a 1/2" x 2" x 6" bar of copper and a piece of acrylic thats bigger (forget sizes), some random nylon fittings from a hardware store. barbs are for 1/2" tubing and they're 1/4" NPT. theres some PT nuke in there (just going to run distilled water), swiftech copper ramsinks for the 7900's and there is also a TT flow indicator somewhere....couldnt find it. that grey plate is a S939 backplate for my cpu block:)

at this point i wanted to say a big thank you to you guys on the [H] FS/FT forum that hooked me up with a bunch of this crap! i know a couple of you were curious what i was cooking up, well it begins this weekend. that pump i got off ebay and the guy tried to screw me - impeller was trashed. a kind [H] member sold me a good one from his dead pump:) absolute lifesaver! the reservoir, fittings for the rad (because i'm forgetful and didnt order with the rad), flow indicator and the backplate all came from [H] members and you were all great help and just awesome for selling.

ok now onto the more fun details. how am i going to make the blocks....well they're all going to be roughly 2" x 2" and they're going to be made with nothing but a dremel. check this out:

a bunch of 1/8" blind holes connected using a fine grinding bit with the dremel. the acrylic goes on top and is sealed with about 6 #8 screws and some RTV silicone gasket maker crap i use on my car. pretty simple, but i'm not going to stellar performance here. i think it should do well, my goals are high flow and surface area in this design. do note that i will do some fine tuning that i'm too lazy to model in the CAD. thats solidworks 2008 in case anyone is curious;)

i got the rest modeled but i'm lazy - did i mention that yet? - so no pic yet. maybe tomorrow. got some ideas for the mounting hardware too. this will all start to fit together better once i start building this and taking pics, its kinda hard to explain as of yet but the work has begun:)

oh and one feature that i'm going to put into this WC loop - i hope. i want to have a quick disconnect as a drain valve. keep a male one in the case on a T and then connect the female with a hose on it that goes into a bucket. simple quick and easy drain without any mess.
 
is that something similar to a #Rotor waterblock?


it looks awesome!
 
actually yes rayman the #rotor block was some inspiration for this:) thanks for the vote of confidance.

there are improvements however, i'm using a 1/8" drill to allow more pillars (surface area) and note the small area i've cut out of the top of the block where the pillars are - similar to 'bowing' a waterblock as what is done with the apogee gtx i believe. the idea is to allow a small amount of room for freeflow which greatly increases flowrate. right now its about noon and i've had a yummy breakfast of bacon and a big everything omlette and just finished my second cup of coffee. ready to rock! i'm just going to use a simple plan view plotted on my printer as a template. a lot of this is going to be done on the fly as its just not worth my time to model all the finer details. here's that drawing:

this is the whole thing together - screw shown is a #10 before i decided to go down to a #8 screw, so excuse the large screw there. and theres only one, why bother modeling all the screws and the barbs if i don't have to?

i also just adjusted the hole sizes in the top to match my fasteners, its going to be little bitty #6-32 machine screws holding down the block because thats whats in the backplate. i've got some springs and plastic cup washers to hold the springs in place as well and a couple lockwashers. should provide some nice clamping. i wanted socket heads, but home depot fastener selection sucks and i didnt want to go to canadian tire.

and in case anyone is wondering yes i do mecahnical design for a living;)
