Screamer Rebuild lin-li75b

I'm re-building screamer with a new (used) Lian-Li 75B Case.

I have finished my 64 bit on a budget. Now it's time to go with this project. 

 

I busted into my credit and got a PNY GeForce 7600GS 

GeForce7600GS PNY

Good Card, works with ¿Vista OK.  I'm also running PCLINUX2007 and it runs pretty slick too. 

I have a growing contempt for ATI GPU's. Every since AMD bought out ATI, the overall quality of drivers, stability and hardware quality has gone down hill.

 

 

 

More or Less Finished 

Lian-Li finished

I'll shit can the Saitek keyboard and my current 9600 ATI card.  No more ATI, I've had enough!

Saitek keyboards don't last long!!

Lian-Li

Inside looks good. I still need to re-wire the UV lights.

Has an odd squeal when It starts. WTF?

Part of the squeal was an alarm on the modular drive racks. The power supply still lets out a little squeal.

Half Ass, almost looks like a computer.

I'll do the custom wiring, when I can concentrate.

Since my head feels "full", I'm sticking to easy stuff today. 

half-ass rear

I like the "finger choppers", rear case fans.

No top fans, just filters.

I have to finish assembling my peltier module.

Add a resister, heat shrink and wire to switch bay.

I have a head cold so I'm moving at the speed of mud.
Pump Stand finished.

Painted with wrinkle black.

Assembled to the pump.

I have some rubber feet for the bottom. As soon as I find where I put them.

This also gave me the clearance need for my peltier add-on for the tank, bottom. 

Drilled, screwed, ready to paint.

Nothing fancy, just something to add height to the pump.  Pumps are rated by height, angle and length of tubing though which it will push fluid.

Ready to drill holes for pump and to assemble plate to tubing.

Always clamp your work

Another test?

temperature test run on water cooled computer

Reads 81.5° Fahrenheit with fluid running for about 30 minutes.  With no fans running, this renders the heat sinks ineffective.

How much does pumping raise the temperature of the fluid, without the processor heat?

Answer is about 8° to 9° F

So thermal energy is transferred from the pump motor, to the fluid.  This is not a lot but every little bit adds up.  With the case completed with fans running, this cool things down a bit.

Here I'm using a Radio Shack Inside/Outside Digital probe.

temperature test run on water cooled computer

Reads 73.0° Fahrenheit with pump off for about 30 minutes.

 My refugee meat thermometer was too in-accurate and hard to read.

People said I was wasting time, placing heat-sinks on the pump.  Well it's not much but computer case-mods are like building race cars, everything counts!

No Bubbles, Running Clean

 no bubbles running clean

I test the setup with NO Hose Clamps and it must pass this test before I apply hose clamps and start adding computer components. 

I moved this to the dining room to finish testing, made supper and watched Myth-Busters and Smash Lab on TV.

No Bubbles

I put some pot scrubbers in the tank  temporarily to take out some weird little white floaters. Made a good filter.  It's clean now and I've removed the scrubbers.

 

Bubbles

Bubbles means a possible air leak or the mix has too much water.  Here the tank was not screwed down all the way.  I discovered this with an air duster. It would chase the fluid around  that is caught in the threads.

Another thing to watch out for is over filling the tank.  Fluids are un-compressible, but still can expand and contract.  Fluids can change volume with ease.   So if you over fill, you can force a leak.

 

Thermo-Electric Cooling 

 

I'm in the process of building the pump stand now.  I'm adding a small 20mm peltier module under the tank for extra cooling power. It's only 3 volt so I'll add a resistor.  I'll hook up all this crap and cover it with heat shrink.  Then I'll hide the wiring inside the pump stand.

This will be controlled with a switch. I'm short some thermal epoxy and I have to finish the pump stand.

This is another old project, resurrected for this re-build. 

Gotta have a rice cooker.

I use 5/8"-3/8" heavy wall tubing with 1/2" fittings.  I've never had a leak with this setup and flow rates are fine.

 

I love water cooling and working on case mods.
120mm radiator, fan & filter installed.

some assembly required radiator in case

I'm short 1 acorn nut and need to cut off the screws. I also need to make a pump stand to raise the pump a bit.

Pumps are rated by how much and how high it will pump fluid so every inch counts. 

120mm square fan filter was the best choice to cover most all of the surface area. 

120mm fan filter to keep radiator clean

I hate dust bunnies in my radiators.

Some Assembly Required. 

some assembly required to make a 120mm sandwich

Odd color but I like a fan with "teeth".

Made specifically for restrictive air-flow like radiators and filters.  Comes with 2 extra tails with resisters but it's very quiet anyway so I'll just wire it up straight.

I used some "all-thread" since there is no way to get a screws head in there.  

120mm fan assembled with all-thread

I used hemostats to hold a nut in position then just turn the all-thread till it takes hold.

All thread is just threaded screw stock with no head.

Full of dust bunnies in the coils and red dye inside. Dishwasher with a couple of drops of regular soap does the trick. 

rinse job on the radiator in the dishwasher

I had some aquarium thermometers stuck on there.  This got it warm enough to remove the adhesive.

I had to disassemble my water block to remove some weird red gel.  There was not a lot but it looked bad.

Here I was just trying to rinse out my system by running the pump. 

rinse out a water cooled computer

I kept adding fresh water, running, repeat. Some vinegar would have helped but I was out. 

Why NOT to use red dye. 

red dye in a water cooled computer.  Don't Do It!!

At least it did not attack the Tygon Tubing.

I've had these CD covers (bezels) around for a long time, just sitting in a box.

lian-li bezel holes drilled and mounted

These required drilling holes for the mounting screws.  I'm trying to use up leftovers on this project too.

 

These match the case. 

lian-li cd/dvd bezel

I'm glad I covered the case in tape. Aluminum dust and shavings just get everywhere.

Here I've drilled 2 holes, and joined them with a small cut from a Dremel tool so I can insert the jig-saw blade.  

lian-li blow hole start  

 It takes guts to whack a hole in a perfectly good and expensive anodized case.

I approach the cut and try get lined up before I hit the line.

 lian-li blowhole start detail

Jig Saws can turn tight but not real tight turns.

Since I live in a duplex, I have to "time" when I use my jig-saw. I had a "Snow Day" so It's whacked now.

Here I got rid those stupid factory grills. 

lian-li back grills

These are nothing air blocking, dust catchers.

I had a "Snow Day" so I started "whacking a Blow Hole".  

lian-li 120mm blow-hole finished cut

I stop before the cut is finished and tape the scrap down so the saw does not take off with the scrap.

I've moved the blow hole back from center to make room for the  mobile racks.  I have to do my jigsaw work when the neighbor is not home since it is loud. 

lian-li 120mm blow hole layout  

 I've started with tape & bubble wrap to protect the parts sticking out from the case.  I'm getting ready for some JIG-SAW work.

lian-li taping jigsaw

I'm cutting out the cheesy factory fan grills. I was going to remove the top, cut the 120mm blow-hole the re-attach it.  I decided against this and will just do my cuts with the top in place.

Next is cutting a 120mm hole in the top of my case for my black ice radiator.  Centered side-to-side, but not quite centered front-to-back.

Black Ice 120mm Radiator

This has been a great radiator. Fan goes on the case 1st, then the radiator.  The hoses will be facing to the window.

120mm fan

Noctua NF-P12 120mm x 25mm Fan - 54.3 CFM at 19 dBA

Made for restrictive air flow situations like radiators and filters.

Gawd what a monster!! 

lian-li

ripped, stripped and waiting for parts.

 It has a factory case window but no blowhole.

lian-li case

I'll cut my own 120mm blow hole for my black ice 120mm radiator.

I know this case is obsolete but I wanted one anyway.

lin-li75b

A perfect case for my old tired Barton Core.

New fans

 

Intakes above, exhaust fans below. 

  Cool looking fan

Wide open finger choppers

I don't want a bunch lighted case fans. I'm keeping the case clean looking.

The 2 fans holes above the power supply is a mystery. These are too far away from any component do do much good.  I will cut out the grills and cover it with something.  Filters? Mesh? More fans?

 

 

I bought some goodies like a pump relay switch and a Apevia 750 watt power supply.

Get the power cord outside and gives you control over the pump.

I'm still busy playing with my budget 64 bit box.

Open Arena runs nice on this.
