Finished my H20 cooling project on Enlight 7237!

[ColdMiser]

Here's the deal:
I have an Enlight 7237. Asus A7V. T-Bird 900. 2 x Crucial PC133 256. GeForce2 MX200, SB Live Value, Plextor 16X burner, Zip250 Internal, WD 20GB 7200rpm, 300W PSU

Original cooling setup:
1 80mm intake, bottom front, punched metal fan guard.
1 80mm output, high rear, punched metal fan guard.
1 80mm output power supply, punched metal fan guard.
1 60mm Black label Delta on FOP-38.

The prob: Too loud, only mediocre cooling. Usually leveled around 115 deg F. The tower sits inside a tower cabinet in my desk, which does damper airflow.

The goal: Increase cooling to respectable levels, reduce noise significantly. Must still fit in desk cabinet. Solution must fit entirely within computer case for portability.

Method: Watercooling.

new quarter angle shot. Yes, it all runs with all covers on!

[eh?]

not bad! i did the same thing only i put my 120 on top

Da guts:
Eheim 1048
Swiftech MCW462
Blackice Extreme Rad
Homemade copper shrouds
2 Panaflo H1A 120mm fans in push-pull config
Round IDE cables
1/2" ID silicon tubing
Air bubble trap at top. Closed loop system. Distilled water with Water Wetter.

The final results are that the system runs about 20 deg F cooler, and much quieter. I am very pleased.

Any questions?

Awesome system you built there..I love the Swiftech block for its level of quality. That black ice radiaor performs well from what i hear to.

Nice work. with those push-pull 120s you should replace that 80mm exhaust fan with a 92x32mm Sanyo Denki. I have an en7237 and you can successfully nibble out the 80mm back opening to accomodate a 92mm. Just my opinion.

I hear ya Hoot. It's on the list. Believe it or not, I actually found a way to wedge a 120 back there. After I successfully install my *new rheo* and slow down the rad fans, I can use a nice quiet 120 for the rear exhaust. Replacing the PSU fan is more of a hassle b/c of the way it is wired to the guts of the PSU.

Very nice system. How'd you get the fan shrouds for the 120s? I'd like to have a couple for my next cooling efficiency mod.

dont even bother , i had to replace the hardwired fan in my psu twice, i got eletrocuted - outch

If you got zapped then you didn't let the capacitors drain ong enough. Have more patience. I've messed with PSs a lot and never gotten zapped. Switched fans, installed relays, wiring, etc.

I made the fan shrouds for the 120's myself out of copper sheeting. I will draw up a template of the shapes I cut and post them this evening hopefully. I have to go to a class in a few mins. Both shrouds wound up being identical. The tricky part of the whole thing was attaching each shroud to the rad and fan using an internal attachment method. I didn't want any bolt heads sticking out. They are all hidden inside the shroud. The geometry of it all drove crazy for a while, but I insisted on having a very sleek finished look.

I did a lot of bech testing with the fan/shroud/rad/shroud/fan sandwich for noise. I found that standing the fan off from the rad and shrouding it made a radical diff in noise. At the moment the 2 120's are at 12 Volts, and are almost quiet enough for my taste. And I'm pretty touchy about the noise. I'll get that rheo in the act this weekend probably, if I'm not too busy celebrating my birthday on Friday.

Each shroud is 3/4" thick. The rad core is about 1/4" depth from rad cover, so total fan standoff is about 1" on both sides.
