Excellent. Very neat... I really like the way it turned out. And with the wooden container its probably very quiet

If I turn off the desk fan, it is nearly silent. There is slight vibration from the pump, but your ear must be within 1ft of the box to barely hear it. The front case fan is 5V and the rear fans are temp controlled by the PSU (Antec Truepower). I'm putting the Caravels on a ceiling fan controller, so overall I suspect that even when I have all three PCs on the loop, it will be less noisy than one typical OEM PC.

It's funny, but the loudest thing in the case is the hard drive. I didn't realize how noisy that bastard was until it got to sing solo, so to speak. I spent a couple of hours wracking my brain trying to figure out why the bugger was making any noise at all until it finally hit me. Go figure.

Just got the ball rolling on a new pump ($150 Gen-X Mak 4 for only $65 shipped, hehe), I have the Caravels on the way, and in a week I'm ordering the block/clamp/case for machine number 2. By December 15th, I should be done with the second phase of my Evil Project.

The Caravels and pump are here. The fans pump air like crazy (do you know how fast a desk can be cleared of paperwork? I do, now ... ), and they are not quiet by no stretch of the imagination. They are like a middle/loud HSF, or a vacuum at about 100 ft. I'm going to set up a fan controller tonight in a non-regulated power strip that should allow me to quiet these mofos down. With how much air they pump, I should be able to slow them significantly (making them virtually silent in the confines of the cooling box) while retaining excellent air flow between the two of them.
The pump might take a little longer before I have real statistics on it since I won't be ordering the second case/block/clamp until tomorrow (it'll be complete by the middle of next week, or faster if Becooling is on the ball). I may set up a dummy second loop with my BIX in place of the second water block tonight if I'm really bored, and string the new pump into it. It'll allow me to see what kind of flow to expect out of the new pump, as well as sound check it. The only thing I dread about that is the risk of miscutting the tubing (I don't want to order any more!!!), and having to drain and purge the system, however easy that may be. Plus, it'll throw off my temp measurements (they'll be completely invalid for this test) since instead of a second block adding about 60W of heat into the system, I'll have a radiator pulling some out. This will give me a chance to check the validity of the much maligned bypass theory, though. By design, the entire loop should now be at about 1" ID except for the individual parallel loops. This pump better not suck. No, wait, I mean, aw, f*ck it.

I have the new pump and fans on it. The fans are tuned to 50% speed, and the second loop (also new) has a BIX to simulate the resistance of a second block. Since there is no air going through it and it is wrapped in four layers of towel, it won't be doing much cooling. I opened the bypass to 30%. Time to do some prime95 and see where the temps take me.

Idle: 34C
Peak: 42C I'm going to try this again later with the water flow optimized further and the fans all the way up. Mwahaha!

Idle: 34C
Peak: 41C That's all, folks. That seems to be my best with everything tuned perfectly. The pump is in horrible condition (EBay unit) so I am returning it to the vendor for a refund and I have a nice shiny new one coming in a week with the other parts. The fans buzz something fierce from the controller, so I'm probably going to pick up a Variac to do the job right. In the meantime I'm going to go back to my old pump and plug my fans directly into the wall. The noise from the fans and pump combined sounds like a circular saw at about 20 ft ... very f*cking loud, and I can't hear myself think over it. I would estimate the sound levels to somewhere in the 70 dB range or higher (I've been in busy woodshops that were quieter). All the parts are now on the way, though, so I'll have much to share next week.

I've finished phase 2. I'll be posting some pictures soon.
The hardest part of that phase was dremeling the damn cartridge off of an old Slot A Athlon 700 ... the bastard wouldn't come loose! So far, there is little to no temperature change, but I'm still normalizing the reservoir temperature for testing purposes and trying to tune the bypass volume. I'll have pictures and data early next week.

man, definitely props on the setup, it looks nice.
one piece of advice tho, with such a nice box, get rid of the duct tape duct tape rules, and is the fixer of all, but get some nice polished hose clamps or soemthing

The duct tape on the hoses protects the hoses from damage from the hose clamps (it is soft silicone) and damage from the entry/exit points from the case (sharp metal edges). The only other duct tape is holding my res manifold down onto my res, and I don't think they make hose clamps that big.

Airspirit:
While reading your article, and your comments about the restrictiveness of the radiator, I noticed that it looks the radiator is gravity fed. Am I correct in this, or do I have inlet/outlet confused in my understanding of Danner pumps? Case "Gravity fed radiator" Have you considered simply adding another inline pump to push the water through the radiator, as opposed to a bigger pump pushing the water up through your PCs, to the cooling tower? Case "me confused" I'm doubting this, since this case would mean that the pump is trying to push water into the res, and then the PCs are gravity fed...and the warm water rises to the top to be fed to the PCs...this must be wrong  Case "me really confused" In this case, I'm simply having difficulty following hoses inside your cooling box, and I'm all messed up. |

This is how it works. The reservoir serves as a gravity trap. What I mean by that is that the weight of the water in the res forces down through the tubing and piping in the cooling chest and primes the pump. Once the pump is turned on, it just needs to pump the slug of air out of the block loops and any excess air out of the radiator, and it is bled. The pump is fed a guaranteed supply from the res, and it pumps directly up to the blocks which drain into the res. The only effort that pump has to make is to pump upwards through the blocks, and suck water through the radiator and the restricted bypass. If the bypass is opened fully, nearly no water is pulled through the radiator. If the bypass is only partially open causing enough restriction to the pumps suction, it will also pull water through the radiator to make up for the slack. The one thing that the pump needs never worry about, though, is its water supply, because even if the bypass is completely closed, water will be forced by gravity through the radiator providing an endless supply for it to pump.
Does that make sense?

actually, they make hose clamps to clamp guages (like a tach) onto steering columns and the like, that might just work. then maybe you can put some padding over the hose so it doesn't get damaged, like some foam.
but still, i like the setup

Duct tape is doing good for me, and I don't mind the look. The benefit is that since it is so thin I can gauge the compression of the hose by the clamp to confirm adequate pressure on the hose.
I may change it in the future, and probably will need to when I start using the bottom port on the res. manifold. Until then, I don't see much of a point. Besides, with the positioning of my desks, it is hard to notice anyway.

It's coming along. Picture that with three of those cases stacked without the printer, but with a firewall/router on top keeping the peace.
Nothing ever gets above 44C. Total sound output is estimated at about 48 dB when the fans are on full (37-38 dB with them on low), but the sound is low toned, making it not nearly as bad as the equivalent in high pitched screamer fans. The coolant is a distilled water and isopropanol mix. There is no smell from this system, even though the cap is not completely sealed (I don't want to teflon tape it ... it gives it a bit of breathability, though it means I will have to replenish the isopropanol occasionally due to slow evaporation).

I don't know... I would have gone with the blower featured here if I was you.
What happened to the quick-disconnect fittings? What's going on with the pump? I thought you were returning it? I think you should try to mount that pump, instead of letting it lie at the bottom loosely. Congratulations on the article, it's top notch! |

I went away from quick disconnects to my current system out of fears of reduced flow. Currently, I just need to dismount the block and it will snake out the back of the case with no hose removal necessary.
The pump is mounted how it is due to size, and due to the fact that I watched it collapse 1" BRAIDED tubing due to extreme suction. I wanted to fit it on the PVC structure nearly directly to prevent this from fuxoring my PCs. It made sense to me. This lack of mounting (free sitting) also allows me to sit it on a bed of padding to reduce vibration, which is significant. The first pump was returned and this one is a brand new unit. A blower would be too loud for my tastes, and still not provide the air flow of these two fans (1100 CFM max between them both). The caravels were $40 for the two of them, which is a deal I couldn't pass up. It also looks badass, which doesn't hurt.
