Hmm. I'm considering swapping out my Bonneville core (5.5x11x2" finned) for one of these transcoolers to quiet things down a bit.
I'm currently running 25mm delta WFB1212M fans at 7v....less than optimal flow for this thick core.

One option is the mid size transcooler with 7.3" finned width (the one that JW linked above), which I would have to modify to fit the front of my case....it has 16% more frontal area than my 2" thick heater core.

The other option is the transcooler one size down ( 5" finned width) which is 25% less frontal area than my core.

No doubt the deltas will pull more air through the 3/4" transcooler, even at 7v, and hopefully quieter too.

The Sunon 2123xst 120x38mm fans that ferdb talks about here: http://forums.procooling.com/vbb/showthread.php?t=10790 are probably both stronger and quieter than my deltas.

Any thoughts? The thick heater core would obviously benefit from the 38mm fans. Would the smaller transcooler /38mm fan combo work at least as well as my current setup, or is the bigger one worth the extra trouble to modify and mount?

Ruiner · 12-05-2004, 12:42 PM

I'm a doofus. The BIP line of cores is 3/4" thick...the 'plenums' make it 1" thick. And it has 1/2" barbs and copper construction.
That trans cooler does have more surface area of course....

The tranny coolers do sort of have diminishing returns... You can get large ones but getting fans shrouded/mounted and the right amount of fans seems to be a pain. Not to mention the barbs are tiny.

Id like to see pics of what Fokker ended up with though

JWFokker · 12-06-2004, 10:23 PM

This damn 'Christmas season' nonsense has put a serious hurt on my watercooling funds. I still haven't gotten that copper 16" x 16" Honda Civic radiator I want. And I'm quite tempted to get that new Swiftech pump if it's really as quiet as it's supposed to be. I'm a bit confused on it though. It's got 13' head, but the D4 usually outperforms it by a significant margin. I'll have to dig around for a graph of the Storm block's head loss and see where it stands. It is a fairly restrictive block so it should probably be a bit better suited to the G4 than the less restrictive MCW6000.

Crap, I don't know what I'm going to do. I think I'll compensate by taking my MCW50 out of the loop and maybe I'll buy a small Eheim and run it in it's own loop so as not to decrease flow in the main loop or dump heat into it either. I like my Mag 3, but it is a tad noisy to sleep near.

Ruiner · 12-07-2004, 07:19 AM

The pressure drop of the mcw50 is pretty low. Do you think it deserves its own loop?

JWFokker · 12-07-2004, 10:02 PM

But combine pressure drop, added heat and extra tubing and I think it'll make a measurable difference in CPU temps. And it's a pain in the ass whenever I want to take out my video card. A small loop with a 120mm heatercore in a Radbox will probably be the order of the day when I get a DDC and Civic radiator.

You can get Yate Loon 120mm fans that are almost identical to the Nexus 120mm for $7 from isellsurplus.com . Several people on SPCR, myself included, ordered these, and we all found that they are identical to the Nexus fan, except that they spin 350 RPMs faster at 12V. It's an extremely good deal, especially if you need several of them as there is a volume discount. It's argueably the best 120mm fan currently available, and is definitely the best for the price.

DrCR · 01-26-2005, 04:24 PM

Again, agruably the best source for "is this fan quiet, what about this one?...." is Silent PC Review (SPCR), in particular, the Fans and Control subforum there. This sticky thread was created in an attempt to summarize the discussion of this subforum.

The Top SPCR Quiet 120mm Axial Fans Compared + 120mmAC Fans

As a side note, even though I'm the one who started the thread and compiled the information, the real credit goes to the guys trying all these fans out and posting about them. I've got to be careful mentioning names as there are so many who have contributed, many of whom I have forgotten, but ferdb, teejay, pdf27 are some of the many. A big thanks to all who have helped.

I upgraded to a BIP2 and a pair of those sunon 2123 fans. I am very happy with the noise/cooling ratio.

eander315 · 02-04-2005, 10:15 AM

I just received my Derale transmission cooler. I got the 11.75x11x.75 inch model. 4 120mm fans fit perfectly, and it looks like it's not very restrictive to airflow. The barbs are 3/8 inch, but they appear to be smaller ID than the rest of the 3/8 fittings in my system. I may try modifying it in the future with 1/2 inch fittings, as the end-pipes running down both sides are much larger than the 3/8 fittings, and should accept larger ones without problems should I ever decide to bother with it. Overall, it's very well-made, with a much more finished appearance than any of the heatercores I've seen. Mine is painted black with a thin coat of paint. It was $40 plus shipping at Transmission Parts USA .

Nice keep us updated. Is that all aluminum?

JWFokker · 02-04-2005, 02:27 PM

Nice. That's the one I should have got. I got the model that's a couple inches narrower because I didn't realize they measured the entire cooler, not just the finned area. At $40 I might pick it up anyway.

eander315 · 02-04-2005, 04:34 PM

Yeah, it's all aluminum. I'm going to build an external box to house it and the 4 low-speed Yate Loon 120mm fans (the orange ones). I'll take pictures soon and post them here for anyone interested. If I ever get around to buying a new pump, I'll test it for flow reduction as well, just for grins. I was going to use an Eheim 1048, but after lgetting a closer look at the barbs on this thing, I might go with a 1250 instead. I would use a Laing DDC, but I'm trying to keep it as close to silent as possible, and a couple of people at SPCR have said that the DDC pump is too loud to use for near-silent PCs without some work.

eander315 · 02-04-2005, 08:10 PM

Here are some pictures I took this morning. The orange fans are 120mm Yate Loons (25mm tall). The second picture is an attempt to show how much less restrictive the fins are compared to a regular heater core.

I will post more later once I've built the enclosure, but you get the idea.

JWFokker · 02-05-2005, 10:27 PM

Looks awesome. I'm going to have to get some of those. I never run my Sanyo Denki's higher than 5V anymore, so I might as well downgrade to something a little quieter to go with my new MCP350 that should be arriving shortly.

So are you going to integrate a fan controller into the box you're making?

eander315 · 02-06-2005, 03:32 PM

I haven't really deceided entirely yet, but I think I'll probably run a power line from the case to the radiator box, then split it 4 ways to power each fan. I'm going to try the fans at first with full 12V to see how loud it is (they only spin at about 1300 RPM at 12V). If they are too noisy, which will probably be the case, I'll add a 1W Zener diode on the 12V line on each of the fans to drop their voltage to 7V. Those fans have been reported to be completely silent at that voltage, though they don't move much air. I'm probablt going to try to figure out a way to integrate a pump enclosure in the radiator box as well to make things a little neater, quieter, and more compact. I haven't really decided on which pump to use, though I think an Eheim 1048 will do the job, and I can always add another one inline if I switch componentas and need more head/flow. I would use a Laing DDC, but I hear those are not quiet enough for my application.

How do most people integrate power for multiple fans into their radiator box? I've considered using a small independent power supplywith a fan controller, or just running power from the PC to a fan controller. I think the diodes are better though, as they're cheaper, and I don't think I'll ever change the fan speed once it's set to a quiet level.

JamesAvery22 · 02-07-2005, 01:30 PM

Used a 12v brick from radioshack in series with a pot. Originally it was going to be used for powering 2 80mm fans. Think the max amperage it could put out was like 1A. Course thats passive now so all that thing is doing is powering an LED in the power switch

Im sure you could find a 5v brick that can give 1-2As just as easily. Just put them on 5v from a PSU and make sure they move enough air.

eander315 · 02-07-2005, 01:43 PM

I did consider using a small brick like that, among other hare-brained ideas like installing a small power supply in the rad box

I've finally decided on using a 3.5 inch black Vantec Nexus fanbus. I'll run the power along the coolant hose between the PC and the radiator to help keep things clean-looking. The benefit here is that the fans will tun on with the PC, and I can control the speed of each fan individually. It's more expensive than using diodes, but it offers much more control over fan speed/noise.

JWFokker · 02-12-2005, 02:46 PM

Those damn Yate Loon fans are out of stock everywhere. Stop taunting us with those kick ass pictures. I might have to settle with the medium speed transparent blue Yate Loon fans (1650rpm, also used in Forton quiet PSUs) and just undervolt them.
