Should we be looking at transmission coolers instead of heatecores?

[Becks]

What is the measurements of the finned area? You got the 9.75x11.75 one, right? I'm wondering if I can fit 4 120mm fans on the 11.25x11.75 one... it would basically have to be the side panel of my case heh... would look interesting I guess..

[Ruiner]

btw, JM, what is the core size of the cooler you chose? I heard mention that the size listed on the site includes the barbs.


Edit...oops, that question was asked one post above.
Consider this a bump.

What are the turbulators?

I know they are aluminum and BillA says they are good but what are they?

Make turbulance seen a pic of one that was supposed to be placed between a fitting and a tube of a radiator and it looked like 4 or 5 teeth in a circle. Dunno if they swirl the water around in a circle or what. But the make more of the water hit the sides of the tubes making heat transfer more efficient.

So without turbulators in a perfect world water would go down a tube and only the water around the sides would hit the tube and get cooled, the water in the middle wouldnt get cooled as much. Turbulators help prevent that so to speak.

I see. Now if they would only make one with no aluminum in them we would be set

I'm going to be upgrading to an extra huge 13.75"x13.93" copper Honda Civic radiator so I can mount 9 120mm fans to it. That's the finned area, btw. I think I'll invest in some Panaflo's. The Sanyo's are nice but they don't get quite quiet enough, even at 5V, but then again, I don't have a shroud on it, they are right up against the radiator....but I figure with that much surface area I could undervolt even an L1A and get decent performance temperatures out of it. I'm shooting for killer temps at near silence. It seems sheer size is the way to go.

I'll be compensating for the reduced flow with a second Mag 3 in series and building a proper reservoir that I can mount a Mag 3 directly onto.

The transmission cooler is good for a quiet setup because I get equal performance from it compared to my old 2-342 heatercore, even at a reduced fan speed, but the one I got wasn't big enough to attach 4 fans to so I really didn't benefit much.

At least I've got a reason to buy more hardware now.

Thats a hell of a rad ur gonna get there. Be warned about the mag3's. They do leak after time. They seals go bad on them. So if you inist on using them, open them up and reseal them with some quality grease and make sure that they pumps are not near the components. Or have it so that if the pumps leak its not the end of ur comp.

Exactly what do you mean by "near"? My quiet-but-audible rig's Evercool 120 (yeah, I know) is the loudest thing in the system at 5V. At 4V or less, it drops below a Seasonic Super Silencer 350 Rev A3, but the PSU remains audible.

Well, sheer frontal area, anyway. I think you'll find L1As, particularly eight or nine L1As together, to be no where near silent, even at 5V.
I'd suggest a shroud on the pull side. If you allow enough plenum, you should be able to use just one or two 120mm fans (see this thread for a discussion of 120mm fans - and follow the link posted there (or the copy of it I put here) to the SPCR quiet fan roundup.
Finally, think about putting some acoustic-absorptive foam in the inside of your shroud - so at least the off-axis sound from your fan(s) will get a bit attenuated before it goes out through your radiator.
Oh - Greenman100 has offered to make custom shrouds - so don't let any possible lack of familiarity with sheet metal stand between you and a shroud.

With the 11.25x11.75 tranny cooler you could definitely fit 4 120mm fans. The 9.75x11.75 was a few centimeters too narrow. It was perfect for length though.

I know all about the Mag 3's problems. The first thing I did when I got it was replace the o-ring with RTV silicone sealant and I only use nylon fittings with teflon tape.

Hmmm. Maybe I should use a really big, slow moving AC fan. If I can't find a suitable candidate for that, I think I'll get the Papst 120mm 4412FGL. They're supposed to be better than the 120mm L1A's at reduced speeds.

[JamesAvery22]

JWFokker post pics of that radiator =) Thats exactly what I was planning on doing before I feel in love with baseboard heater pipes

Have you thought of making a large duct from a blower instead of using a bunch of little fans? or even ducting a 12" window fan? I was either going to make a box with a window fan or a blower to move air through it. Using 9 120mm fans seems kinda... I dunno misplaced effort. The bigger the fan the better I say

[Ruiner]

Just get the civic fan that matches the radiator...then build a rad box with all sort of ricey styling elements.

I was looking into radiator fans also. You can pickup a 13" radiator fan for like 40$ but the thing is the absolute slowest one I could find anywhere was 650cfm and it sucked like 7A at 12v. Doubt even with a controller you could make it quiet.

[JWFokker]

I can't imagine 9 L1A's could be very loud at 5V. There's no way. They're only a bit over 20dba at 12V. At 5V they should be barely turning. Of course, both the L1A and 4412FGL are both stupidly expensive. 9 fans would run me about $150....

Yes I understand that every time you add a fan it increases by, what 1.5dba or something? It still won't be very loud at 5V.

[Bad ConNecTioN]

With two fans, comes double the output....3dba

um, I assume you are talking about the Panaflo 120L's which are 30db @ 12V.

Whoops. I was looking at the Nexus Real Silent 120mm fan on the SPCR chart. Too bad the Nexus and Papst are both so damn expensive. $18.00 is way the hell too much for any fan.

9 18$ wouldnt be very nice... More than double you paid for the radiator.

[JWFokker]

I really want a box fan for it, but they're noisy. Any ideas for a large quiet fan? I'd use a blower but they don't have a large enough surface area.

[Ruiner]

You could use a blower if you fashioned a duct to fit it.

[JamesAvery22]

If you have the depth holmes use to make a 12" window fan thats pretty quiet. Its like 10" thick though.

Thats what I was going to do.

[JWFokker]

Hmmm....I'll have to check on that box fan...

The problem with blowers is that they don't have a very large surface area. This is a 16"x16" rad, so a blower that would fit on a heatercore, isn't going to cover enough area for this thing.
