Should we be looking at transmission coolers instead of heatecores?
 

I found this on Ebay while looking for a better rad.

It's effectively twice as big as a Swiftech 676 and only a few bucks more. Granted, it would kill your flow rate compared to the 676, but with an appropriately powerful pump, would it be worth it? I would be quite nice to mount to the side of my case.

eh ?
its the same rad with more plates, in parallel (676, 677, then that one)
so it is less restrictive than the 676, not more
they are cost effective, but the shape is not too friendly

if it fits, go for it

Bulkpart has the equivalent Derale for $43.18. Think I'd buy new.

I wonder if they all come in inconvenient sizes. Have a look at the Derale catalog.
Any idea if these typically have "turbulators" or some such in the internal passageways? I've seen these in accessory oil coolers and I would guess that they kill water flow.

bah, killed my post

take a glance at the old rad article, turbulators work GREAT - but they are aluminum, use an inhibitor

size and price does not look too firendly.

I've heard of an oild cooler used before and looked into it and did not find much.

Inconvenient sizes? It would fit pretty well mounted to the side of my case. Those narrower ones would do well mounted to the top. Actually, if there were slightly bigger ones (13"x13" or better) I could get even more fans on it. As it is I should be able to get 4 on it and have some room to spare.

One person's poison is someone else's nectar. :) Well, maybe not as extreme as that - but you know what I mean...

We'll see if it beats my 2-342 when I get it in a couple weeks. I've gotta buy a G4 first.

Any news on this?

Found some nice looking copper core transmission radiators that have built in turbulators and are about 12" square.

40$ delivered isnt too bad.

They are the same ones bobkoure linked.

Heres the place that sells em though:

1/2" long multipass tubing with 3/8" ID fittings. Looks pretty restrictive and the turbulators probably make it a good deal worse. But with an iwaki Im betting it would do quite well. Nice and thin too.

use an inhibitor, the turbulators are aluminum

Well, I bought the G4 and a Swiftech GPU block....and another case of Bawls....so I'll probably order one tomorrow or Monday.

But damn, I really should buy the Star Wars DVD box set too...

I hadn't meant to link those but the stacked plate rads further down the page. :)
I guess if you've got pumping power to throw away, though...

Hell yes I do. All I've got my Mag 3 pushing is an MCW6000-A and (soon) an MCW50 GPU block. Through 3/8" tubing. Of course, I'll need to buy more Sanyo Denki's too.

This is the one I'm looking at. Should have an extra inch or so on each side, but it's just the right height at 9 3/4" (247mm). I'll have to start giving some thought to how I'll route the tubing for it. It'll be oriented the same way as in the photo, the inlet will be at the top of the rad and the outlet at the bottom, headed straight for the pump inlet.

Doesnt look too dif from the standard heatercore... Flat tubes with fins soldered between them...

MUCH thinner. Trans. coolers are usually in the 3/4" to 1" range on thickness. Most heatercores are in the area of 1 1/2" to 2"

Are those listed dimensions with or without the mounting bracket and barbs?

If its without Id guess it would perform about the same with quieter fans. Else I dunno.

Im looking at the large 12" x 17" ones but those are single tubes multi-pass ones. Iwaki here I come :D

My limited experience is that the major factor is radiator frontal area. However, I would guess that you do give up at least some performance when you reduce thickness. Beats me how much that would be.
You're certainly right about the reduced fan noise (again, from my limited experience).

Why not stick to the rads with multiple parallel water paths (so stacked plate or fin and tube)? Contra-wise, I guess you could cut the serpentine tube at either end of the fins and attach some sort of manifold at either side. Somebody's done this - think I saw it on overclockers years ago. Anyway, it seems like an awful lot of trouble to go to to get parallel (low resistance) flow when you could just start out with a rad with parallel paths in the first place.
By all means go with an Iwaki if you want one (I do, too) - but I'd suggest you use all that additional force to help transfer heat from the waterblock base plate to the water.

True... Guess I'll stick with two 2-342s...

Ordered it just now so I'll let you guys know how it is when I get it. Of course, now I need 2 more Sanyo Denki's.

The ones I have been looking at are the Derale Series 8000 single pass ones. They're plate and fin, and don't appear to be much different than the swiftec 676, but I haven't seen a 676 up close, only a lot of product spec. pictures. I'm not 100% on the overall size after the mounting stuff, but FWIW, the measurements I've seen on the smallest one is 6" x 11" x 3/4" Almost perfect for three 120mm fans after I figure out how to shroud it properly. Unfortunately they're solid aluminium. Also, they have 3/8" push on barbed inlets and outlets, but from the way it looks, you may be able to cut off the barbs and put on 1/2" barbs, though I don't know how well you'd be able to join new barbs to to the tanks since they're Al.

Also, Derale makes a plate and fin single pass that's 11.25 x 11 x 3/4 which I'm sure would do fine. I don't even know how you could fit anything bigger than that in even a full tower unless you're using an external kit?

I just got a lead from my local NAPA manager about a guy around me (Orange Cty, NY) who may have copper ones, though I don't know if he's going to have copper ones with copper turbulators, or if the turbulators are going to be Al. If they're copper/copper, I'll let you know.

I got the Derale 8000 series 9 3/4 x 11 x 3/4. I'm just going to bump up my antifreeze mix to 20% and hope for the best. But if you can find copper tranny coolers that'll fit 4 120mm fans, let me know. I don't really care if they have turbulators or not. I'd prefer not so I didn't have to worry about them.

It might be worth trying Zerex Racing Coolant, the manufacturer only recommends a 10% mix (so you get full corrosion protection) - and, as it's for the track, there's no glycol in it (there is some water-wetter, which IMO is unnecessary, but that shouldn't be a problem).
Are the Derale coolers all aluminum or is it just the turbulators?

I'll let you know. I haven't had free time from work during the day at all the last couple weeks, so when I get some, it's going to be the first thing I check. I'm honestly thinking about staying with a heatercore if I can't find an all copper tranny cooler, I just bought a G4 and IIRC, it isn't going to work that well with the types of viscosity that you're going to see with higer antifreeze concentrations.

As far as I know the Derale 8000 series ones are completely Al (plates, turbulators, everything). As far as Zerex goes, how much thicker is it than water? Never used it before. I was thinking about just springing for Hydrx.
