anybody have a copy of the images like they use to have in leakycar.com?
I'd host them with the table hosted here

I didnt say that quite right. What I meant to say was try this:


CPU in series with GPU and NB

vs. this

CPU in series with GPU and NB in parallel


and see if the CPU flow is significantly slower when all are in series. If so, choose configuration 2. If not, leave them all in series. Hope I explained that ok. I tried putting some arrows and all in the post but when I posted it they wouldnt line up right.

Significantly slower? No... Try to work some numbers. The pressure drop is half of that of the NB or GPU block @ system flow. Assuming we're using Swiftech's, at 7.2" drop at 1GPM. You're using a Mag 3. Your CPU block is a Swiftech as well, at 8.6" drop. Work out the difference in CPU cooling. I doubt it'll be measurable. Your NB and GPU will both suffer from the reduced flow more than they'll gain from the lower inlet temperatures. You're correct, although stupid. :p J/K, obviously. The CPU gains are small, if measurable.

Really? 40C? Yow!
It's surprising to me that they bother to specify 6 l/min. I had the impression (from Bill Adams' Radiator Heat Dissipation Testing) that, above a certain fairly-small minimum, coolant flow didn't matter that much - particularly for the flat-tube radiators.
40C... so in a 68F room, the coolant would be 60C/140F? Of course, to the extent that you weren't trying to dissipate at their rated number, that temp should fall.
OK guys - you're totally right. There might be numbers, but they're not all the numbers and so qualify as "marketing-speak". Maybe they planned to remove these partial specs from all the web pages and the one I ran across was an oversight...
IMHO, folks choose these radiators (and the thermochill 120x1) because theyfit. I don't think a "real" set of performance curves would hurt sales at all - and would help with things like fan selection.
I've a couple of PCs "out there" with BIPs in 'em (coupled with Eheim 1046, Panaflo L1A at 5V, Swiftech "old style" center inlet blocks). For silencing a system, these work great (one of the above systems is in a recording studio - not on the same side of the glass as the mikes, but noise is still an issue).
Bob
PS: I'm a software guy who got into this because noise really bugs me...

i believe it's a standard differential for domestic radiators (i.e. the ones in your central heating system) where 40C differential isn't quite so off the scale....

Hey guys, what do you all think about the new DD Maze 4 chipset waterblock? I've been looking at it and I think it looks pretty nice. Plus it has a mounting option for the stupid chipset hooks on my mobo :mad: :D

*edit* BTW, I still can't get that heatercore cross reference site to work http://www.autopart.com/radiatorinfo/heatercoretech.htm. Is everyone having this problem or is it just me because I'm doing something wrong.

All I can say about the chipset block is: "It's about time." It has an incredibly low pressure drop, and cooling that is good enough for the chipset.

works ok for me (on a 2-342) - could it be that the core you were looking at isn't in their database?

Yeah it does work for you. I just tried that heater core (2-342) and it worked fine. Why is it that the only heater core I pick, out of that list of hundreds is the one they don't have :cry: :cry:. I thought I tried a different core before just too see if it worked and it didn't though hmmmmm...... that must've been before I knew what #'s to plug in.

*edit* Ok..... I just tried it with other core #'s and so far your's is the only one that actually brought up any results. What a helpful tool :mad: lol.

*another edit* I found some that work. It seems that most of the 2-700's don't work, grrrrrrr.

While we're on the topic of heater cores I might as well ask..... does anyone know of a heater core that is equal to or a little less than these measurements - 11"L x 5 3/4"W x 2"D? The 5 3/4" measurement is really cutting it close :eek: because the core would have to fit in my upper drive bays which I'm sure all of you know are also 5 3/4". I'm basically looking for one that can fit two 120mm fans, and has both barbs on one end. So let me know if you know of one that is close to these sizes. Thx

Mine is 11x5.5x1 I think... two 120mm fans are on it right now with only a little space left over.

Part #s on the sticker are 826H2303 and 21030

I don't know the part # that was ordered. It was purchased from LeakyCar.com which is now down... :cry:

Edit: I found the part # in an old e-mail... # 2-302. Hope that helps.

Oh... here's a picture I took of it when I got it.... and yes... I have it in my upper drive bays. :D

OOOOOOOOOOOOOO, I'm happy now :D. That's honestly the last heater core I looked at before I went to go eat. Then I come back to my thread and you've posted an actual picture of it (vs. small black & white drawing ;))!!! It's the best priced heater core that size that I found because most of the others that were aprox. this size where $40-70!! I think this is the one :D. Just a thought though.... anyone know how this beauty ;) would compare to a Black Ice Xtreme II? I'm just wondering. I'm more than likely throwing the idea of getting a BIX II out the window :D. I mean this thing is $20 and that BIX II is $100!! I'm getting excited (can you tell?) :drool:. Thx for the pic!!

BTW, here's a picture (ahem....drawing) of the heater core that was in the database.
Note: It says it's 2" thick versus 1". 1" sure would've been nice though :(

SnowRider,

Honestly... It may be 2"... It's in my system now and I haven't measured it that direction in a LONG time.

I do seem to remember it being thicker than 1". ... I just pulled the side of my case and checked... yup 2" thick... my mistake. :D

Hey TimeLord, I have a favor to ask. Do you think you could measure how long that core is overall? I'm pretty sure that these dimensions (10 1/2" x 5 5/8" x 2") are just the fin area and I need to know how much those tanks on each end add. I thought of that just now and am worried that they'll add to the length so much it won't fit in the top of my case. I could be in big trouble:cry:. If you can do that I'd really appreciate it. Thanks

as far as i know all measurments are for the fin area only.

I believe they add from 3/4" to 1" to each end... I will make measurements when I get home in a bit and post final measurements here for you. ;)

Welp... smaller than I thought... Front cap only adds ½" and the back cap with the inlet and outlet only adds ¾".

Total length of the whole thing is just a little under 13¾". So, according to my calculations... the fin area is bigger than I thought too... must be 12½" not 11½"... my bad. I think there was one that was 10½" though. I just don't have the model number. Sorry.

Hope that clears it up! :D

Awwwwww crap. Just what I was afraid of. That's to big. The maximum possible length I can have is 11 1/2" and that would be making things really, really tight. See, the length from the PSU rack to the front of my case is 11 5/8" so that's pretty much what I have to work with. I've thought about making a big shroud type thing that would screw onto the top of my case (it would look kinda like the Koolance setups) but I don't think I trust my modding skills enough for that. I'm not sure, I'll keep considering it.
Well, thanks for measuring that for me. I'm glad I was able to find that out before I rushed out to buy one. Now back to the HC Database to find a different core :cry:.

christ, buy it and take it to a radiator shop and have them cut it to the length you want, and resolder the header on the end

I am looking at 2-274, which is 9.8" x 6.125" x 2", with 5\8 (1\2ID tubing) barbs. $21 at autozone.com. GDI # 399026 THis may suit you better. SHould fit 2 120mm fans perfectly.

Brian

BillA, I didn't even know that they would do that. Thanks for the tip. I was under the impression that the radiators were touchy beasts and could not easily be hacked.

the corrugated plate heater cores are simple,
the tube type are more difficult as the header perforated sheet must be recovered and reused

Hey guys, here's an update on what's been happening.
____________________________________________

I just bought a PolarFLO CPU block and a PolarFLO GPU block. Both are the copper plated versions and I got an EXTREMELY good deal on both of them. Basically, what I payed for each block is what I would've payed for CPU and GPU blocks made by say, dangerden or swiftech. So I'm very happy :D :D :D
PolarFLO has the best customer service I've ever dealt with period!!! IMHO they are 2nd to none when it comes to customer service. I recieved quick, helpful replies to my emails, and was treated like they cared about me versus taking the quick route around things. Steve @ PolarFLO gets huge props for helping me out.... Thx Steve!
After that shameless plug :p, onto the new parts I'm thinking of lol.
For a reservoir I'm probably gonna buy one from shelbykim0 of eBay. She's been mentioned in these forums a few times and her reservoirs are basically like Criticool's "Waterplant" reservoir except that..... she'll make them in custom sizes with custom barb placements for you :D.
Another change I made is the pump. I'm now most likely gonna get the "AquaXtreme 50Z-DC12 Mag Drive Inline Pump w/ 1/2" Barbed Fittings" (the name just rolls right off your tongue huh? lol). It's the exact same pump as the Swiffy MCP600 except it's all black!! Suuuuwwwweeeeeettttt!!
I'm still going back and forth between what fans to use, and whether I'm gonna use VW/Audi antifreeze or one of the Zerex Coolants (either the super coolant or the super protector which is clear).
I'm really busy right now because I have a new job with crazy hours so I have less time to think about all of this stuff. I am going to try and make a new diagram showing the updated placement of things.
Here's a pic of the copper plated waterblock tops minus the baseplates and barbs.

I just received my waterblocks yesterday and man are they pretty looking :D. The blocks where shipped in a small box within a larger box filled with packing peanuts. It'd be very hard to damage them during shipping. With each block PolarFLO gives you some hose clamps, the mounting hardware, and a Y-fitting for the CPU block. I tried my best to take some pictures of the blocks but it's not easy as I thought it'd be. The lighting is very hard to get right. Here are the results anyways :rolleyes:
