dtek cooler core vs dangerden heater core
 

whats the diff? they look similar enough in size..anybody got any experiences/information to share?

same thing just different color and dtek has a opptional fan shroud

Since they are literally the exact same radiator, there is no difference.

However DTek does paint theres silver, which is nice (and no it doesn't effect performance one way or the other).

yea i belive they just paint the sides top and bottom not the acctual fins themselves

you could get that same rad from nappa for $25 but you would have to solder on your own barbs. so it would probably cost you $30 if you mad it yourself +shipping. i personally say get it done for you if you can spare the $5-7 =)

its a chevette heater core.

I don't live in the US unfortunately..and those heater cores you guys mentioned are near impossible to find..:(

anyway, so these 2 cores are EXACTLY the same? looks different on their website though..the dtek one looks real sweet..the dangerden one looks 'orribly ghetto :D

remember the Dtek is painted. take a look at Mashie's DDen heater core. it doesnt look so bad once its painted.
the Dtek and DDen cores aren't exactly the same, but they do have the same dimensions...

yeah wow..its perrty after its painted :)

so does anyone have any idea if they will both perform similarly..i mean..the dtek one says "The Ultimate Radiator. Heater core performance with Twin brass tanks, copper construction, Highly louvered fins with peak airflow spacing, Deep-well drop seam header grooves that create the best tank to header fit and modified with soldered 1/2" hose barbs for easy hook up and the tanks and sides (NOT THE CORE) painted silver. This baby will remove all the watts you can dish it. It can fit in most cases with ease" sounds all fancy and everything..and dangerden's one doesn't even come with a description???

i'm thinking of getting two heater cores and running both in series/parallel..don't know which one to get..:shrug:

is there really a need for 2 heatercores? there would have to be ALOT of heat to warrent that much cooling capacity...btw there both the same sept for a few accesories...i would get the painted dtek with shroud just cause it would save a lil work

i figure two radiators should increase the cooling capacity of the rads more, so that I can lower my cpu temps? no?

from my limited understanding of thermodynamics is that u are still basicly air cooling...ur just air cooling the water so u are still affected by ambiant temps...so the only way to go sub ambiant is too use tecs....and unless u where stacking tecs i dout u could over power a heatercore(with 2 fans running at 12v with shrouds)....could be wrong..usualy am:dome:

you can't get the water temp below ambient with just radiators and fans.

with two radiators, remember parrallel will reduce the flow in each rad, which is better for the rad, and lower overall loop resistance so there is a higher flow through the block. So it is better all around. Also, you have twice the surface area, so you can run quiter fans and still get good results

I never intended to get below ambient! I'm just trying to get as near ambient as I can :)

yeah. probably gonna take your advice and do dual heatercores in parallel :) hey Brad i'm also taking your advice in your other thread about the 1060, and figured especiallly now with 2 rads, i would need a more powerful pump..the 1060 should be more than enough right?

if you run the rads in parrallel you will be lowering the resistance, so even with your current pump you will get a higher flow rate. I'd just do that at first, and if the temps aren't that great, go for a bigger pump

when u run them in parrallel u use "y spliters" right?

ok. now i've more or less already decided to get the 1060. ie. flow rate shouldn't be a problem in the main loop. but I want to lower the flow rate in the heater cores..will running them in series or parallel create lower flow rates within the rads..

mm..another probably silly question: is coolant flow in an entire rig ALWAYS the same THROUGHOUT the loop, or can it flow faster at some parts..and slower at others..? :D

what the hell happened to my physics knowledge..hehe :cry:

well it cant go back up once it goes down....but it can keep going down.....

mm..were you talking about coolant flow..or my physics knowledge? :D

lol both...:p

lol! :D

anyway, so you're saying coolant flow in the ENTIRE rig is only as fast as the slowest point?

no im saying that the only time u get what ur pump is rated for is right when it leaves the pump....as it goes threw blocks and tubing it loses speed...only way it gets taht speed back is if it goes into a drop in the tubing.....but the flow rate will almost never go back up

Correct.

Flow is constant though the entire loop (assumeing you don't have paralell lines or different ID tubes for some reason). Furthermore that flow rate is determined by the resistance of the entire loop. Since the only thing that really resists in most setups is the WB, this determines the flow rate (more or less).

Obviously if it changed speeds at one point you would have a few problems. Amoung them would be trying to teleport through the water in front of them.

Parallel.

thanks for the helpful advice :) anyway, so in parallel..is theoretically the amount of flow to each rad HALF of what goes on in the rest of the rig?

eh, the flow rate may be the same, but the velocity of the water can change. if you run two rads in parrallel, the velocity will decrease as they enter the 'Y' splitter, and increase as it converges after the rads. a good analogy would be a river that got wider in the middle, and then narrowed. the water would move slower in the middle (even tho the flow is the same), and would speed up as it got narrower.

okok..somebody refresh my high school physics for me. what is the definition of flow rate? whats the definition of speed? (i thought they were the same! lol :D)
