Bigger radiator does not mean better. A 480GTX will curb stomp that radiator any day

ROF*****!!!!!

ur joking right?

This has been attempted and posted by many times. They had this and a 16x16 120mm fan radiator at P-PC (or was it moddersmart) and the thing is, these things are not optimized for water cooling computers.

umm... concept seems totally lost on me....... bigger rad, heat spread out across larger surface area = not as much air flow required.....

... i mean, i guess what ur saying is that once u get so big, things start going backwards... like a black hole?

It is not just the surface area that determines the flow of a radiator/heatercore. Things like fin density and restriction way in heavily. If the radiator is thin, it will be like a thick smaller radiator that was flattened. If the radiator has high restriction, temperatures will greatly suffer. If the radiator has high fin density, fans may not have enough static pressure to pull air through. The reason the concept bigger means better exists right now is because these are bigger radiators based on the same optimized technology of pc cooling and therefore keep relatively similar flow rates and fin density.

that depends, theres no denying that the GTX's 20FPI are a large part of its 80+ CFM optimization, which isnt necessarily a bad thing.

i kinda have 2 disagree, noob, while flow through the radiator might differ from that of a "pc" radiator, i can only think that more time spent n the radiator would help the output temps... am i wrong?

i really doubt the fin count on a auto rad would b greater than a GTX's... hell, at that point u could just mount the rad 2 ur ceiling fan 4 air flow.

i just don't c how bigger can't mean better, just cuz it isn't "optimized" like u say. it's still able 2 cool a hella high wattage load below 150°F (if no thermostat is used). i'd bet money that a good auto rad could cool a 1000 watt heat load better than a 480 rad... where's martin when u need him

Basically, people have tried this before and it did not turn out any better. Here is the one that I was referring to BTW...

In the event that I am wrong, I will be more than happy to admit it!

A lot of guys have tried small car rads, the thing of it is the channels in it are pretty large, with our little pumps we don't have enough flow and head to keep the water turbulent through the rad...The flow will turn laminar, thats where the heat pulls back into the center of the flow leaving the cooler water touching the outside of the channels..Thats not real good for cooling..You need turbulent flow through your rad to dissipate heat well..Not saying you cant use one, you can, its just you wont likely have any better performance with one then a smaller HC or rad...

A made for WC'ing rad has flattened tubes, that keeps the coolant in contact with the outer channel walls, that makes for better cooling...The more turbulance that you can keep through your rad and blocks the better they will pick up and release heat...The less turbulance the more likely that your flow will turn laminar...

Unless they have changed those Magicool rads they are just 3-360 rads with a cover stuck over them..So you would have the restriction of 3 rads..

You can find some pretty big HC's i this list, they would be better then a car rad....Find The Perfect Heatercore

Ah there is the official scientific explanation!

If you have an Iwaki RD30, would the scenario change in that situation?
