Do you really need to put bigger stuff to cool things down?

post #1 of 26
Thread Starter 
I been trying to finish upgrading my computer build using liquid cooling components but there's always a problem of not having enough space to cool things down. As you know, I really don't like big computer cases. I'm into mid tower computer build. I've seen so many modders here cutting things up just to put those big radiators.

I've seen this review not long ago of PNY's GTX 580 Liquid cooled GPU & CPU. In that review, a thick 120 mm radiator was able to cool down a GTX 580 as well as an Intel Core i7 870 CPU. Not only that, it was able to overclocked it & got what was described by the reviewer as "The best overclock results we've achieved on any GTX 580 model".

http://www.pureoverclock.com/review.php?id=1354&page=18

There's been a lot of people here & on some other websites asking if a small 120 mm radiator can cool a GTX 580 & almost all the answers were "No, you need to have a bigger radiator" (even suggesting as to have at least (3) 120 mm radiators to cool things down.

Do you really need to put bigger stuff (even if you need to destroy your computer case in the process) to cool things down?

No, but a larger rad surface means you can use slower fans to achieve the same effect. Rad size is just a variable in the equation for cooling performance. There are other factors that determine your overall cooling performance.

So why are this people here so anal about getting bigger stuff? I even read a forum thread here where some people described hybrid liquid cooling as fake.

Aesthetic is as important as the overall performance of the computer.

What do you mean hybrid?

And people are anal because its better to give yourself a margin of error by buying too much cooling than too little.

think of it as this, you have X amount of heat yuo can dissapate with different ways, small rads but with some crazy hight speed fans (gentle typhoons) or you can get large rads and use regular high static pressure fans

since you like small, you can get a 240mm rad, and some super high speed gentle typoons

Also, crazy high speed fans = more noise.

Consider this, with a 120 rad lets say to get out to a certain temp requires the fan to be on 100%
With a 240 rad, to get that same temp the fan would be at 50%

This is overly simplifying it, but it puts the point across. More surface area better coolingcompared to half the mass. With that, you can run the fans at a lower speed, less noise.

This. I have two 3x120 mm radiators in my sig rig. The fans are as low as they can go and it stays cool even under extreme use.

Like they said above, it's a trade off. One 3x120mm rad cooled my system but I needed to use higher speed fans and I didn't like the noise.

Plus, Two 3x120mm rads are cool.

(Pun intended.)

What if you just like to liquid cool a slightly overclocked set up. Can you liquid cool a computer using the smallest radiator possible & get a desired effect better than a typical slightly overclocked air cooled set up.

The reason why I'm asking this this is that I'm trying to liquid cool my computer with aesthetics in mind & not mainly to be able to overclock at higher level.
