how much lower will i get with better pump?

[nigely]

I own a L20 and if i switch to L30
will i get any difference?

Did anyone actually do any test on how flow rate affect performance?

let say from 1046 to 1048 to 1250

The difference depends on your components and current flowrate, among other things I can't think of :-/

Yup... without knowing what your currecnt setup is, it's hard to tell. We especially need to know what type of CPU block you have as flowrate is critical there.

There is a sticky on 'flowrate' in this forum. You might have a few questions answered there. Also check overclockers.com for some great articles on the topic.

My experience with going from a 1046 to 1250 was not that much difference (I couldn't say whether it made any difference since I can only go my mobo sensors). Any difference was well within the margin of error. Though my waterblock (Innovatek rev3.0) is not the best model to take advantage of a higher flowrate.

With a cascade or WW, I would have probably seen alot better improvement with the pump upgrade.

Having said that, imho I'd say the money is always better spent on a bigger radiator and quality fans rather than popping 50 quid on a pump.

Let me tell you something.
I had a L30 for about a week. I ditched it over for an Eheim 1048. Why? - The temps are excatly the same from my expriment, also the L30 is much louder then the "dead" silent 1048.
I'd stay with the L20 it's really compact and it's almost as silent as the Eheim.

Suma.

True...a higher flowrate usually won't produce incredibly better results unless you're using a waterblock like the WW or the RBX. You also have to factor in the increased heat a bigger pump brings...

I think you'd be better off installing another radiator or something if you can. But it'd still be nice to know your setup.
