push vs pull charts or stats

post #1 of 6
Thread Starter 
Hey so I'm looking at getting around a 60mm rad.

Something like this:
http://www.performance-pcs.com/catalog/index.php?main_page=product_info&cPath=59_457_667_668&products_id=32497

or this:
http://www.performance-pcs.com/catalog/index.php?main_page=product_info&cPath=59_457_667_1075&products_id=32768


So I know push/pull doesn't offer much benefit for an AIO cooler but will there actually be some benefit for a thicker rad like these?

Also does anyone have a link to some graphs or charts with real numbers for push/pull on custom rads like this?

Thanks.

Of course...Google is your friend. wink.gif


I hope this helps. smile.gif

Ha yeah I was actually looking at another post by him right when you sent that. That test is only with a single rad I wonder if a bigger one would see more of a benefit.

I think you can extrapolate the results as far as determining if push is better than pull or push/pull. A bigger radiator would only make the delta bigger, but the push/pull configuration differences should still hold true.

The conclusion from the link I posted:

CONCLUSION
Shroud benefits are very much radiator specific. While the MCR120 shows only very minor benefits in pull condition which are nearly immeasurable, the RS120 shows very dramatic benefits of 1C in pull condition. My first round of shroud testing only tested on one radiator with two fans and found gains on both. That test appears to still be good, however this round in testing a different radiator it has become clear that the benefits can not be generalized across all radiators and that shrouds on some radiators in the right conditions can even hurt performance. The MCR120 was generally a better performer in push condition without shrouds.

About the only generalization is that push/pull is still your best bet if cost is not a problem and that will hold true for all radiators.

Bottom line:

Shroud benefits are Radiator Specific!!!
Are shrouds a performance benefit and should you use them for your build? MAYBE…smile.gif

Okay thanks for the info.

based upon MLL's testing

Pull is better below about 1500 rpm
Push is better above about 1500 rm

P/P will give about 21% (maybe as higha s 30%) more cooling over just 1 fan.

You get very little benefit from increased radiator thickness as you can see here:
