What's a shroud?
Related to water cooling (I just read the term in the water cooling forum). I googled and can see what they look like, but I don't understand what they do. Should I get a pair for my kuhler 920?

they are like a spacer... you can make a ghetto one by removing the fan blades and hub from an old fan.
whether they are useful depends on the fans static pressure and the fpi of the rad. I personally don't use shrouds as they take up too much space  yeah... beat Creekin

Hmm ok. Thanks for the explanation. I'll probably not get any for now then. I have about 30 million old 120mm fans (ok, maybe not that many), so I might do some experiments, though!

 the main purpose is to reduce the size of the dead spot created by the hub of the fan. old fans with the guts removed make perfect shrouds  personally though i dont bother with them. http://www.coolingtechnique.com/mart...ng-Review.html

Hahah. Thanks Creekin; that's the article I just read (you linked to it in another thread) and made me ask the question
 Edit: it's a very good article (nice methodology) and I've bookmarked it Last edited by Psychotria; 2nd May 2012 at 11:03 AM. |

A shroud forces the air to go through the radiator. Without it, the air will just go around it because there is less resistance.

Everything is becoming clear now... well, as clear as mud anyway
I think the best thing for me to do is dismember some of my spare 120mm fans and see if shrouding makes a difference for me!

This roundup may help choosing a radiator fan;
http://www.tomshardware.com/forum/33...g-roundup-2012 Although I have nfi which charts to look at Restricted CFM test looks like the logical choice for pull fans, db tests are at the bottom. The Gelid wing's look good though, and come in a 4 pack, there's also a deal on Scythe 1850 GT's here if your after 4 or more.
