I recently read an article describing the effectiveness of 60->80mm fan adapters (or rather, the lack thereof). One problem they mentioned was that maybe the act of reducing the hole was increasing the back pressure enough to make the fans ineffective.
So, I was thinking about trying to make a shroud for my Taisol CGK760092 and then setting up an 80mm Panaflo L1A on it, but in suck mode, instead of blow mode. I am hoping this will relieve the back pressure problem. But I have a couple of question in this regard:
Should I have some head room above the Heatsinks fins, and if so, how much?
How far down the sides of the HS should I bring the skirt?
My basic assumption is that the shroud will help bring air in at the bottom of the HS, which will give allow the most air contact with the HS. I also believe that I need to allow enough open space to allow the optimum volume of air into the HS. But, is there a good way to calculate this, or is it a "poke & quiver" problem....?
Any thoughts would be appreciated.
Thanks.
