need help for 60mm to 80mm or even bigger converter!!

[RockRock]

I am planning to use bigger fan instead of my existing 60mm HSF. Which size is the best? 80, 90, 120?
Where can i buy the converter? Is there any web site which shows you how to make one by yourself?

Thank you for your help!!

Here is where I got mine for a Alpha P3125.

60mm to 80mm/92mm fan adapters on For Sale/Trade Forum

The construction is a little flimsy, but then again, mine was a beta. A bit of duct tape fixed it quick.

The advantage is the ability to use a larger fan to get the same CFM, but less noise. 80mm seem to have the best CFM to noise ratio out there.

Now after a certain point, you run into diminishing returns with larger fans. A 92mm or 120mm may give you more CFM, but it fails to gain you anything else in cooler temperatures or in o/c. Where that point of diminishing returns is located varies somewhat. However, looking at overclockers.com, it seems that the difference between 33CFM and 38CFM on a PEP66 is negligible.

That being the case, an ADDA 92mm @ 41.6 CFM and 30 dBA would be a good choice. That kills the Delta 60mm @ 38 CFM and who-knows-what in the noise department.

For my Alpha, with two fans, then two 80mm @ 26 CFM and 23 dBA (or 52 CFM total and 26 dBA) works just fine.

Make sure that there is room in the case for the larger fan.

I made a 60 to 80mm Adapter for my GlobalWin FOP38
similar to this tutorial.
Next I will make a 60 to 92mm Adapter. The Panaflo L1A with 42.7cfm at 27 dBA
should be perfect for my CPU.
