80mm to 120mm adapter

[Dragoon42]

I ran across these, I was wondering if anyone has used them before? My case only has room for 80mm fans, but I wouldn't mind being able to upgrade to 120mm. I'm still thinking that since the opening is 80mm big then it would hinder the performance of a 120mm fan?

I've been trying to find 1 locally to give it a try in my case on the side panel. They are cheap enough but shipping sucks for them.

The way I'm thinking is that even though the opening is just 80mm if the adapter fits snuggly than you can get decent cfm without having to have a turbine of an 80mm one.

Those high step adapters can have pretty high back pressure, but if you draw the air thru them rather than trying to push the air thru them, then it seems to cause less restriction. This didn't slow the fan down much if any, but it's not such a big step only 80 to 92mm. SVC and jab-tech will sometimes ship by first class mail to keep shipping costs down on small orders - $6.19 shipped from SVC.com.

The one I used for a while was not really as effective as just using the original size fan.

I used an 80mm to 120mm on the back of my Lian Li PC60APLUSII case and it seems to work well when I had it running. The fan still had the same blowing, in this case sucking, power as if it were in the back of the case. I am not sure which pressure I have going on, but there are only three air paths, 120mm intake, 120mm exhaust and the tiny exhaust from the X1900XT video card blowing out the back. The heatsink fan blows directly to the exhaust fan so it promotes the air getting sucked out that way.

i've got one. i used it to swap out the stock 80mm fan from the stock heatpipe amd heatsink for a 120mm fan. i tried two different 120mm fans, one silverstone and one coolermaster. left all three fans at full power and actually saw a 1 degree drop with the 120mm fans. it was quieter, but not by much. for the adapter to be effective, look to a fan with 100+cfm. one of those 200cfm delta fans would probably make a huge difference.

I use one at the back of my Lian Li 7077 case. It works very well. The 120mm fan moves a lot of air at a low noise level as it should.
