I cored out a 92mm fan I had laying around. I made it into an hollow 92mm extension piece. I installed it between the 92mm to 80mm adapter and the Thermaltake UFO 92mm fan. I just wanted to see what would happen, if anything, to the idle/load/and case temps, and also if it would affect the db's coming from the fan.
While I don't have access to a db meter, audibly the fan does sound quieter, but just by a little bit. The idle temp went UP by 1C, the load temp went UP by 2C, and the case temp went up by 1-2C, no matter if it was under load or not.
I thought perhaps the added length to the air pathway would create a more laminar air flow and be more efficient, I was mistaken....
On a side note though, after I recorded these results, I did remove the Arctic VGA Silencer from my ATI Radeon 9800 Pro video card. I took the time and lapped in the heat sink, applied a good thermal compound and re-installed the video card. After that my case temp and CPU idle temp have recovered from the earlier CPU ducted fan experiment. The CPU load temps were unaffected and are still 2C higher than before.
I'll be going back to the earlier configuration after I lap the CPU heat sink in. I hopping for an additional 1-2C improvement in the LOAD temp after the heat sink has been lapped in. We'll see.....
