I decided that my front case fan<80mm> is inadaquate so I decided to try out the new 80mm Delta 68cfm. I got it in today and installed it and my case temps dropped to 22C witch is 1C off from ambient room temp and my CPU went to 26C idle and 28C load. That Delta 80mm is a freakin turbine engine and I was about to take it out and try a different fan then I started wondering. Where my intake on the front is, are holes where the air gets through and I know that obstructions in an air flow will cause noise so I took out my nibbling tool from Radio Shack and cut out those holes for 1 hole big enough for my 80mm Delta. I remounted my Delta to the hole and started it up. I think I cut down the noise by about 1/3rd and the air flows into the case even more then with all those small holes. My case temp before this mod would flux between 22 and 23C but now it's ROCK solid at 22C. I also got another 120mm YS-Tech fan for my DD cube radiator. Now I mounted that one on like the other one, I have 2 on it now, so that one pushes the air through and the other sucks out what is pushed through. I used Zip-Strips to mount them. Now my case temps are 22C and my CPU runs at 23-24C idle and 25-26C load. I cannot believe that 2 fans and a hole cutting would do such a great job in cooling. WOOHOO FOR ME!!
