Hello all,
I am using a Antec900 and I have a question about fans and CFM. I recently replaced my thermalright 120 ultra extreme cooler with a Zerothem NV 120 as the thermal right would not allow me to run a side panel fan which really helps with temps in my experience. In any case I have my Q6600 running idle at 35-36c with speed step enabled. and 66-67c prime95 full load 6 hours. I experimented with three 120mm side panel fans.
1) Thermaltake 120mm fan 78CFM Loaded temp 68-69c fully loaded 2 hours prime95
2) Thermaltake silentcat 120mm fan @ 67CFM Loaded temp 68c fully loaded 2 hours prime95
3) Scyth Flex 120mm fan @ 42CFM Loaded temp 65-66c fully loaded 2 hours prime95
All temps monitored with latest core temp program
Now I thought a higher CFM fan would lower temps not raise them?
Why is the lower CFM fan cooling the best?
If anyone has an answer I'd like to hear it.
Thanks,

BTW the Zerotherm with side fan is 2 degrees cooler than my thermal right without sidefan
