Changed vid card today and have the case off till everything is working nominal so haven't noticed yet. Put a slot fan under the V3 3000 too. Lots of air. Just feeling around it by hand there's more(make sure it blows the same way-down into the hs) air for sure. The numbers say there's more cfm, less rpm and less decibals.
its showing 18-20c now whereas it used to be 20-22c--could be the basement cooling down though--the aopen temp sensor isn't on the cpu
