would this be a large improvement for the H70 seeing as people say it runs too loud?
also the sickle flow fans have a higher air flow of 90cfm compared to the stock ones that have about 60cfm would this increase the cooling performance significantly?
The best fan they tested at overclockers was 300CFM and it pulled the high temp down from 69c to 53c. So I would say 90CFM might keep it at 65c maybe a bit lower. Also if you use better Thermal Paste (such as AS5 or IC Diamond 24) that might help.
