My local PC parts supplier called me up yesterday, Asking me if I wanted to test out a Corsair H70 in my PC.
I must say it was very easy to install and so far upto now it is cooling things down very good. compared to my Noctua NH-14D I think the H70 its a little better especially on idle. load temps are similar. At the moment I have the fans push pull from inside the case, corsair recomend push pull from outside the case to bring cold air in.
