Are screws supplied with that and will they fit in the h70 rad?
Why didn't Corsair do this to begin with? Even the H70 for the cost of them. There's lower end cooler with lapped contacts. :s
Acetek and Cool-It make these coolers, not Corsair or Antec for that matter.
I'm not sure if lapping the plate of something that is pretty flat already even really makes much of a difference. Because I lapped my CPU which gave me +10-15c degree drop in temps all by itself. I thought I was having issues with my H50 back in the first month or so when I got mine so wanting to check all options, I replaced the H50 with the stock AMD cooler which isn't lapped. I saw maybe a 1-2c increase in temps but for the most part there wasn't a difference.
In any case I do know that lapping the surface helps to minimize the surface defects and allow TIM better and more complete coverage to aid in the cooling process. Which is what lapping is all about.
As far as my example of how to set up a push pull, it was an example. It's not carved in concrete. You have to adjust accordingly in order to satisfy your particular need. Also maybe I was outlining how to set up a P/P system in a Right Access Silverstone cabinet. lol
