Are you planning to overclock or run at stock speeds? slight overclock
What country are you in? Australia
What is your budget? no more than $400
Are you worried about aesthetics for the cooler or only performance? not too worried about aesthetics as long as it works well
Are you doing this just to upgrade or was there a problem with the previous cooler? i have a wraith cooler but it just tends to get a bit hot from time-to-time
If there was a lack of cooling performance and that is why you are wanting to upgrade your cooler, what is your case model and how many fans are installed? What size are they? Where are they installed and are they intake or exhaust fans?
Im upgrading to a Cougar Panzer and im just looking for a bit more of an upgrade cooling wise, i have brought 7 new fans so case flow shouldnt be a problem
