Yeh nice list indeed but thinking of ordering the H70 or H50 but its expensive so i am still looking for alternatives.
I have a Coolermaster Hyper N620 which is not expensive, quite decent, and more than good for my moderate OC needs (i7 920 OC by 25%). In India, the availability of all brands is not great and one has to pick the best out of what is available.
Thermalright Silver Arrow, when you also take noise and price into consideration. Even with its excellent results apparently the base isn't completely flat and even better results can be gained if lapped...
I'm using a CoolerMaster V8 and it's awesome. Also, the CoolermasterV6 is a good choice. My V8 is very quiet and cools even in OC......my temps never go over 45c in normal use and under 70c in OC........ I'm also thinking of changing the supplied fan with a Noctua 120...better CFM and even quieter.
IMHO you can also opt for a Noctua NH-D14. been reading alot of revieuws and ,especially for BIG tower coolers, the NH-D14 seems to be one of those with enough ram clearance(by adjusting the Fan a bit) the silver arrow doesn't have that much (configurable) ram clearance.
I've bought a Scythe Ninja 3 some weeks ago. 31€, 110 max cfm, easy regulated & very quiet. You can use even without fan. You just pay atention to your computer case size.You need a big one.
It depends on how muchyou heat your PC .If you are a hardcore gamer then you would need a strong cooling system .
I'm going for the Corsair Hydro H80 in my new setup . If you can pay that little bit extra you are getting a cooler that punches above its weight. More than capable of cooling an i7 2600k oc'd to 4.7ghz.
In general my system is making 45 degrees. but the stock fan is making to damn much noise. i also got 1 fan for the front intake and HDD's. and 1 fan in the back. all controlled by a fan controller. i am thinking of getting the h80 like alextheg mentioned..
I have the Coolermaster Hyper N620 which is OK-enough for me considering that I do not overclock the i7-920 much (20% overclocking), and ambient temps are manageable. Summer peak of 110F/45C and winter low of 32-35F/1-2C. It is compatible with LGA1366, was supposed to be compatible with LGA1155, and hopefully will be for SB-E too.
as for the zalman cnps 9900, good cooler, but it's a noisy one, was considering one of those, but after a lot of research my next cooler still will be the d14, best performance and the quietest corsair hydro H100 seems to do a pretty good job too, but then again, aio,factory pre-filled watercooling, could go wrong in some instances, leakage has been reported numerous times on it's predecessors
