Well, if you're looking for the same price range ....... than according to the post Thermalright IFX-14 BP should do just fine...... I personally feel it's a better performer and lighter in weight, plus easier to clean..... and plus theres a variety of fans to choose from..... and it will certainly fit into the Stacker
But the price difference between the mugen 2 and the IFX-14 is like $45 for not that much of a difference plus the Scythe comes with a fan already with it.
Well I went with the Mugen 2 and am pretty stoked, dropped my idol temps from 33 to 28 Celcius. Haven't tested under load yet and haven't OCed yet but thats next goal
Ireally can't tell you much about the pricing since I have found them at nearly the same rates from various sites........newegg,shopbot.etc try a few and see what you find.......
Newegg does in fact list the Mugen 2 and at a reasonable price. listed for 36.99 U.S. Dollars at NeweggScythe Mugen 2 http://www.quietpc.com
Price: £43
Thermalright IFX-14 BP CPU Cooler Our Price: $74.99 with fan
Looking at the varying prices all over I have a feeling you'll get the best hopefully at the best price out there...... just take your time and don't be in too much of a haste...... lotsa good stuff coming out there and Christmas ain't too far..... happy chilling
