a Lucifer in dual fan ... and you need a better CPU cooler? well only a water loop will do if so ... because Lucifer/HR 02macho/and other huge ass heatsink with awesome price for the performance delivered, are not really inferior to any Silver Arrow/NDH15/ and other huge heatsink with a horrible price for the performance delivered.
and by waterloop i don't mean a AIO even a 280 or 360 is nothing compared to a custom loop 240 (well ... maybe Fractal Kelvin serie, CM Nepton, or swiftech ... would do)
my 4690K clock at the same range (with no voltage added too ... just multi and nothing else xD ) actually at 4389 on 1.224v (i lowered the OC to find if it was the culprit on a CTD problem )
also i shall use that post as a placeholder for tomorrow delivery (hopefully)
PS: i have the same octopus on the back of my AIR 540 ...
