Summary: My first build, cooler is running 26 degrees idle and after 4hrs of gaming i was only at 38 degrees. Definetly need a bigger case for this fan, im using an old antec 900 series mid tower , no problems there. Fit my old lga 775 socket fine.
Summary: Almost all reviews of cooling solutions come to the same conclusion. The Hyper 212 EVO is the most cost-effective solution for your CPU. I use it with an over-clocked I7 3770K and I couldn't be happier. In most cases you will have to remove the motherboard to install the backplate. I had to even though my Cooler Master Scout has a cut-out for the backplane. It didn't allow sufficient clearance for two of the screw holes on my ASUS p68 mother board.
Summary: I used this with a Sabertooth X79 mobo and an intel i7-3820 overclocked to 4.6 ghz. It was able to keep the CPU under 45 degrees during the 100% stress test program that Asus provided with the motherboard. I used the spreading method (thin coat over entire CPU) with Arctic Silver 5 High-Density compound thermal paste.
Summary: It's huge - but for a reason. I don't overclock but I do use my system for heavy video rendering and editing. NEVER have had an issue with heat - even when the room temp was high. You may have to check clearances with your RAM before purchase.
Summary: I just built a new computer and I have to say this is the single piece I'm the most pleased with. It's not over priced and worth every penny. Keeps cool even though I'm overclocked 1ghz and it's very quiet compared to the stock fan.
Summary: Put this heat sink and fan in my machine over a year ago and it has never failed me. Like all components in your case it will collect dust on the massive heatsink, I recommend taking it out and dusting it out with some air every 3 months or so. Great performance for the value.
Summary: This heatsink and fan worked great out of the box. The instructions were fairly easy to follow. You should install it before attaching MB to case. It keeps my new i7-3770k nice and cool(61C) at stock levels while playing BF3 at full rendering.
