Summary: I have a ASUS MAXIMUS VI HERO LGA 1150 Intel Z87, with G.SKILL Ripjaws X Series ram. The bottom fan would come into contact with the ram so I was forced to remove it. This might not be an issue if you have low profile ram, or on certain mobo's. Make sure you have enough room between the cpu and the ram slots before purchasing. I also had a very difficult time installing, as the heatsink significantly overlapse with the mounting screws to the mounting bracket.
Pros: Extremely efficient Quiet under load Blows air directly onto the mobo Sturdy and well built
Cons: Large Pain to install and unistall When seated bottom fan touches ram
Summary: As a home computing enthusiast, I've used a few big honking PC coolers before, such as an old Arctic Cooler Freezer Pro model. However, having shelled out the extra dosh for this Noctua model, I don't see any reason to ever go back again. This heat sink is a real Cadillac among coolers, right down to the glorious heat pipe arrangement that made me halfway apprehensive as to whether I should put this in my computer or display it in a car showroom.
Summary: I have a mini ITX motherboard, which is pretty small, and although this cooler is rated to fir on mini ITX boards, I found it too heavy and cover up too much of the motherboard. I'd say use a cooler of this size on a micro ATX or larger motherboard.
Pros: Noctua build quality. 2 high performance and fairly quiet fans for push pull setup on this cooler. Speed adjustments with cable attachment or software controlled. Quality mounting hardware.
Summary: I loved its cooling capabilities, got it on lowest RPM with supplied cables, but faced a problem as I can't install my graphic card on PCIE 1 and had to use PCIE 3 as the first was too high and the card will have contact all the time with the Noctua. It was my fault, hopefully will learn from it, but for a SILENT build (using quite fans of 1,400 and 1,000 RPM for case and the case is Define Mini), its fantastic for cooling the CPU and the other components around it,...
Summary: It doesn't seem to matter whether the fans blow away from the CP (logical: move heat the way it wants to go anyway) or at the CP (their unexplained recommendation). If you choose to have it blow away from the chip, you'll have to re-site the bails to the other edge and rotate them 90 degrees, which is easier to do than to think about. I used their paste (supplied) but I suspect it might be less effective than it should be.
Pros: It seems to keep a Phenom II x6 1045T (95W, not o/c'd) fairly cool when the CP load is about 50%. Not cold (which I expected) but cool according to CPID HW Mon . It comes with 2 different speed- and noise-reducing resistor options. I chose to leave them out and run at full speed. It's easier to install than it seems: just don't fit the fans til after the frame is in place and dogged down. The wire bails make clamping and unclamping the fans to/from the fins very strai...
Cons: From hard-won experience, I prefer to keep everything in the case not merely cool but *cold*, if I can. I thought that on humid days this fan should begin to cause frost to form, but not so. That puzzles me and I wonder whether there's less to these oversize sinks and fans than meets the eye. I'll probably experiment when I get some time, unless someone else beats me to it. I'm not sure whether this is a real con: it *did* fit in my huge server/workstation case with 1...
Summary: First off the cooler itself is great no problems there. Got my 3770k to 4.5 and it only 52C. I am running both fans off chassis header because they are voltage controlled and at low rpm u can feel a small vibration. if u gave tall memory you may run into clearance issues if you use the bottom fan.
Pros: awesome cooler
Cons: no pulse control fans out of balance at low rpm
Summary: Take the motherboard compatibility with a grain of salt ;-) I love the metal decal for the front of my case
Pros: Excellent drop in cpu temp. Very, very quiet. Lots of extras in package!
Cons: Not a great fit with an MSI z68ma-ed55. Noctua website lists it as compatible but you will have to order memory sticks with low profile heat spreaders. Also, you have to rotate with heat pipes facing the PCI slot. And there's only a couple millimeters clearance to the back of the video card. I wrapped some electrical tape around the head pipes so they wouldn't short out my video card if my case gets bumped.
