Summary: tests on other websites show that there is little difference between running 2 fans and using only the top fan (bottom fan only shows a more significant difference). so, if you have RAM with top fins, its not a big deal to remove the bottom fan (which has the added benefit of being somewhat quieter). Alternatively, you could remove the fins from the RAM, if allowed (such as on Trident-X RAM) and get extra RAM cooling from the fan blowing over it.
Pros: •this is a great alternative to the D14. while the performance isn't quite as good, it is one of the best if you clearance issues with the tower style HSF (in my case, the GPU placement on my motherboard is the limiting factor for tower style units) •as expected, great Noctua quality •comes with Noctua's thermal compound (only a quarter tube though), which is one of the best on the market •good, easy to install, mounting hardware
Cons: •Noctua fans are not pretty, and it is very visible through the side window of my case •included fans aren't PWM
Summary: Over all I would suggest any buyer looking to get a decent heat sink to STAY AWAY from this ugly piece of junk. Not worth the money spent on it and you surely are better off with a stock CPU heat sink or possibly anything else. And if all else the level of noise that comes from it will surely drive you insane.
Pros: The cooling works.
Cons: There's a lot of cons with this heat sink -Huge pain to install, definitively have never had this much trouble and frustration installing a heat sink. Instructions were not clear and I had to find a video just to realize that there were tiny holes in the heat sink to get to the screws. -This thing keeps my CPU about as cool as the stock CPU fan that came with my processor did. -It is overall a hideous piece of equipment, I bought this because of the price and since th...
Summary: This thing just reeks "old." The fins are not reinforced in any way like modern Phanteks, Cryorig or even current Noctuas. Therefore they are super easy to bend. The fans are ancient 3 pin P14's and the entire accessory package has remained the same since 2011. This heatsink performs like a $25 Hyper 212 but at 130mm height.
Pros: -Great packaging and accessories. -Straight forward and simple installation. -NF-P14's are quiet
Cons: -Honestly this is a really outdated Heatsink, many single fan and even slim single fan solutions offer the same performance. -Uses the older Secufirm mounting system instead of the updated one. -Uses the old style splitters and noise adapters that have exposed wire and aren't fully sleeved. -The support bracket that was later added is laughable. -Fans are not PWM, at this price makes no sense.
Pros: Very silent, very efficient, directs its airflow toward the motherboard, providing additional cooling for motherboard mounted elements (chipset, memory etc.) Used with Rosewill BLACKHAWK case, Intel Core i7-4770K and GIGABYTE GA-Z87X-D3H. Can be used with one or two fans.
Cons: I would think how to fix fan cables. This is not a problem but it requires to fill "Cons".
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: I bought an Avatar gaming PC with an AMD 8-core FX processor. The stock fan setup was barely keeping it within safe operating temperatures (it was bumping 70 degrees C very frequently).. I think this is possibly due to somebody adding too much thermal compound when they installed the heatsink. It was gooping out all around the processor and the processor was glued to the stock heatsink. It took considerable force to pry them apart.
Pros: This thing is great! it is very quite and it dropped my CPU temps significantly.
Cons: The only con is that it is ginormous! You should probably verify that it will fit in your case before installing. Also, if you have a large heatsink on your RAM modules, you will either have to remove the RAM heatsink or the bottom fan from the Noctua. One nice thing is that if you do have to remove one of the fans from the Noctua, there is an option to mount it as a case fan.
Summary: This thing is a beast, in a very good way. Seems like a bit of a monster, but it installs solidly and is a serious cooler. I previously had the side-by-side version of the noctua cooler, but I like this stacked version a little better, though mainly for looks. It probably performs about the same, but I do like the idea that it blows down onto the chip and motherboard, and it also looks great from the case window. Overall very nice, and tough to beat.
Summary: And that is a ridiculously overbuilt product with visually evident meticulous quality control that performs absolutely perfectly. Even the packaging is top notch. Just mind the specs, because it's bigger than you would expect going by the pictures. As for performance: it easily handled an old, mildly overclocked Bulldozer arch processor that previously ran excessively hot on the stock cooler on stock clock speeds.
Summary: My case just is too lame to fit this much awesomeness. PCPartPicker said it didn't fit but I wanted to find out for myself, out $10 return shipping but damn was it worth it. The level of quality was amazing. Makes me want to get rid of my custom loop for some Noctua. Best mounting system I've come across. Best packaging I've come across too. If it fits your case, get it now!
