Not cheap but great products

Best on the market.

Very quiet and easy to install. Temps are low on full load but I have not done any overlocking yet.

Make it sure it fits with your RAM as it may be too big so you only can use one fan. Comes well packaged and super easy to set up

Good fan though though

cracking bit of kit, but make sure you got the case space to handle this thing, i mean its approx a stick of ram cubed! you will likely want low profile ram sticks if you intend to stick both the fans onto this beast!

Works really well even without the additional fan

Having not built a PC for many years I was clueless how the new socket types work. ZIF sockets were barely a thing last time I built a PC so you still had to crowbar the cooler onto the CPU. When I opened this cooler I was very surprised and more than a little intimidated by its size and the process of installing it, but the instructions were pretty good and I got it installed with a minimum of stress. I use this in a recording studio and the cooler is basically silent. The CPU fan very rarely kicks in and when it does you only know by looking at it. One thing to note is that you have to be careful of the orientation of the cooler if you want a GPU in the top PCI-e slot as the cooler is not square and will block the top slot if it is oriented so it is taller than it is wide. I was sceptical about the price of this cooler but I bought it because it was recommended. The cost is more than justified, this thing is a work of art.

awesome, just awesome

One of the best coolers you can buy the only downside is colour.

Keeps my i7 cool and It is very quiet

This is the second PC i've built with the NH-D15 Dual Fan, Dual Radiator arrangement. If you're thinking about getting this, you won't regret it. The Best Cooler around, and so easy to fit. Comes with excellent Heatsink Compound too. Just remember to check the Cooler will fit your case. Mine is the Corsair 450D Obsidian.

This is arguably the best *air* CPU cooler you can buy. It is pretty big with the 140mm fans, but in return, you get a much quiet cooler. I easily overclocked my 3.3GHz spec cpu to 4.5GHz using this cooler without trying too hard.. Alright, my i5-2500k might have been a "good un" but the previous aftermarket Corsair only managed 4GHz overclock. People complained about the colour, but come-on guys, this is ridiculous fashion consciousness.Your fellow geeks might be aware of the latest in colour trends, but no-one else care sweet FA about the colour of your cooler fans!

Simply the best air cooler you can buy, if it fits in your case. Superb cooling and quality, you get what you pay for.

Super quiet, easy to understand instructions. Best air cooler around.

Best air cooler on the market - I've got a 9900k running at 5.1GHz all cores, and under load it barely hits 70C. During normal use on my audio workstation, it's effectively silent. It is expensive for air cooling, but it matches/outperforms AIOs that cost more, so it's still decent value long term.

It is a good, reliable fan. There are minor noises when starting up, but that might be just the case of a dodgy installation.
