About the Product
Built on the basis of the legendary NH-D14 and carrying on its quest for ultimate quiet cooling performance, Noctua’s flagship model NH-D15 is an elite-class dual tower cooler for the highest demands. Its expanded heatpipe layout and two premium grade NF-A15 140mm fans with PWM support for automatic speed control allow it to further improve the NH-D14’s award-winning efficiency. Topped off with the trusted, pro-grade SecuFirm2™ multi-socket mounting system and Noctua’s proven NT-H1 thermal compound, the NH-D15 forms a complete premium quality solution that represents a deluxe choice for overclockers and silent-enthusiasts alike.
The V8 GTS is the latest addition to Cooler Master's popular V-Series high performance CPU coolers. V8 GTS sports a newly designed, powerful car engine look. Cooler Master's new high performance horizontal vapor chamber technology found inside the V8 GTS spreads heat up to 8x faster than traditional heat pipes, minimizing CPU hotspots and quickly balances the heat load between all heat pipes. The combination of the horizontal vapor chamber, 8 heat pipes, and aluminum fins allow the V8 GTS to display extremely high efficiency and cooling performance.

What customers say about "Key Specs"
Noctua NH-D15 6-heatpipe CPU Fans
  • If you're not going with water cooling this is your best choice. This product beats out most of the entry level water cooling options and performs really close to the top end ones.
  • Keeps CPU extremely cool.
  • I'm actually a bit surprised but Noctua has convinced me. I don't often use Air coolers for builds anymore but if and when I need to I know that Noctua does make high performing products.
  • Best, most effective air-cooled heat sink I've ever owned. Don't even need the second fan that's included, I'm under 60 degrees C at full load at my max overclock.
  • With good airflow, this will allow you to overclock without worrying about cooling.
Cooler Master V8 GTS High Performance CPU Cooler
  • It keeps my System at 24c when gaming. I really do like this Megatron Head cooler. It keeps it cool WOW, I'm running a MSI 990FXA-GD80 that had a Cool Master and it keep it at about 32c, Then is stopped performing.
  • No longer need to leave my window open in winter to keep my PC cool.
  • This beast is insane! After my pump in my custom water loop almost blew up, I decided to switch to air cooling. Me being an extreme person saw this and said "I must have it!" So I bought it.
  • Does a great job on cooling efficiency. Stable 32C. Never breaks 35C under load.
  • When gaming (with CPU intensive games) the temperatures are 45 degrees centigrade. This is a massive improvement from my low grade Deepcool FROSTWIN v2.0 where I would need to underclock the CPU to 2.5 to have the temperatures at 54 degrees centigrade

What customers say about "Size & Weight"
Noctua NH-D15 6-heatpipe CPU Fans
  • Installation is easy considering the size.
  • It does a nice job of cooling but it's huge. It blocks access to the memory modules on my motherboard.
  • Be prepared for the size of it and make sure it will fit in your case.
  • Only major complain is the size it's huge and a pain to put on and still interferes with ram space.
  • Be careful with the size of this monster. It is HUGE. If you have a large computer case, this shouldn't be a problem at all. The size of the cooler helps with its performance.
  • The heatsink has some decent weight to it, and it is big. Putting it one was a bit tricky because of it's size.
Cooler Master V8 GTS High Performance CPU Cooler
  • The Cooler Master V8 GTS's unique design allows the heatsink placement to blow air out of the top of the case.
  • Covers up the top PCI-E slot on Z375 Godlike. Can be difficult to start mounting nuts due to headers.
  • Very very large (Can be a pro, depending on your chassis. My In-Win GT1 with clear window barely was able to close. It presses on the V8 a bit, and the V8 needed to be mounted sideways to even get close to fitting.)
  • Only downside is that it is massive and was 3 centimeters too long for my inwin 905 case, so I have to get a new, but I needed a new case anyway, so no real issue there.
  • On the large size, height wise, suggest adding to the description you need at least a 8" wide case

What customers say about "Features"
Noctua NH-D15 6-heatpipe CPU Fans
  • Even at 100% fan speed, they are not very loud.
  • Slightly puzzled by the inclusion of the speed reduction adapters, as even at full speed, these fans are completely silent.
  • This fan is quieter at full speed than my stock CPU cooler was at it's slowest.
  • It's about the same as the noise floor in a normal room.
  • A long way from the scary temperatures I was getting prior to the new cooler. I cant imagine this cooler getting hot ever!
  • I removed two stars because of sound; namely the very annoying high pitched whining sound that one of the fans made. I ended up replacing the one fan that came stock with this cooler simply because I couldn't stand the sound.
Cooler Master V8 GTS High Performance CPU Cooler
  • Comes with perfect amount of thermal paste
  • It looks amazing when installed. When you see it through the window you expect it to rev up like a car engine. The noise is moderate but not noticeable when you don't focus on it. Overall good build quality with minor quirks.
  • Very VERY difficult to clean, if your case has a dust problem. Canned air just doesn't shine it up like new. It requires disassembly for proper "back to new" cleaning.
  • Noisy. A high pitched noise alternates between high-low frequency constantly.
  • The manual is horrendous. There is literally no way to make sense of the instructions if you're a person who likes to according to the book, or manual.
