The Kotetsu was tailored for the PC user on tighter budget in that It has four heatpipes, for fresh air a 120mm GlideStream PWM is equipped - for the heat dissipation level of the new Haswell processors this combination is more than efficient and cooling performance will not disappoint.

Who is this heatsink for? 6/5/2019 8:57:31 AM

Pros: The aesthetic of the heatsink itself are rather nice. It has a nice clean smooth mounting surface to sit on your CPU.

Cons: The fins are frail and too easily bent. The temps I'm getting at idle and at full load pale in comparison to a Zalman Cool & quiet all copper heatsink I bought four or five years ago. I've tried many combinations of thermal paste, and still am not getting the temperatures I want, the fan is quiet, but that's not exactly an issue I need help with.

Overall Review: The "official" fan clips are a joke, they have to curve through the notches in the 120mm fan in order to clip tightly enough to the heat sink. They feel flimsy and are difficult to place onto the heat sink itself. You absolutely have to mount the heat sink first before you can clip the fan onto it, meaning it may not always be adjacent or exactly flush with the heat sink fins. I've used quality thermal paste, in differing amounts, but never too much or too little and am failing to see any temperature improvement on a stock speed i7-4790k. I'm not happy with these temps, often I'll see them as high as 58 degrees centigrade on load, or higher depending on the game. Compare this to 40 to 45 degrees centigrade on my ancient Zalman heatsink and the difference is quite severe. The fan speed is set automatically in my bios, so I might try to keep it running at full speed all the time, but then again why would I want that trade-off if its supposed to be a quiet fan?

Worked better than expected! 1/5/2019 9:49:35 PM

Pros: Very quiet and keeps my i5-6600k 19-20C at idle and in the low 30s C during full load. Using only the 1 Scythe fan. In a Fractal Design R4 case.

Cons: Metal Fan Clips are kind of a pain to use but they work.

Overall Review: Went off recommendation from for a quiet and capable cooler. 2.5 years later and this thing is still working flawlessly. Coming from a CM Hyper 212 it is a step up. Great air cooler.

Top performance 8/21/2015 9:53:26 PM

Pros: Like the review on, the Kotetsu has performed astonishingly well.

My temps float around the low 30's Celcius, and at load approach the low 50s celcius.

This is sitting in a Fractal R5 with a push-pull fan configuration (in addition to the included CPU fan).

Assembly rig felt solid and weight feels right for the unit.

I am replacing the metal fan clamp with rubber type clips to lessen vibration against the heatsink.

Cons: None so far.
