Its low-profile design made it feel like a smart choice for small cases.
Why I Considered It
I considered this cooler because I wanted something that could fit in tighter spaces while still handling modern CPUs reasonably well. For me, the Big Shuriken 3 Rev. B made sense if I was building a Mini-ITX or slim desktop system. I liked that it offered a balance between size, compatibility, and cooling performance.
Design and Build Quality
I found the build quality to be solid and thoughtfully engineered. The fin stack layout and offset fan design help it avoid interference with memory modules and motherboard components. My impression was that Scythe focused on making it both compact and efficient, which is exactly what I would want in a low-profile cooler.
Cooling Performance
From my perspective, the cooling performance is good for its size, but I would not expect it to compete with large tower coolers. I see it as best suited for low to moderate heat output CPUs. If I were using a high-performance processor, I would make sure my workload and case airflow were compatible with a low-profile solution like this.
Noise Levels
One thing I would pay attention to is noise. In my experience, slim coolers can become more noticeable under load, and this one is no exception if the CPU gets hot. Still, I think it is reasonable for everyday use, especially if I tune fan curves carefully and do not push the system too hard.

- A cleaner motherboard layout
- Cooling for efficient or mid-range CPUs
I would not choose it if I needed maximum thermal headroom for heavy overclocking or a very power-hungry processor.
What I Would Check Before Buying
Before I bought it, I would make sure:
- My case supports the cooler height
- My CPU does not run excessively hot
- My RAM and motherboard layout leave enough space
- I am comfortable with a low-profile cooling solution
