After 2 weeks I'm still looking for a lightweight cooler for a computer I will be moving around often and found the Scythe Shuriken 2. There's plenty of comparisons to stock available for the Noctua NH-l91 which I had been looking at but unfortunately that cooler seems to perform kind of badly. No back plate either which is a no go. I want as little stress on the board as possible. The Shuriken looks good as far as physical specs, but there's scant info on how it compares in performance to stock, only to other coolers. I'm not overclocking or anything, I just want reasonably cool temps and low noise.
