    • Perfect fan for a RAZER fan

Super bright and clean glow. Looks perfect in my razer case.

    • My buddy says it's good.
Size: 120MM Style: 1 Fan Configuration: Fan
This was a gift for my bud but he said it's one of the best ones he's owned and he is a technophile that changes PC setups basically every month and he says he will keep this one so I'm assuming he really likes it and if my buddy likes it I do too.

    • Great construction, great colors, premium price
Size: 120MM Style: 1 Fan Configuration: Fan
They're overpriced, but if you can get them on sale, they're worth it. The quality of the construction is top notch. They don't use proprietary cables, so you can use them with most common devices. Each fan has an ARGB daisy-chain cord, which is nice. But what I like best are the COLORS! The colors produced by the LEDs in this fan are incredibly true to life. Look up any hex color code, make the fan produce it, and it matches exactly. I can't say how impressed I am with the colors on these fans, as compared to cheaper $10 fans. Everyone says it's hard to produce a true white (#FFFFFF) light from RGB fans, but on these Kunai fans, it's easy. They produce a perfect white light when set to #FFFFFF, without the blue tint that cheaper fans produce. ... show more

I've been building PCs for years and these Kunai fans outperform every other fan i've used, they are super quiet! Easy setup and I love how the chroma looks with the rest of my Razer setup!

    • Support is not helpful
Size: 140MM Style: 1 Fan Configuration: Fan
My product came without a serial number. I can’t register the product and razer support is not helpful so far because they ask for mor a serial number to create a case. Make sure you check your box for a serial number before installing. Will save you the 2-3 hours I spent taking my fan out to replace this one and set up my computer only for it not to be able to be registered. Fan works fine as I can tell but I can’t access any of the rgbs or speed due to no S/N! Update: apparently there are no serial numbers for this product. I still don’t know how to connect it to synapse but your motherboard must have a ****3pin a-rgb**** are to match your case/mb lights ... show more
