Depends on how you define "compatible."
Will they switch on and off/change fan speed if you replace the white LEDs with them? No idea, chance they might not. Will they fit in any 120mm mounting holes in the Stryker's casing? absolutely.
Whoops sorry yea I know they'll fit LOL should have been more specific. I guess just wondering if they're even switch on and off and if the fan speed might work on the case for those fans by chance? Any clue if the NZXT Sentry LX Fan Controller will function well with them (as far as fan speed control that is)?
