    Default Newbie Fan size help please

    I have an 80x80x180cm tent and a vividled 150watt quantum board can anyone recommend a silent extraction fan and filter and intake fan setup. The ducting would be roughly 80inch long and would have 2 bends. Cheers

    A 4" RVK & Rhino should do the trick... but a 5" with a fan controller may be quieter... see what others think as I'm not really up on LED heat

    agree with M_C, the 4" extraction, minus 25% after the Carbon Filter is added will give you around 138 m3/h when, given your tent size, you're needing 130 m3/h including your filter and duct bends as a minimum.

    These boards can run hot (is it adjustable wattage?) and I'd be looking at a 5" rvk (220 m3/h -25% with filter = 165 m3/h) as a minimum (growing in Summer?) or even better, a 5" L1 rvk (323 m3/h - 25% with filter = 242 m3/h) on a speed controller which should give adequate cooling while reducing noise a good bit and allow all year 'round growing.

    For intake, I'd setup a 4" rvk, and use with the 5" extraction, as and when required or just passive intake (ie: no intake fan) in the cooler months.

    cheers
