Which direction is intake or exauhst?

[aidenjmccomiskey]

Hello, I have the Corsair H150i pro and I can't tell which direction to put the fans on the radiator. How can I tell which direction the intake side is?

P.S. I used the included fans (ML120 )

You mean as for a fan intake/exhaust side? That's simple, if you see the whole blade then you're looking at intake side, while when you see the fan frame which holds the fan hub in place, that's exhaust.

E.g, in this pic, you see fan intake side and fans are pushing air through the rad,

For a rad, there is no difference on which side or which way you mount the fans. Though, i'd mount rad fans in pull.

Perfect video, being trying to explain the 'dirt donut' for years lol.

The only exception is a vanity/aesthetics setup with ppl using RGB or other lighted fans. Generally most lighted designs have little to no rear facing lighting, it's mostly towards the front/visible area, making push an almost guarantee.
