Corsair H100 Push/Pull question

post #1 of 8
Thread Starter 
If I want to run a P/P setup, do the fans have to be the same? For example, I have 2 scythe ultra kaze 3000rpm as pull. Would I be able to use the corsair stock fans for push?

If the fans are not the same, then they will be kinda 'bottlenecked' by the inferior fans. Also in the long term it will damage the bearings and the fan itself.

How would it damage the fans?

As the fans will be pulling the blades into the radiator, and the extra force will cause the bearings to eventually get some damage

Wrong. That's not why it causes damage.

having two different sets of fans will cause damage because the more powerful pair can accelerate the blades on the less powerful pair, causing it to quick faster than it should, prematurely burning out the motor.

It does happen in some cases though, I have seen one on the Corsair forums where they installed some high speed/High CFM fans on with the orginal ones, and after a while the bearings broke and it caused very extreme rattling

What if they were used in pairs. Like for example:
Scythe-Rad-Scythe
Stock-Rad-Stock

Where rad is of course the radiators, and the matching fans are placed together. Wouldn't have solve it, except for the differing performance?

I thought about that. There's just residual pressure bleed. But eh. Honestly I'd just do it, the only fans you would burn out are the stock ones so who cares
