Fans on radiator.

Havent checked the bottom links but yes,
That rad is for 140mm fans, your selected fans are the correct size, and once you get the rad you will see the screwholes, screw through the fan to affix to rad :-)

Sorry, my question is, how do you mount a fan on a radiator.

Thanks!

Dont go those, its a very bad idea. best possible combo is black ice 120mm with 3 gentletyphoons from schyte (if you can get them). I recomend the 1850 rpm model for performance and the 1450 for silence.

The reason is that those fans, apart from beeing quiet and moving a good ammount of air, also have very good static pressure, wich is key when you are using a radiator as your cooling main object.

It will cool down both the parts you show, but it will depend a lot on other parts as well how well it actually will.

If you get a good pump, and decent waterblocks, you will be able to overclock both decently. Just be carefull with the gpu, it dumps a huge ammount of heat to the water, and you should use a "full cover" waterblock.
