Hey guys, just a quick question, I have 2 spare 140mm fans that I could use on my 280mm radiator, atm there are two stock fans that came with the cooler, these run at 1400rpm roughly, the fans I want to put on (push pull config) to sandwich the rad only operate at around 900-1000 rpm, does this have any effect on the performance of the cooling system etc?

 

Cheers

Might have a more positive impact, pretty sure you can sandwich the radiator, I guess have one pair push and the other pull.

Push/Pull will not yield any difference, maybe 1-2°C...

At lower rpm is where it makes bigger differences when one set of fans has trouble pushing I through. In my experience at least.

That can be true I guess... On my Kraken X61 I am idling at 28°C and that is with a radiator close to my PC :) and I am on push only... RPMs are not a concern, CAM sofware regulates them depending on temps

 

On full load while Folding@home I am at 60°C and still barely can I hear the fans. Stock clock on CPU btw

In this situation specifically, just to clarify

 

(going push/pull on my 80mm thick rads helped much more than just push)

Push-pull will only yield significant benefits on really thick radiators (eg Alphacool Nexxus Monsta) or when using fans that are airflow optimized vs optimized for static pressure. That being said I'd say add them if you have them lying around and see if you get any benefits and evaluate the effects yourself. Do remember that adding more fans will probably significantly raise the noise level of your system.

Were do I buy sleeved cables? That would be awesome!

 

 

Icemodz.com is a good place to start, he can basically do anything you need.  He did the cables in my build. Super nice guy too.

I see you have an RM750 :) I have the RM850 so you would need the same as I have :) but be warned, it is not cheap... 100 dollars for the whole set

You could get extension cables, they are cheaper, but that just means more cable clutter to manage
