Push/Pull Radiator Discussion

Go to solution Solved by Salticid,

Agree with Benjeh.  Further, I haven't even seen it or tested it in practice, but in theory the difference in pressure generated by the static pressure fans paired with non-static pressure fans on the other side of a push-pull could potentially cause stress and greater wear on both sets of fans, causing even more headaches and potential early failure.  They would essentially be fighting each other, causing more resistance instead of complimenting to help mitigate resistance - resistance you don't have so have no need to mitigate, as well.  That you're even asking shows you have a nagging sense that something is potentially wrong with this configuration.  Trust your instincts on that.

 

I get not wanting to waste equipment you have, especially if you feel you have negative space to fill.  My case came with fans I like the look of but just can't use too.  It is what it is.  Just because it came with doesn't mean you have to use it.  It's a bad idea to create a configuration that likely will cause more problems than it will solve and thus require a disassembly early on to correct it, just to fill some space you're not sure what to do with yet and use product you happen to have on hand but don't need.

 

Live with the negative space for a while, why force clutter.  It can only help your airflow, and maybe it will grow on you.  If you decide you really don't like it,  sell the extra fans to someone who can use them and use the money for something neat to fill up that extra space.  By that time, you may have thought of something really cool you'd like to have, or add to it.

 

Or hold on to them and maybe in an upgrade or another build you do in the future you find a use for them.

I want to setup my radiator with a push pull setup with RGB fans (maybe the corsair ml140?) on the internal side of the case (visible RGB on the inside of the case), and my current Be-quiet fans on the outer side of the case (exterior facing).

 

I don't think this would cause any real issues, aside from having RGB (for those of us that despise it). The question being, can using different speed/pressure design fans create excess noise or virbration or work against each other in some way if i use them in that setup?

 

Im using the Dark Base Pro 900, and would have 2 radiators in push/pull (140mm fans)

Do it and find out. I never used mismatched fans so I can’t say. I buy the same stuff.

I'm looking at a 4 or 5mm thick one, the push/pull is more of an aesthetic because I have a lot of room. I just don't know if having 2 different RPM fans will create vibration/excess noise or not.

Don't use fans with different stats, you're just going to cause headaches, just put the RGB fans in pull config, honestly RGB has been the worrst thing to happen to the PC scene than fortnite can ever be...

Well the other fact is the Be Quiet fans came with my case, and I don't want to just not use them,  (Like i said I have the room). I doubt I would run into issues, putting it out there in case someone else has, and can give guidance

I'm trying to learn what those headaches are to see if they are worth it or not. I want to take advantage of all the hardware I have instead of just putting the extra fans in a box and forgetting about them.

the slower fans will probably get forced to spin faster than they should due to the faster fans, they difference in blade designs will probably reduce effectiveness and may cause more noise. Personally I wouldn't use push pull and a rad unless it had high FPI and i wanted less noise or an extremely thick rad (im talking 80mm thick).

@Salticid I ended up doing 'push' configurations on both radiators. I don't have a use for my original fans right now, but I can always use them somewhere else. 

 

I know enough that increased vibrations can be cause by a-synchronized repetitive actions, ie, fans spinning at different RPM, different speed HDDs in close proximity (but im not using any of those in this build), etc. For all anyone seems to know, this could just be so minor it doesn't matter in a pc, but its not worth the potential, shorter life span, potential noise, for such small return.

 

Thanks everyone for the input, been away awhile.
