I need advice from more experienced users to choose good fans for watercooling loop

Good evening everyone

I have started to make my loop in Corsair Obsidian 900D, and I'm pretty sure I'm gonna use those fans (120mm), cos they're the best:

and make push-pull on the bottom of my case with:

I'm not sure about top. I'd like to use same radiator, eventually them:

http://www.watercoolinguk.co.uk/p/Alphacool-NexXxoS-XT45-Full-Copper-X-Flow-480mm_58286.html

but space between mainboard and top radiator already installed will be very limited to create push- pull
Is it good to use one thinner radiator and make push pull or just better to install one like this:
http://www.watercoolinguk.co.uk/p/Black-Ice-Nemesis-GTX-480-Radiator-Black_44940.html.
and make only push with noctua fans?
Also one more question if I may.
Is that pump and reservoir:

is enough to make good waterflow and cool down I7 5960X+gtx1080?

Thanks for any help, tips and good advise.

Don't think your supposed to list other shops here

Push / Pull is a waste of time, unless you like the look, just get whatever fan you fancy, check the fan specs, they are not totally accurate but give an idea.

I listed other shops with no particular reason to make them new shoppers, but I wanted anyone reading that thread just to see my components if they're ok or not.
I like Noctua, even if they do not have that flashy lights they're much better than any other fans.
I'm just confused if I create push pull with two sets of them on the bottom of radiator and on the top they're gonna kill each other or blow the radiator away!

You're listing competitors. Your post will be pulled so find another way of listing your component choices.

I think fans are very similar really, they're all the same shape, how different can they be?

Choose based on RPM, looking at size of rads you're going for there'll be plenty of cooling with some low RPM fans

I believe that's THE pump to buy right now so yes go for that one.

I don't think you need push-pull, certainly not on rads where the noise is going to cause a problem, for example : top mounted rad with fans between it and the top of the case is going to cause noise. I would have top of case>rad>fans pulling air upwards and out through rad/top of case.

The forum rules state no links to competitor websites, so remove them, the fact you try to argue the point says you haven't read the forum rules, might be an idea to


I have personally tried push pull and have found apart from extremely thick radiators it made virtually no difference whatsoever.

if your stuck for space go for a single fan.

Not quite sure what your asking here, the subject line says "Help me choose a fan" but you state you already have chosen the "best fan"

Thou I like the noc's I'm personally more of a noiseblocker fan, due to build quality.
example:https://www.overclockers.co.uk/noiseblocker-nb-eloop-fan-b14-1-140mm-fg-059-nb.html

various connection cables, solid build and a 6 year warranty.

I have the same experience with push/pull.

I have the same case running a quad radiator 45mm up top and i ran that in push/pull before and now i just run push. made no difference in temps. But i gained lots of clearance.

FYI i run two 480mm rads and one 240mm rad. All with a D5 pump res combo. Running a 5820X @4.4 and a GTX 1080. Running corsiar sp120 fans (not the best fans) for the rads and have them running at 38% fan speed. Keeps and system very quiet and still very cool.

The key is to have as many rads as possible and run the fans as slow as possible. That is the beauty of watercooling in a huge case. I am sure you will see better results with those Noctua fans than my corsair sp120's.

Noctua make nice fans, although they're almost all incredibly ugly. I've used them a lot on water-cooled machines I've made for work. Those 3000rpm fans are going to be incredibly noisy at full speed. If you're going to run them at lower speeds, do you really need the 3000rpm model?

I'd add another vote for the Noiseblocker nb eLoops. I have them on a machine at home and they're whisper quiet and do a good job cooling just in a push setup.
