Scythe 120mm Slim on a Radiator

[turquato]

PARTS IN HAND:

 

NZXT S340

DeepCool Maelstrom 240T AIO (wih 2pcs stock fans)

 

 

 

WHAT I WANT TO DO:

 

Could I use 4pcs Scythe 120mm slim fans (12mm thick) on push-pull config?
Are these fans any good? If not, what are the best alternative slim fans I could get?

You can do that, fans are decent, but it wont outperform the stock fans that only push.

thinking about what you said, I still haven't bought the scythe slim fans, and I might stick with the current stock fans.

but if anyone has other inputs about this, please comment on.

Why not?    

 

I've tried the push-pull config in the case before, but because of the cable shroud of the S340, I was not able to fit another 120mm or 140mm fan on top of the rad to make it completely push-pull config. So instead of using four (4) regular thickness fans, I was only able to use three (3) 2fans as intake (push), one (1) at the bottom for pull and the top was left empty.

It's more costly without much practical benefit. It may be aesthetically pleasing but how much that's worth is up to you.

In terms of performance and noise, you're probably better off with a better 25mm thick fan like the NF-A12x25. Slip Stream Slims aren't very well suited for dense rads like that on the Maelstrom 240T. Thicker fans are better suited. 

The S340 bracket can be removed.

I agree that it'll cost me, but compared to the price of one (1) Noctua Fan brand new, I could buy me about 4-8 scythe slim fans and still have extra.

 

How can you say that it has no practical benefit? Have you tried it before or have read something about it? Can you point me to it please.

Yes, I'm aiming for aesthetics but I am not keen on removing the bracket as I am using it as the tie down point for some of the thick mess at the back.

That's pretty cheap (3-6 USD per fan?) although still not a great config to begin with.

Push / pull won't increase cfm past that of one unobstructed fan. The Slip Stream Slims have low cfm and not very high static pressure. Similar fans with many small blades generally don't perform well on rads due to the lack of static pressure. 

You can see how much airflow can decrease when obstructed by a rad with only 16 fpi. https://www.overclockers.com/noctua-nf-a12x25-fan-review/

The fans with slimmer fan blades like the NF-S12B perform dramatically worse. 

The Maelstrom 240T uses higher fpi which would require even more static pressure for similar performance. 

 

I haven't seen examples of this done since it doesn't make much sense for the reasons stated above. 

That being said, it'll still work fine if you want to do it for the sake of aesthetics and there's nothing wrong with doing it for that reason.

 

If you do end up doing it, I'd be curious about the performance difference with 100% fan rpm and your subjective take on noise at least when compared to the stock fans.
