Different spec fans on a push/pull config

[Marfe]

Good day!

 

I’m planning to buy a H150i Pro and LL120 3 pack to make a push/pull config on my PC (LL120 = Pull). I’m just wondering is it a bad idea to use different spec fan on a push pull config?

 

The fans with the H150i Pro specs

 

While the LL120 specs are

 

 

The fans that are similarly spec with the fans of the H150i are the ML120 Pro RGB

 

 

But unfortunately it is not available in any of the stores here in Japan

It doesn't really matter, so long as you don't have too many fans (after a certain point, adding more fans doesn't improve cooling) and the ones that you do use aren't too loud for you.

Just by thinking about it with some common sense I would say don't do it... 

 

Why? if the pull fans are getting more pushed than they pull, meep you see the problem...

if the pull fans pull more than the push fans can push, meep again... a little thinking and the fault may open itself =)

I've used mixed fans in push/pull before. It's not ideal but it's not "bad".

 

You will still get a noticeable temperature drop going into push/pull (from only push or only pull), even if the fans are of different specs.

Conversely, you'll be able to run both fans slower and get the same cooling performance if what you want is to reduce noise.

 

I achieved this on the old 120mm AiO cooler to my GPU (before I switched to a custom loop).

And yeah, even with mixed fans, it was still better and both fans are still fully operational today after that experiment. They're just in different parts of my case now.

 

There's no harm in it. You won't break anything.

if you've got spare fans lying around and space enough to go push/pull on a radiator, then there's no reason not to do it.

Honestly you have a thin rad its 27mm thick,Push pull is overkill for that and you might get one degree cooler with it.The reason you hear push pull is years ago before static pressure fans we had to run it.Today only time its really needed is a thick rad like 50mm or thicker.
