Cooler Master 612 Ver 2 won't fit with side fan

[Henderson]

I'm putting together a new Intel system, 1151 CPU, Asus Z270F, Blackhawk case. The case came with 5 fans, 2 out at back and top, and 3 in on side with 2 at front.

The Hyper 612 won't fit in the case with the side fan on though, so had to remove it. In its place I installed another 140cm intake at the bottom next to the p/s, and another 140cm out at the top. So it now has 6 fans, 3 in from bottom and front, and 3 out from back and top.

Is that sufficient airflow to make up for the side fan I had to remove? Or would I be better getting a lower heatsink?

Thanks for any suggestions.

6 fans is plenty, and they are properly configured. Many cases don't have a side fan, you don't need it, especially with your setup. You are fine.

Do you have a link to your case?

I think you are overfanned(is that a word?)

A good cooling fan setup would be two 120/140mm front intakes which are filtered, and a single rear 120mm exhaust.
Such a system is called a positive pressure system and will keep your parts clean since all intake is filtered.
Two fans will provide sufficient cooling for a hot cpu and graphics card.
Whatever fresh air that comes in the front will exit somewhere, taking component heat with it.

This is the case (sorry I called it Blackwell instead of Blackhawk, my tired brain combined Blackhawk and Rosewill): http://www.rosewill.com/product/rosewill-blackhawk-gaming-atx-mid-tower-computer-case/

It came with 2 fans out (top and back), and 3 fans in (2 in front, 1 on side that I removed). They are all either 120 or 140 cm fans, the 2 new ones I installed are 140 cm. So now I have 3 in and 3 out.

The graphics card is a GTX 1070, if that makes a difference.

A balanced number of fans is fine, especially that some are 120 and others 140. You have proper airflow. If you remove the top 140 fan it will cause more positive pressure, that will help keep dust out, but with a balanced number of fans its unlikely to get dusty unless your room is.

For example I run negative pressure in my system, and I get no dust. My basement is just not dusty.

You should have no cooling problems, however you set it up.
Just because you have many fans, does not mean you have to use them.
More fans will mean more noise.
It is easy to change fans around.
I would start with just the two front 120mm intakes which are supplied and use a single 120mm rear exhaust.
remove the preinstalled 120mm side fan to clear your cooler.
I see the side fan as not necessary.

See how you do.

There's no carpeting at all in the house, just hardwood floors, that alone tends to keep dust down quite a bit. There's also an air cleaner in the room, and I will have filters over the intake fans as well, so I'm not really worried about dust getting in the system.

Sounds like I'll stick with the 6 fans then, unless they are too noisy, then I'll consider disconnecting 1 each in and out.

Thanks for the advice.

You want to set up all 6 fans to work in concert.
If you want to set up all 6 fans, set them up so all the airflow is directed from front to back and from bottom to top.
Front two and bottom as intakes, top two and rear as exhaust.

That is exactly how they're set up... the 2 top and 1 rear are exhaust/out; the 2 front and 1 bottom are intake. If the noise should be an issue, I'll disable 1 in and 1 out, to keep the airflow even, but I've never really had a problem with fans making noise, I try to buy quieter fans wherever possible.
