How many standoff screws are safe for a heavy dual tower cooler?

[R2G_RR94]

I currently have a Asrock x570 motherboard that has 7 screw holes and was wondering if 6 screws would be enough to support a heavy dual tower cooler like the AK620 from Deepcool (1200grams).
Currently I have the screws in the following positions. Is it safe to install the large cooler? Is there any chance of motherboard bending and breaking?

That will be fine, no doubt.

The four around the CPU socket are going to the ones to primarily carry the load of the cooler, so it should be fine.

 

Generally I put in every stand off I can though. I even remove those alignment pins, and replace with a standard standard and screw. Is there a reason for not installing them all? If you can't the 6 will be fine.

The one that doesn't have any screw didn't have any stand off from factory so didn't bother at first as I had a basic cooler back then.

 

My motherboard is not a standard ATX, rather its width is quite a bit less so there is one column of less screws on the side compared to other ATX motherboards.

 

Maybe while installing the new cooler I will remove the motherboard just enough to install a standoff and a screw.

It should be fine, i have an nh-d15s (1150g with fan) on my m-atx board and since all 4 screws around the cpu are in then it works just fine. no bending or anything. i have 1 missing on the right because my case doesnt have a hole there to put another standoff

thats a higher quality board than mine so its probably a little stronger, so it can definetly handle 1200g if all screws are in.

 

also why didnt you install that last screw? did your case not have a place to put an extra standoff there, your case should come with an extra couple standoffs(mine did at least). If  its available and you have the time then you can take out the board and put it in if you can.

It will be fine

 

Plus don't forget the other components such as the io plate and GPU will offer some support tethering it to the case
