Cooler Master HAF X High-end fan replacement

[XAKEP]

Evening guys ! I am trying to get my stock fan replaced with 4 pin high-end fans that will work with my case. I found nice one for that back but front and side I can't find a proper one. I tried to get a side fan, I matched up size but screw positioning does not match original and wouldn't work.

So can anyone recommend 4pin "premium" fan that will fit HAF X case.

Thank you.

Here's a guide to removing the side fan just for the sake of relevance. The fan on the side panel looks more akin to a 200mm fan but with mounting holes for 2x120mm and 140mm fan mounts. You;d be best served by getting a ruler and measuring the hole distances(center to center on one side) on your side panel.

Outside of that you can look towards these suggestion:
