Hello, I recently completed a build in a Phanteks P400a with a R5 5600X and soon to be a 3080 Founders Edition. I am using a gelid phantom CPU cooler with 2x 120mm 1600rpm 60CFM 2 static pressure fans. I decided that I want to swap out one of these cpu fans to something with a bit of RGB on(phanteks halos rings won't work on this setup). So I have been searching around and come to find 2 fans that I think are quite well performing that include RGB: Silverstone Air Blazer 120r and cooler master sickleflow v2. I have heard some people say in a multi tower cooler it is usually best to have fans with the exact same or very similar specifications. I am wondering if this actually matters? Just a note, whatever fan I will be buying I will be buying 2 of because I need to fill a rear exhaust fan slot too. Just looking for some advice from the cooling experts before I make the order. Thanks for your help!

Yes, you should be looking at the same fans for push and pull irrespective of the cooler being an AIO or a tower/air cooler. If the fan you're using for push is mismatched than the one for pull, the temps will suffer due to improper airflow...though I can be proven wrong if you spend the time to test out what nets you better temps.

Just an FYI, look for high static pressure fans, like the one's made by Swiftech's Helix or their ilk or if you can, Silverstone's Air Penetrators. I didn't mean to source the same fans as the one's that you currently have with the cooler.

Great, thanks for your reply, do the fan specifications need to be EXACTLY the same or just fairly similar, for example the RPM on the CM fans is 1800 compared to 1600 on my default. Thanks for your help
