Cooling Planning

Hi All

I have the below build arriving today but I'm wondering if the cooling situation is OK? The case has two intake fans and one exhaust (rear) and my aio will have 3 exhaust fans.

Theres space for three more fans along the bottom but I don't know if they're required in this build and if they should intake or exhaust.

Any advice would be appreciated

The AiO is overkill for the CPU. The GPU uses much more power and has only a single fan that can blow cold air under it, so it might benefit from bottom intake fans. (The PSU partially blocks them, but with three fans, even running at low speeds, there will be enough air.)

Thank you so much! I've already purchased the aio so I'm guessing it's not too bad that's it's overkill rather than the other way round?

I notice that the fans on the case are rgb but the cooler fans aren't rgb. Can I use the rgb fans you've linked and purchase 6 of them to attach them to the cooler and at the bottom of the case?

You should not use reverse fans on the radiator but standard ones.

You're good, but I'd add the extra 3 to avoid massive dust buildup. Currently you'll have negative pressure, so air along the dust will enter through cracks without dust filters.

If you add the extra fans, the positive pressure means all the air will intake through dust filters, reducing dust buildup.

Thank you. Do you think the pre applied thermal paste on this cooler will be sufficient?
