Change from a 360mm AiO to a 280mm for a 12900K

I am changing my case and want to top mount my AiO so it can be an exhaust however I am struggling to find a case that fits and has a 360 top mount. 

As a result I am looking to change to a 280mm AiO and wondered what experience people have had with such a hot chip and the smaller radiator. I get ~90c with a 1.220v undervolt with my restricted airflow case and fans maxed out.

Will I be okay with the 280 or should I stick with the front mount in the new case?

I think front mount should be fine. More cold air for your CPU, Less cold air for your GPU, but from your spec it's 1080, so I don't think it'll suffer much.

Just reverse the placement, top for intake, front for exhaust.

I am hitting high 80s with my 1080 during gaming on the hotspot and 75ish on the core/GPU, same temps before and after repasting. My case does have fairly restricted front intake due to the glass panel and removing it does drop temps about 5 degrees on the CPU but I forgot to check the GPU. That is my main concern, especially as I would like to upgrade to a 40 series card around November (or when ever they come out) and that will produce a lot more heat than the 1080.

This is a very good solution but I would hate to have the back of the fans showing at the front of the case. It has a glass front which is what restricts the airflow. I like to see my RGB unobstructed 😄

just put the rgb fans as the radiator fan, easy peasy.

Well, who knows about something that isn't even released yet.
