I did do a build with the TUF 3090 in the NCASE (which should be same size), and while it's a very tight fit - I did manage to put the 2 x 15mm fans under it - although needed to stick some rubber spacers between the fans frame and GPU shroud to maintain the gap.If your GPU temps are decent, then it probably isn't worth the trouble though.Also with the 30XX series GPU, you can get better temps with no performance loss with a small undervolt - using something like MSI Afterburner
