The 7900 XT Hellhound block fits perfectly, keeps temps in check. No hotspot issues here, hotspot stays under 50C after lengthy sessions. Great block!
Durable and easy to install. Don't forget to install the 2 small pads as it's easy to overlook
Never found place to put inner screws but it's working fine so don't care.
I wish it came with installation instructions
Firstly. I can confirm this block works with all PNY 4090 cards. I have the PNY Verto Triple fan 4090 (all black model) and this block mounts to the GPU. I have this block in a triple 420 radiator loop and at idle GPU temp is roughly 23-25 degrees. Peak temperature under extreme 30 minute stress test was 41 degrees. There is plenty of headroom with temps.
RGB is awesome on this block. By far the best block out for PNY 4090 GPU’s
