There is no significant temperature differences between the 5090 AIB models. This temperature issue is only applicable to the 5090 FE model as its memory temperatures are soo bad compared to AIBs. All AIBs effectively have the same cooling range and you only pick up what makes less coil whine and also which look you like. You can get a MSI Suprim that has a 5 degrees better temp on memory but you could also end up with a loud coil whine. If your PALIT 5090 is quiet with no coil whine and its keeping memory temperatures below 80 for extended periods then I`d suggest you stick to it. I have tried many 5090s AIB models and found Palit to even overclock better than ASUS and to be low coil whine than the ASUS and MSI 'premium' cards. MSI and ASUS tend to use overkill capacitors on their 5090s which are notorious for awful coilwhine.

@OP: I’d be careful with WireView, seen on Reddit that it burns

Can’t remember exactly but it adds an extra resistance (2 extra connectors ) to the whole gpu power supply which isn’t good, especially when the 5090 draws significant amps under heavy load. Personally using good PSU (Corsair hx1200j) with their angled gpu cable and don’t expecting any issues.
BTW, apologies for jumping in on your ad

Should be hx1200i of course

@cps_goodbuy I`d avoid Gigabyte cards as they cheap out on a lot of things. They have also applied soo much thermal paste on their 5090s that waterblocking it would be a nightmare. Funny enough, Zotac 5090s are the only ones to have a fuse on the power delivery meaning your core is super protected from any power shorts, Palit were the most quiet (coilwhine wise). Suprim is also good but including Astral, its only chosen for the most part due to aesthetic. Be careful of getting waterblocks from Bykski as numerous 5090s PCBs have been warped overtime due to uneven pressures in the block design. Focus on the big guns, Optimus, Watercool and EKWB for their full metal GPU blocks if thats the aesthetic you want however your GPU options will become limited. In my opinion, no one makes waterblocks better than Watercool, and their aesthetic is top and minimal. Alphacool has too much acrylic for my liking. Bykski has the full metal server blocks however just be aware that you may end up warping your pcb and damaging the GPU as its become a common occurrence. Overall, I`d keep the Palit and get the Watercool Heatkiller block and call it quits.You will find out how annoying coilwhine is if you get an Astral/Suprim and waterblock it. Remember, when you add a block, fan noise is gone and coilwhine becomes more apparent.

I see. If that`s your plan for the Gigabyte then go ahead and get it but they are notorious for cheaping out on components. They sorted the thermal paste leaks last year however they add soo much of their hybrid thermal paste/putty on their VRAMs and capacitors that it made their cards very annoying to waterblock as it has taken people hours to remove the paste from the PCB to apply the block thermal pads. Nothing guarantees the cleaning will leave the small PCB components unharmed. If full metal block is what you want, can`t go wrong with Optimus however you`ll have to get a PNY card. Bykski might be an option as the current horror stories could be from user errors however best to know the risks before going down that road.
