Absolutely. Alphacool make the block - and yes it's really cheap compared to what EK are up to (honestly it's madness) - and it fits every inno3d 4090 according to their fitment guide. Still, the 'basic' inno card on OC lists at 2k (up from ~1750 pre launch) on OC. Of course inno will say you've dumped warranty by fitting what they do anyway... I don't know, I've got a 3090 now and the cash to swap but I'm put off by both the insane pricing (it's not 3xxx launch ffs) and also, frankly, this whole battle the website to order something process. I'm not interested in spending my day trying to get an order through and would rather just preorder (and pay up front) and wait patiently for it to come.
OC you're not making me excited with your current process. I get that preorders are harder work for you but take the feedback nonetheless.
