So about 2 years ago Microcenter had this 4090 block on sale for $50. Being bitspower, I figured it would be OK, but the deal seemed to good to be true.
Since I put it in my loop I have had issues with corrosion and green floating stuff (not even my main concern and has been mostly mitigated at this point)
the bigger issue to me is the hotspot temps. It seems like I have to reseat the card every 2-3 months. Temps will be great (45-50* core and 60-65* hot spot) but then I will check the temps after a while, today my core was 55-60* and hotspot was almost 100*C. Im getting sick of taking the loop apart to reseat this block. in the 15 years I have been watercooling GPUs, I have never seen this before.
Anyone have some experience water cooling the 4090 FE? Does this occur with all blocks? I will drop some $$ and buy an alphacool or EK (ugh) block right now if I dont have to deal with this **** anymore.

Corrosion and bio growth should be your concern as they can and will destroy your loop.

Corsair makes good and cheap blocks, so does AC.

Optimus if you want to splurge.

I mean i can drain the loop and refill in a few seconds. I have that issue mostly dealt with I just had to change up my additives a bit.
