3090Ti Zotac Gaming water block

[Zwolin]

Hi,

 

I'm looking to watercool my Zotac Gaming 3090Ti and can't find compatible waterblock, at least on a first few pages of google. Could you recommend anything?

 

Also, how many 120mm equivalent radiators would I need to cool 2 of these? 360mm would be enough? I don't care to cool them to near-ambient, I just need them not to overheat (<70C) under 24h load @ ~90% non-OC power.

 

 

Background: I'm building a workstation (at work) and was given R9 3950X and Asus CH VIII Formula MoBo and 2 of these cards, but with stock air cooling they simply do not fit. I figured it'd most likely be cheaper to watercool them and fit 2 onto one CPU+MoBo combo, rather than building (and buying parts for) a second rig. The workloads we have can easily be handled by 8x connections, so TR platform is not needed.

 

Any help would be appreciated.

I think 1 360 would likely be enough. It’s 1 1/2 fans a piece.  It took the 12900k to push cpu cooling above 1 fan.  Many AIO 3090s have only one 120mm AIO rad. If it’s shy it won’t be very shy.  Depends on the radiator of course.   I have no solution myself for the zotac problem.  If it’s a non reference board something has to be made for just that board most often.  If it is a reference board you can use any reference cooler though.  Zotac has a rep for doing unusually sized video cards.  Minis and stuff.  They do all sorts though.

Thanks, I decided to go with 420mm for a bit of overhead and connect CPU to the same loop (as the Noctua that we used - 15 something, largest one anyway - wouldn't fit behind the backplate).

look for bykski N-ST3090TIPGF-X

 

depending on how big is your case, always go with a D5 pwm pump (or compact DDC3.2 with heatsink on it)

Why this particular pump/pumps?

Those are really the only choice pump wise. Unless you want a manual d5.

D5 is reliable and long lasting.  So many others are so far from that they might as well not exist.   And many don’t anymore.  So much so that a lot of pump/rez combos have d5s in them.
