RTX 3090 Watercooled Temp

[Petrolhead]

Just wondering those that are fortunate enough to have a 3090 and have then fitted a water block to cool it what temp. under load, is it reaching?

Also does the backplate get hot?

my temps under load, ie sim racing on a triple screen is cpu and gpu about 55deg. this is one loop using a corsair xr7 360 rad on the top and an ek pe 360 rad on the bottom of the case (O11d). both top and bottom fans blow out

however I am greedy and would like even lower temps

would it make much difference if I replace the bottom rad with another corsair xr7?

also would I be better off having the bottom rads drawing air in as opposed to blowing air out?

I don't think you'll see a massive difference changing the PE360 to a XR7 55mm 360. I would contemplate trying something wild like an external rad for a major difference in temps.

I'm currently figuring out an additional external 360 radiator to cool the 3090 and see how big of a difference in temps in makes with the use of QD's.

interesting not seen any builds using an external rad

what about my question re air flow on the bottom rad

That seem very hot epecially the CPU

Whats the room temp

Still toasty hot.

I have an Intel i9-10850K and RTX 3090, currently playing Project cars 2 temps 54deg both cpu and gpu

I am struggling to get a flow diagram in my head but it looks a bit odd.

so, correct me if I am wrong, water flows from the reservoir to the GPU block, then to Mosfet block, then CPU block, then to side rad, then bottom rad, then top rad and back to reservoir
