[HELP] Watercooling noob, want to watercool just my GPU

RipGroove · 18 Jul 2021 at 14:59

I have a 3090FE, it's hot, it's loud, I don't like it, it needs water, don't want to spend a fortune or even include the CPU in the loop currently.

I already know I'll need a waterblock so a Corsair maybe? (Again, don't want to spend too much). I don't want any RGB and would prefer everything was black, including soft black hoses.

My current case is a Phanteks Enthoo Pro which can take a 280mm rad up front but I can't really see any room for a reservoir/pump so I might have to get another case unless there are some fairly compact reservoir/pumps.

So, what do I need?

240mm rad in the front according to overclockers but could put a larger rad at the top which would give you room for punp combo.

I should have mentioned that I want to use 140mm fans because I already have a load of them all which match each other. So I'll need to use a 280mm rad.

That's actually not my case, mine differs slightly as it's the Enthoo Pro M Tempered glass version.

Corsair pump comes with extras like a temp sensor.

I’ve put the ek block on mine and it wasn’t hard but it wasn’t simple. The Corsair block is lot easier to put on as all pads are already on the block and paste.

I’ve you are in the Corsair eco system then you can sync up the rgb.

This is what I'm working with at the minute:

I did measure up to see if my 280mm AIO rad would fit up top but I don't think it will.

What about a 240 up top? I’d also ditch the aio and put the cpu in the loop as well. Cooling the cpu is very easy and then you share all the rad space.

Digital Dreamer · 18 Jul 2021 at 15:52

Or a 360 in the front and a little 120 on the top?t

I want to use my existing 140mm fans so the rad has to be 280mm.

Ideally yes but for now to keep costs down I just want to simply watercool the GPU.

You need a bigger case

Yes most probably but for now I need a list of what parts I'll need and any helpful info about how to make it all work. And I'll choose a new case in the meantime.

Digital Dreamer · 18 Jul 2021 at 16:53

Custom loop and keeping costs down don’t go hand in hand.

Don’t tie yourself to a rad size just because of the fans you currently have. You don’t have a lot of space so need to get a good rad in the front.

adding the cpu is like another £80 plus £20 for fittings so makes sense to do.
Also don’t forget a drain port

RipGroove · 18 Jul 2021 at 16:54

This is just a simple quick needs must exercise, I just want to watercool the GPU asap that's all.

I know you don't want to spend a fortune but that's going to be hard, the blocks for those cards are £300 alone I'm pretty sure? Say 80 for pump res, 60 for rad, 20 for fittings.

Ah wait corsair do a 155 quid block!

Spec states your case can have a 280 front and top, don't think you need a bigger case. You've got loads of room on that psu shroud for a pump/res, that or mount it to the 140mm fan in the front.

Corsair block is about £150

I figure it'll be fine for what I need. I guess I need a suitable case, waterblock, pipes, Res/pump, drain poet, fluid, and that's it?

Your case is fine, a drain port isn't vital really, I wouldn't bother in a single rad gpu loop.

So..

Block,
Pump /Res
Rad
6 fittings / more if you want rotaries etc depends on the run.
Tubing.
Fluid.

I'll see if I can somehow mod my case so the existing 280mm AIO rad will fit at the top and that will free up the front for GPU rad and reservoir then.
