I am considering an AMD Fury X, which comes stock with AIO water cooling. Due to the configuration of my case I would have to put the radiator underneath the card itself. That would put the pump at the highest point in the loop, since it's on the GPU. According to the Fury X's manual: Do you think that's a strict requirement? I would have thought that the relative position of the radiator would not matter for a closed-loop cooler.
If there's any air in the loop at all it could just end up sitting in the pump and the coolant may not get circulated. It's possible they leave some air in it to make the filling process easier.
It's a sealed unit so won't need bleeding or anything like that, so you can pretty much put it anywhere it will fit. Doesnt matter what way up it goes.
I asked a similar question but with regards to the EVGA 980ti hybrid - the responses I had were all the same which was that it shouldn't matter for an AIO cooler. What case do you have btw?
So the consensus is that it shouldn't matter. theshadow2001's point about leaving air in the loop sounds plausible though... maybe once sites have cards for review, I could persuade someone to test it to be sure. I have a custom-built case. I made a thread in the modding forum about it. There is physically room to place a radiator at the top of the case above the CPU, or I could cut another hole somewhere, but that wouldn't be good for cooling efficiency or noise.
Very nice indeed I would definitely just use one of the mounts in the bottom of the case and be done with it - I've seen plenty of pics on t'internet of people mounting the rads for AIO coolers in the bottom of their cases I presume without any issue. Sounds like you'll need to be fast off the mark if you're hoping to bag a Fury X on launch date - I read on OCUK earlier that they expect their allocation of them to sell out in a matter of minutes...
As final confirmation that this will be ok, there are some pictures of a system with 4 of these cards in it, two of which have their radiators placed at the bottom of the case. It was built by an AMD "Technical Support Engineer", who should know what he is doing. Now I have to wait for the damned things to be in stock...
