What's the general consensus on universal GPU blocks? + Questions!

post #1 of 15
Thread Starter 
Basically topic. I like the idea of being able to move it to a new card if need be, otherwise can anyone recommend a non-reference and reference 6950 block?

Also, would the XSPC 750 RX360 kit provide enough oomph to cool my cpu, and 2 gpu's?

Thanks everyone!

I'm in the same boat as you, as I have the same pump/res (though also a Swiftech MCP655 and another dual bay res), a 360mm/60mm-thick rad, and 2x XSPC universal GPU blocks. I haven't completed my loop yet, so I have no idea how temps will be like, but the pump/res will be good enough to cool them.

If anything you could just run it off the 360mm rad for now and see if you like the temps you are getting. If not, you could always add a 120mm or 240mm rad to your loop. It may also depend on if you use AMD or Intel, as Intel chips run much hotter than AMD chips.

When you test them could you perhaps post the results?

Any other opinions?

I posted a lot on this topic, that is regarding the fullcover *6950s. Basically ref 6950 2gb = 6970 waterblock, aka rev1/ver1 block. Non-ref or revised 6950 1/2gb = 6870 waterblock. Within the non-ref, the DCII, TF3, Lightning and Windforce are all full custon pcb so nothing fits them at all except a gpu only block.

Gpu only blocks are obviously very flexible, but they can lead to a path of false security. You spend a lot more energy on cooling the gpu and end up with the same air cooling on the vrms. Sometimes ppl even neglect the vrms and that can spell disaster. Anyways, if you do go gpu only be sure to pay attention to the vrm cooling, its just as important as the gpu.

Universal blocks have upsides and downsides. They do a fine job of cooling the core, but you do need to factor in additional money for cooling the vrm's and memory, and often it's difficult to get heatsinks on a few of the memory chips because of the barbs. Once you factor in the cost of the added accessories, you can easily be up to the same price as cheaper full-cover blocks that are less hassle (my 460 blocks were $60 each new, on sale from $80 normally). While you would have to sell full-cover blocks when you upgrade, used blocks for popular cards are always in demand.

Sweet! Thanks for the answers guys!

My first card is a reference 6950, the second is the dirt 3 edition I think (I think it's the same card just wasn't named 'dirt 3 edition': I.e. the dual fan design. Sk I should be right with a 6970+6870 block?

At this point does anyone think it's worth it to WC these cards?

I think its worth it.

That said your dirt3 card is a modified non-ref 6950 so it doesn't have a fullcover block.

So does that mean I need a 6870 block or I have to cool it with a universal cooler? Sorry! Very new to all this. c:

Oh and as soon as I figure out how to, +rep to all those who helped! Appreciate it!

There are very limited fullcover waterblocks for some non-reference cards, but most of the time, you can only use a universal waterblock for non-reference GPUs. You will need some heatsinks or direct airflow on the VRMs and VRAM. I'll be getting the rest of my watercooling stuff later today, so I'm hoping to start on my loop this weekend and I'll definitely have pictures and results for you.

You could do that. Personally I would just get universal blocks for both the cards for a more unified look.
I'm going to pick up some ek-vga bridge edition's my self. I think they are the best option for crossfire/sli if you are going to use universal blocks.

Note unlike the cards in the picture you need to have passive heat-sinks on the memory and especially mosfets. Depending on the design of your cards you could possibly just use the stock uni-sinks for this.
