I'm really curious in knowing if full cover water blocks are better, worse, or no different from individual blocks in regards to performance. What do you guys think?
Alot of the fullcover blocks I've seen include VRAM coverage, though some I've seen only cover the NB and SB. if I did it I would want all three covered. Because of that I wonder if there would be a difference, performance wise of course.Originally Posted by Dr.GumbyM.D.;13037070
What I've gathered from reading is that the single block will reflect lower temps because it is less heat overall being entered into the WC loop/system, since you'd use air to cool the VRAM. If you cover the VRAM with a full cover block, it's that much more heat going into the loop, which requires more radiator and probably has lower flow rates.
I'm sure performance of cooling on VRAM will depend on your setup. If you've got a high air-flow system, then maybe VRAM sinks make sense, but if you rely primarily on your watercooling loop for cooling because you want to limit fans and fan noise, then you'd want a full cover block to ensure that the VRAM is getting the best cooling.
That's why I'm leaning towards the FC B. also the SB part won't get in the way of graphics cards.Originally Posted by t-ramp;13037133
As long as there is water flowing over the same areas, the difference shouldn't be much. I'd prefer a full-cover block, though, since it seems more solid and there are typically only two fittings to bother with.
Most important to me, more so than performance. It's safer to have less fittings to be concerned with leaks from.Originally Posted by t-ramp;13037133

but it have more o-ring sealing surface area, it's easier/less annoying to pin point a leak with fittings, plus if the full coverage block for the motherboard has an acrylic top, it might crack and leak anyways.Originally Posted by Dr.GumbyM.D.;13037192
