Water cooling just GPU?

I see lots of people are water cooling the CPU and only sometimes have a loop that includes the video card.

My 980ti reference hits 84c in games, the 5820k barely breaks a sweat.

I could wait for the AIO to get in stock for the 980ti, but I think it would be cooler to do a water cooling loop for it instead. I would leave the AIO on the 5820k.

Thoughts?
 
Absolutely nothing wrong with that. It would be cooler and quieter for sure.
 
The thing is, once you have the hardware for watercooling the GPU, adding the CPU is just another $30-50 for a decent block. When compared to the rest of the watercooling equipment ($400+), it really isn't much, that's why most people do a loop that includes both. Plus, this method allows for a radiator setup that fully utilizes your case, and any leftover cooling capacity not being used to cool one component is used to help the other component run at lower temperatures.
 
see reference is the only one with a temp issue. My 980 TI G1 can run at like 65C (IIRC) with 1550 core clock on F@H all day long (like 600-700k PPD). For certain games that actually require large TDP I see at 1500 75C peak and thats with 120-130% TDP. Water really does nothing if your GPU has a decent heatsink. Same goes for CPUs. There are a few quality air heatsinks that can almost match even the best AIOs like 100i GTX. Only a custom loop makes a real difference and those run massive moola. I mean seriously 100-150 bucks for a GPU block that is not reusable? At least CPU blocks have some sort of re usability. I would totally water block my GPU if those blocks weren't pricey as hell but there really is no point when air heatsinks can keep temps in the 70s worse case.

Maxwell doesn't have any actual benefit with OCing with lower temps unless they are LN2 low temps so there is no major benefit to water block maxwell because 75C is not that bad. This is obviously assuming noise is not a factor. If it is then by all means water block the crap out of everything.
