They will be somewhat cooler and quieter for sure, though EVGA uses a pretty average PCB design and power delivery, so you shouldn't expect higher OCs than some other air cooled GPUs

[SolarNova]

Sure they are.

 

But just like with AIO for the CPU, i personaly recommend people skip them.

Ether air cool, or go with a custom loop.

[Mick Naughty]

Sure they are good.

Its not worth it adding an aio cooler onto a GTX 1070 at all. Complete waste of money since you can adequately cool a 1070 even with a relatively low end cooler. Also the fluid will inevitably permeate through the rubber hoses, so in the worst case after some time you are stuck with a completely worthless cooler that you cant even refill.

This is only partially true.

 

Sure you can keep the card at a level where it won't have thermal issues, but with the way the 10xx series works once temps hit 55-60C it starts to lower the boost on the card. So even though it isn't anywhere close to thermal limits it has a soft throttle at much lower temps that increases as they rise. So when you are able to throw these cards under and AIO like this that keeps them temps in the 45-55C range you don't see those boost clocks dip./

I have 2 1080 Ti hybrid and love them. They boost immediately to max and basically stay there. The cost premium was worth it to me.

Haven't ever seen my Gigabyte GTX 1070 Mini do this. It keeps boosting beyond Gigabytes OC spec even when it goes above 70C. Sure, fan ramps up, but it doesn't throttle at all.

So let me clarify. It isn't exactly throttling, but the way boost 3.0 works. It adjusts the boost rate based on temperature. So once temps hit 45-50C the boost frequency will slowly start to decrease in steps. So you might be boosting at 2ghz at 40C, but at 50c you are boosting at 1961. Then at 60C that might be reduced to 1896... and so on.

 

So if you want to maintain a maximum boost frequency you need the best temps possible. You cannot change the way the boost works btw... so all you can do it gets temps as low as possible.

More thermal room on Pascal is largely unnecessary, especially on 1070.  Maybe if you want to trade some fan noise for pump noise, or like the look.

[Mick Naughty]

They throttle at 39-41. So if someone ways they haven’t seen it, they don’t know the gpu that well.

Ok got it. The delta between the boost states will decrease. But doesn't this mean that you had to keep your gpu below 45° all the time for it to stay in maximum attack mode? Will a single, thin 120mm rad even be enough to keep a card like a 1070 at around 40° max at 100% load?

I have never used a hybrid card, but I do know that GPU's have much better gains when using water cooling than a cpu (at least in thermal drop). I run custom loops, but in my experience a 1080TI with a nice OC will stay under 80C if you are ok with keeping the fan speeds high, but I can drop that same card in a water loop and watch the temps hit 32-40c under full load. Now I do have more rad space than say the 120mm AIO, but from the numbers I have seen they still perform very well.

They are showing sub 30c temps under full load it looks like. I am a little skeptical of that unless their ambient temp is 18-22c... or maybe I am pulling the old man card and remembering higher temps than I actually get on custom water >.<

Yeah he got a 600 mhz oc from base clock and still got 29c. That does not seem legit.

This one is from a source I trust... so still sub 40C when overclocked. That is a big gain over the air coolers which will hit high 70's with a aggressive fan profile.

[Mick Naughty]

Jesus, even with several radiators, the two I ran never went under 40c in real world testing. 

[Jon Jon]

I'd say yes.

 

My next video card I may get as a hybrid and stick the fan at the top right exhaust.

 

My RX 580 gets so loud once I really put a load on it...the rest of my machine is silent.

 

Those worried about the AIO eventually becoming useless, I would argue that the card will be next to useless by the time that happens.

 

@black0utm1rage, what's the typical time frame to expect AIOs to start creating this issue?

Also a little sceptical of that. Sub 30c seems a bit too good to be true, maybe the fan and pump were run on full tilt during testing. But nevertheless, I did some research on my own and found similar results. So from a pure performance standpoint the aio 1070 seems to be worth it. (Obviously completely disregarding cost relative to GTX 1080 or 1070 Ti models and relatively small real world gains from an air cooled 1070) But I'm still kinda hesitant about aio on a card like a 1070. I mean why go for the high-end model and water-cool that one? Is the performance difference between this and a regular 1070 really worth the price? And if you have money to spare after putting a 1070 in your shopping cart, why not go for a 1070 Ti in the first place.

Really depends on the aio. I had a Corsair H55 branded Asetek 120 mm AIO which lastet only just over a year. But thats pretty much the worst possible case I suppose. That one was taken to its absolute limits and frequently went over 60c ~ 70c. I had it running on an overclocked 3930k which generated a lot of heat, too much for the poor little 120mm radiator. On the other hand I also have a Silverstone SG03 (Apaltek) in my main pc since 2015 and it still runs like a champ, cooling a 4770k. Only complaint I've got with that one is that the pump is fairly audible.

 

So the bottom line is: If you frequently boil the hell out of the coolant, it can evaporate and will permeate fairly quickly.

The reason they did it for the 1070 and up is to help with small form factor builds too imo. I know a good few small form cases with enough room for say a 240 and 120mm rad. So you could toss a 240 on your cpu and the hybrid on the 120 and get better component temps and likely reduce your case temp as well. As opposed to running 2 air coolers in a tiny case where airflow can get all messed up fairly easy.
