Good morning you beautiful people!
 
I am waiting for my yet to be purchased 3080 FTW3 Ultra Hybrid card and am starting to look at what i need to do in order for the card to fit. I currently have an EVGA 280 AIO installed at the top as recommended per the manual. 
 
So looking at my build; even with using my Phanteks Enthoo Primo (which is a liquid builders dream case) i do NOT have room on the top to place the 3080 FTW3 Ultra Hybrid card radiator and fans,.... Mounting in the front also does not seem like an option due to the radiator tubes being somehwat short (which is actually a good thing to help fight liquid diminishing over time), mounting at the bottom is asking for early pump failure and all sorts of issues, which brings me to my question:
 
@EVGA: Where would be the best and/or second best radiator installation recommendation if one of your products (EVGA 280 AIO) has already been installed at the top per manual recommendation, please??
 
I hope this can be answered and also may help some other people out there that may run into this dilemma :)
 
 
Thank you all for your time and help!
 
 
Have an amazing rest of your day!

    Won't fit in the front even if you remove the drive cages?  The tube length is 400mm.  
     
    Actually even if the tube length was long enough, I'd be worried that the pump is now above the radiator.  
     
    I'd get a new case lol.

    Lol thanks for the reply! The case is $250 so yeah not replacing that one! :)
     
    I am thinking about double stacking the new 280 radiator underneath the already installed 280 AIO, yet not sure if it is a good idea and/or will even work.
     
    removing the front bay could work, i need to wait till i actually get the card i geuss! I appreciate your insight though, thank you!

    I believe they also recommend installing The radiator for the hybrid at the top as well.  They generically say this because it is the safest position to not prematurely wear out the pump in case of low coolant levels.  Mounting in front is fine.  If mounting in front ideally you want the radiator oriented in such a way that the tubes are on the bottom going up to your gpu or cpu and the actual radiator is higher than your gpu or CPU pump.  The whole radiator doesn't need to be above, just an inch or so.  I have a 280mm corsair aio mounted in the front and my 3080 hybrid radiator mounted on top.  I would not mount the GPU in the front as that will put some serious heat inside your case.  The CPU doesn't come close to putting out as much heat as the GPU under typical gaming, which is why I have it as intake in the front.  My GPU runs between 50 and 55C like this while running time spy stress test for a lengthy period of time.

    Just make absolutely sure that the pump is not above the top of the radiator (not at the top of the loop).  If it is, air bubbles will collect there which can result in burning out the pump, stopping all coolant flow, and potentially frying your cpu (in a worst case scenario).

    I've got mine as top mount intake with push pull fans.  Works ok, but I feel like it could run a bit cooler.  About 55C at about 350w-400w gaming load, 60C at max power ~435w average 485w peak Furmark. I'm questioning if it pulling in warm exhaust air from the back of the pc or heatsoaking from the MB vrm.  Can't fit my new CLC280 cpu aio at the top in a new Lian Li lancool mesh, have it front mount tubes down.

    I have a 280mm AIO as a front intake and the 240mm Hybrid GPU as top exhaust.
     
    Should I make the top AIO as an intake instead?
     
    I have a 120mm back exhaust. All in a Meshify C mini

    I don’t know about your set up, but I had mine set up as top exhaust and the biggest factor on decreasing temperatures was taking off my top dust filter. I dropped 4-5C by doing that and it isn’t a huge deal as it exhausting anyway.

    From my daily reminder in the 30-series queue thread:
     

    • Keep in mind if you're ordering a Hybrid card: the tubing is 400mm in length, and the radiator + fan combo is about 56mm thick;  Hybrid card radiator exhaust can be in excess of 34-38C air, having it setup as intake is not recommended even in a CPU AIO/GPU AIO setup, as unless you have a very high core count CPU that puts out more than 400W of heat, the GPU radiator will always be the hotter of the two.

     
    So if at all possible, setup the GPU radiator as exhaust and CPU radiator as intake.  As long as part of the GPU radiator is above the GPU pump/card level, it'll be fine.

    I had same issues, dg77 case, clc 280 with 3080 hybrid(was fine with 1080 hybrid since one fan)
     
    Had to change case to Lian Li o11 Dynamic XL. To to mount clc 280 on side, hybrid on top.
     
    Im done with the clc280 though, doesnt fit well in anything, even this case.  Going with a 360, waiting for the arctic cooling one to come back in stock.

    I take my dust filter off when I game, and I'm experimenting with a cardboard chimney-duct to take hot air off the back of the PC up into the room instead of circulating it around the case.
     
    Mind you, even without a duct it's way better than a top mount exhaust.  That's just dumb.  There's no way a rad fan is spitting out 38C air, unless you're hammering the GPU with the fans turned down and the coolant gets super hot.  I'd need a thermometer probe to test though.
     
    My last case had a 2080 Ti hybrid with the rad fans intaking push pull at the bottom-front of the case, it always got cool air off the floor.

    Just ran some Furmark 2560x1920 2X MSAA for 10 minutes, gives an average 445w load.  54C with max fans (rad fans on case fan hub with sata power, on switch MAX full 12V, pwm and tach signal to GPU).  Internal MB temps were nominal, system temp was 40C max. +120 core, max voltage and power, 3080 FT3 hybrid push pull top intake, rear case chimney duct. 
     
    I'm going to build a good cardboard duct and paint it black.

    I am using thermocouples to measure it, that measurement is accurate.  34-41C (the highest I've seen) is how warm the exhaust air gets during Cyberpunk 2077 sessions with 70-72F ambient temps with the GPU radiator setup as exhaust in a high-airflow case.  And that's with the eVGA fans ramping up to ~2400RPM & EK Vardars on exhaust at ~1800RPM.
    It's a 240mm radiator trying to deal with 400-500W of heat dissipation, it's going to run warm, you could tell that by touching it when it's under load.
    That'd be like trying to run an overclocked Threadripper on a 240mm radiator... not gonna work out too well in terms of how warm the air coming out of the rad will be.
    On a 3080, it would be slightly lower, but not by a lot, my numbers are coming from a Hybrid 3090 running an OC/Undervolt at 2040MHz @ 1000mV, and I'm seeing those exhaust temps as measured by a thermocouple in the exhaust-air path of the GPU radiator, that connects to my motherboard & gives a temperature readout, which is the temp I use to control the GPU radiator fans.
    My maximum load temp is in the 52-57C range depending on what clocks I'm running & how warm my ambient is because it's winter and all.
    What kind of whacky setup did you have for 23C average temp on that test, is that an error on the part of 3Dmark's reporting software, or what, because there's no way that's just on the Hybrid with nothing special going on, literally impossible unless your ambient is arctic air.
     
    Edit: one should also keep in mind, the GPU block & radiator aren't just cooling the GPU core, they're also removing heat from the vRAM with the copper plate that connects to the edges of the GPU block - that's another part of the reason why the GPU die temp doesn't directly translate by itself to GPU radiator exhaust air temps.  GDDR6X runs pretty warm.

    Only reason you're measuring those exhaust temps is because you're putting the warm air from the MB and CPU AIO through it.  The delta-T is more like 10C.  My system (MB system temp) idles at 30C and gets up to 40C with the hybrid rad blowing over the MB at 400W+ board power.  That's with the GPU idling at 22C.  Try measuring in free air.  
     
    I'm running my rad fans intake at max speed now, at idle.  21C idle gpu, 27C system temp. After running at high power, then returning to idle, the GPU will typically be in the high 30's, which is a good indicator of the coolant temp since it's thermal mass is far higher than the GPU chip itself or the ~10W heat load of the GPU chip at idle.  Thus the coolant temp is rising by about 15C at high power, when the rad is fed plenty of fresh ambient air with fast push pull fans.  If the coolant is about 37C, there is no way the air dumping into the case is any higher than the low 30C's, worst case scenario, probably more like the high 20's with fast push pull fans.  Not a problem unless you're running your CPU at very high power levels, in that case you should tune your system accordingly.
     
    23C is with the PC more or less outside with ambient air around 0C.  Maybe like -3C since it idles 2C above ambient with max fans and it was idling at -1C after cooldown.  That's #5 in the US for a 3080 in Timespy GPU, btw.

    Here's after a few minutes of Furmark and Prime95 AVX running at the same time.  UPS was showing 900w, but that's only 720w over idle. LOL.

    Just bought a cheap thermocouple meter on Amazon, not dropping $300 for a Fluke, will be interested to take some air temp measurements.

    Only reason you're measuring those exhaust temps is because you're putting the warm air from the MB and CPU AIO through it.  The delta-T is more like 10C.  My system (MB system temp) idles at 30C and gets up to 40C with the hybrid rad blowing over the MB at 400W+ board power.  That's with the GPU idling at 22C.  Try measuring in free air.  
     
    I'm running my rad fans intake at max speed now, at idle.  21C idle gpu, 27C system temp. After running at high power, then returning to idle, the GPU will typically be in the high 30's, which is a good indicator of the coolant temp since it's thermal mass is far higher than the GPU chip itself or the ~10W heat load of the GPU chip at idle.  Thus the coolant temp is rising by about 15C at high power, when the rad is fed plenty of fresh ambient air with fast push pull fans.  If the coolant is about 37C, there is no way the air dumping into the case is any higher than the low 30C's, worst case scenario, probably more like the high 20's with fast push pull fans.  Not a problem unless you're running your CPU at very high power levels, in that case you should tune your system accordingly.
     
    23C is with the PC more or less outside with ambient air around 0C.  Maybe like -3C since it idles 2C above ambient with max fans and it was idling at -1C after cooldown.  That's #5 in the US for a 3080 in Timespy GPU, btw.




    You know what they say about assuming stuff:

    Both CPU & GPU AIO radiators are exhaust on my setup.  So there is no delta between Ambient & my case temps, basically, internal temps in my case are 1-2C over ambient as evidenced by my GPU idling at 22-23C & RAM/chipset temps at idle being in the 24-26C range, motherboard VRMs are 26/28 respectively.
     
    It's pretty much an ideal setup, which most people's cases can't fit.  Both AIOs as exhaust, with 4 fans as intake that move quite a lot of air with very little noise (EK Vardars at around 60-70% depending on system load).
     
    With this setup, the GPU radiator is exhausting that warm of air during prolonged gaming sessions in games like Cyberpunk 2077 that really stress the GPU (34-41C depending on load, I have the game capped frame-rate wise so it goes lower as the load lessens in less stressful areas).
     
    For ideal GPU temps, it'd be best to straight up have the GPU AIO Radiator not in the case, but most people aren't gonna want to do that.  in a regular room temperature environment, that radiator is going to be spitting hot fire when under load, in comparison to most CPUs that people run these days.  Big socket AMD/Intel stuff like Threadripper or the larger socket Intel has is a different story of course, as those have heat outputs that rival the GPUs we're talking about, especially when overclocked.
     
    It will be interesting to see how much those exhaust temps go down once I get the Kingpin & it's a 3090 running on a 360mm radiator.

    lol - you lost all credibility you might've had with that one.  That makes zero difference with the amount of airflow in my case, temps do not change if the RGB is on or off, nor do temps change in any meaningful way if the radiators are NOT in the case.
    You just refuse to accept that having the GPU radiator as intake is a bad idea for the vast majority of people, I get it, but when you see the exhaust temps for yourself, maybe you'll wise up.  For people in regular cases, in regular use, with no special nothing, it's going to be much better for their system, if they only have room to mount one rad at the front & one up top, to have CPU as intake, and GPU as exhaust, unless their CPU actually draws more wattage than their GPU.  Period.  The CPU being intake is NOT going to raise temps enough to significantly effect your GPU clocks, because a CPU does not put out as much heat, and thereby does not heat up the radiator as much, as a GPU does.  This would also be evident in coolant temp I'd wager, but I don't have any way of checking that.
    I also literally just told you earlier in the thread my internal chipset/RAM/etc temps are within 1-3C of ambient air outside the case... so the fans having RGB on is definitely not a serious issue lol
     
    I'm not going to keep arguing the point when I know I'm right & you're mistaken, there is literally no point in arguing with someone that doesn't agree that intaking 34-41C air in to your case as opposed to the exhaust from a CPU radiator, which is going to be much MUCH cooler 99% of the time, is the better of the two options.
     
    If your motherboard has temp readouts for them, check your CPU VRM temperatures next time you're running full boar on your GPU, with that air being vented right on to them I'm sure they're nice & toasty.  That would also effect your RAM stability if you had B-Die chips that were OCed at all on your RAM, since B-Die typically loses stability once it goes above about 35C when running high clocks or super-tight timings... yet another reason having a GPU radiator as intake would be a bad idea especially for people trying to really push their system.

    Take it easy man, it's just a joke. 
     
    Regardless, nobody except you has two top mounted AIO's. 
     
    I agree your are correct about watching the internals temps.  My MOS never gets hot gaming because I'm gaming at 60FPS, but the system temp and ram is getting a bit toasty.  I'm going to up my front AIO fan speeds a bit, probably tie the pulling fans to system temp so they kick on full speed when system temp rises.

    Gpu top exhaust and cpu side exhaust. Gpu definitely exhaust much much hotter air, side or top mounted.(i tried both).

    I ran a 1080 Ti FTW3 Hybrid before for almost 2 years, that thing's lil' 120mm radiator acted as a space heater for my room at times during the winter, which was actually kind of nice.
    I'm really interested to see how much heat the Kingpin's 360mm radiator will be spitting with a decent OC, that extra fan's worth of heat dissipation should in theory at least make SOME difference, but it's also a question of how much that's going to be offset by higher voltage/clocks/heat coming out of the GPU as well.  Looking forward to it though, haven't had a Kingpin/Classified card since the GTX 285 Classified if I recall correctly... still have the EVBot, but that's sort of obsolete with the Classified software that allows you to adjust most settings in Windows on the Kingpin cards.
    Mounting is going to be fun until I get an open loop setup on my CPU, but I'm waiting to do that until I get an 11900K/eVGA Z590 upgrade in the next few months (I'll be getting the Z590 mostly via eVGA Bucks, which is why I'll be going Intel instead of AMD, it will in effect, be cheaper, by a lot).

    max temp is 54c at 2100MHZ
     
    does anyone know if i have to flash bios to hybrid, this is a kit, im still on ftw3 , rgb works, fans work, everything works

    So I did pick up a cheap thermocouple meter from Amazon and took a few quick readings with Furmark running at about 445W continuous, 3080 FTW3 top mount intake, mesh in place, about 2000 RPM fans average (stock plus A12's push pull).  This is a worse case scenario with higher GPU temps than normal, I've clocked 53C running Furmark in 20C air with max fans and am typically at 50C to 60C gaming.
     
    Ambient - 22C
    GPU chip - 64C (after like 10 minutes)
    Top gpu rad exhaust into case - 36C
    Back of card above filter caps - as above, it's blowing right on it
    Bottom of front mount CPU AIO exhaust into case - 28C
    Top intake air - 24C
     
     
    Pretty imprecise measurements, didn't tape down probes and run it with the case fully closed, just holding the probe for 15 seconds with the case mostly closed.   So yeah, the intake temps are kinda warm, but if I ran the gpu rad as exhaust, I'd go up by at least 5C on the chip.  I doubt the typical rad exhaust temps are any higher than the low 30's. Thinking about making a duct to direct the gpu rad air flow towards the rear exhaust fan.
