Did I miss the original kp hc queue or has it not happened at all yet.

Did I miss the original kp hc queue or has it not happened at all yet.

the KPE HC does not yet have a queue.

I am pretty much solely focused on the KPE Hydro Copper. But I am getting so desperate that almost any HC will do at this point.

I'm thinking of asking my aunt to put 900 towards a 3090 hc kp instead of the 3080 hc and explaining to her that I can make like 10 bucks a day mining, plus my current hours means I will easily be able to spare 100 every two weeks from check
Meaning I can pay other 1200 of card in like two months lol

It's for my bday present lol

btw my bday was in Jan, been patiently waiting for my present lol

Does anyone know if the hybrid kit for 3080 will fit in a Fractal Design Define 7? I would like to place the radiator on the top of the case in a push/pull.
I know the case can hold the radiator size, just wondering tube length.

I have the Define Nano S (ITX version) and it fits just fine, but you have to look out for ram clearance on the fans.  I had to run a slim fan to make it fit.

The noise reduction is a bi-product - the main advantage is lower temps leading to higher actual boost clocks.
I.E. your offset if you do regular offset OCing will result in higher clocks by default, because of the way NVidia's boosting works, with lower load temps.  Every 5 or so Celsius lower in load temp results in another step up in MHz allowed by the boost bin, basically - and when you're talking about load temps in the 60s-70sC with air cooled cards, vs 40s-50sC on hybrid cooled cards, that can be quite a sizeable difference.
 
I've always ran Undervolt/OCs on both my previous air-cooled cards, as well as all the Hybrid cards I've owned (1080 Ti FTW3, 2070 Super, 3090 FTW3 & now the Kingpin), so I can't exactly state how much of a difference it makes persay - I prefer the slightly lower power draw & temperatures of an Undervolt/OC to pushing as high as I can get with full voltage... not to mention 2160MHz core @ 1068mV is pretty close to as high as most people can push their Kingpins on stock voltage for daily-use settings, and it also runs cooler as a result of not going up in to the 1075mV-1100mV range that stock voltage can hit.

Does the hybrid actually allow a good amount of overclocking over air?
 
Or is it more for sound reduction and longevity?

Depends on the card. There doesn't seem to be a whole lot of head room, power-wise, in the 3080 XC3 Ultra. Mine runs whisper quiet on a linear fan curve that starts at 30% at 40C and ramps up to 100% at 80C+ but the card almost never climbs over 60C. The max OC I can put on it with 108% power is +88 GPU and about +750 memory. It never throttles for temperature, only for power starvation at the VRM. I'd consider stepping up to a FTW3+hybrid but that's about $300 when you factor in the FTW3 hybrid cooler that I'd need and me having purchased the XC3 before the price increase, just to squeeze some slightly better numbers out of the silicon.
 
TL;dr XC3 Hybrid performs well and quietly. FTW3 has a much more eager group of enthusiasts helping make sure the BIOS updates get them the right balance of power and cooling for some serious water-cooled OC boosts.
 
VRAM cooling factors into this as well--at least some of the VRAM chips have indirect contact with the cooling block. The other VRAM on the back side gets some thermal pads to help it sink heat to the backplate.
 

No 3080 FTW3 Hybrid movement for quite some time :(

RE-BAR 450W FTW3 HYBRID BIOS:

Are you guys still at 450w nominal max power limit with the new bios (gpu-z read)?  Any noticeable changes in power draw?

i just checked techpower up bios database and apparently this bios was submitted there in december 2020 so its NOT new....anyway everything seems like it was before. 450W max draw, idle around 100W. max fan speed 40%... I have converted HYBRID with hybrid bios
 
wonder if @EVGA_Jacbob  can comment on this. I was expecting new bios and not 3months old.

If on HYBRID BIOS use this update, seems error in Precision that it does not detect if HYBRID BIOS was installed. https://cdn.evga.com/bios/30Series/3898_OC_450W.zip

 
^^That's the OC switch position bios.
 
This may or may not be the normal switch/fans, Re-Bar bios.  Dated 3/23/21:

Well, yeah.
They can get more money for the other versions, and wait until the grandfathered pricing for the 3888's expires and jack them up too.

I think my hybrid (or the card?) is a dud on the 3090 FTW3, 30c idle (40c when clock speeds jump) up to 70c+ load. Mem temps are about 10c higher than core idle, haven't seen it's load temps yet. Gone in and out of the hybrid to remount and reapply thermal paste carefully dozens of times with little to no changes in temperatures and fasting screws in different tensions. Radiator mounted top exhaust in Lian Li 011 Dynamic case. Normal bios, normal clocks and voltage.

Interesting.  What is your full case fan compliment, speeds, locations, etc, especially under GPU load?  Hybrid ran fan speeds?  Cpu Cooler and load?  Case filter?
 
After running at full load for 10 minutes (@70C?), when you remove the load, what does the GPU temp fall to after about 5-10 seconds?
 
What is your ambient air temps?
 
If you answer these questions, we will likely be able to highlight the cause of your higher temps. 
 
My 3080 FTW3 Hybrid runs about 53C under sustained 445W Furmark load with max fans.  Push pull (stock plus A12's, sealed to rad) top exhaust and a whack ton of intaking fans. 23C idle in 20C ambient.
 
 

I've got 3 bottom intake Dark Rock Pure Wings 2 going at about 800rpm and 1300-1400rpm load and Kraken X52 intake radiator on the side for the CPU at 50% (On the advice that CPU intake aides in supplying cool air with this setup), can't get RPM readings on it for some reason for now. Dust filter at top exhaust and bottom. Hybrid ramps up 100% at 2991rpm with the memory fan at 791rpm during load. Maxing all fan speeds makes no change, hot air exhausts from the radiator. After testing temps drop like a hard rock down to low 40s and gets down to idle temps within less than 10 seconds. Ambient air is 20c currently, low humidity.
Testing with open case and removing filters also show minimal change, maybe 1c difference if that.

What are your MEM and PWR temps?
Edit: Added photos, idle is with no fan spinning on card and 760rpm, 100% on card fan reduces temperatures to 35c ish.

kevinc313
The fan on the card is for the VRMs, I'd try about 75% or 2000RPM.  Make EXTRA sure you aren't running the rad fans at ~800RPM, radiator fans should be over 1500rpm under load, preferably about 2000RPM.
 
Your coolant - card delta is about 27C (=70C-43C) which isn't that great.  Both my 3080 and 2080Ti were in the high teens, like drop to 38C after operating at 55C.
 
It takes my card minutes to cool back down to 23C idle, but I'm idling at 210mhz low power.  
 

Yeah the radiator fans are well over 2500rpm as soon as load hits automatically, not set manually. The absolute lowest idle I can get to is 33c and it gets there almost instantly after ending load test.
I'm RMAing both the card and hybrid for EVGA to check out, they also believe it's higher than it should be.
