The hybrid isn't adding anything new. Except for the FE cards, no 1070 card is limiting performance. Therefore, cooling the GPU won't improve results. If a card's speed drops at around 82C, then picking a hybrid cooler that runs at 52C offers no benefit compared to one that runs at 68C.
This is clearly incorrect. On Pascal architecture, the cooler a GPU uses, the more efficient it becomes and the better its performance. So, at standard voltages with a core at 80C, the max clock could be near 2100, but with stock voltage and a core at 25C, it might reach 2200+. These adjustments occur roughly every 10C. I've observed clock/voltage tweaks by the GPU when core temperatures drop to as low as 24C.
To achieve excellent core speeds on Pascal, you must rely on the voltage/frequency curve for overclocking, not just simple offsets...and always keep the GPU as cool as possible. Cooler performance is better. Maintaining a lower temperature enables impressive overclocks even at stock settings.
Begin with basic adjustments on the frequency/voltage chart. For example, I increased it using the curve and saw a crash to 2063mhz within two minutes under maximum voltage and power limits.
😛
With the voltage boosted to its limit and power capped, only a +65 offset was needed.
What does the curve look like? A screenshot would help. They're very precise about their setup, including voltages, clock speeds, and temperatures.
Should I adjust anything to improve my overclock?

My GPU reaches a maximum of 47C after 30 minutes in Unigine Heaven.
Beyond your target clock and voltage, everything should remain stable. The one I shared shows a jump after that point—especially the tick marks for 1075mv and 1081mv are too close to your set clock. Adjust them slightly lower, maybe around 2030.
Also, ensure the main voltage slider is at 100%. Otherwise, even if you set it higher, the voltage will cap at 1050mV and run at the corresponding clock on the frequency curve.
If you're struggling to start, try a very aggressive curve line for the clocks/voltages you plan to use. For instance:
why should everything after my target voltage stay flat when it can't exceed 1.093v?
By the way, I'll try this at home.
UPDATE!!!! IT WORKED!!! 2114mhz is now perfect for SSSh. Thank you! I just had to match all the others that were above 1.093v to the same clock and it worked!
This claim is completely false. Using the Pascal architecture, higher GPU temperatures actually improve efficiency, leading to better performance. At standard voltages and core speeds, the maximum clock could reach around 2100, but with stock voltage and a core temperature of 25°C, it would be about 2200 or more. However, no hybrid card has ever outperformed a high-quality air-cooled AIO card, while some have underperformed due to excessive VRM temperatures limiting overclocking.
Currently, I'm running Furmark at full tilt with a custom water cooling setup. The GPU temperatures are around 39°C. By adjusting pump and fan speeds in small steps, I've managed to keep them stable up to about 70°C. If you believe this, it's puzzling why performance stays so consistent despite these adjustments.
The basic idea is that throttling starts at around 82°C—see techpowerup reviews. There’s no throttling unless temperatures go beyond 82°C.
Why do I throttle at 42°C, 50°C, and 55°C? That’s a drop of about 13 MHz each time.
What are your VRM temperatures? How can I determine them? Only the GPU temperature is shown in the MSI Afterburner. :O

This is categorically untrue. With the Pascal architecture, the cooler the GPU runs, the more efficient it is, and the better it will perform. Which means, at stock voltages and core at 80c, the GPU max clock could be around 2100, but with stock voltage and the core at 25c, the max clock will be 2200+
And yet not a single hybrid card has ever shown a higher fps than an quality air cooled AIB card .... meanwhile some have shown worse due to higher VRM temps limiting the OC. Sitting here typing from a custom water cooled system with 5 x 140mm worth of radiator, twin pumps, 6 liquid temp sensors, optical temp sensor and twin water cooled GFX cards.
Running Furmark full tilt, GPU temps are 39C. By lowering pump speed and fan speed I have tested in approximately 5C increments up to 70C ... if what you say is true, how do you explain why performance remains exactly the same end to end ?
This is a simple concept. Throttling kicks in at 82C ... Look at techpowerup reviews. There is no throttling ... ever ... unless temps exceed 82C.
Thermal throttling starts at 82c, yes. But boost 3.0 will raise / lower voltages and frequencies every 10c or so to keep peak efficiency. At stock clocks, anything below 55c or so, you probably won't notice a difference. Start pushing up over 2150, and you will.
Pascal is all about temps, and those "thermal layers" that boost 3.0 will use to adjust voltage and frequency. On air, both of my GPUs would run at 2202 @ 1.093v with a really steep curve, but...they didn't run like 2202 should be running. Under water, and an normal ambients, they run 2214 @ 1.093v and do it very well. If I lower the ambient temps, they run 2240 @ 1.093v and do it very well. On air, they wouldn't have touched those clocks because the temps were too high....I've got runs done on a single card at 2278 @ 1.093v with coolant temps at 1c and the core temp never going above 22c.
Simple concept? Yes, it is quite simple, and you obviously don't get it. There's a TON of good info in this thread....I suggest you read it.

You can believe whatever you want, but......I've seen it. I've done it. Been playing this game for a while, and I'm telling you....you want higher clocks, lower the temps, because you'll never see good scores at higher clocks until you do.
JackNaylorPE tried HWiNFO but it didn't work for all cards. They mentioned never seeing an NVIDIA GPU with a VRM sensor before. Adding a sensor is possible, though. Some XSPC and similar options exist, but they aren't fully precise.

The hybrid isn't offering any benefits. Except for the FE cards, no 1070 card is limiting performance. Therefore, making the GPU cooler won't improve results. Performance drops when a card's efficiency starts at 82C, so picking a cooler that runs at 52C doesn't help compared to one at 68C.

Begin with a straightforward approach on the frequency/voltage chart. For example:
I successfully overclocked it, reaching 2063mhz within 2 minutes of a full power surge, using maximum voltage and power limits. Only a +65 offset was needed.
What did the curve display? Could you share a screenshot? They're very precise about their setup, voltages, clock speeds, and temperatures.
Are there any adjustments I should make for better overclocking?

My GPU consistently hits 47°C during Unigine Heaven for 30 minutes.
After setting the desired clock and voltage, everything else should remain stable. The image you shared suggests a target of 2075 at 1093mhz, but there was a sudden jump afterward—especially with tick marks for 1075mv and 1081mv too close to your set point. Adjust them slightly lower, maybe around 2030.
Also, ensure the main voltage slider is at 100%—otherwise, even if you set it higher, the voltage will cap at 1050mV and run at the corresponding clock on the curve.
If starting from scratch, try a very aggressive curve line for the clocks/voltages you aim for.
For instance:
Why should everything after my target voltage stay flat when it can't exceed 1.093V?
By the way, I'll test this tomorrow.
UPDATE!!!! IT WORKED!!! 2114mhz is now perfect with SSSh. THANK YOU! Just had to match all the previous high-VC cards that stayed above 1.093V.

To achieve top core speeds with Pascal, you need to follow the voltage/frequency curve for overclocking—not just random offsets... and always keep the GPU as cool as possible. Cooler GPUs can unlock amazing overclocks even at stock settings.
Start simple on the frequency/voltage chart. For example:
I ran a full overclock using the curve, reaching 2063mhz in under 2 minutes with maximum voltage and power limits. Only a +65 offset was needed.
What did you see on the curve? Would you mind sharing a screenshot? They're very detailed about their settings, voltages, clock speeds, and temps.

Once you've set the target clock and voltage, everything else should remain unchanged. The picture you provided indicates a goal of 2075 at 1093mhz, but there was a sudden jump afterward—especially with tick marks for 1075mv and 1081mv appearing too close to your target. Reduce them slightly, perhaps down to around 2030.
Additionally, make sure the main voltage slider is at 100%—otherwise, even if you adjust it higher, the voltage will cap at 1050mV and operate at the clock that matches that setting on the curve.
If you're struggling to start, try a very aggressive curve line for the clocks/voltages you're targeting.
Why should everything after my desired voltage be flat when it can't go higher than 1.093V?

My VRMs are operating at 42°C, GPUs (nVidia) at 44°C per HWiNFO... Radiator fans are spinning at just 550 rpm. After reviewing this, it seems close to what Guru3D observed with their thermal imaging, though I haven't compared thoroughly.
The sensor model is CHL8318/IRF ASP1212.
Some users have managed to get it working with AB... others haven't.
