Remember that Unwinder said that he would never add support inside MSI Afterburner for multiple independent fans for cards like EVGA's iCX cards with Asynchronous fan technology? Unwinder even said that not only would he refuse to add support for EVGA's cards, but if MSI started using similar asynchronous fan control, Unwinder would decline to support it.

Well, it seems something has changed. Now that independent/asynchronous fans are now going to be showing up in reference NVIDIA designs, Unwinder has added support in Afterburner.

Unwinder
Hardware abstraction layer has been revamped to provide support for multiple independent fans per GPU due to introducing dual fan design on reference design NVIDIA GeForce RTX 20x0 series graphics cards and due to introducing native dual fan control in NVAPI. Both fans of NVIDIA GeForce RTX 20x0 can be monitored independently in hardware monitoring module now and can be controlled synchronically in manual mode

I am skeptical that this will add backwards support for EVGA's 10 series iCX cards, since the microcontroller and implementation is likely different.

*And then NVidia added asynchronous fans and unwinder ate his words and showed he will do what he is paid to do because money is more important than he wants to admit*

The love on this forum never ceases to amaze me. Here you go, from Unwinder:
 
There is no any “if MSI started using similar fan control”. Actually, MSI started using dual independent fan control a few years before iCX was born. It debuted with in TwinFrozer V cooling on . And yes, even for native MSI cards with independent fan controller we didn’t provide support for it in MSI Afterburner due to one simple reason: safety and reliability. There was no native support for secondary fan control in NVIDIA driver and NVAPI and in order to implement independent fan control on such MSI non-reference card, it was necessary to work with fan controller directly at low level, bypassing NVAPI fan control mechanisms and it was and is unsafe and unreliable approach. The same applied to iCX and their proprietary fan controller, which was invisible to NVAPI and could be programmed at low level only.

The reason of adding secondary fan control now with RTX series is simple and it is even documented in the release notes. Secondary programmable fan connector is assumed by reference PCB now and secondary fan control is now an official part of NVIDIA driver and NVAPI.

Yes, exactly. What's your point?

I like when features become adopted under an official standard. I think it is good.

squall-leonhart
his point is that evga's dual fan control won't work in afterburner.

As I said. The reference designs of the future should. And that's good for everyone.

 
Don't think this will happen.  Here is Unwinder's explanation...

As many EVGA Forums member like Afterburner, this is a good 20 series design change to know about.  The details of why is also a good read.
 
Thank you ty_ger07 for the post
 
Lets see if EVGA Precision X1 offers all we need for both previous & new GPU card designs
 
The patented EVGA iCX design & proprietary fan controller would challenge anyone wanting to make compatible software; without a business agreement to tackle the legal issues presented by revers engineering and licensing

I've always used afterburner but with the new 2080's, I'll be using the new Nvidia/EVGA Scanner.

But you won't use the new Nvidia/Afterburner Scanner? We'll see, huh?

I'll more than likely try both depending on which provides me more options.  Not really sure what you're implying.
 
Edit:  It appears you're taking issue with my description of Nvidia/EVGA Scanner.  From what I read, Nvidia AND EVGA collaborated on this new tool for the 20x0 launch.  Unwinder was unsure he would even include the scanner in Afterburner which is a MSI/Unwinder tool that works WITH Nvidia cards.  Perhaps I should have been more clear.  The jury's out and I won't know for sure which will work better for me until my cards arrive (hopefully around the first week of October). 

I don't know where you got the idea that the scanner was thanks to EVGA.  If by "collaborated" you mean that EVGA agreed to add NVIDIA's Scanner API into Precision, to the same degree, NVIDIA collaborated with MSI insomuch as Unwinder has tested NVIDIA's Scanner API and has said that he is incorporating it into MSI Afterburner.  At its root, the Scanner is built into NVIDIA's API and it is NVIDIA who should get the credit.  EVGA has done nothing to deserve credit for NVIDIA's Scanner API except for test it; just like it has also been tested in MSI Afterburner.
 
I think it is funny that you refer to Precision as "NVIDIA/EVGA", but refer to Afterburner as "MSI/Unwinder" which "works WITH NVIDIA cards".  Very bizarre.  Somehow EVGA works in conjunction with NVIDIA, but MSI just happens to work along side NVIDIA?  You have a strange perspective.  Both tools use the NVIDIA API, and should therefore be equals in any measurement of credit and credibility; except for the fact that one is buggy and the other is not, which makes Afterburner clearly the superior product, designed by the grandfather of GPU overclocking.

Dear forum visitors,

I shared my impressions about NVIDIA Scanner technology from software developers’s point of view. Now I’d like to post the impressions from end user and overclocker POV.
I was never a real fan of automated overclocking because the reliability was always the weakest spot of overclocking process automation. NVIDIA Scanner is not a revolution like many newsmakers are calling it simply because different forms of automatic overclocking already existed in both NVIDIA and AMD drivers for couple decades, if not more (for example NVIDIA had it inside since CoolBits era, AMD had it in Overdrive). However, it was more like a toy and marketing thing, ignored by serious overclockers because everybody used to the fact that traditionally it crashed much more than it actually worked. Different third party tools also tried to implement their own solutions for automating the process of overclocking (the best of them is excellent ATITool by my old good friend w1zzard), but reliability of result was also the key problem.
So I was skeptical about new NVIDIA Scanner too and had serious doubts on including it into MSI Afterburner. However, I changed my mind after trying it in action on my own system with MSI RTX 2080 Ventus card. Yes, it is not a revolution but it is an evolution of this technology for sure. During approximately 2 weeks of development, I run a few hundreds of automatic overclocking detection sessions. None of them resulted in a system crash during overclocking detection. None of them resulted in wrongly detecting abnormally high clocks as stable ones. The worst thing I could observe during automatic overclocking detection was GPU hang recovered during scanning process, and the scanner was always able to continue scanning after recovering GPU at software level and lower the clocks until finding stable result. In all cases it detected repeatable approximately +170MHz GPU overclocking of my system, resulting in GPU clock floating in 2050-2100MHz range during 3D applications runtime after applying such overclocking. Even for the worst case (i.e. potential system crash during overclocking detection) Scanner API contains the recovery mechanisms, meaning that you may simply click “Scan” one more time after rebooting the system and it will continue scanning from the point before crash. But I simply couldn’t even make it crash to test such case and emulated it by killing OC scanner process during automatic overclocking detection. So embedded NVIDIA workload and test algorithms used inside the Scanner API look really promising for me. And it will be interesting to read impressions of the rest overclockers and RTX 2080 card owners who try NVIDIA Scanner in action in nearest days/weeks.

Stay tuned!

Forgot to mention, you are absolutely correct about the scanner---I misread an article.  Scanner was developed by Nvidia and can be used by any overclocking program that wishes to implement it.  I was under the impression it was developed WITH EVGA, which is not the case.

Ok, cool.  That, and the "NVIDIA/EVGA" (who works directly with NVIDIA) vs "MSI/Unwinder" (who works along the side of NVIDIA like some sort of parasite), is what set me off.

From all the videos I have watched on overclocking the 20 series cards, most reviewers prefer EVGA's Precision X1 layout better then MSI's Afterburner. I think EVGA has a nice hit on the new Precision X1 utility.
