It does not matter that much. You could take the lowest frequency of the default curve. The most important frequency to optimize for is the highest, because that's where the voltage, power, and temperatures will be the highest too.

If you had a lot of time you could pick all the frequencies your card supports, and find the lowest stable voltage for each. Since you probably don't want to spend that long you could pick a few different frequencies (maybe just 1740 MHz and ~1300 MHz or whichever lowest frequency you want) and...

Thanks a lot for your reply @PLLovervoltage! Could you please explain the difference between the method I described and undervolting? Since I am reducing the voltage at each frequency on the curve I thought it did count as undervolting. But I'd love to hear the difference, and also about the...

Hi team, I am new to GPU undervolting and experimenting with MSI Afterburner on a GTX 1060. I'm mostly interested in reducing temperatures. I understand that most people adjust the frequency/voltage curve. They keep the same max frequency, but lower the associated voltage. There are many...

Thanks for the helpful replies @bichael and @NateDawg72. It survived 18h at 115mV through a combination of stress tests, gaming, and browsing. I happen to have time now where stability is not critical, so I will keep backing off progressively. But I think both your replies are spot on and it'll...

Hi team, I'm in the process of undervolting an i7-8700 (non-K) in a Dan A4 SFX. I found a voltage I cannot go below, and I'm now reducing the offset back to a level where the system is stable. I run Prime95 but it does not find any error and the system freezes instead. Below are my times to...

Hi team, Just sharing a few pics I took yesterday. Config: Dan A4 SFX v3, i7-8700, Noctua L9i (with fan duct), MSI 1060 6GT. Before snapping I let Prime95 and Furmark generate heat for 30 minutes with the case closed. The CPU long term power limit was set to 65W. The components temperature...

I did not order online: there is a shop not far away from where I live. I picked it up, so USD 15 does not include shipping. I don't know the usual prices online, but I can't imagine it to be much more expensive. If you can wait I expect there are cheap places in Shenzhen too.

Sorry to be late to the party. The files to create the fan duct in the photo are now available at https://github.com/marcv81/l9i-fan-duct. Nice design @el01. My comments are on the resource thread https://smallformfactor.net/forum/threads/92mm-fan-duct.9290/.

Look nice! Would be awesome if you had a photo of it mounted; actually I'm not sure I understand your installation instructions. The C7 is always a bit tricky as the fan clips in and does not have screw holes. I have not tried but the spacing between the mounting holes should make it compatible...

Thanks for your reply @Narwhal. Now I see where you're coming from. I'm not sure what the TDP means. My GTX 1060 has a 120W TDP and never ever exceeds it. The i7-8700 on the other hand happily exceeds its TDP under heavy loads. I take the processor TDP as an indication for OEMs and system...

The files can now be found here: https://github.com/marcv81/l9i-fan-duct.

@sam_no90, @Narwhal, please correct me if I'm wrong but as far as I understand the CPU clock speed should not matter. I set the TDP limit to 65W; the chipset adjusts the CPU clock down to make the estimated power consumption fit within the desired limit. As far as I remember the CPU clock was in...

I used an i7-8700 with the long term power limit set to 65W. For a fair thermal comparison the fans were forced to their maximum speed. I concede that this test is not representative of real use. With the default fan curve both the C7 and the L9i are virtually silent when browsing. When gaming...

Hi team, I considered the C7 and the L9i for a DAN A4 SFX v3 build. I didn't know which one I would prefer so I tried both. I'm sharing my findings in case it helps someone. TL;DR: If you can tolerate the weird fan noise get the C7. Otherwise get the L9i but make a fan duct. Temperature I...
