I have the 965 and the 880 right now, 880 which can't run the ram at the right speed, partiot 1.65v 1600 cl9, runs at either 1600 cl11 or 1333 cl9 (PGD38G1600ELK). Should be able to use AMP or AOD to get it right on the 890... I hope. I'm going to put the 1090 on that. So far the 965 is running pretty cool(ish) using my old am2's Arctic Freezer Pro 64 with it's 92mm fan and not cover quite the full cpu heat spreader lol. Idles low 30s and barely saw it touch 50 (51max). Stock ofc. I'm running an old corsair h50 120mm pwm fan as the exhaust behind it at around 800 rpm (65% speedfan) cuz the 880 doesnt seem to ever change the speed from the board header on it's own.
Is there a way to additional cool the vrms so I don't have to underclock the 1090? It would feel bad haha... I don't suppose there's anything like VRM spread spectrum on that board?
Yeah, while the GD65 was the cheaper board, the GD70 had more lanes for running higher than 2-way 16x SLI, plus the beefier looking VRM heatsink, that unfortunately harboured pretty meh VRMs.
I'll note that with boards that have sub-par VRM cooling, top-down blowers are better as they direct airflow over the VRMS, superior coolers which are typically front-back don't cover the VRMS, which then in-turn can lead to thermal throttling when pushed/OCd.
The issue with the GD70 isn't necessarily the lack of VRM cooling as such, like the 880 you could throw some aftermarket heatsinks on the VRMs if you get any throttling, the GD70 used poor quality MOSFETs, so they just blew. The GD65 had much better quality MOSFETS, as does the Gigabyte's 880, which has protection against them blowing, as well as better quality MOSFETs.
Obviously anything to keep the GD70's VRM cool is going to lead to less likelihood of them blowing under stress from the X6's consumption, but ultimately it's the consumption that is the cause of the blowouts, less than the cooling capacity itself.
For the record, I recommended undervolting
the X6 and keep it at stock clocks, not underclocking it. Undervolting it will cause it to pull less voltage through the MOSFETs and keep the thing in its entirety cooler. Disabling turbo and undervolting would be the only way I'd recommend using the Thuban on the GD70, you'll still get your uses for editing etc, while operating under much safer limits.
The X6 will be fine in the 880 overall, you may need some aftermarket heatsinks for the VRM (incase of throttling), but you will get throttling and nothing more severe with some OCing at least. And you'll be able to OC it much safer than on the GD70

also, just in BIOS often does not enable more advanced cpu power saving, so you often will have higher temperatures in BIOS compared to idling in windows.
you have nothing to worry about for 38c idle temp.
OS choice, pick whatever you feel more comfortable with. Win10 may have a little more overhead compared to W7, but nothing that would severely impact your experience (aside from forced updates and bad start menu / UI, but thats just my opinion)
While you're not entirely incorrect, that's only true for Intel, at least with this era. The Deneb era all were best kept under 55c for stability under load
, and a max operating temp of 62c IIRC. I think they actually cut out at something like 70c as their utter maximum, but you never really saw people operating these chips over 55-62c under load.
These chips typically idled between 26-32c in Windows (depending on factors), but yeah, as we both stated; 38c in BIOS isn't uncommon for reasons.
