, in this case I doubt it's an issue that the single phase isn't covered. The fact that one phase doesn't have a heatsink but the other three do doesn't really mean much, it could even mean there isn't much need for a heatsink b/c of the low power draw of Skylake CPUs.
Good to know.
The only real way to see how it works is to try haha, I think you will be able to get a decent overclock out of the board, the board probably does have limits in place so you can't break the VRM, that being said if you keep constant airflow over the area you will be better off most of the time.
I did overclock, I got up to 4.6GHz at <1.4V. 4.7GHz would require more than 1.45V so I'm not gonna go there. But 4.6 seems safer now that we know what the VRM consists of! And it (hopefully) helps that I replaced the thermal tape with Alphacool 11W/mk.
I also delidded the CPU (Coollab Liquid Pro, lid back on, MX-4 on top). I didn't have
to delid because my temps were more than fine even before delidding. But it was still fun and worth it:Delid photos (Click to show)
4.5GHz @ 1.344V, Prime95 27.7 SmallFFT 10 min
Before -- 71-69-66-69 °C
After ---- 59-58-57-58 °C
I can run a slightly quieter CPU fan profile while keeping much lower temps.
The MOSFETs are pretty solid and their arrangement is good (2L1H).
Thanks for all the help!Edited by lehtv - 10/5/15 at 1:49am
