Thanks,
Bonk.
It's
DEMCiflex white round 140mm dust filter.
Seen it in one of the LZ7 black builds. This community is really helpful )
So I'll try to be helpful, too, and start with some
tuning experience (to be edited):
Motherboard: Asrock Fatality ITX, intel 8700 undervolted in BIOS -0.09v, VCCIO and VCCSA to 1.15, Gigabyte Aorus 1080 ITX.
While
browsing (balanced Win10 profile): CPU stays under 3000 Mhz, total power use - under 40W, CPU&GPU temps - under 35C.
Browsing (CPU and PSU in passive mode) - all the same with temps under 45C.
What is the difference between
CPU power profiles in Win10: 5% - idle CPU stays under 2000 MHz, consuming 15W. 100% - idle CPU stays at 4300 Mhz, consuming 20W.
Stress Testing: 4300 Mhz (6 cores), total consumption stays under 250W, CPU&GPU temps under 70C.
While 8700 is not for overclocking, it’s possible to upgrade its build-in overclock:
Turbo Boost (long OC) up from 65W, and
Max TurboBoost (short ultraOC) up from 122W, its
duration from 25 sec. up to 96 sec. Yes, 8700 base freq is 3200, so this will allow you to stay at build-in OC 4300/4600(1 core)
longer and safer. This is done in
Intel XTU utility.
In general, overclocking to 5000Mhz means something like +10% faster and +100% more power consumption, not really efficient.
Fan settings:
1. Case fan to 0% until CPU 50C - it will still rotate, but inaudibly.
2. CPU fan to 30% until CPU 50C - Noctua NH-L12s is so silent, you can't hear it until about 32%, so let it work instead of other fans.
3. GPU fan - Gigabyte ITX cards work fine by themselves, going to passive when they can.
4. PSU fan - if it's noisy, just remove it - Noctua NH-L12s heatsink will absord the heat from PSU body and cool it with silent CPU fan.
