Those heatpipes are 140mm long 11mm height and 3mm thickness from AliExpress. Small heat sinks are from vintage ATI video card and north bridge chips. I put thermal paste on the heatsink fin’s bottom then use silicon rtv to bonding them together.
Same bug with bios 3.4 of my x10slm-f, I rolled back to 3.3 bios. From bios release notes " Fixed failure of chipsec items BLE, BWP, and TCO SMI lock. " I think is the broken bios code related with PCH chipset.
