I have suspected this, but am not completely sure, which is why I
contacted VIA to ask this question about the motherboard. I am still
waiting for an answer. No online reviews has said anything about this.
The system is quite warm, but not burning hot. I have set a temperature
max threshold in the bios so any overheating worries should be out of the
way anyhow, right?
Thanks for your input.
