  1. Sounds like an unbalanced fan, fan motor mounting loose, bearing slop, or mounting frame not stiff enough so it flexes , at least to me. If the mounts have “rubber” vibration absorbing pieces, one could be damaged or missing. All blowers, fans, have “critical” rotational speeds where the fan should not operate for long due to the natural resonance or they will damage bearings at minimum. Used to work with GE frame 5 gas turbines. It was always fun starting them up as you had to bypass vibration interlocks and get through the critical speeds as fast as possible to minimize wear. occasionally, the startup firing would stall a bit and the gas turbine would not accelerate quick enough. Big pucker. Just because you cannot hear the vibration at other speeds doesn’t mean the imbalance is not there. Likely have to replace the fan blades or the whole fan plus motor plus mounts depending on how they do the parts. I would vote for replacing the whole assembly since it could also be driven by slop in the bearings. Maybe send the recording to Malaysia ?
  2. The words “gaming” and “TUF” raise the tariff anywhere. maybe the -P or B motherboards have enough video out support ? or look at the workstation motherboard. Usually as or more reliable / higher quality components, particularly on power.
  3. With the breaker “off” and confirming no voltage on either house wire before disconnecting lamp from the house wiring ?
  4. For basic, relatively inexpensive, accommodations in the middle of the city, try the YWCA Fort Canning historic hotel on Orchard Rd near the Dhoby Ghaut MRT station. Roof top pool available. Convenient access via MRT to airport and major tourist sites. Stayed there with the wife and 3 kiddos for a few days. Saw the sights. It was good enough as we were out and about most of the time.
  5. I think this question was missed above - “ EDIT Is the supply on the poles fed from the main building box or is it the incoming supply from the meter?? “ Quote
