panda and ph2t, do you reckon the steel sink saps tranfered current to the motor via the casing? could an aluminium one eliminate the electrification of the metal parts in contact causing minute e.m. interference?
Steel? Or is it Copper…?
This reminds me of a previous thread with
Mr Lancer Evo (bless his missing soul).
Here:-
Metal Conductivity 10-6 cm-1 Ohm-1
Silver 0.63
Copper 0.596
Gold 0.452
Aluminium 0.377
Rhodium 0.211
Iridium 0.197
Tungsten 0.189
Zinc 0.166
Nickel 0.143
Ruthenium 0.137
Osmium 0.109
Iron 0.0993
Platinum 0.0966
Palladium 0.095
Tin 0.0917
Lead 0.0481
There’s a slight difference in conductivity, so if you want the
ultimate heatsink & current conductor you’d use Silver.
