Inside the new Korad KA3305P linear PSU

I wonder what the effect would be to stick a nice big aluminium CPU heatsink right on the transformer core? Maybe even with it's own fan? Would it help keep the transformer cooler? Would it somehow interfere with the magnetic flux of the core?

bitseeker:
It might help, just depends how quickly the heat can be dissipated. For a large transformer, the surface may not overheat, but the interior still might.

Kleinstein:
The heat in the transformer comes mainly from the windings. So cooling the core will help a littel, but not that much.
At least it will not interferre with the normal magentic flux. However still some care may be needed, not to cause eddy currents because of eletrical contact to more than one sheet of the core.

Update: it's first thing Monday morning and the guy who is handling this must be back from his vacation because he sent me a message that they are packaging up a replacement board with instructions on swapping it out and it will be in the mail in the next day or two.

bitseeker:
Although issues have come up with Korad power supplies, the manufacturer is quite fast with fixes. Korad and SRA are pretty responsive and flexible with rectification too, which is good to see. If I didn't already have plenty of vintage power supplies, I'd probably get one of these triple-channel ones.
