I agree with ebastler.  The fan in my Korad is not noisy at all.  If you do need to replace it, I put a Noctua NF-A6x25 FLX in my [formerly noisy] Rigol DS1052E oscilloscope and it is pleasantly quiet.  I'm not saying it fits the Korad PS (I don't know), but I'm at least recommending the brand.

@eevblogger88, one more comment. I just saw from your other posts that you are in the process of setting up an electronics bench from scratch, intending to do repair work on phones and computers.

Do you plan to do that for money, by repairing for others and/or making Youtube videos? If so, have you been able to gain some practical experience yet? Watching Youtube videos by Rossman and Northridgefix and buying a bunch of equipment is not the best approach to become productive, I think.

E.g. it would be so much better to try working with a binocular microscope vs. a video microscope yourself, rather than listening to what the guy at Northridgefix prefers. (I don't doubt he knows what he is doing, but what works for you will strongly depend on personal preference and experience!)

If you have not done so yet, and have any opportunity to make it happen, I would recommend that you look for an internship in a repair shop.

Early KA3005P units like mine at home have a very different heatsink from later units, one that causes far more turbulent airflow. Replacing the fan in those (which I did in mine) does improve noise, but not by very much. It’s my understanding that the new heatsink design is much quieter.
I have a recent KA3005D at work and it’s noticeably quieter.

Since this thread is about UI changes, I want the memory buttons and the indicators (LEDs) in the same bloody place.  Either put the LED right next to the button, or inside the button.

Have 2 re-badged versions of these.   One is very finicky in flicking voltage values up down when using the wheel to adjust voltage (adjst voltage of current).   It can flick up/down wildly with minor encoder wheel movement.   Its is extremely annoying.     Mainly noted when adjusting points of a volt/current.

I have 2 of them...the other is ok but a little twitchy like the first.

Its as if its not counting the encoder correctly or makes multiple jumps on one encoder click.  Going to have to try fix this....real PITA.
