Mean Well RSP-500-15 Switching Power Supply
IT just arrived. Initial impressions: Much heavier than the cheapowatt 1/2" wider, 1/2 inch longer and almost 1/2 inch less High than cheapowatt. The casing is about 50 to 75% thicker aluminum t...

Yes noise is a big consideration. I already own the fans I will employ, in fact both are now installed on the Lid, the 60MM blowing inward over the internal finned heatsink.
As far as that rotron fan, I am not impressed. I look for noise made for air moved for how much current consumed.
In each and every published metric, the Variable speed Silverstone FM121 has it beat with 110 CFM at 39.5 dba max and consumes just 0.4 amps at max speed.
I say max speed because it comes with a tiny 10K ohm potentiometer to change fan speeds from 33cfm to 110cfm and anywhere inbetween.

Yes it is a 21$ fan, yes one could get a lot of fast louder fans that consume more current for 21$, and blow away an Aztec's flatulence.
When a better mid range 12v 120MM fan comes out, I'll own that too, but for versatility and durability, this fan wins.
Mostly When the MW unit is generating lots of heat in my usage, I am going to have the cabinet door open, so I can read the GTpower meter's readings. Since I'll only be charging one battery, the timespan it will be generating lots of heat will be limited to around 2 hours anyway. My 12 volts loads would rarely exceed 15 amps, and the unit runs cool at these outputs.
The cabinet is ventilated too. There is a large louvered vent for the fridge, and there is a 80MM fan exhausting the cabinet. There is a removable insulated partition between fridge and electrical cabinet. In wintertime I close the vent and send preheated condenser air into electrical portion of cabinet whose fan exhausts it to vehicle interior. In summertime I install the partition so condenser air is forced out the louvered vent by a single Noctua Nf-f12.
After cutting the opening in the steel lid for the 60MM Noctua, I started fitting heatsinks into the exterior case recesses adjacent to the transistors. Lots of filing to get them to mate nicely and some drilling so that the screws behind are still accessible. Any gaps will have to be filled with Arctic Silver thermal adhesive. Got the starboard side 60% done
New GTpower meter arrived today. It's going to get the 8 gauge treatment too, with some 45A powerpoles
Still contemplating the installation of 10 turn trim pot. Kind of reluctant to break the threadlocker on the flatbars pulling transistors tight to casing, but got a hankering to finger twist my voltage.
