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, Thing just pumped 40 amps for 45 minutes, now tapering.
Sensor Got up to 109f, but hit 115f in 10 seconds holding my hand in front of 60MM intake fan and dropped back down to 109f in another 30 seconds with hand removed
Loud meanwell switched Fan came on at 102.4F, turned off at 98.6f and when amps tapered to 31 at 74.3f ambient.
IR gun not precise enough to hit any individual transistor leg, And it is buttoned back up with lid in place so hitting any leg with it is not going to happen.
These temps do not appear excessive. Any more heatsinking and ventilation necessary?.
90AH AGM Battery temperature has risen 14 degrees F in less than an hour at ~32 to 42 amps. varying loads on battery/ PS during charging.
battery Now at 84.9 degrees. Ambient 74.3. Rising quickly during CV amp tapering. Is holding 14.5
Heatsink temp 93.2F at 22.8 amps total output.
In photos above, one can see the longer wider transistor with blue glob on screw thread, and barely see the heatsink I attached to casing on other side. This heatsink gets the hottest according to my IR gun, and also as it rests on my cabinet door, is on bottom making heatsink less effective.
Perhaps I am not done with adding fans. This overkill anal retentive nature of mine can be frustrating.
