So this table fan set up is working stable. For a few hours during the day when temps are high outside the pcap changes to pcap temp and during late evening or so it reverts to pcap power.

The good this is the hashrate drops only ~2 MH/s now as compared to 20+ previously.

I am planning on ordering this Graphics Card Cooler, ~2000 RPM which should be hopefully good enough.
