2018 14" Lenovo Thinkpad T480s [8th,4C,U] + GTX 1650 @16Gbps-TB3 (AKITiO Node Lite) + Win10 [spud_egpu]

eGPU hardware

Akitio Node Lite, MSI GTX 1650 Ventus XS OC 4G, Rear vent only exhaust taping with Aluminum tape from HomeDepot,  Removal of Node Lite fan, 120W external PS ( https://www.amazon.com/gp/product/B07JQ6JN2J/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1 ) 

Note: GPU in Node Lite runs cooler if taped for rear exhaust only and Node Lite Fan is removed as reported elsewhere.  I found a ~5C lower operating temperature post OC with taping and fan removal.  Under FurMark load testing,  Stock configured ~80C , as Taped and Fan removed, ~75C, Taped with Fan ~82C.  Was this due to sig. more airflow as std fan is very close to MSI 1650 fan case?

Note: Carefully taped with aluminum heating tape! Some insulation on a few surface components near back bottom at card connector.  Alum. dots on fans are butyl rubber roofing patch tape.  It seemed to damp some of the remaining fan HF noise.

Installation steps 

MSI GTX 1650 XS Ventus OC 4G card fits into std stock Node Lite. GPU runs cooler if taped for external 'exhaust only' and Node Lite Fan is removed. Node Lite itself is way over designed and could have 1-3 lbs removed by cutting away unused steel GPU holder sheet metal weight. I was too lazy to do this. (steel really? should be plastic)

Decided on Amazon sold 120W PS with 5.5x2.5mm barrel connector (link above).  This meets the 10A max current spec of the Node Lite barrel connector.

Thanks for all the info on eGPU.io.  In ~2 years truly portable eGPU's should be std products at reasonable prices, but while they are not this site is very helpful.
