Lets try to keep the thread sober and based on fact - shall we

According to several roadmaps and the International Technology Roadmap for Semiconductors (ITRS), high performance ICs will dissipate 200W within the next three years (source BCC, Inc). Our users normally uses their cooling systems for quite some years, so we consider it the best choice.

Yes a compressor designed for R404a/R507 will be more noisy than a compressor designed for R134a. However when failure accurs to the valve system on the R134a, the R507 compressor will still hum along although a bit louder

According to own experiences while working as an engineer at Danfos in Flensburg Germany, where the NL11F is made, it will fail. Maybe not in the warranty period, but it will fail. Danfoss will void all warranty with the use of R404a on an NL11F. Instead of discussing this in a forum, just call Danfoss.
