The power output of one of my 5 watt CNI 532 DPSS modules is fading badly and I was wondering who sells reliable 5W+ 520 modules. I'm going to need the module ASAP. Thanks.

No one so far IIRC...
The highest I've seen is a 1Watt 520nm LD.

Always in stock and ready to ship....
Subsidary:-Pharma Electronic Solutions
Lightspace sells 520nm modules
Kvant sells 520nm modules ,
Both reliable from my experience
Don’t bother replacing that CNI 5 watt 532, they are crap and don’t last more than a few hundred hours

Got that right. Mine only lasted ~300 hours.
... most of the cheap diode-modules are running above specs and with drivers, that generates short high current peaks when switching ON/OFF (or TTL-modulating), what's killing the diodes pretty fast, even when running "at specs".
I'm using high power diodes with currents of up to 30 Amps for material processing; and developing my own drivers, to get them lasting longer than given from the vendors -- if a diode is used within specs, at 100 percent of the recommended current, and with a "perfect" (spike-free) driver, it can last for let's say 10000 hours ... but when driving it stictly with 10 percents lower max. currents than recommended, this will double the lifetime
But on the other side -- overdriving the diode (like in most actual modules) will reduce the lifetime drastically! ... and short overcurrent peaks when switching or TTL-modulating (especially when switching OFF) even more ...
