Id rather not hijack the thread by getting off point but I couldnt resist this one...

I'd be very interested to know what they are because I wouldn't have gone to all the trouble with my PSU?
Im interested to know what they are too. How did that improve the performance of your computer? What did you gain? Besides the satisfaction of successfully engineering something, I mean. The only point I was making is that I dont see what is to be gained by watercooling the PSU.
As for better/safer ways, I like my way which is just to take the fans out. The airflow it gets from air flowing through the case is all the airflow it needs. Or you could buy a fanless one, or one with fans that are essentially silent, or replace your existing fan(s) with quiet types. Hey, its your PSU so do what you want, but this is one item that I will not be watercooling.
Fhorst you could put a "space reserved for future use" sticker on it.

I'm glad everything turned out OK.
