Hmm haven't had any problems like this and its been over a month. I don't see why it would be a problem, the pumps have only a single moving part and its an impeller. Email Eheim and ask, their support is great about that sort of thing.
As for pics, check here.

Second from the top. Yeah I know it isn't procooling, but I'm waiting until I get my new tubing and GPU block before I post the pics here. My current setup is downright sloppy.
