Here's a simple and quick index to find stuff in the forums or on the site ...
Using Google try this example in the search box
site:forums.procooling.com pump
This example works on other websites. This will even work with the Google images as well.
You can add more words like a regular search after the pump word example above. Or change the word pump to something like Zalman or Thermaltake or whatever you like.
Google will list the most active topics first. The fewer the words are for the search, the most up-to-date listing appears. So, it's a working balance on what and how to find things.
