It would be time to replace it.
The quote above is from July 3, in response to concerns I had over possible leakage. I should have taken this advice, and just kept the Silver Arrow I had in hand as a "just in case" measure.
Today my video card stopped working. 8 beeps meant video RAM. I thought it was odd for that to just suddenly happen. Card is only a year and 1 month into warranty, so I was looking into the possibility of sending it in. Then I grabbed the card.
Wet. When I looked further, it was really wet the nearer you got to the pins. Investigate possible sources and find there can only be one. Sure enough, the bottom of my pump is leaking that fluid-esque substance. So I say farewell to my H50. It lasted 1 year 8 months. Let me guess... these things only have 1 year warranty? lol
