Been nursing my TMIV's since April.  Thankfully, they're still going strong more or less.

My cooling system went bad on one board a couple of weeks back.  So I ordered two of the Corsair H60s as per a previous post in this thread.  Now I'm back in business.  It was a bit tricky getting the radiators in the box, but the method of sandwiching the fan between the two radiators seems to work just fine.

Thought I'd post as such.
