theres 2 main ways a hg can fail, which either leaks all the time, or only leaks when the cooling system gets to pressure. not if your driving down the street vs racing.
I only offer suggestions based on experience.
Yours appears to be limited.
A casual "slap a couple of fans on it" is not much help, is it?
Read up a little more on the effect of rising temps on dissimilar materials that are bolted together.
