Hmm to me water cooling is over exaggerated for my Workstation needs, it's nice to see it with them OC setups though, it's enjoyable to look at and educate to a certain point as cable management goes, very handy
But for me it's no need, my CPU's are server based, they don't go beyond the load temps of 37 to 38C and I am just using simple ASUS Triton 70 HSF's on them.
I can get the temps down to 27C if I go Noctua's, but it's still no where near the threshold temps, which are 80C+ heh, so I am not even worried about that and it saves me much lesser hassle

My main system is 3 years and 4 months old now and so far it needs no more upgrades.
