I suppose it doesn't have to be. How often does that happen? Would I have to worry about a nice liquid cooler leaking? Would a nice liquid cooler reduce the temps significantly better than the 212?
Most liquid cooling solutions come sealed from the factory. They do occasionally leak, though the chance of it is fairly low if you install it correctly. Corsair H80i is about as low end a solution as you want to go for liquid cooling...anything less is really equal to, or not as good as, the best air cooling solutions.
For air cooling...the Noctua NH-D14 or NH-C14 and the Cooler Master Hyper 212 EVO are great solutions. The Noctua options are typically a bit pricey comparatively to the 212 EVO, but they do cool better. That's not to say the 212 EVO is bad, it's one of the best cost effective solutions out there, and it currently sits atop my FX8350 personally. If you plan to OC a little, air is fine...you could probably get something like 4.0-4.2 GHz out of your 6100 on just air. If you want to OC much farther than that then you might want to go to liquid cooling.
Best of luck man!
