Well, well, it would seem that the Thermal Integrations TI-V77L, is quickly being surrounded by Arkua heatsinks. The 6258 surprised us here by how much momentum it gained. An important thing to remember is that the downward exhaust flow plays a really big part in how these types of heatsinks actually perform.

If we were to remove the powerful fan that is on this cooler and drop in a standard 10mm thick fan you would see a pretty substantial difference in how the 6258 would perform. That's for another time though. The 60mm Arkua cooler is a very good small form factor performance cooler, and one worth considering if noise is not an issue for you.
