Oh, and
aphex... if your Lian-Li has the stock square stamped-aluminum grilles on the inboard sides of the fans, remove them, they're very restrictive. 42C case temperature isn't helping you there. Also, check the Thermalright-specific tips I posted
here and ensure that your heatsink's slid alllllllllllllll the way away from the raised solid-plastic end of the CPU socket. The second photo shows how, even with that done, there is only a miniscule amount of clearance between the base and the RSPECPUS. I realize your heatsink's base is finned, not solid like the SK-7 there, but the same principle applies.
