it does, a xigmatek hdt-s1283, with a fan on it, along with 2 intake fans and 2 exhaust fans. i thought the temps seemed a little high when i first installed it (couple years ago now) so i actually removed the heatsink, cleaned the surface and re-applied the thermal paste i dont remember what the temps were but dont think they were this high
In my case, my computers are in an air conditioned environment. If the ambient air temp is, say, 20 C, my OC'd Q6600 under load runs 61 - 66 C. That's about 45 C over ambient. If the A/C dies and my room temp rises 15 C, so will my load temps.
