There is something I've been a little confused about for a while now and I was hoping someone here could help me out. Anandtech has been testing several coolers lately and I've noticed an interesting phenomena: The best cooling device at lower clocks (even at load) can't always reach the highest stable clocks. I think of cooling as linear and if they are using a chip capable of going up into the 3.94 GHz range I would think that any cooler that can cool the CPU sufficently would be able to reach at least that clock. For instance the Arctic Freezer 7 can keep the CPU to 37 degrees at 3.8, where the highest clocking cooler (the Turniq Tower 120) only keeps the CPU to 39 degrees. Anyone have an answer? I'd be very interested to understand this. Thanks in advance.
