Being impressed up to this point I decided to open up the L&C to examine the entrails. The first thing that caught my eyes were the heatsinks. Older DEER models had a straight slab of aluminum extending from the resistors. That's it, just blocks of aluminum. That's why they heated up so much and required a higher output (and louder) fan: the surface area to volume ratio was very small so heat dissipation was greatly inhibited. The new model changes all that. There are a good deal of fins on each slab which, when coupled with a good intake grating, will cool down the PSU quite effectively. These aren't the best I've seen but are nevertheless a huge improvement over what I've had to deal with in the past.
