The Evercool Transformer 4 (HPJ-12025) performed fairly well in testing, chasing after the similar, albeit single-fanned, Titan Fenrir by a couple degrees in each test. The hardware needed to install the Transformer 4 was included and the instructions were somewhat difficult to read or understand due to typos and poor grammar, but it had plenty of pictures that made it easy to infer the general idea. The art and design of the packaging looks good, as does the heat sink itself. The included thermal paste worked well enough, and felt similar to Shin-Etsu. The performance with the CPU overclocked allowed for more headroom and beat the stock Intel offering hands down. During testing, the fans operated very quietly and kept temperatures in the safe-zone. Clearance and size weren't an issue with my setup, but there were a few close calls; users should make sure that this heat sink will fit their system before purchasing.
