Synthetic Temperature Test Results: *Ranked according to 100W small interface die test results.

Performance is very good for a relatively unknown heatsink such as the Coolink U1P2, but as we have seen that performance comes at a pretty high sound penalty. Both Thermalright heatsinks suffer the same fate incidently - loud fans make them almost impractical for home computer systems these days even though the thermal results are very lucrative.
