it is sometimes worthwhile to distinguish between sellers of components, and manufacturers of devices
one is not accountable for performance, the other is

Sorry d00de but I don't have the faintest?
When and where did I otu the two of them in the same bag?
I know what Swiftech does and I am using Swiftech products exclusively atm.
Steel (or steel alloy) bolts have lower conductivity than copper indeed but as you perfectly know structural redundancy of a bolt is MASSIVE and wasteful compared to quite elegant tensile wire fastening solution not to mention expotential decrease in cross sectional area largely eliminating parasitic thermal gradient energy migration
.
I does require more workman hours (marginally more if mass produced and appropriate assembly procedure is applied) but I think it is worjth it especially with the dawn of ~300watt TEC modules and Scotties
and I know you do not need to pric your ears snce you got a finger in almost every pie
EDIT: and I know that TECs bigger than 226 watters are older than most members of this forum
