Products with ISO certified meant the manufacturers are the pro-active type in making sure the products are produced with consistency in both materials used and workmanship. I found this prestige marking on the package.



Introduction:

Arctic Cooling received thumbs up with VGA Silencer from every product review, and the product lines covering CPU, VGA coolers, fans and thermal pastes are distributed by SCYTHE world wide. We are taking a closer look at the Super Silent 4Pro L CPU cooler aimed at Socket 478 application. The all aluminum is rare for a new cooler as many have migrated into all copper or aluminum/copper hybrid.




The 4 individual spring loaded clips secured to the four corners of the HSF retention bracket with positive feel and no fuss installation.
