It may be a lightweight, compared to the monster coolers that have been popping up, but it sure performs like a champion! Like a thoroughbred horse, the Thermalright SI-120 CPU cooler certainly shows its distinguished lineage. Find out why we love this cooler so much! Link : Thermalright SI-120 CPU Cooler Review!
Sorry to say, but this is definitely wrong for Papst Fans. All of them fit the Thermalright perfectly fine. I have the SI-120 since March of this year and use a Papst F2GLL 120mm fan (1200 rpm -> extremely silent and still more efficient than any solution I have ever had before). For users with more demanding setups the F2GL with 1600rpm might be the better solution. Maybe you should correct that in the review. Regards
Just as a bit of a follow-up...indeed I was mistaken about the Papst fans, my apologies. Here's an article by Madshrimps comparing several 120mm fans: http://www.madshrimps.be/?action=getarticle&number=2&artpage=1732&articID=421 The ones identified in the article as having the Thermalright-incompatible "rib type" construction include fans from GlobalWin, mCubed, as well as Yate Loon/Nexus.
