Pros: I liked the overall construction and mounting approach, a simple direct motherboard mount. .

Cons: Once I carefully checked the instructions diagrams and found the appropriate standoffs for the am3+ versions mounting is simple ; ONLY if you use the original backplate. ! I had to use rubber spacers with. In a nutshell the included plate DOES NOT match the screw threads Mostly I am not completely satisfied with fan itself the verison shown here on Newwegg is outdated. I received the newer one 2.1 as per Silvstone's website that shows the fan frame being black, not blue, partly the reason I bought this item the blades are white . One major change to the fan is lowest rpm is a NOISY 1600! Newegg states 1000 rpm and upwards. At a size of 120mm the fan should not start @ 1600 rpm when sitting idle especially with heatsink this size. I will be using an extra COOLERMASTER fan instead with a more respectfull 800 to 2200 speed variance don't think much of silicone mounts. They are PAIN to attach the fan frame.

Overall Review: If I had known this all BEFORE I chose this item, definitely would have chose a HYPER 212. I have that one in another build for several years and no issues. What's the idea for this horrible OVER pricing of AR01. I paid 45.00$ not 90.00+ ? Have noticed this with other items as well. Barely WORTH 45$ for my own reasons. Depending on one's needs this may item may work for you
