I bought it to replace the stock cooler for Intel socket 775.
Simply a tragedy, at least on my motherboard.
The base of the cooler barely fits, but the main body doesn't fit at all because the latch that attaches to the base requires some extra space to latch onto and it was sitting on top of the chip cooler of the motherboard.
I had to remove it to install it, and while the system was working, the performance of the cooler was good, but of course, after a while, the motherboard chip overheated and the computer froze, so I had to reinstall the old cooler.
Money wasted, maybe I will use it in the future on another PC, if it fits, of course.
I can't understand how a reputable company releases products without considering such parameters.
Simply a disappointment.
