Now with Intel Z590, H570, B560 LGA1200 motherboards, AMD X570, B550, W480 Socket AM4 Ryzen motherboards as well as many more motherboards and many new coolers! Also new is the integrated share button!

Since 1999 we have been testing coolers and motherboards on OCinside.de and check which CPU cooler can be used for which motherboard. With the interactive Fit for Fan guide v3.3 you can find out with a few clicks by trying the desired CPU cooler virtually on the selected mainboard. You can not only see which CPU cooler fits on which motherboard and how much space is left for the remaining components. You can also see what it costs, how the cooler sounds and how good the test result is.
