I wanted to buy the cooler master MA410P heatsink for my cpu because the stock one is overheating my cpu slightly. The CPU i use is an i5 8400 and my motherboard is the Gigabyte H370 Aorus gaming 3 wifi (rev1.0), and the case i use is the Rosewill Nautilus. On their website it says 154 mm cpu fan size supported however the one i want to get is 158.8 mm. but the case has 194mm width, so im a little confused.
