acer predator po3-600 i7-8700 need to know what motherboard it has to fix a cpu-heatsink-FAN issue

[Miguel2013]

hi so I need to know the motherboard name or at least what fan for the cpu heatsink I need since the fan is making noises when rpm spins higher than usual and may die any time.
if possibly not get the same but better fan for the heatsink which I will provide photo as soon I can (it's at my brother's house). But I'm sure is the stock heatsink for these models.

the guy has a Noctua NH-L9i but I don't think that would fit as my brothor heatsink has a wierd shape (check photos)
i could take a look at the model of the fan but i wanted if I could get a better fan for the heatsink shape.

A lot of OEM coolers are like this. If you take a closer look, it's not proprietary, it's just the fan on top that's rotated clockwise slightly. The mounting holes on the actual cooler are still the same.

You haven't given any specs or name of the board, but if it's any Intel-based OEM desktop in the past 10 years it'll be using the exact same mounting holes since LGA1156/1155/1150/1151/1151v2/1200 sockets are the same spacing.

The only thing that would stop a L9i from fitting would be if it's a stupid design like Dell in recent years, where the cooler backplate is affixed to the case. Unlikely.
