Check if a 120mm radiator suits your GTX 1080.
I've noticed that during gaming with my GTX 1080, it reaches 85°C and to maintain performance I must crank the fan very high via software. I'm considering a custom loop setup, but I'm uncertain if a 120mm radiator will suffice. Installing a 240mm one would be tough because of limited space. Would a compact radiator—such as a copper or brass one—be sufficient for heavy overclocking on this GPU?
Because the 1080 has a TDP ranging from 180 to 220 watts (varies by source), using a 120mm radiator with a low-flow AIO cooler pump pushes cooling limits. To maintain strong temperature differences, flow rates need around .75 or 1.0 gallons per minute; lower flows reduce cooling efficiency, though high-performance fans can compensate. In summary, a 120mm unit with adequate flow tends to outperform the standard air cooler, depending on flow and fan performance.
Yes, more than enough. Most pre built 1080s with 120mm water coolers I have seen barely crack 55c under load. 1080s are voltage locked so even with as heavy of an overclock you could get at stock voltage it wont produce much more heat than it would with stock clocks.
Dunlop0078 confirms ample capacity. Most pre-built 1080s equipped with 120mm water coolers have shown minimal cracking even under heavy load. These units are voltage locked, meaning you can run at stock voltage without generating significantly more heat compared to standard clocks. If you meant hybrid coolers, they only handle the processor cooling here.

If you're referring to hybrid coolers, don't they only cool the processor? this is a full water block and i'm not really knowledgeable here
Well you only asked about core temps, the water block covers the entire GPU core in a hybird card. The fan cools things like the VRM and memory, which generally don't need to be water cooled to work as they should.
With a full cover water block, depending on which one, things like the VRM and memory will be cooled by water. Depending on which card you have you may not even have thermal sensor for things like the VRM and memory.

I will not be buying or setting up a hybrid card. I just need to verify somehow that a 120mm Radiator can cool all features of a gtx 1080 (core, memory VRM).with some overclocking headroom.
Yes, it will. Your temperatures might exceed the typical range for a water loop, yet a 120mm radius still offers significantly reduced noise and effective cooling for that card.
