RX 480 Mosfet cooling
How does it work?
If I want to add a custom cooler to the reference RX 480, then the report says I also absolutely need to cool the mosfets on the board. However, it just tells you to get a mosfet cooler from an older card. I don't have one, so I have to get it from somewhere else.
Will ones like these work? Do they need a specific size? If they're too big, they won't fit, right?

Since they're bigger than the mosfets, I have to glue them on somehow like this, right? Sounds retarded

It works by keeping the temperature lower than what they can handle. We don't know the losses (TDP) MOSFETs have on AMD's boards so can't say shit for sure.
With enough airflow the shit you linked might be okay, but I can't say for sure. I don't know the exact numbers on the area of cooling surfaces nor the power they need to dissipate etc so I can't even calculate that shit.

depends on how "neat" you want it to look
if you are ok with nigger rigged shit, using a couple of nylon strips to secure the passive cooler in your pics would do just fine, that main cooler will blow air over it so its all fine
but if you have some tools (drill + saw) you can fashion something like

from that passive cooler, which you can then mount properly onto the card

That mosfet cooler in the pictures is from an Asus Radeon HD 7970 Matrix Platinum.

Why put a aftermarket cooler on a reference RX 480?

Never knew it was this short. It'd probably make for a good itx build if it wasn't AMD

Reference RX 480 PCB is for retards.

970 was a good ITX card, so the 480 will be pretty good too

This guy has put some huge as fuck heatsinks on them. Didn't find something like those on amazon.
But the refrence is so starved for power why put all this effort into it
lol FETs are such old tech. when are they going to start doing power delivery over the cloud?
