Need some help with RX 480 aftermarket cooler

I've got a reference XFX RX 480, and i'm about to slap an Arctic Twin Turbo II on it. Unfortunately the guide that comes with it is of little use, and i'm trying to figure out where to put the heatsinks, for the VRM's.

As far as i am aware, i only need to slap a heatsink on the Red, Purple & Blue sections outlined in the image below. But do i also need to put one for the Green one? And do i need to put anything on the Yellow outlined section?

Yes, on the green one too, don't forget to cool the VRAM too with something like this

for reference check this out if you haven't.

The yellow part doesn't need cooling.

That's already covered as the Arctic Twin Turbo II comes with a variety of heatsinks.

But what about the yellow section i outlined?

Anyway, yes for the green one, no need to cool the yellows.


Looking at all bits and pieces you get with the Accelero, you should have enough crap to mount on everything...
PS If you are that concerned, just go and get yourself extra heatsinks...

Little bit of bad news - can't fit heatsinks on all the ram chips due to the cooler itself. Shouldn't be an issue tbh, it still has air blowing down onto them.

They can't fit because the heatsinks are too tall? If you're bothered by it you can by heatsinks with smaller fins, in terms of height.


The mounting bracket is overlapping like half of the 2 - 3 mem chips, nearest to the GPU...

Welp... at least he can cover the rest of them.

Well, i've got it on. But some issues with it. Plugging the fans onto the GPU doesn't work properly. Wattman & any program i use to monitor fan speeds, give me ridiculous RPM speeds (i mean like 98723456892rpm) whenever it tries to ramp up the speed, causing it to go full retard, then revert back to the lowest RPM.

So i've had to plug it directly into my power supply. But i'm using the 7v adapter, since i don't want the fans running full speed. Doing so, the core temp peaked at i think 74c, this is with a 1300mhz core OC.

The VRMs however... ~50c idle. But running Unigine Valley / Overwatch with the framerate uncapped, peaked at 94c (they're rated at/for 125c so it's still within spec). Not really an improvement over the stock cooler, when it comes to VRM temps, but at least the gpu core is relatively cool.

I've ordered this to manually control the fan speeds, to find the sweet spot between cooling & acoustics. As i'm pretty sure i could have the fan speed a fair bit higher than what the 7v adapter gives, whilst remaining quiet.

Once you get that thing installed and properly working, give us an update!

It'll be curious to see how it compares to some of the board partner heatsinks.

It performs on-par with the Nitro+ RX 480, but with lower idle temps, due to having the fan at a constant 7v as it's being powered via molex using the adapter that it comes with.

I personally would recommend going for any of the AiB cards with non-reference coolers, as it's hassle-free. The Powercolor Devil gets my pick. But for existing reference RX 480 owners, the reduced noise output and lower temps are worth it tbh, since it only cost me £30 for the cooler.
