Question Arctic accelero iii heatsink placement

[Zacny]

Hello again!
I have finally bought arctic accelero extreme iii, and I am trying to install it on my gigabyte 1080ti turbo. I am not sure if my heatsink layout is correct, i was helping myself with photos from the internet, and the old cooler. Can I glue every heatsink by using this 3m thermal tape that I have bought? Its very thin compared to normal thermopads :/
And the last question, do I need to use the insulation tape? If Yes, where?
Here are the photos:

This thermal tape properties:
0,05mm thin
Work temperatures: from - 20 to 130 °C
0,17W/mK

I hope you Can help me guys

Edit.
After removing the stock cooler, I have noticed these weird color makrs on pcb, should I be worried about it?

Well, the old thermal pads were on the chokes, not the capacitors/resistors? between the chokes and the memory. So, you might not want those on there.

Don't really see a reason to use the insulation tape anywhere.

 

[Zacny]

To be honest, I have no idea which one is capacitor/resistor xD If you can show it to me on the photo it would be safer for me.

 

[Eximo]

You covered them with heatsinks, I can't tell either. I see what looks like some large film capacitors or diodes (black) peaking out (no idea why there would be diodes) what look like surface mount capacitors next to them in pairs (yellow/brown)

If you look at the thermal pads closest to the memory, that was on top of the chokes. Those are the little gray boxes. Inside of the casing is a copper coil.

There is no thermal pad directly between the memory and the next thermal pad, but that is where you have placed heatsinks. Presumably those parts don't need cooling.

Ok, I think I know what you are talking about, also I have posted photo without these heatsinks, here is the link : https://ibb.co/f4x3Cr6
What do you think about that thermal tape? Can i use it? And are these weird colors on pcb?

 

[Eximo]

Yep, capacitors. Given the type, heatsinks probably wouldn't hurt anything, but they are also already encapsulated and really don't need cooling. The chokes don't really need cooling either if there is going to be a fan blowing down on them. They are usually hooked up to the thermal solution as an extra way to get heat out of the PCB.

Thermal tape is fine I suppose. I used the included thermal adhesive when I last owned an Arctic Accelero Hybrid.

Not sure what weird colors you are referring to, everything looks normal to me. A little dust around some of the mounting holes.

If you mean the color of the GPU itself, purple and iridescent shades are pretty common for silicon dies.

Ok, now it looks like this:

If it s correct, im going to install everything

And about weird color, I am reffering to these weird stains:

Ah, that is just goo from the thermal pads and/or solder paste residue that leaked out from under the memory chips. A little isopropyl alcohol will clean that up.

 

[Zacny]

Okay! Thank you very much! Im going to install it right now, and I will post results later here

Update, I have decided to use glue, and thermal pads included with cooler, what do you think about it?

[Eximo]

Thermal pads are intended to go between things, probably intended for the memory, not to be used as an adhesive. Those heatsinks will likely fall off.

If you are going for it, use the adhesive on all the heatsinks.

Thermal paste for the GPU itself, of course.

 

[Zacny]

Thank you for the reply, I will glue it too then.

UPDATE
I have installed everything, GPU works... But the fans dont spin, also i have noticed that my accelero arrived without 4 pin adapter:

I have tried to insolate these 4 pins and connect it directly, but still nothing, what can I do? I really need my pc working tommorow :/
Oh, also there is no molex adapter in the box...
