Hi everyone,

I’m considering to get this router. But I have limited space, can any kind soul help measure the base width?

I checked on Asus’ website, it says 8.5cm. I’m not entirely sure that’s the router width, or base.

Thanks in advance !

For those who are interested to cool AC86U passively, I’ve done it successfully as follows:

1) CPU = 1.8 + 0.5 + 0.3mm 20x20mm copper shim (Sandwiched with Thermal Grizzly Kryonaut)
2) 2.4G CPU = 2x 2mm GELID thermal pad
3) 5G CPU = 2x 2mm GELID thermal pad
4) PCB underside = 5pc, 2mm GELID thermal pad. (Single layer)

4 days average so far:
CPU = 59 (Prev. 73)
2.4G CPU = 46 (Prev. 53)
5G CPU = 50 (Prev. 55)

Hope the dimension will help! It took me couple of weeks to trial & error, ordering copper shim from AliExpress.

Finally get the optimum contact between heatsink and CPU.

1) That's the thickness of copper shim. If you managed to get a 2.6mm ones, then only need 1pc, no need sandwich.

2) yeah. 2mm is thickness. GELID thermal pad has 3 different thicknesses IIRC. Size is roughly (eye-balling) 15x15mm.

[Temp update aft. 2wks, highest recorded. On rainy/night, CPU drops 2-3 degC. Not much fluctuations on WiFi]
CPU = 61 degC
5Ghz = 51 degC
2.4Ghz = 49 degC

Apologies for the late reply. Extremely busy with work.

Unfortunately everything was done in a rush, so didnt manage to capture photo.
In general, you'll just need to remove the heatsink (front, back) then cut the heatpad to size.

I also agak-agak only. But you may use previous measurement as a guideline.

To report back, below is the stats:
2.4G - 46 degC
5G - 50 degC
CPU - 59 degC
Ambient - 30 degC

FW: Merlin 384.19
