Modem Cooling Question

In the pic on the left you see the heat sink with a thermal pad on the bottom and on the right you see the processor. What I'm not sure about is if that's the exposed die or if it's like a tiny IHS and either way why you would want the thermal pad to cover it entirely like that. Do you think it would help its cooling if I took the pad off and applied paste to just the presumed die instead?

that's a thick pad. I doubt you'll get contact without it.

It's a bare die. The thick pad is probably to lower the risk of cracking it. If you replace the pad with paste, be very, very careful when installing and tightening it down.

Yes that's the bare die.

No, you won't get better performance with paste, at least not without modding the heatsink or using. Those posts, which are there to lift the heatsink so it doesn't hit the transformer IC, means there is a gap too large to bridge effectively with paste.

You could make direct contact if you used a an aluminum orcopper shim to fill most of the gap, which would significantly reduce thermal resistance when used with paste...but I wouldn't bother unless you have good reason to suspect there are thermal issues.

You'd probably be better off adding a small fan to the modem. Or as they say, go big or go home!

No way, this is the air cooling forum
