I actually took apart my laptop today and replaced the thermal paste, the old paste was actually hard so I'm glad I went ahead and did it.
I run a i7-3610qm and 660m and I benched it at about 83C with the paste that was on it, 70c after putting on new paste. Which seems like an over large jump.... especially when I didn't have any dust build up.
I would suggest looking to see if your cooling fan is even working, 103C is very high....
Liquid metal, depending on the metals used, can react with certain other metals. For instance, Conductonaut will react with aluminum coolers, essentially ruining them.
Aside from that, modern liquid metal TIMs are fairly easy to functionally
remove. You'll likely never get it completely
off, but that is really only a cosmetic issue.
They also last a rather long time as long as the thermal cycling isn't too extreme. The problem is, under extreme lows, they can crack, and under extreme highs, they can reflow.

I have read that liquid metal TIMs are close to impossible to remove once applied and that they actually lose a lot of their cooling capability after a few months. Not saying that is correct, the truth is I don't know much about them. Are they applied the same as a standard thermal paste?
I was actually set on the AS5, but it performs worse in benchmarks, perhaps because it requires time to reach its maximum performance.
The cooling system is terrible, the CPU and GPU share one fan that starts to actually work at over 80 °C, only runs at its highest RPM when throttling and can't be controlled manually. Running it at its maximum speed (which does generate a fair amount of noise) would probably decrease temperatures by a lot.
The CPU (an i7-3630QM) only reaches 103 °C after running at 100% for a little while. Right now, I've got it locked at 2.4Ghz and the temperature is varying between 54 °C and 63 °C (oddly enough, the second core is always between 3 and 8 degrees lower than the others). The room temperature is quite high as well during summer, 27 °C currently.
AS5 is a popular choice, mainly because it got some great press 15 years ago when it was actually one of the better performing options, and people don't easily let go of old habits. It isn't actually a good paste by modern standards though. It loses in literally every metric to newer pastes like MX4. While there are certainly worse pastes still on the market, much superior ones are also readily available, and usually for a lower cost to boot. There simply is no reason to buy a new tube of AS5 today, although if you already own some, and are on a tight budget, it'll do.
