their PC destroyed due to LC, I'm not sure if it was due to the liquid s[censored]ing or not
being replaced? I have some idea of how it works, but what's benefits and drawbacks VS ordinary thermal cooling fans?

Liquid has much higher thermal capacity than the far less dense air, hence it is more effective at moving heat away from the cold plate.
Air cooling is the cheapest alternative and is safe so even if a fan fails (which definitely doesn't happen to often) heat will dissipate naturally from the heat sink. It will also be easier to catch these failures before it causes system damage. The main drawback is lack of thermal performance compared to the liquid cooling counterparts. More performance = more heat = need for more cooling capacity.
Liquid cooling cant really be beat as far as thermal performance but costs quite a bit more. If you need excellent cooling or live in constantly hot areas then liquid cooling may be a bit more appealing. Or if you are crazy about overclocking then liquid cooling is basically a requirement. Main drawbacks would be initial setup as these systems are larger and contain more components (except all-in-ones) and have higher margin for failure. Funny/sad story my corsair h110i GT pump failed literally two days ago and caused my temps to hit 92c!!! Thankfully i was able to shutdown before there was any real damage.
Cant really go wrong with good old fashioned air cooling. There are some very competitive solutions out there starting with the ever so popular Hyper 212 EVO from coolermaster. But of course with the need for performance liquid cooling will always sit at the throne. If looking into getting a liquid cooled setup start with a solid AIO setup and go from there. Frostytech.com is one of the best places for cooling component reviews and have an awesome test setup. AIO's can deliver good performance for the price. When going from there custom loops get much more expensive and harder to setup but have the best thermal performance. However not always recommended for people who havent set one up before. But hey, thats what youtube is for right? Hope this helps anybody.
That's quite a lengthy explanation, I have heard horror stories about liquid cooling and I guess there is some risk to it, but I would definitely say that overclocking is essential, I think I will start out with just a liquid cooled CPU and then liquid cool the GPU, thanks for the explanation.
