Whats a good laptop cooler?

I’m looking out for opinions on what would be a good laptop cooler to invest in. My thoughts are having those huge laptop coolers with an enormous fan or those fans that lets you adjust where the fans are placed? I read somewhere that the laptop coolers are the ones that run off AC adapter than USB powered?
I only had this one in mind below.

NZXT’s Cryo LX is the best in my opinion. Stock fans are not quiet but it’s the best performing cooler out there. I haven’t checked out CMs new storm laptop coolers but they seem very good too.

most should do a decent job
got a $10 cheapy and it cools a lappy with no internal fan (it’s busted) just fine
