Are laptop cooling units units worth it? I'm debating getting one.
Yes, especially if you are gaming. Nevertheless, they are good even for every day computing use.
What would be the estimated price of one that actually works?
I bought a generic one off of eBay four years ago that still works to this day. It was $20.00. Bought one for my daughter's college laptop from Five below for $5.00 and works fine.
Works great and you can't beat the price.
Don't buy what CAMusing recomended. I have had one like that and it was not good. I recomend you buy one with coolers.
If you can hear the CPU fan running most of the time, then you do need a cooler.
This one is well thought of by users;-
