Sorry, but after warranty support isn't poor, it's jsut expensive. What many discover is that there is no free "please look at this" or "can you tell me what to do". And the result is about what you post.
Repairs run from 10% to full price of the laptop and this is why people feel the service is poor.
As to your issue, you have to make the decision that it's worth paying to have it fixed or not. I can't make this decision for you. It is possible that you could fix it yourself, but it may involve you opening up the laptop, finding a loose heatsink, dead fan and hunting down a replacement part.
Another complaint about all the laptop makers is the parts issues. You can't buy just the part you want because HP/others don't buy just that part. The LCD is a find example. You can't get just a cable since they buy the LCD, covers, power modules, CFT and more... with the cable attached. This leads to more fingerpointing that parts are hard to get...
Best of luck solving your issues. As to finding complaints, you'll find that with all makers since it's the nature of "how it is".
