Rated 5 out of 5 by from The Perfect Prebuilt Gaming PC I've only had it for about a month, but WOW. This is the perfect prebuilt for a beginner (but still very powerful) PC. I run games on Steam with no problems, applications and websites load extremely fast, it's super quiet with little to no noise even when playing games; however, I still haven't tried live streaming yet. I suspect there won't be any problems with that though, considering how well it runs everything else. The only thing I've heard about this PC is that it's difficult to upgrade hardware and you'll have to dig around to find something compatible, but I really don't see a need to upgrade if you just want a powerful PC that you plug in, turn on, and start playing. I don't see myself getting tired of this anytime soon, and I don't know if you can get anything better for the price they offer!

Rated 5 out of 5 by from Great Performance with GPU fan adjustments Ordered this PC for my little brother a week ago and he was so excited when it came in. He plugged it in and we played for hours, but he had a problem. Multiple times throughout the day and the day after his GPU would reach insane temps (98C) and then subsequently shut down the computer which would then prompt the GPU fans to ramp up to max to try and cool itself off. This was obviously worrying. So he woke me up and I took a look at it and eventually found the problem, the fan speed was capped at 20%! No idea why, but I guess HP decided that it was better for a computer to be quiet than functional. Anyway, by using the AMD application which was preinstalled on the computer, we set the max speed to 100% and allowed the GPU to use it's fans to cool itself off properly. It isn't going above 65C now so it was clearly effective. We noted a few other reviews that were having the same problem so I thought it would be best to put this here for prospective buyers, you will likely have to increase the fan speed yourself. It isn't hard to figure out and took me about 20 minutes to get working. So if your Omen 40L is overheating and crashing, this may be the cause and thankfully it's fixable.

Rated 5 out of 5 by from Excellent! I'm very happy with my PC's performance on every level. The fans run quietly, everything is super fast, the colors are beautiful and easy to customize, and gaming is a breeze. I honestly couldn't be happier.
