A:AnswerThe base fans are good. As the CPU is liquid-cooled mainly just for the GPU. I personally like my rigs to be as cold as possible so I installed 3 more Corsair LL RGB fans.
A:AnswerNvidia recommends a 750 watt power supply and this computer has an 800 watt PSU, so you should be fine. But you wont have a lot of headroom to add additional components.
A:AnswerHello, HP recommends using Crucial.com for your upgrading memory needs. You can also speak with the HP Support department to assist you with questions regarding the internal components. HP Support can be reached by phone at 1-800-474-6836. Thank you for being an HP customer!
A:AnswerThat would normally be considered non-upgradeable or non-changeable part. You could try contacting HP Support or Geek Squad and see if they offer that as a service. It would not be recommended to attempt to do this on your own. Changing the motherboard is considered high risk and can easily lead to the computer or laptop getting permanently damaged.
A:AnswerNot that I have found. But I had really good luck buying used Ram from Facebook Marketplace, you can also find it on ebay. Just make sure it came from an HP Omen PC, or it might not give you the correct speed.
