Need Help regarding my PC HP OMEN Obelisk 875-0075na

[Hassan666]

Hello Everyone,

Hope you all are doing great,

I have a HP OMEN Obelisk Desktop PC - 875-0075na. https://support.hp.com/gb-en/document/c06529778

I don't have a vast knowledge of hardware and software but I do have a decent amount of knowledge. 

I love the build as I don't play very graphics demanding game, all I play is Dauntless and Dota sometimes.

I have noticed that my CPU temperature goes to around 80°C and my GPU'S temperature goes to around 83°C and then I start noticing a FPS drop in dauntless and dota too.

The problem is that there is only 1 fan on the casing, one stock fan for CPU and stock fan for GPU. So obviously, thermal throttling is sucking out all the FPS.

The build comes with a 500W Bronze PSU. If I want to install 2 fans with the casing and a CPU Cooler (Air Cooler), will I require a more powerful PSU? as the GPU takes around 160W. (I have an option to buy Corsair RM750 PSU)

Some help will be really appreciated, thank you in advance.

Kindest Regards

Hi Hassan666,

Indeed, heat is your enemy. I wondered if this previous HP Community Forum link applies to your Obelisk as well -please take a look and comment: https://h30434.www3.hp.com/t5/Gaming-Desktops/Where-how-to-install-additional-120mm-fan-in-Omen-Obel...
