Reverse Cooling (Front Exhaust) project.

It's up and running and the CPU and GPU are averaging 65C under heavy gaming. (Hogwarts legacy @ 2K with everything maxed out)

I do use a custom cooling curve for the GPU. Fan = 0% at 34c, 30% at 35c, 40% at 40c, 50% at 50c, 70% at 60c, 100% at 70c.

So, SUCCESS! It works. All the heat blows out the front and away from the user and the insides stay nice and cool.

There is one issue though, on both pc's. On the i9 base power is 125W and turbo power 253W. I overlooked the cooling needs of the new CPU and my 120MM AIO Liquid cooling setups aren't up to the task.

Both PC's stay cool enough when gaming but that's mostly GPU work. When I stress test the CPU it hits 100c pretty fast and throttles. I've already ordered the first Cooler Master - Master Liquid 240L V2. If I like it, I'll buy another one for the other PC. If I was going to build a PC for CPU heavy tasks like video proccessing with this CPU, I'd go with a full tower with room for a 360mm radiator.

EDIT: The 100C spikes were caused by an error in the default bios settings.

Intel i9-14900K set at 4096W by default!

Anyone running a newer intel CPU should go read this article. I was seeing instant temperature spikes to 100c on the cpu whenever starting a demanding game. I was actually working on something else when I stumbled across this article. The bios gui shown is the exact same one I have. The power...

Conclusion.

It works fine and it no longer gets hot underneath the desk.

This system runs about 4C warmer then my other one with the same mobo, cpu, mem, cooler and traditional upwards cooling flow. It also takes much longer to reach idle temps, more then 90 seconds . (Idle temps <= 40c cpu, 30c gpu) This makes sense since the heat is being pushed through the case instead of directly out.

I've upgraded both PC's to a 240mm liquid cooling solution. After that and changing the power and current limits in the bios they both sit at 98c during stress testing using CPU-Z.

I've also become a believer in positive pressure cooling setups. We live in a very dusty agricultural area. Perhaps you've heard of the San Joaquin Valley - Wikipedia ?

The video, I loved it..

Many years ago I've heard horrid stories about baby mice being in district office PCs at work.

I have my case with every fan facing out. I have two slot covers open in the back. The CPU temp averages about 40c. and the GPU is is about 27c.
