Aurora R12, aftermarket cooling options?

Technically speaking you will already have the best. I am not sure why you are looking to upgrade the cooling if you have not used it yet?

Alienware cases can only accommodate a 120 AIO liquid cooler, 1 front intake fan, 1 exhaust fan that also acts as the cooling fan for the radiator.

Some people do change the fans out because that provides a lower noise level, and some people sandwich the AIO rad between 2 fans for a push pull configuration.

Some people are able to squeeze in a second front fan, by removing some items from the case.

The occasional person will change out the 120 mm AIO with another 120 MM AIO.

Just be aware these systems are very picky on what aftermarket hardware they support, and even fans can cause the system to stop booting since it will check if the "correct" fans are installed.

There's basically zero options to really increase cooling on these systems, unless you want to start cutting up the case and installing custom loops. 

My suggestion for more airflow would be to move CPU, GPU, RAM and SSD over to a case with much more cooling options, and a new MB and power supply.

Or start cutting up the case and modding it.

You would void your warranty with either of my suggestions.

There's a thread on here that details the installation of better cooling step by step, complete with pictures.

When you say "upgrade cooling options" if you mean more powerful, you're probably good but can mod another OEM case fan in the HDD doc and a Y adapter for your current fan to allow for the additional input. This would be the best way to upgrade cooling (low temps) IMO. 

If you want a super quiet setup, you can use Noctua fans. A lot of people are ignorantly replacing their OEM fans with Noctua thinking the cooling is better too when actually the top RPM/CFM Noctua fans are much less, about half actually, when compared to the OEM fans. I blame Alienware for not providing specs on OEM fans and making them so hard to find (had to pull out and look at fan company/model no.). 

Here are some links with specs that will help you compare between quiet (Noctua) and power (current/OEM) to see what's right for you. If you go with Noctua, there are a lot of YouTube videos about how to do this right and which exact fans work best for the R12. 

The Noctua fans - 2x quiet and less powerful:

Here's the OEM case fan:

And here are the OEM CPU fans:

The R12 I bought is without an AIO liquid cooling CPU, I'm thinking of getting an AIO, any recommendations for me?, like a better AIO option for the CPU than the regular one, that can fit and work with the R12?

I have the same specs and my gpu runs hot I need to figure out some cooling options as well

There's limited options, and a 120 AIO is all that is going to fit into the case without extensive modding.

These systems are also picky on what 120 AIO is going to work.

I don't thing a different 120 AIO that works well with the motherboard and case is going to make a huge difference.

A 240 would make a difference, but it will not mount or fit inside the case...

Hello, do you know if the OEM fans will fit into the slot created in the front of the case by removing the HDD in the front? Do you know if ML120mm fans will work? Not the “pro” just the regular ML120 fans from Corsair. 

I use 1 Noctua 120 mm that replaced the original front fan, and added an 80 mm Noctua where the 3.5" drive cage is. If you remove the blue plastic caddy, you can take out the metal caddy and it has a bolt pattern for an 80 mm fan.

You can use the y-splitter form the 120 mm Noctua to power up the 80 mm Noctua. They are both the same RPM and Voltage.

Thanks,  is there a link to purchase the Dell AIO for the R12? 

Good to know and thanks.  Are the Noctua fans better than the stock ones? Did you replace the rear fan and add another fan to the additional top exhaust?

The R10 only has 1 top and 1 front fan.

There is no rear fan. 

I replaced the front fan and added a second fan in the 3.5" enclosure in the front. 80 mm fan bolts right in the metal HD cage.

I think if you remove the HDD cage altogether, you can fit a 120mm fan. it can be attached with zip-ties and/or double-sided tape, like Gorilla or Nano, cut into triangles. I've seen a YouTube video.

I think that this is it https://www.amazon.com/EVGA-Liquid-Cooler-Cooling-400-HY-CL11-V1/dp/B07CNXHYJ2/ref=sr_1_1?keywords=asetek%2Baio&qid=1637169867&sr=8-1&th=1

It looks similar and I did about a weeks worth of research to find this, I hope it helps.
