Airflow Advice

[Blytz]

Thank you in advance for any advice given, airflow is not a strong subject for me.

I bought a prebuilt PC (not from OC) 2.5yrs ago which is a Corsair 4000d airflow case housing a MSI B550-A pro, Ryzen 5800x, RTX3070 and 32gb RAM. The fans were noisy so I replaced the stock ones sent with Corsair ML120 but kept the same case configuration. I am considering upgrading the GPU to a 7900XTX/4080/4090 (plus new PSU) but challenge the value. However I want to use my 4K TV to game so have hooked it up as a second screen but only displaying on 1 monitor at a time. I appreciate this will stress the system and increase temps but also feel it has brought to light airflow issues.

I have failed trying to upload a picture to illustrate so will try and describe:

- 3 intake fans on front of case, AIO radiator on top two
- Rear exhaust
- No fans on top of case
- GPU located midpoint of middle fan

I know that I will need to move the AIO radiator to the top of the case to make room should I upgrade the GPU, but my questions are whether it is worth:

- Moving AIO now and adding 3x new fans to front of case
- Changing the fans I am using

I like to keep the PC as silent as possible and would pay extra to keep the db as low as possible.

Thank you for reading!

Thanks for replying. Yes, if I move the AIO to the top I’ll have 2 spaces at the front.

I’ll get some more fans and see the difference in temps.

You could also change the rear exhaust to an intake so your feeding cool air straight into the aio.

Thanks, I’ll try that when the new fans arrive.
