Sounds like you watched the Phil's Computer Lab video. I've never really been bothered by the stock fans in my HP 6300 MT as I have them spin down to a lower RPM (500) by lowering the fan idle mode. As a test I unplugged both the front and rear case fans and found that I could barely hear the PSU fan. So I really have no reason to replace that. If you test this way and the PSU fan is not too loud, just replace the front 92mm fan with the Arctic. Another option is to just buy a replacement HP SFF PSU that has a fan in better condition. They are dirt cheap on Ebay and you'll always have a backup PSU on hand if you ever need it.Having done a CMT and USDT version of these I'm now working on a SFF version. Just seen the details on replacing the front (CPU) fan which is great and will work on obtaining one of those. Has anybody replaced the PSU fan as well with something quiet? Yes I'm aware opening PSUs can be dangerous...but happy to be careful
So the first step is to just replace the front CPU cooler fan and see if you can live with the noise level after that swap. If you do change the PSU fan to make the noise levels lower, avoid touching the rectifier, capacitors etc. In the video Phil says the process is the same as replacing the front case/cpu fan. Take out 4 screws, install the fan and connect the 4 pin connector. He didn't mention any need to cut cables and do any soldering of wires. So it should be straight forward. Of course, this must all be done while the PSU is removed from the case and the power cord completely removed. Be aware of the risk of electrical shock when doing this and take all precautions to prevent that. I don't recommend that anyone do this procedure still, I know that some will want to try and get a quieter PSU.
