Hey everyone! I'm pretty new to PC building—this is only my second build. Unfortunately, I had some trouble with my CPU after a year and had to replace it. The building process was quite stressful for me, so I took it to a local shop for assembly. It took more than two months, and they even broke my tempered glass panel during the process. Now that I finally have my PC back, I've noticed that the Noctua NH-D15 fans are not installed like they were before the CPU issue. I'm really worried and just want to make sure everything's set up right. Here's the link to the image I took: https://imgur.com/a/9kOrHTV. Sorry if this sounds silly, but I'm feeling a bit overwhelmed. Thanks for any help!

Yeah, it seems like the fan orientation is off. They should blow air in opposite directions to ensure good circulation. I understand it can be tight in there, especially when installing them. It can be tricky!
It looks like your fans are installed backwards. They should be pushing air out of the case instead of blowing towards the front. Typically, the side fan would go on the right instead of the left. You might want to switch that around for better airflow!

I had a tough time fitting my fans too, they’re quite snug around the RAM. I felt safer trusting the store with the installation, but looks like I should have checked myself!
